Oh boy.
I don't know if salvia is what most people call "tripping". Does it even have a name other then "doing salvia"?
If you are able to figure out what plant you will get you high and where to get it, just have someone sober around when you do it. You might not ever do drugs again, you might find a button you want to push, but salvia is like nothing else.
I can say that it is the only drug I've ever done that terrified me. Not scared me like "Oh! I'm Gonna die/am dying/have died!" or "Hey, will you feel my crotch, did I pee my pants?" but like there's nothing but "I"- there is no death, no life, nothing but me, existing in nothing and that's scary stuff. Not to mention the loss of motor function. That said, it is really pretty cool and not traumatic in the way a serious hyperslap can be.
Just be careful, be safe, be wise.
