its dangerous to say salvia is a key to happiess, it may be a key, to happiness after the trip, if u can handle it, but it can be overwhelming and so intense you can be messed up in the head for a long time after.
can u imagine the trip chasing you through the house!
or your skin feeling like its being torn off?
or laying on top of a moving escalator hurting like hell?
hapiness = afterwards when u realise ur ok and our world aint to bad!
