Disclaimer: I'm an almost daily smoker of cannabis. There is definitely some impairment long term. I think we can assume that even without this huge study. I don't think knowing that matters unless we have some scale that tells us how dramatic that impairment is. If I compare someone who smoked all the time, but also had a rich and engaging social life with a lifelong abstainer who live a mostly isolated existence, w…

Oh goodness. Thank you for introducing me to Shadow Wolves. It sounds positively dreadful. I want to read it but I don't want to pay for it. Either monetarily or cognitively.

You really really don't though. It's not one of those 'so bad it's good' kind of things where there is some novelty to be had. It's boring. It's written with a 4th grade vocabulary. There's no character development outside shallow tropes. Random right wing conspiracies are mixed in without any grounding in the story. The main character is a cartoon of cartoon of a human in a cartoon world with cartoon side kicks. It's awful in every way a book can be awful. And to top it all off it will literally curse your brain.

I’m not sure why you’re asking if I missed that part given it was me that shared the anecdote to begin with.

Because that doesn't seem to be factoring into your analysis of the source of the impairment. If I told a story about a kid who showed back up at band camp and had become 50 pounds heavier and hadn't progressed as a drummer, then went on to become a heroin addict etc. you wouldn't be blaming cookies. You'd stop and wonder what the hell was going on in his life.

I wasn't aware that cookies cause paranoid delusions.

Marijuana on the other hand…[0]

As I mentioned, I grew up with several kids like this. Most didn't attempt suicide (as far as I'm aware, anyway), but the possibility of confirmation bias aside, I certainly feel as though I recognised a pattern of paranoid delusion among young stoners that I knew.

I grew up in a super poor neighborhood, and I knew maybe 10-15 kids who started smoking MJ before age 16. The only ones who had any kind of extreme cognitive fallout were the ones that dabbled in more extreme stuff (like PCP). Even in those cases though, it's hard to point at the drug as opposed to the reason they were using. (In the PCP case it was three brother with a mentally ill single mother)

I'm not discounting the possibility that MJ can cause such things, but even the studies put the risk fairly low, and it's hard to separate environmental and genetic risks in the population they have available to study.

I'm not sure exactly what OP means, but depersonalization disorders are PTSD symptoms, often linked to trauma, and can be induced from cannabis[1]. My personal opinion is that legal states are making a mistake at treating concentrates (and edibles to a degree) as being as benign as their flower counterparts. 1. https://psychiatryonline.org/doi/full/10.1176/appi.ajp-rj.20...

I've had depersonalization for over 10 years now after an incredibly intense experience from the first time I smoked weed(age 16.) Looking back I was a very anxious/depressed kid but theres no argument weed affected me in a very damaging and permanent manner. I'm sure I would have been far more successful in life had I not smoked at all, but at the same time, I'm guessing I would have been much more narcissistic and…

There is ample research that cannabis functions as an anti-depressant. https://scholar.google.com/scholar?q=cannabis+as+antidepress... There are many caveats that go into posting a Google Scholar link - the quality of the research is unknown, there is the reproducibility crisis to worry about, etc. etc; However, the presence of this ample research means that "Cannabis isn't actually an anti-depressant" is far from se…

Most of those top links are for cannabidiol, not cannabis. One of the top results clearly says that scant research suggesting that cannabis is an antidepressant is lacking in quality. Your link doesn’t even begin to support your claims.

Literally first title:

"Antidepressant-like effect of Δ9-tetrahydrocannabinol and other cannabinoids isolated from Cannabis sativa L."

And yes, the majority of the claims are that CBD is the anti-depressant; self-administration of CBD comes primarily from smoking/vaping/ingesting cannabis, so I don't even understand what "cannabidiol, not cannabis" means.

I don't really get the impression that you are arguing in good faith here, especially the "Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize." part of HN guidelines, so I'm just gonna drop this thread now.

This is an interesting story, but you have to wonder what led to this kid starting to smoke weed in the first place. It sounds to me like he may have had bigger underlying mental health issues that caused him to start smoking, rather than the weed being the cause of his subsequent suïcideer attempt and heroin addiction.

And what if the weed took his minor problem and significantly magnified it? We see this behavior happen all the time in other drugs like SSRIs.

That's how I feel when using. The good times become better, but the bad times become worse.

Before anyone freaks out too much: "Persistent" means up to one week. From the actual paper: "However, results were not significant for an abstinence period of more than 7 days." Basically, science has proved that stoners behave like stoners. And if you stop it takes a few days for everything to wear off.

This matches my experience perfectly. I used to smoke weed about once a month when when I was a teenager, and I noticed that I could observe mild cognitive impairments for about a week after smoking. They were fading gradually during those days. To illustrate, the next day after smoking I would occasionally notice that it takes me two times longer than usual to understand the task in school textbook and sometimes I c…

Your experience pretty much matched mine with the cognitive impairment. It’s just something to wait out and not get stressed about for 2-3 days after.

I find I get a bit paranoid when I take too much (generally I only ingest edibles, my days of harsh af smoking doobies are over).

However, I do see benefits because I’m the kind of person that let’s little stressors accumulate over time. My somewhat infrequent usage has always come with a reset of my stress. It would be nice if it didn’t also come with a bit of downtime the week after.

As a user, I highly recommend that anyone under 21 not use cannabis. Their young brain is still developing. It’s a drug like alcohol. Addiction can have consequences.

Agreed. I started my drug usage in my mid-20s (including alcohol) and I highly recommend it. My brain was done cooking and I had enough self-confidence + self-awareness to not make dangerous decisions.

Same here! Both for alcohol and weed. Based on the little I know, that seems to be much better than starting to smoke while the brain is developing.

Haha. Fair. I've got this morbid curiosity about right wing authoritarian conspiracy fiction. Apparently Ben Shapiro has several novels in the same vein. Genuinely curious... why'd you read it in the first place? Are you part of the worst book club in history or something?
