haha I hope you guys all know you really CANT trip off adenochrome....that was just a rumor that came from Fear And Loathing In Las Vegas(great movie)....Id have to say any of the belladonna plants(datura, nightshade, etc) have got to be up their since it breaks the barrier between knowing your tripping and not even knowing your on drugs...just walking around in a dream(more like nightmare) basically...drugs like LSD are really intense but you still know your tripping......their are so many halucinigens...and I guess its to each his own, since everyone reacts differently to every drug.
