I only use Psychedelics. I drank and drugged for 30 years and then spent 10 years completely sober. Even sober I always knew Psychedelics were a very different, important and useful class of drugs. My views on other drugs?
Cannabis - I was saturated in it in my youth, but it makes me want to weep and hide these days, the paranoia is so bad. I would consider trying it again very very carefully as I think it might help me with some frustration/impatience issues I have.
Alcohol - It cost me plenty. Can't use it.
Sedatives - See Alcohol.
Amphetamines - Did them several times and apart from the novelty they felt like stress. I'm glad they aren't something my brain craves.
PCP - Did it several times, back in the day. A low dose is a nice high, but a larger dose cured me of ever wanting to do it again.
Opiates - My former drug of choice = No can do.
Cocaine - Is the Devil. I hate Cocaine. It is a degrading experience and the comedown is horrific.
Ecstasy - I really enjoy it but the comedown is like a slow motion cocaine wreck, so I can't do it.
Caffeine - I'm still a caffeine addict.
