Many people with psychiatric challenges (both acute or chronic disorders) will often seek self-medication options. Marijuana is indeed a mild hallucinogen, but you are correct in that many hard drugs can trigger a psychotic episode. Often illegal dealers lace the stuff with addictive compounds that cause severe problems during withdrawal.

Having a family member with active untreated disorders can tilt the odds out of ones favor, but those with intellectual gifts also tend to be more resilient to such situations.

Understandable, after a few years people see the same excuses, exploitive scams, and rhetoric. The Sackler family ruined a lot of lives to capture that money, and I guess a few psychopaths saw a business opportunity.

Best of luck =3
