Why more youth are landing in the ER with vomiting from cannabis use
-
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:
-
Prodromal phase: Nausea and early morning discomfort begin. Users increase cannabis consumption, thinking it will relieve symptoms.
-
Hyperemetic phase: Intense vomiting, dehydration and abdominal pain follow. Hot showers or baths provide temporary relief — a hallmark of CHS.
-
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.
Edit, the link in the article goes to this study:
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).

The Conversation (theconversation.com)
This is just the symptom of a much bigger underlying issue. We can talk about regulation all we want or even banning it, but it won’t solve the big problem of what young adults have to face today in society at large. They are ill prepared for the real world, bombarded by social media influences 24/7, this is just another coping mechanism they’ve turned to.
Excessive use of alcohol, vapes, sugar etc. are all just as bad. But hey, the stats are saying 16-19 year olds at 43 percent - last I checked the legal age to purchase cannabis was 19 in Canada. So, anything under that would be considered illegal and I’d solely place the blame on the parents - just like any other substance abuse. Alas, that still doesn’t solve the mental pressures that these young adults will need to face (housing, employment opportunities, global factors - climate change etc.). We can educate all that we can, but it won’t change the reality. The reality is that it takes real political will and a strong mandate from voters (we all know our federal government is like a bunch of companies in a trench coat and that needs to change) to actually FIX the money side of problems. I am not surprised that the 20-24 year old’s use cannabis (48% claimed by the article) - record inflation anyone? high groceries? lack of good livable wage employment? housing?
Here’s my hot take, cannabis gets more bad rep than alcohol when alcohol, IMO, is worse.

I like how “used it in the past year” in one paragraph mysteriously becomes “regular, heavy use” in the next.

I don’t buy this “increased potency” argument as it sounds like the same anti-weed shit they’ve been saying since the 90s. We had concentrates and hash and vaporizers in the 2000s. Potency of the flower doesn’t matter much when you can rip volcano vapes from dawn till dusk. All these “CHS” stories also always mention the dumb “hurr Cannabis psychosis” shit which is the other Hallmark of old anti weed propaganda that makes me skeptical.
Idk, it kind of feels like hysteria or some related comorbidity with munchies. I’ve definitely known people who make themselves sick over and over again from eating too many Doritos

Before legalization, pretty much every cannabis magazine and website was being cited as saying it was totally safe. Even mocked people for thinking otherwise.
That changed public opinion, and experts were ignored. These risks were known many years ago, so why has the industry been allowed to keep selling stronger strains, marketing to young people, and making these drugs available everywhere?
Now that the consequences are being seen, what are we going to do about it? This shit is being sold at every street corner, sometimes multiple cannabis shops at the same intersection. It’s nuts.
One could argue it is safe in reasonable moderation. CHS devlops due to extreme and excessive daily use of cannabis. Enjoying a joint every now and then is far safer than toking every 30 minutes.
If i ate 30 chocolate bars everyday for weeks on end, I’d have some serious health issues, but one every weekend would be nearly unnoticeable from a health perspective.
-
Only marketing I’ve seen is anti-drug ads
And per the above article, drinking until you puke seems to be worse
Only marketing I’ve seen is anti-drug ads
Recently, or around the time of legalization? Even pulling up Google Maps will highlight the cannabis shops, which is an insidious way to promote them.

The problem is, what Health Canada once labelled as “heavy use” is pretty much normal use these days. Daily use, or using multiple times a day, is very common.
If people (and teens) were only consuming once in a while, I doubt we’d be in this mess.
They consume often, partly because they’ve been told “it helps with XYZ”, so they self-medicate, which leads to greater problems. But also because they believe it’s “safe”.
Single cannabis use can also lead to acute impairment and puts stresses on the body. I’ve never heard of someone getting in a car and killing someone because they were impaired on having chocolate that afternoon.

You’re lucky, I guess. Even just driving/riding around, I see cannabis shop signs everywhere. And I don’t want to see them, so I can only imagine how they stick out to an addict or vulnerable person.

