Q & A
在美国哪些州可以合法使用娱乐大麻?
-根据最新的信息,美国有25个州和华盛顿特区允许娱乐大麻的使用。这些州包括阿拉斯加州、加利福尼亚州、科罗拉多州、缅因州、马萨诸塞州、密歇根州、内华达州、俄勒冈州和华盛顿州等。此外,还有几个州允许医用大麻的使用,并且有些州已经将大麻的使用去罪化。具体每个州的法律可能有所不同,因此建议查阅最新的法律条文或相关资源以获取详细信息。
如果每天吸食大麻一个月,是否会有戒断症状?
-是的,如果一个人长时间且频繁地使用大麻,例如每天使用,那么在突然停止使用后可能会出现戒断症状。这些症状可能包括渴望、情绪波动、焦虑、睡眠问题、食欲变化、头痛和其他身体不适。戒断症状的严重程度和持续时间因人而异,有些人可能会经历轻微的症状,而其他人可能会有更严重的反应。
大麻对心理健康有什么影响?
-大麻对心理健康的影响因人而异。一些研究表明,长期使用大麻可能会增加心理健康问题的风险,尤其是对于青少年和有精神病史的人。大麻可能会加剧焦虑、抑郁和精神病症状。然而,也有研究表明,对于某些人来说,大麻可能有助于缓解焦虑、PTSD和其他心理健康问题。重要的是要意识到大麻可能会与某些精神药物发生相互作用,可能会影响这些药物的效果。
大麻对记忆力有什么影响?
-大麻对记忆力的影响主要体现在它可能会影响海马体,这是大脑中帮助处理新记忆的部分。研究表明,大麻的使用可能会导致短期记忆问题,尤其是在使用后的一段时间内。长期和频繁使用大麻可能会对年轻人的海马体发育产生影响,但这种认知障碍需要更多的研究来确定。
大麻是否会增加体重?
-大麻可能会增加食欲,这通常被称为“大麻饥饿症”。这是因为大麻中的THC可以影响大脑的下丘脑,导致用户感到饥饿。此外,大麻还可能导致增加食欲的激素Ghrelin的产生,从而使进食体验比平时更加满足。然而,尽管短期内可能会增加体重,但长期研究表明,定期使用大麻并不一定会导致体重增加。
大麻是否会上瘾?
-大麻确实有可能导致依赖性,但与某些其他物质相比,其成瘾潜力通常较低。只有大约10%到20%的日常大麻用户可能会发展成依赖。依赖性的发展与使用频率、剂量和个人易感性有关。尽管如此,大麻的使用障碍确实存在,并且可能需要专业的治疗和干预来解决。
大麻对肺部健康有什么影响?
-长期吸烟可能会对肺部健康产生负面影响,包括增加痰液产生和影响呼吸道细胞。尽管大麻烟雾可能不像烟草烟雾那样致癌,但它仍然含有可能对肺部有害的化学物质。一些研究表明,大麻吸烟者比非吸烟者更有可能经历呼吸道问题,但目前还没有足够的研究来确定大麻烟雾是否会导致肺癌。
大麻对工作表现有什么影响?
-大麻的使用可能会影响工作表现,尤其是在需要高度集中注意力和快速反应的任务中。大麻可能会减慢反应时间,影响动机和注意力,这可能会对工作表现产生负面影响。然而,这种影响通常是暂时的,并且在最后一次使用后的12小时左右可能会恢复正常。
大麻对情绪有什么影响?
-大麻可能会引起情绪变化,包括增加焦虑、抑郁和情绪波动的风险。然而,对于一些人来说,大麻可能会帮助缓解焦虑和压力,提供一种放松的感觉。大麻对情绪的影响很大程度上取决于个人的使用模式、剂量和个体对大麻的反应。
大麻对社交焦虑有帮助吗?
