Alcohol: a couple of beers gives a nice lightheaded feeling. But don't make the mistake of thinking:"ah, that feels nice, i want more of it".

MDMA: yeah, nice. Not realy something to do very often.

Coke and amphetamines: boring.

Cannabis: cannabis can be psychedelic if not taken too often, because then the magic wears off of it and it becomes more like an ordinary sedative. Oral cannabis can be realy fantastically psychedelic and euphoric.

Opiates: the only opiate i have experience with is kratom. I like it but it's not realy like it opens up a whole new world or something.

benzodiazepines and GHB: feels like toxic waste to me. I hate it. I prefer a couple of beers over any other GABA-ergic. Though 'the wolf of wall street' made me curious about that lude-stuff. I don't think i'm realy gonna try it though.

NDMA-antagonists: Nice, but not nearly as nice as classic psychedelic's. Except for ibogaïne. I realy like ibogaïne. When it's taken in small bits over the course of one or two days, there is no nausea and puking and it's realy entertaining. Very psychedelic. Even compared to ayahuasca, LSD, mescaline or shrooms. Though ibogaïne is not something to do very often either. It would probably wear you out.
