> doing regular meditation will reduce the chance of bad trips or at least let you deal with them much better. Perhaps, but meditation as it is often practiced by lay people is one of convenience. That is, this is pleasant, I'll sit for an hour, but not more, because that would become unpleasant (to my knees and back). I don't think this kind of practice does anything to prepare you for the rigors of deep psychedelic experience, where control and choice go completely out the window whether you like it or not. A one week meditation retreat, with 14 1-hour sittings per day, however (i.e. Vipasana, Zen, etc. style retreats), that will help for sure, though I suspect none but meditation masters can emerge unscathed from the psychedelic deep dive.