-大麻可能会对社交焦虑产生不同的影响。对于一些人来说,它可能会减轻社交焦虑,提供一种放松的感觉,使社交活动变得更容易。然而,对于其他人来说,大麻可能会增加焦虑感,导致社交场合中的不适和紧张。因此,大麻对社交焦虑的影响是个体差异很大的,并且可能取决于大麻的剂量和个人对大麻的敏感性。
Outlines
🌿 Legalization and Perception of Marijuana
The script begins by questioning the effects of daily marijuana use for a month, focusing on both physical and psychological impacts. It highlights the changing legal landscape with marijuana being legal for recreational use in many US states and territories, and decriminalized in others. Public opinion leans towards acceptance, with a significant majority supporting legal and medical use. The script challenges past negative propaganda, such as the film 'Reefer Madness,' and discusses the drug's current social acceptance, even in traditionally conservative places like Thailand, which is experiencing a 'weed explosion.'
🧠 Psychological Effects and Individual Reactions
This section delves into the psychological effects of marijuana, addressing myths about its capacity to induce violence and the reality that it's less likely to cause aggression compared to alcohol. It acknowledges potential antisocial behavior and the increased risk of psychosis, particularly among those with a predisposition. The script emphasizes that marijuana's effects can vary widely, with some users experiencing paranoia and anxiety. It also touches on the drug's impact on memory and cognitive function, suggesting that while short-term memory might be affected, long-term cognitive impairment in adolescents is a subject that requires further research.
🍔 Physical Consequences: The 'Munchies' and Body Changes
The paragraph discusses the physical effects of marijuana, particularly the induction of hunger known as 'the munchies.' It references studies on rats and humans that suggest THC can increase hunger by affecting the brain's hypothalamus and hormone production. Despite potential weight gain, the script notes that regular marijuana users may not necessarily become overweight in the long term. It also addresses the impact on motivation and reaction times, suggesting that while marijuana use can temporarily reduce motivation and slow reaction times, these effects may lessen over time or after a break from use.
🚬 Long-Term Smoking and Respiratory Health
This section focuses on the long-term effects of smoking marijuana, including potential damage to the lungs and the increased production of phlegm. It compares the risks of smoking marijuana to those of tobacco use, noting that while marijuana smoke may not be as harmful, it still poses risks, including the potential for lung cancer and emphysema. The script also mentions studies that have found higher rates of emphysema in marijuana smokers compared to non-smokers and tobacco smokers. It concludes by acknowledging the complexity and the need for more research to fully understand the risks associated with marijuana smoke inhalation.
🔥 Vaping, Addiction, and Quitting Marijuana
The script addresses the emerging trend of vaping marijuana and the associated health concerns, such as potential links to chronic lung disease and asthma. It also explores the concept of marijuana addiction and the reality of withdrawal symptoms, which are generally mild compared to other substances. The paragraph highlights that while dependence is possible, it is less severe than with substances like alcohol or benzodiazepines. It concludes by emphasizing the importance of personal assessment and moderation in marijuana use.
💭 Personal Experiences and the Quest for Self-Knowledge
The final paragraph shares personal stories of individuals who have quit long-term marijuana use, detailing their experiences with withdrawal and the changes they noticed in their lives, such as improved dreaming and mood. It underscores the importance of self-awareness and education when it comes to marijuana use, encouraging potential users to approach the drug with caution and to consider its effects on their mental health and overall well-being.

Transcripts
Can smoking the devil's lettuce every day for a month be bad for you?
What happens to your body exactly, or more importantly, what happens to your mind?
And what if you suddenly quit?
Will you pay for your month of indulgence with a nasty withdrawal?
Humanity has come a long way where weed is concerned.
It’s now legal for recreational use in 25 US states, plus three territories and Washington
D.C.
A further seven states in the US have decriminalized it, meaning it’s not legal, but you won’t
be prosecuted for taking it.
This trend towards general acceptance seems to align with the general public’s opinion.
Surveys show that 88% of Americans think it should be legal for recreational and medical
use.
The world is changing.
It seems like it won’t be long until weed is legal or decriminalized in many more countries.
