I’m sorry that your mental health is in such a bad state.

I read in your other comment that you’ve been a daily cannabis user for decades, and now I can understand your aggressive defense of the drug, and your unhinged behaviour.

I wish you said that sooner. Your agenda is to defend your addiction, so there was never an honest discussion here.

It was fun. Get some help.

You are being down voted but this exact thing happened to somebody I know. The repeal of criminalization, without a better education plan, gave them the idea that “Oh its fine now”. They became addicted to smoking it, spent all day every day just hitting a bong. Stopped working, had to repeat a year at uni to get courses on track. They’ve had to completely abstain, or they fall back into the spiral. Some people get addicted to alcohol, some its another drug entirely.

Have you had psychosis from a beer every day? Notice I’m not saying they are the same, but all drugs can do damage if overused. Heroine has no side affects after it wears off, but will end you with slightly too much. If I over drink caffeine my blood pressure skyrockets and I’m a candidate for something bursting and dying of an internal bleed. For me coffee is dangerous.

You’re not sorry for shit, you’re just upset that you got caught deliberately misrepresenting the contents of those studies, and now you’re looking to do the same thing about me personally because you don’t have to a leg to stand on and you know it. Nobody ever calls daily coffee drinkers addicts, it’s psychoactive and far easier to die from. Your bullshit is painfully obvious and nobody is buying it. Get a job.

Nobody who isn’t already hereditarily predisposed to psychosis has ever developed psychosis from cannabis consumption. Nobody has ever required an organ transplant due to cannabis consumption either. Heroine absolutely does have long-term negative effects, marijuana has none outside of respiratory effects which can be completely avoided with any other method of ingestion. Quit lying.

I’m being downvoted because addicts have to defend and justify their addiction, unfortunately.

I had a family member who also went through the same. They developed psychosis (Cannabis-induced depersonalization-derealization disorder) through daily use of cannabis, and ended up needing to get treatment after their life went downhill.

Stopped once the weed stopped, but it was an alarming transition, and not an easy addiction to break.

They only became hooked once legalization came into effect, since it was accessible from anywhere.

Some bold claims. The life style around heroine addiction has negative affects, but per experts it is a connector that is done when it pops off. Out of the entire world drinking responsibly how many organ transplants are there? Its those who overuse that are an issue. The drunk driver is no different than my high neighbour that smashed through a gate, that gate could have easily been a person. I don’t claim marijuana is horrible but the best argument people who use marijuana come up with is " well it’s not alcohol, alcohol is worse". That whataboutism is dangerous when people think that equates to over indulgence is without risk.

you’re just upset that you got caught deliberately misrepresenting the contents of those studies

I’m not upset about anything. The studies speak for themselves.

and now you’re looking to do the same thing about me personally because you don’t have to a leg to stand on and you know it.

No, that extra bit of information gives me context for understanding where you’re coming from.

You were never going to be receptive of the facts, because they’d contradict the story you’ve been telling yourself about the “safest” harmful recreational drug.

I just never realized that was your motivation until just now.

Nobody ever calls daily coffee drinkers addicts

Who’s arguing about coffee, anyway?

As cannabis use among youth rises in Canada — and THC potency reaches record highs — emergency departments are seeing a surge in cases of a once-rare condition: cannabis hyperemesis syndrome (CHS).

Characterized by relentless vomiting, abdominal pain and temporary relief through compulsive hot showers or baths, CHS is increasingly affecting adolescents and young adults. Yet few people — including many clinicians — know it exists.

Canada ranks among the highest globally for youth cannabis use, with 43 per cent of 16-19-year-olds reporting use in the past year. Usage peaks among those 20–24 years, with nearly half (48 per cent) reporting past-year use.

This rise in regular, heavy use coincides with a 400 per cent increase in THC potency since the 1980s. Strains with THC levels above 25 per cent are now common. As cannabis becomes more potent and accessible, clinicians are seeing more cases of CHS, a condition virtually unheard of before 2004.

CHS unfolds in three phases:

1. Prodromal phase: Nausea and early morning discomfort begin. Users increase cannabis consumption, thinking it will relieve symptoms.

2. Hyperemetic phase: Intense vomiting, dehydration and abdominal pain follow. Hot showers or baths provide temporary relief — a hallmark of CHS.

3. Recovery phase: Symptoms resolve after stopping cannabis entirely.

Diagnosis is often delayed. One reason is because CHS mimics conditions like gastroenteritis or eating disorders, leading to costly CT scans, MRIs and gastric emptying tests. One telltale sign — compulsive hot bathing — is frequently overlooked, despite its strong diagnostic value.

Youth face unique risks. The brain continues to develop until about age 25, and THC exposure during this critical window can impair cognitive functions like memory, learning and emotional regulation. Heavy cannabis use is associated with heightened risks of anxiety, depression, psychosis and self-harm.

Just a moment...

Results There were 12 866 ED visits for CHS from 8140 individuals during the study. Overall, the mean (SD) age was 27.4 (10.5) years, with 2834 individuals (34.8%) aged 19 to 24 years, 4163 (51.5%) females, and 1353 individuals (16.6%) with a mental health ED visit or hospitalization in the 2 years before their first CHS ED visit. Nearly 10% of visits (1135 visits [8.8%]) led to hospital admissions. Monthly rates of CHS ED visits increased 13-fold during the 7.5-year study period, from 0.26 visits per 100 000 population in January 2014 to 3.43 visits per 100 000 population in June 2021. Legalization was not associated with an immediate or gradual change in rates of ED visits for CHS; however, commercialization during the COVID-19 pandemic period was associated with an immediate increase in rates of CHS ED visits (incidence rate ratio [IRR], 1.49; 95% CI, 1.31-1.70). During commercialization, rates of CHS ED visits increased more in women (IRR, 1.49; 95% CI, 1.16-1.92) and individuals older than the legal age of cannabis purchase (eg, age 19-24 years: IRR, 1.60; 95% CI, 1.19-2.16) than men (IRR, 1.08; 95% CI, 0.85-1.37) and individuals younger than the legal age of purchase (IRR, 0.78; 95% CI, 0.42-1.45).

