To the people saying you didnt get anything off it, you got ripped off basically or didnt smoke it properly(but this is very very hard to do). Basically, you need to be with 2 or 3 of your best friends(people you can trust), you need a nice bong, and you need a good place/enviornment. If you have any doubts about doing it, I'd recommend not doing it. I had a positive mindset going into and I tripped to fuck. We were chilling in my friends basement and I was lying on the couch after I took my hit, all of a sudden I put my head up and I couldnt see any part of my body, only my neck arms and legs, so I thought ok, maybe I'll just feel to see if my body is there, I put my hands where my body was supposed to be and all i could feel was the couch. After that it all went to shit, i could feel the house wrapping itself around my body, so I got up and ran into my friends yard and lay on his grass tripping out for about 3minutes. After that the hallucengenoic part started to wear off and it felt like I was mildly stoned for half an hour.
Also so you know rukas, salvia is an INTENSE hallucegan, and your mind state going into matters A LOT more than it does for a drug like weed or alcohol. Your mindstate before you do a hallucengenic is probably the most important part about doing it. You should think about that, especially if your not into tripping.