That’s because word on the street is that weed isn’t half as bad as those Puritans
from the past made it out to be.
Even some of the strictest nations where drugs are concerned have done an about-turn on weed.
We imagine a few of our viewers have been to Thailand in the last year and seen what
has been nothing short of a weed explosion, and this is a country that not long ago could
have put you behind some very nasty-looking bars for having a few grams of weed on your
person.
Entire streets these days in the tourist areas look like a fantasy dream of the deceased
Bob Marley.
Weed shops are everywhere.
It feels like walking through a weed wonderland.
The BBC called it just that, interviewing a guy who said the country is now “Amsterdam
on steroids,” but despite it being a veritable cash cow, there have been people, including
doctors, calling for a re-ban.
The government doesn’t look like it will change its stance.
Surely, if this is happening in conservative Thailand, weed can’t be that bad for you…
That’s what we’ll try and figure out in this video.
Let’s start day one by exploring some myths about this once-demonized drug.
One theory states that weed can make you mad, mad as in the angry type of mad.
And maybe even on your first day of smoking, making it extremely relevant for our 30 day
journey.
There have already been news articles in Thailand saying someone viciously attacked someone
else, and the now-legal weed was blamed.
Some of those stories reminded people of a long-gone era when misinformation about drugs
came out of almost every politician’s mouth.
In the past, we humans absolutely got weed, aka ganja, pot, grass, and herb, all wrong.
You only need to look at anti-weed propaganda films like 1937’s Reefer Madness, which
told us that weed had “its roots in hell” and if it doesn’t turn you into a killer
or compel you to sleep with the first person you see walking down the street, it’ll render
you in a state of “hopeless insanity.”
Here’s a line from a doctor in the movie explaining what happened to some kid who got
himself “addicted” to weed.
“Yes.
I remember.
Just a young boy...under the influence of the drug...he killed his entire family with
an axe.”
This line is the definition of nonsense.
You don’t even need the numerous scientific studies to tell you weed doesn’t usually
make people violent, unlike the very legal alcohol.
As the American comedian Bill Hicks once joked, “Pot is a better drug than alcohol.
I'll prove it to you.
You're at a ball game or a concert, and someone's really violent and aggressive and obnoxious,
are they drunk or are they smoking pot?”
That’s hardly scientific; it’s just an observation, but the people of the world would
very likely agree the answer is without a doubt alcohol.
With weed, there have been some studies that have suggested it could cause antisocial behavior.
One such study published by the National Institutes of Health told us, “A meta-analysis found
the risk of perpetrating violence was more than twice as high for young adults who used
marijuana.”
Another piece of nonsense we like is when President Ronald Reagan, during his war on
drugs days, said, “I now have absolute proof that smoking even one marijuana cigarette
is equal in brain damage to being on Bikini Island during an H-bomb blast.”
He was speaking absolute balderdash, but that doesn’t mean weed is completely safe where
the well-being of your body, or your mind, is concerned.
No drugs are 100% safe.
Before we get into the effects of weed smoking after day one, there’s something we need
to tell you about weed in general: the fact that it just isn’t for everyone.
And we mean, some people might have a very bad reaction the first time they take it,
especially if they do as many impressionable teenagers do, and get blasted before they’ve
checked they have a vehicle (brain) suitable for space travel.
You need to know that weed is a psychoactive drug.
It affects your nervous system.
It can alter how you think, what you see, and what you hear.
It gets you high.
How high is up to your tolerance, if you have a tolerance, and your unique body, and, of
course, what kind of weed you’ve been smoking?
It’s well known that weed today is often about ten times stronger than weed from half
a century ago.
Some people seem very sensitive to weed, and being very high can be almost like tripping
on psychedelics, not always very pleasant, yet others might feel a sense of well-being
but not be all that out there.
We all react differently.
Start slow, is our advice.
