Furthermore, my point on psychedelics was about psychedelics, which was the context of the comment it answered, not heroin.
Alcohol is also associated with violence, both public and domestic.
Psychedelic use is none of those things. Psychedelics in general are far less likely to be addictive, use is not associated with violence. There are some health effects, LSD for example is a stimulant and vasoconstrictor, but in general they are not taken in large enough doses or often enough to cause harm.
I think your hunch as to who you would rather be around is a bit weird, frankly.
Can you elaborate a bit on this take? We've all seen how far people abusing alcohol can go. Where as the worst I see from psychedelics users is that they can struggle to talk about anything other than how've they've somehow figured out the universe and that everyone should take psychedelics.
It's the addiction that's a bitch. Of course heroin street addicts end up in bad shape-- but a lot of that is from tangential effects, not directly from the drug itself.
