Earlier quoted context omitted.
Aren't most recreational drugs addictive and destructive? It's not too hard to understand why there's a stigma.
Primarily just those which result in dopamine production are addictive. Psychedelic drugs do not, and are generally not addictive.
Dependence on drugs that mess with the dopamine system (nicotine, caffeine, amphetamines, cocaine, etc.) is almost completely psychological. The physical withdrawal symptoms are slight in comparison to the category above.
Psychedelic drugs mostly mess with the serotonin system, which has a lower (but non-zero) propensity for producing psychological addiction, owing largely to the fact that the tolerance curve is very steep and it takes the brain a few days to reset.