There are 483 known compounds in weed, but the ones most talked about are tetrahydrocannabinol
(THC), the one that is mainly responsible for the high, and cannabidiol (CBD), the one
presently being sold as a possible antidote to anxiety and depression or a cure for pain
and various diseases.
We’ll get back to this topic soon.
Weed might not be for you at all, and we mean, for some people, there’s just too big of
a risk.
There is evidence that it can cause psychotic experiences, especially if you’ve had them
before or they run in your family.
It’s rare, but be aware.
There are plenty of scientific papers that tell us cannabis is a known risk factor for
schizophrenia.
Still, according to one such paper published by the National Institutes of Health, “biological
events and a valid model of neurobiological mechanisms are lacking.”
That means they weren’t able to figure out what was going on in the brain when something
went wrong.
They couldn’t find the actual cause.
Nonetheless, it is well established that people on weed may become deluded – paranoid.
If you smoke weed and you begin to think all your friends are CIA agents who are trying
to control your mind in the 21st century’s version of MKUltra, you might be one of those
people who should stay away from weed.
We don't think the CIA does such things anymore.
For some, the craziness is fleeting.
They might find after a particularly large dose, they tell their friends, “Look!
My thumbs have gone weird.
My heart is beating like a BEEPED-up clock.”
That’s from an old cult classic comedy movie with some really funny weed parts.
It’s a film, but the writer obviously had experience with the drug in question.
Put your hand up if you've ever sneakily felt your heartbeat on weed because you imagine
something ain't right…
It can cause anxiety, and with some people, severe anxiety, leading to outlandish thoughts
about something that’s gone wrong with their body.
Again, we know some of you are now nodding your head.
Studies have shown long-term use of weed may increase the risk of heart issues, but it
doesn't cause your heart to beat fast enough it fails just after one smoke.
That's the anxiety talking.
Others say weed makes them feel disconnected from themselves (dissociative), and they may
hallucinate or just have some really disturbing, otherworldly thoughts.
We’re not trying to scare you, but this is stuff you ought to know.
It’s hard to understand how many people in a population will have a negative weed
experience.
In a Danish study consisting of thousands of people, the researchers said 30% of participants
who’d had a psychotic experience in their lives would likely not have had one had they
not ever ingested weed.
Still, many people will not have such negative psychological reactions, especially when they
take it in small amounts.
Millions consume weed every day, and they are a-okay.
A world drug report in 2013 said 180 million people had tried weed in the last year.
It’s thought there are about 219 million weed smokers on the planet right now.
The CDC says about 11.5% of Americans smoke it or did so in 2021.
In England and Wales, a study said 13.5% of 16- to 24-year-olds had it in the past year.
40% of those people said they’d used it at least once a month.
Most of them would have been fine, but some of them would have had negative experiences.
Another study we found said people who smoke weed are three times more likely to believe
people will harm them than people who don’t smoke weed.
Then, there was the study that tested people with an intravenous 1.5mg dose of either THC
or a placebo, meaning nothing.
The researchers found that the weed consumers were 30% more likely to have some amount of
paranoia.
Other negative experiences included lowered mood, worry, anxiety, and negative thoughts
about themselves.
So, with all that in mind, you should start slowly with weed and see how it goes.
Let’s say you like it and want to smoke again.
Day one of weed is over.
It’s now day two.
You may have noticed some forgetfulness, especially around the time you smoked the weed yesterday.
Unlike those times you were wasted on alcohol, you haven’t woken up in a strange bed with
a penis scrawled on your cheek, but your memory is a bit fuzzy from around the time you smoked.
There’s a reason for that.
Cannabis affects something called the hippocampus, a part of the brain that helps you process
new memories.
Studies on rats that were given regular doses of weed showed they struggled to remember
how to do various tasks.
There was even long-term impairment, but these rats were stoned throughout their entire young
lives.
You are not a rat and haven’t been smoking weed for years on end, but this is something
to bear in mind.
Studies have shown that regular weed use in young people can affect how the hippocampus
develops, but such cognitive impairment, like many things related to weed, needs to be studied
more.
