It sounds like you want psychedelics, but I'd highly discourage them. There's a certain purity to marijuana, if you can control your habits, that you won't find in psychedelics. And it's also a lot safer to get busted with, as well; if you really want to look at the worst-possible-scenario.

Marijuana is relaxing, and paradoxically stimulating. If you're aiming for a substance higher than mushrooms, you're kind of looking at flirting with a different and potentially more dangerous lifestyle, my friend.

The propaganda about marijuana is false. The propaganda about harder, psychedelics drugs is more or less true. Stick with weed. And if you really want a trip, then just try shrooms.
