> I've had and heard of very significant positive experiences from substances, and yet also, obviously, many people become alcoholics all the time, or become barely-functioning stoners who "wake and bake" every single day and are incapable of really anything anymore.

_Almost everyone_ who uses recreational drugs or drinks stops drinking or doing drugs _on their own_ without any intervention. There's this idea that's been propagated that drugs are this evil demon that you can never shake once you get addicted, because for people who deal with drug addicts professionally, _all they ever see_ are people who haven't quit drugs almost by definition. However, those drug addicts are a _small_ percentage of all the people who have used drugs.