Your month on weed almost certainly isn’t going to change the structure of your brain
in any significant way for the rest of your life.
You may have some short-term memory problems when you get stoned again today, but you don’t
need to sweat the long-term stuff yet.
In fact, some studies have shown regular weed use may help stave off neurodegenerative diseases
that affect memory, like Alzheimer’s and Huntington's Chorea.
Let’s say you’ve now been hitting the weed for five days on the trot.
Sure, you have some patchy memory days, but in general, since you’re the kind of person
who likes weed and has positive experiences with it, you actually feel fine.
You haven’t really experienced any changes.
We mean, the middle-aged, long-haired guy that’s been selling it to you, the one who’s
always wearing that old Ween t-shirt, says he’s been smoking every day since 1997,
and he says he’s fine.
Well, he does seem to have some motivation issues.
Many people do, which is why Afroman wrote the song lyrics:
“I was gonna clean my room until I got high/I gonna get up and find the broom, but then
I got high/My room is still messed up, and I know why.”
Again, that’s not scientific, but many people have said such things.
We’ll come back to the topic of motivation soon.
Another thing you’ve noticed is you’ve put on a few pounds.
As the rapper Master P said in a song: “You the captain, I'm the crunch you got
that dinner, I got the lunch.
Hit the weed, pass the blunts.
Your eyes red, you got the munchies.”
A paper in the journal Nature, again based on stoned rodents, said the THC in weed can
cause changes in the brain’s hypothalamus, tricking the rat into thinking it is hungry.
There’s evidence that smoking weed can lead to an increase in the production of the hormone
Ghrelin, which can create hunger pangs.
Not only that, but weed leads to increases in the feelgood chemical dopamine, so the
experience of eating that food could feel much more satisfying than normal.
If you’re a weed smoker, we don't need to tell you this.
You’ve all raided the fridge at 2 am like a ravenous zombie after getting the weed munchies.
Still, while you’ve put on a few pounds, studies have shown that regular weed use does
not generally lead to weight gain in the long run.
In fact, some studies show pot smokers might have a lower body mass index on average.
We should just add here that there are so many studies out there, and so many are contradictory,
that figuring out the mystery of weed is going to take a lot more work.
You could literally spend a day googling all the good stuff about weed and think it was
the answer to all the world’s problems.
You could do the opposite and soon become scared out of your wits.
It’s always best to analyze various studies or at least know they exist.
Let’s also remember here that people wouldn’t do it if it didn’t make them feel good.
As the book (and movie) Trainspotting said about an illegal substance, not weed, but
it works for all substances: “People think it's all about misery and
desperation and death and all that [BLEEP], which is not to be ignored, but what they
forget is the pleasure of it.
Otherwise, we wouldn't do it.”
Sticking with the positives, for many people suffering from chronic pain, weed has been
a Godsend.
You yourself have had neuropathic pain in your back for years, but now you’ve been
smoking weed for a few days, there’s been a considerable reversal of pain levels.
The reason for this is that a person’s peripheral nerves, the nerves that detect pain sensations,
contain lots of receptors for cannabinoids.
Scientists now think that cannabinoids might block peripheral nerve pain.
Studies have shown this to be true in animals.
Still, as you might know, the mind plays a big part when it comes to pain.
You may have heard of the nocebo effect when people feel pain when they shouldn’t be
feeling pain.
A good example is the case of the guy who went to the ER with a long nail stuck through
his work boot.
He was screaming and screaming, telling doctors that even the opiates they were giving him
weren’t working.
When they finally sawed his boot off, they saw the nail had actually gone through the
gap between his toes.
Embarrassed, the guy was suddenly pain-free.
But for him, he really did feel that pain.
And with cannabis, there’s now good evidence that it can act as a placebo where pain is
concerned.
Studies have shown that when people with pain took a placebo that looked, smelled, and tasted
like weed, they felt a reduction in their pain levels.
We’ve known for decades that when someone takes a placebo for pain, certain neurotransmitters
are released in the brain, including what are called endocannabinoids.