Alcoholic here. Booze at every restaurant, at every corner store, empty cans in the ditch, at every sporting event, liquor stores everywhere, every adult gathering I go to and most family ones too has booze, concerts, music venues even the movies have booze now. It need to all go. I don’t want to see it. I also don’t want to see maple magats, huge diesel trucks idling with no one in them, indigenous people being arrested,killed and harassed for existing, churches…I hate fucking churches…every single one needs to go. Google maps also has all those places. They’re promoting hatred and alcoholism.
You sound like a child.

I smoked dope and hash like a fiend when I was a kid, I never experienced or even heard of this.
Though I did get the munchies.
-
-
When I was a kid it was alcohol poisoning and lots of kids even in my rural community died in ditches and at bush parties. There were 300 kids in my high school. Grades 9-12. We had 6 deaths from alcohol. Either consumption or drunk driving. I’d be interested to know how many kids are dying from cannabis ingestion or accidents related to.
Gonna be really close to zero.

I’ve worked in a parc, we were not security but prevention guy that walk the parc talking to teen getting high, and kids were always saying « the weed now is way more potent that it your time ». Bullshit !

I’m a long time daily user as well, and my suspicion would be the ever increasing potency. I have a quite high tolerance, yet a high THC strain (iirc advertised were 26-27%) i bought some months ago seriously fucked me up.
Loss of motor control, balance, intense nausea and sweating, I had to literally sit on the toilet and lean my head and upper body against the wall for 45 minutes, because that was somehow the only bearable position with the option to puke if needed. Topped off with a racing mind going to unhappy places.
I then sort of cut the stuff with “normal” ~20% weed to tone it down and make it tolerable. I can definitely see these potent strains having unexpected and perhaps so far undocumented effects on the body. A little like beer versus liquor.

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).
Why more youth are landing in the ER with vomiting from cannabis use
Cannabis hyperemesis syndrome — with severe vomiting, abdominal pain and temporary relief through compulsive hot bathing — is increasingly affecting adolescents and young adults.

I am an old fellow who has been using cannabis almost daily since 1966. I have never heard of these symptoms. I hang out with many other old people with similar profiles. I have asked around nobody has heard of these symptoms. This article reads like bad AI.

Alcoholic here. Booze at every restaurant, at every corner store, empty cans in the ditch, at every sporting event, liquor stores everywhere, every adult gathering I go to and most family ones too has booze, concerts, music venues even the movies have booze now. It need to all go. I don’t want to see it. I also don’t want to see maple magats, huge diesel trucks idling with no one in them, indigenous people being arrested,killed and harassed for existing, churches…I hate fucking churches…every single one needs to go. Google maps also has all those places. They’re promoting hatred and alcoholism.
You sound like a child.
It need to all go.
Sounds like we agree.
I also don’t want to see maple magats, huge diesel trucks idling with no one in them, indigenous people being arrested,killed and harassed for existing, churches…I hate fucking churches…every single one needs to go.
Not sure what any of that has to do with drugs harming kids, but OK.
Google maps also has all those places. They’re promoting hatred and alcoholism.
They are. We agree on that, too.
You sound like a child.
OK. We seem to be agreeing on the same things, so… I guess you sound like a child, too?
I have concerns about drugs influencing our most vulnerable, and the external pressures that make it difficult for them to avoid it.
As an alcoholic, one would think you’d agree that it’s a problem.
Not sure what your personal beef with me is, though.

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:
-
Prodromal phase: Nausea and early morning discomfort begin. Users increase cannabis consumption, thinking it will relieve symptoms.
-
Hyperemetic phase: Intense vomiting, dehydration and abdominal pain follow. Hot showers or baths provide temporary relief — a hallmark of CHS.
-
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.

I’ve read a little about it once in a while. Apparently one of the ways to treat this is to administer haloperidol, an antipsychotic, to relieve the symptoms. It’s not a very long lasting condition either, especially if the user can recognize that weed’s causing it and just stops for a little while.

It’s real, a person I know went through it. They basically just smoked a bong all day, every day. Creates a paralysis like effect on your intestines.

Heavy cannabis use is associated with heightened risks of anxiety, depression, psychosis and self-harm.
So is antidepressant use.
That’s correlation though. The reason you get prescribed antidepressants is a bias pick for already being a risk to self.
