Psychosis rates climb among young people in Ontario, researchers find
-
People aged 14 to 20 are more often being diagnosed with psychotic disorders, including schizophrenia, compared with those born earlier, a large Ontario study examining 30 years of data suggests.
To conduct the study, published in Monday’s issue of the Canadian Medical Association Journal (CMAJ), researchers looked at health administrative data from more than 12 million Ontario residents born between 1960 and 2009 to look for cases of a psychotic disorder.
In the Ontario study, those diagnosed with psychotic disorders not linked to mood disorders, such as schizophrenia, were more likely to be male, live in low-income neighbourhoods, be a long-standing resident of Canada and have received care for mental health disorders and substance use.
Why isn’t known. Myran and his co-authors suggest several possible reasons for the increases: older parental age, socioeconomic- and migration-associated stress and an increase in some negative childhood experiences like abuse in more recent decades.
Myran said there likely isn’t a single explanation, but he called substance use — including cannabis, stimulants, hallucinogens and synthetic drugs — a leading possibility contributing to the rising rates over 20 years.
I watched a kid (at least 17 or 18, but possibly 19) get turned away from the weed store the other day. Ya know what I never had a hard time with as a teenager living in a pre-legalization era? Buying weed!!! If you asked me today where I would go to get weed that isn’t a legal dispensary that IDs minors, I wouldn’t know where to go.
Do you think it’s easier for 14-19 year olds to get weed now than it was 10-11 years ago? I really don’t.
I cannot believe that these numbers are rising due to cannabis consumption, that seems like a really unlikely probability, to me at least?
Synthetic drugs have been making people fall into dangerous psychoses for almost the entire time synthetic cannabis has been sold to humans. -

It’s fine in moderation but I know most teens aren’t super hot on moderation. There are also loads of these Delta-8 and other cannabinoid concentrate vapes sold cheap online and who knows what’s in those things.

How about all the microplastics and other chemicals in our environment that are now sitting inside of us doing god knows what, like maybe acting as a mutagen fucking up our gamete DNA. Mutagens cause mutations to gametes. So you can have a normal mother that is exposed to mutagens over time, the DNA in their eggs get mutations, and the DNA in the fucked up gamete get passed on to the offspring. So now you have an offspring that has a genetic propensity to develop a psychosis based disorder. Stimulant use absolutely can cause psychosis, as well as extended use of hallucinogens. Usually in weed caused psychosis, it’s an acute episode that clears once the drug is out of your body in a few hours to days. OP do you have a link to the full study? I’m wondering if their modeling and data sets allowed them to control for people that actually used stimulants vs no stimulants. This would require something like a 2 way anova where you factor drug use and age.

The dude was on CBC this morning, saying that youth’s initial psychotic episodes correlate heavily with cannabis use.
Without seeing the actual study, I reserve the right to think that this “scientist” published bullshit data and is full of bias.

I hit the same vapes, legal and black market, and my biggest concern would be toxic metal poisoning from sucking on low quality vape carts over excessive cannabinoids uptake.

Is there a link missing for this or am I blind?

You’re right. I just dunno how someone can post without a link attached. Weird.

Fixed, sorry about that

Me too. My DNA250 is on its way out and there’s none left in Canada (that I can find anyway). Plus American prices for them are crazy rn.

Maybe we could make a community for crowd sourcing a solution.

Yeah that’s a definite concern too, or adulteration with a cheaper product ie synthetic cannabinoids. I guess it all comes down to making sure you’re getting things from verified and trusted manufacturers as with any consumer product.

Synthetic drugs have been making people fall into dangerous psychoses for almost the entire time synthetic cannabis has been sold to humans.High THC weed, instead of balanced. We know a few people hospitalized because of weed psychosis

The study does not take drug use into account, although it says it does, none of those results are published in the study or the supplemental index materials. This study is not well done, and as someone with a PhD in neuroscience, I would have given it a thumbs down if I had gotten to peer review it based on how drugs are talked about in the study vs no published results on that topic. One positive thing I will say is that Canada’s single payer system makes for a large population to conduct studies, and the findings indicating that people are being diagnosed earlier are crystal clear. What they don’t talk about is the rate at which people seek out medical help for mental health issues. One confounding thing about culture is that availing oneself of psychological help was often viewed as shameful or as a weakness among the boomer and older generations, it’s likely that fewer boomers sought out help or possibly waited until they were older with more sever symptoms before getting help and a diagnosis. It’s a complex issue with lots of confounding factors.

Thank you!

Synthetic drugs have been making people fall into dangerous psychoses for almost the entire time synthetic cannabis has been sold to humans.I don’t have it handy but I remember seeing research years ago that pointed out the link between cannabis use and schizophrenia especially in males under 20, but wasn’t able to identify whether it was causation or whether the patients were self medicating with cannabis.

I think vape shops just stopped ordering them because all the tanks they use are illegal.
Why bring in mods when you are out of RTAs or RTDs?
