This is not how drugs work. A lot of weed can be as intense as low dosage acid (especially edibles). The big difference is their strength. Even acid, as long as you aren't taking some crazy high dosage, more often than not you just sit around and chill and think weird thoughts. Contrary to what most people think, acid isn't all that visual of a drug (until you get into very high doses).
Just google caapi plant jaguar if you want more.
Animals have been getting high for untold eons, i don't think this should come as any form of surprise.
