I removed the addictive part. This substance can have dangerous side-effects and bring you to the hospital, so it doesn't need to be addictive to hurt yourself.

> You are harming your family and friends by harming yourself.

What of drinking alcohol? Eating too much food? Riding a bike without a helmet? Taking an antidepressant with known potentially dangerous side effects? Going outside without a jumpsuit made out of Nerf foam? At what point do you get to live your life for yourself instead of avoiding doing things you think others might not want you to do?

Of course. The point is that there is a scale of dangerousness. What are the odds of getting an accident riding a bike vs taking drugs like these ?

I think jumpsuits should be forbidden for the same reason, but that's just a personal opinion.

Surely, but I think your danger meter may need recalibration here. Dying of toxicity of psilocybin is practically unheard of (unlike with alcohol, for example), and while there are no solid stats on injury/death related to behavior while on this drug, it is considered the safest of recreational drugs according to a recent global drug survey: https://www.theguardian.com/society/2017/may/23/study-halluc...

Given the chances you'll be riding your bike among cars piloted by people on prescription painkillers or alcohol, I'd be surprised if riding a bike isn't significantly more dangerous than taking psilocybin, but once again, there are no good stats on psilocybin-related behavioral results so this is just speculation.

What exactly are the dangerous side-effects of psilocybin? Yes, you shouldn't drive or make big decisions while on it, but that's not hard to control for (and is similar to many OTC medicines). What are the side-effects that are sending you to the hospital?
