I wonder about all the confounding effects. In my country (famous for cannabis to be easy to come by (for decades already), and I saw many smoke from age 16 up as I grew up in 90's, 00's). I have always felt that the heavy cannabis smokers had something to compensate; stress, unrest, impending depression, friction with parents. It was never the healthy sporty types with fulfilling relationships, good grades or a nice career that smoke cannabis heavily (like daily). Sure, some of those smoked, but more occasionally.

I’m not from a place where cannabis use was common, but it was present.

Growing up I definitely knew some people who had their demons who turned to drugs.

However we also had a lot of people who were in good situations who picked up drugs for purely recreational reasons. One of my friends at the time even boasted that drugs were actually more appropriate for people like him who were educated, in good situations, and rational (his description of himself) because they knew how to manage themselves and their usage better. He even had links to some subset of the rationality community who had become pro-recreational drugs with a lot of justifications.

His turn to drug use marked the end of his promising academic career. He started struggling with mental health in ways that were obviously related to the drugs. Holding a job had never been a problem until he starting smoking, which marked his turn toward job struggles. His friends and family relationships started declining and falling apart.

He’s not the only one I know like this. The first person I knew who had to go to rehab for drug addiction was a happy, successful guy who started using drugs as a way to party more and for longer. He thought his life was awesome and he was invincible.

I think there’s become a belief that drug use is purely a symptom, but I’ve seen enough people go from happy to falling apart as an obvious result of the drug use. Most of the people I know who started using drugs didn’t do it at their homes in private to cope, they started doing it at parties with friends.

This is even well known with alcohol: There is common belief that being a “social drinker” is a different risk profile than someone who does their drinking alone.

I think it’s a comforting idea that we tell ourselves that nobody chooses to use drugs, they are driven to do so by circumstances out their control. We like removing blame from people and hoisting it on to the world. I don’t think it’s always true, though. Many people use drugs because drugs are rewarding (at first) and they like the way the drugs make them feel. The negative consequences come later.

I have largely stopped smoking because when I smoke regularly I end up weighing 20-30lbs more from eating everything.

Going on an actual calorie restricted diet while consuming cannabis is basically impossible for me.

Then instead of walking 60 minutes I end up sitting and listening to music.

There is really not anything for me that correlates with healthy behavior when I smoke.

this is true of most risk factors though, diet, excercise, relationships, work , all suffer under stress. it's the job of medical reseach to sift this stuff as best they can.

> stress, unrest, impending depression, friction with parents

Well, Id guess these are reasons for any case of substance missuse?

Definitely. The healthy sport academic types stay pretty far away from any kind of mind altering drugs.

Yeah I think for any of the significant pot smokers I've known it's a way of avoiding other issues. As a positive it's probably much better they descend into pot than alcohol which I'm sure many would if it was the only other easy coping mechanism.

In my country, California, we have so much cannabis use and it’s by basically everyone. People with spouse and children, fulfilling careers and exercise regimes. The culture of a place really can change the outcomes. It’s part of why Silicon Valley beat Route 128.

In American collegiate and professional athletic circles almost everyone uses marijuana. I was a nationally ranked junior tennis player and even in that sport almost every other top junior I knew smoked weed.

^^ many of those are boring people.
