What is a safe hallucinogen?!
Question:
What is a safe hallucinogen?
Answers: Hallucinations occur when your chemistry is altered. As far as I know there is no drug that can do this without the possibility of negative side effects--LSD, mushrooms, Ecstasy, mescaline all have the potential for irreversible negative mental side effects.
Try staying up for 48 hours straight. You'll hallucinate plenty then. Source(s):
pd Yep that's what I was gonna say, force yourself to stay awake for a long time, a couple days wouldn't do any major damage to you.
