Well.. i don't mean to explore carnally or sexually.. but i mean mentally... if you want a good site to visit explain almost everything there is to know about ways to litterally change the human mind's state go to:
http://www.erowid.com
it's a great site explaining ways to mentally change yourself, as in mentally and spiritually.. and also what narcotics there are and in which ways they effect the way you work/see the world/percieve things and everything else there is to know.
personally one of my favorite parts of the site is to look up strong drugs like salvia (strongest psychoactive i know) and to see what kind of experiences the people get from them.. like bad ones, bad trips.. good trips.. funny things ect ect... try it out its fun. (try it out as in go to the site)
and no i'm not promoting psychoactives.. im jus showing the site.