But there have also been some negative reactions, especially now you’ve been smoking it for
ten days.
You seem to be less motivated.
Studies have shown that after weed consumption, people can indeed be less motivated.
One study showed that participants who’d had weed were less likely to press buttons
for a reward.
Still, this study showed that if people waited 12 hours, their motivation returned.
Now you’ve realized that taking a long break from weed smoking is sometimes good.
Long-term smokers of weed don’t need studies to tell them overdoing it can make them a
bit sluggish and not exactly in the mood to get things done as fast as possible.
It’s the same with reaction times.
You’ve noticed that when you’re stoned, you may float like a butterfly but not exactly
sting like a bee.
Researchers have said that this might have something to do with the brain's thalamus-corticostriatal
circuit.
The Nature Journal tells us this controls “movement execution, habit formation, and
reward.”
Receptors in here bind with THC, and this can slow down someone’s perception of time.
In a study in 2012, scientists said 70% of participants who smoked weed experienced what
seemed like a stretching of time.
Time moved more slowly, and this might have something to do with slowed reaction times.
Studies have shown that performance can be affected.
These are controversial studies, given people smoke weed and drive cars or operate planes
or machinery.
One study we found showed that when users had to perform a task after ingesting weed
for four days, only had slower reaction times on the first day of the experiment.
It seems that they got used to it.
Another study, a meta-study, concluded, “Some lower quality studies have reported ‘next
day’ effects of THC on cognitive function and safety-sensitive tasks.
However, most studies, including some of higher quality, have found no such effect.”
But you’ve been taking it easy, so your reaction times are not that different from
usual, certainly after 12 hours from your last smoke.
You also seemed much more prone to slowness on the first few days you smoked.
This seems to be getting better the more days you smoke.
Like most people in the world, the effects seem to completely go away between two and
four hours, but another thing you’ve realized is that after 12 days on the stuff, you’ve
started to get more anxious.
This is because a part of your brain called the amygdala is stimulated by weed.
The studies on anxiety and cannabis use can be very contradictory.
For some people, weed helped with their anxiety, but for others, they experienced an increase
in anxiety after long-term use, although the causal links were not clear.
In a 2017 survey consisting of 9,000 American regular weed smokers, 70% said it gave them
noticeable health benefits, with almost 50% saying it relieved anxiety.
Others said it helped with their PTSD.
Some said it had a positive effect on their phobias, and some said it helped with sleep
and social anxiety, but others said it caused anxiety, especially when they consumed weed
with high levels of THC.
It’s a bit of an each-to-their-own situation.
In your case, the anxiety has only been fleeting, and you only experienced it when you had consumed
a lot more weed than usual.
It’s around this point in your 30 day experience that you notice the effect weed is having
on your lungs.
This is mostly a silent effect, although admittedly, the other day, you coughed up something that
made you think of the movie Ghostbusters.
Just be aware that chronic weed smoking can increase phlegm production.
You’ve been smoking for quite a while now, and this might have affected the cell linings
of the large airways in your body, which has led to coughing up that ball of slime.
Still, you don’t mix the weed with tobacco as many people in the UK do when they often
make those huge baseball bat spliffs in their Rizla-based works of art.
The question is, is smoking weed safe just because you don’t mix it with tobacco?
A 2021 study showed that 44% of Americans believed that smoking weed every day is better
for you than smoking cigarettes every day.
Of course, the amount you smoke matters.
People generally smoke way more cigarettes than weed joints.
Still, smoke from weed is still not great for you.
Scientists say it may still cause lung cancer and emphysema.
The problem is scientists haven’t figured out just how bad weed smoke is for you.
Not enough studies have been done, something we’ve seen a thousand times while researching
this show.
One of the studies was conducted at the Ottawa Hospital General in Canada.
Researchers compared 150 lung scans from weed smokers, tobacco-only smokers, and non-smokers.
