hallucinations are not the same thing as visual effects.

you don't see things that aren't there on dmt, psilocybin, lsd, you see them distort and have pretty patterns on them but not fundamentally not there. If you want to hallucinate, you need to eat datura or brugmansia or amanita.

hallucinating is a very bad thing. Most people hallucinate that the government isn't out to rob them of every last penny they can get away with. Most people hallucinate that their phones are not spying on them. Most people hallucinate that it's ok to be 20kg or more overweight.