You’re being downvoted for pushing verifiably false drug war talking points, lying about the contents of the studies you linked, and accusing everyone who points any of that out/proves you wrong of being addicts. You’re a mess bud, seek professional help.

You lost, the only honest response from here is for you to admit it and move on like an adult

This feels like playing chess with a pigeon, TBH.

Ok, buddy. “You win.”

I’ve already corrected your misinterpretation of the studies on several occasions, so there’s no need to continue to belabour the point. If you want to argue about it to the authors of those studies, I’m sure they’d love to hear from you.

This is not a “war on drugs”, but a public health concern. You’re free to harm yourself however you like. But the public, especially our youth, should be better informed of the risks, especially while the chatter about cannabis being “safe” is still being thrown about casually.

What experts? Because it took me all of five minutes to find a shitload of resources detailing long-term permanent effects of heroin abuse including brain damage, feel free to try finding even one credible source that says otherwise

We’re not discussing responsible alcohol usage, per your previous comment we’re talking about abuse. Abuse of alcohol can easily kill a person in a single drinking session, not true at all for any form of cannabis no matter how concentrated. Alcohol abuse can destroy your organs in just a few years requiring transplant to avoid an agonizing death, also not true for any form of cannabis no matter how concentrated even after a lifetime of heavy use. And yes, alcohol actually is still harmful even in small amounts, it’s a fucking carcinogen, it directly results in cumulative cell damage leading inevitably to cancer, there is literally no safe amount. If you drink and don’t get cancer it’s only because you managed to get killed by something else first.

What are the long-term effects of heroin use? | National Institute on Drug Abuse

Repeated heroin use changes the physical structure13 and physiology of the brain, creating long-term imbalances in neuronal and hormonal systems that are not easily reversed.14,15 Studies have shown some deterioration of the brain’s white matter due to heroin use, which may affect decision-making abilities, the ability to regulate behavior, and responses to stressful situations.16-18 Heroin also produces profound degrees of tolerance and physical dependence.

New genetic study confirms that alcohol is a direct cause of cancer

(www.ndph.ox.ac.uk)

And cannabis? Minor risk of cancer due to smoke inhalation in traditional ingestion, none for any other method of consumption

https://pmc.ncbi.nlm.nih.gov/articles/PMC1277837/ “It should be noted that with the development of vaporizers, that use the respiratory route for the delivery of carcinogen-free cannabis vapors, the carcinogenic potential of smoked cannabis has been largely eliminated”

https://pmc.ncbi.nlm.nih.gov/articles/PMC4302404/ “…a null association between marijuana use and lung cancer is somewhat surprising since marijuana smoke contains known carcinogens in amounts comparable to those found in tobacco smoke (49). While the generally smaller amounts of marijuana that are regularly smoked compared to tobacco might appear to explain the null association of marijuana with lung cancer, the absence of a dose-response relationship between marijuana use and lung cancer, in contrast to the strong dose-response relationship noted for tobacco (16), would argue against this explanation. A more likely explanation is a tumor-suppressant effect of THC and other cannabinoids evident in both cell culture systems and animal models of a variety of cancers, as reviewed by Bifulco et al. (57). These anti-tumoral effects (anti-mitogenic, pro-apoptotic and anti-angiogenetic) could possibly counteract the tumor-initiating or tumor-promoting effects of the carcinogens within the smoke of cannabis.”

So even in the most harmful method of cannabis consumption there are verifiable anti-carcinogenic effects mitigating the carcinogenic effects of the smoke! And again, literally any other method of cannabis ingestion completely bypasses all carcinogenic effects and respiratory damage, leaving zero long-term health effects.

Your allegedly high neighbor who allegedly smashed your gate does nothing to change the verifiable fact that cannabis is infinitely safer than any other recreational substance in existence, correcting you on your nonsense isn’t “whataboutism” you’re just upset at being corrected.

The Conversation (theconversation.com)

Why is everyone so combative as if this has not been well known for decades?

Cannabis is a drug just like every other. It’s not safe unregulated. This is evidence that we should regulate and provide safe guidelines on usage.

But I know so many people that spread that you can’t eat or smoke to much cannabis. That level of ignorance is no better.

A lot of assumption/projection there dude. I am by no means upset.

I wouldn’t say “combative”. Critical, maybe.

It is a syndrome they’re describing, with rather vague symptoms and a very large userbase.

I’m not one to deny the risks of anything, but since cannabis has been subjected to biased research and journalism for 100 years, it’s not really surprising some people are somewhat critical of something this vague.

Like what’s your suggestion on “regulation”? Because I think an appropriate age limit is fine, just like with alcohol. Actual proper legalisation would allow people to actually know how much theyre consuming. Now it’s just random strength weed for random amount of inhale. If you knew x mg per puff or edible, like you can do in some places, but not most of the world, then it becomes easier knowing how much you’re actually consuming. So yeah, better regulation. Which requires legalisation.

A lot of verifiable scientific evidence that I’m right, the fact that you’ve completely ignored all of it and failed entirely to admit that you were wrong indicates pretty strongly that I’m also right about your emotional state as well