The researchers reported that rates of emphysema, meaning an inflammation of the airway, were
higher in weed smokers than they were in tobacco smokers.
Still, we are talking about 75% compared to 70%.
Only 5% of non-smokers had it.
As for the big C, the Mayo Clinic says cannabis “may” cause lung cancer, but there’s
not enough evidence right now to say that it definitely does.
Then again, there’s also evidence that the compounds in cannabis have, in some instances,
been shown to kill certain types of cancer cells, including those found in breast, lung,
prostate, and skin cancer.
Again, we must reiterate that there have been some very positive results, but only with
some people, so we definitely can’t say cannabis, mainly CBD, will help someone beat
cancer.
One thing it seems to do for scores of people is help with their cancer pain, which is why
more and more countries have given it the green light to be used in limited medical
instaces.
On the other hand, you also have the genotoxic effects of oxidized hydrocarbons that occur
when you burn cannabis, which has been said to create genetic changes that could potentially
lead to a carcinogenic state.
A paper published by the National Institutes of Health said weed joints “deliver at least
four times as much tar to the lungs as tobacco cigarettes of equivalent weight,” explaining
that it’s because, in these joints, there are not usually any filters and people tend
to hold weed smoke in longer.
In short, when you compare weed smokers or cigarette smokers with non-smokers, the incidence
of respiratory problems is much higher; one study showed it was one in three compared
to one in twelve, but we still can’t say for sure if cannabis causes cancer.
In one study, a big one, out of 65,000 people, it seemed marijuana use might have had a negative
effect on prostate cancer but not any of the many other cancers.
The participants were aged 15 to 49 only, so more studies looking at older people would
have to be done since cancer is more common in older folks.
We are not going to tell you that regularly smoking weed doesn’t cause cancer, but we
are also not going to tell you it definitely can.
What we will say is your month on weed is certainly not the riskiest thing you’ll
ever do in your life.
But you are inhaling smoke, and while it might not be as carcinogenic as some news articles
might suggest, it’s very possible that this experience is damaging your lungs.
As things stand, with you now having smoked weed daily for three weeks, we don’t think
there will be any substantial damage.
If you smoked joints every day for years, well, your lungs will suffer.
Just how much, we just can’t say.
It gets even more confusing when you read about vaping weed.
Vaporizer devices activate cannabinoids, but they don’t heat the goodness to the point
of combustion.
You might read this and think, great, the vape it is then, but then you read vaping
articles such as this one from Johns Hopkins Medicine:
“Emerging data suggests links to chronic lung disease and asthma, as well as associations
between dual use of e-cigarettes and smoking with cardiovascular disease.”
But that same article also said we still don’t have a definitive answer as to how bad vaping
is for your body.
We do know that when you do vape, you also inhale harmful chemicals, and some doctors
in the US have said they’ve seen more and more people coming to see them with conditions
that could very well be related to their vaping habit.
You all probably know former smokers who now vape, and they look like steam trains most
of the day.
Still, no one vapes weed in such high quantities.
You’ve now been smoking weed daily for almost the full month.
Will it be hard to quit?
Is weed addictive?
Yet again, this question is not easy to answer.
Not all substance addictions and withdrawals are the same.
If you have a physical addiction to alcohol or benzodiazepines (Valium, etc), coming right
off after a long time can actually be very dangerous.
You might not only have seizures that can and do kill, but in terms of mental well-being,
you might think you’ve been plunged into anxiety hell, and we do mean hell.
This is related to the effect these drugs have on your GABA receptors.
In layman's terms, if a substance makes you very relaxed, your brain might stop creating
chemicals that usually make you chilled, so when you stop, the very opposite of being
relaxed happens to you.
It’s the same for people who stop taking opiates and become incredibly restless and
depressed.
But what about weed?
Does that kick the poop out of you when your body no longer has it?
Actually, with cannabis withdrawal, you are definitely not going to experience anything
like we just mentioned.
But there is something called marijuana use disorder.
People have been known to become dependent on weed.
