What he's asking for is more akin to diphenhydramine or datura honestly, and neither of those is "awesome", just kind of interesting. Really there's a whole range of hallucinogenics that are all totally different. Acid, DMT, Shrooms, Mescaline, and the like are good for insight and good experience, dissociatives (pcp, ketamine, dxm) are good for total mind trip and a more "inner" experience, and deliriant anticholinergics (datura and diphenhydramine) cause you to see and hear things that are not there, and not be able to distinguish these as real or fake the more delirious you get (and the more obvious these things are not real should be, but actually isn't). I find that the closest legal substitute for good hallucinogens besides getting LSA seeds or anything like that is to mix dxm and diphenhydramine. Feels intense, you hallucinate, but it's definitely it's own trip, not really like acid or shrooms.
