I agree with you there. Although, I don't really think LSD, cannabis, ketamine, or ecstasy are addictive at all, other than being potentially habit forming, which just about anything can be.

I would just put alcohol more in the habit forming category though, maybe a bit more potential than cannabis over the very long term.

Opiates, cocaine, amphetamines, meth, benzos, and even Ambien are in another league.