Their body craves the physiological changes that weed has been giving them.
They can develop a tolerance, so they need more and more.
Still, it’s said only 10 to 20% of daily weed users will develop a dependence.
There will be some mild withdrawal symptoms when they stop, maybe lasting around two weeks.
These might include cravings, irritability, decreased appetite, mood and sleep difficulties,
restlessness, and other kinds of physical discomfort.
A paper in the National Institute of Drug Abuse in the US stated, “In 2015, about
4.0 million people in the United States met the diagnostic criteria for a marijuana use
disorder; 138,000 voluntarily sought treatment for their marijuana use.”
With any psychoactive substance, there’s no clear line you can cross as to how long
and how much you can actually consume before developing a dependency.
Everyone is different.
There are cases of people smoking weed for years and having zero problems stopping, or
maybe just mild issues.
Then you have people who’ve smoked for shorter periods of time who feel pretty bad after
stopping.
But on the whole, in terms of withdrawal symptoms, weed is far, far less dangerous than many
substances we use to change the way we feel.
Weed withdrawal is a gazillion times safer than if you were a regular consumer of things
such as Xanax, Percocet, or Johnny Walker.
Still, you should be aware that becoming dependent on weed is possible – studies show that
this is a disproportionately bigger problem for younger people.
Ok, so your one month is up.
To be honest, since you’ve taken your weed sensibly, you feel fine.
You are aware of all the psychological dangers some people face with weed consumption, but
it seems, for now, you are not one of those people who react badly to it.
That said, if you keep this up, there is a very real possibility you’ll damage your
lungs, and there’s also a possibility you’ll develop a dependence.
Still, since you feel better, are sleeping well, have less social anxiety, and your work
hasn’t been negatively affected, you think you’ll carry on, although just to be safe,
you’re going to limit your smoking to small doses just a few times a week.
Many people don’t even know why they smoke weed.
They might tell you, “The reasons?
There are no reasons.
Who needs reasons when you've got weed?”
One person interviewed in The Guardian felt that way for 40+ years.
She got to the point that she didn’t even know if she enjoyed it anymore.
She said in the interview, “I smoked to go to work, smoked to do the washing-up, smoked
for chill time.”
In the end, she said her lungs started to hurt, and her gums regularly bled.
She didn’t know why she wanted it, but she craved it when she didn’t have it.
One day, she realized she’d gone two days without weed and then just thought, ok, enough
is enough.
She craved it for sure, but with the help of meetings and counseling, she stopped completely.
And guess what?
She started dreaming again.
That’s something you noticed when you smoked for a month.
You didn’t dream.
Many people don't regularly smoke weed because it interrupts the amount of time people spend
in rapid eye movement (REM) sleep - when most people dream.
Dreaming was one of the big changes for her, but everyone is different where cannabis withdrawal
is concerned.
These are some comments made by people who quit after many years of daily smoking:
“I just quit after 10 [years] as well... just cold turkey it, no withdrawal symptoms.”
“The withdrawals have not been fun, I’ve lost 4 lbs. in two days because it’s really
hard to eat.
Mentally, I feel really clear and happy.”
“My boyfriend stopped smoking weed like 2/3 months ago, and I am noticing that his
behavior is different.
He is more angry and not as sweet as he used to be.”
And this one: “I quit after about six years of smoking
every day.
It made me anxious and awkward in social situations.
I would overanalyze things and think really weird/delusional thoughts.
Forget about talking to girls.
I couldn’t handle it.
Since I quit, all these things went away.”
As it said on the walls of the Temple of Apollo in ancient Greece, “Know thyself.”
With weed, you have to educate yourself and assess if it is good for your mental health
while adding up the pros and cons as to how it will affect your body and life in general.
If you absolutely want to experience weed, we suggest wading in slowly rather than diving
straight into the deep.
It can be a mysterious ocean out there, and you never know what you might find.
As we've told you many times today, scientists haven’t yet plumbed all the depths of Mary
Jane, not entirely.
