well, as i am a noob to psychidelic's for now i am just a every once in a while pothead when i can aford to get a dime or quarter bag, but yes weed can be psychologicaly addictive, ive never been addicted to any but ciggs, but i do feal at times that in my mind i "need a join" b/c i do have depression and anxiety and the such but i never smoke b/c of it, i use it for recreational purposes of just having fun and taking journeys into realizations i need to see.
I've never tried coke, or the such but the thought of somthing man made bothers me, i barely even trust medication doctars prescribe nowdays, so which adds to part of it, also i cant put anything in my nose b/c its just very irritating, i cant stand anything going up there, i dont like the burning fealing lol. Although i do not have a problem against it or just parnaoid b/c its a bad drug, like you all stated its the user, not the drug who has the problem.
What i want to get my hands on which im trying to do at the moment is to experiment with salvia, hopefully if ever in this life DMT, peyote, mushrooms and the such, so i can see whats realy hiidden in me ; )
