Marijuana/Weed Alternatives?

Its always a project for school......anyways you asked a question and regardless of your real reason im going to answer it, I have personally done salvia divinorum 3 times a href="http://en.wikipedia.org/wiki/Salvia_divinorum" rel="nofollow"http://en.wikipedia.org/wiki/Salvia_divi…/a I smoked it out of my bowl and after holding it for 30 seconds i exhaled the effects were instant everything started melting and starting going in slow motion i was hit with a sudden panic as i realized only a few seconds in that i didn't like what was happening everything looked like claymation or a cartoon i had i fight with myself debating if i was in reality or not if anything i did actually happened or if it was my imagination a fantasy so to speak, i soon thought i was going insane and doomed to stay in this effect forever. while the effects lasted minutes i thought it lasted forever....ironically afterwords i felt fantastic perhaps because i was just relieved to be out of that effect. it compared to weed....if that said weed was laced with pcp, acid, and dmt
