I have smoked salvia before, but didnt get the full effect. The best way to get a trip off of salvia is to not smoke or drink anything the day you feel like tripping. Get an enormously HUGE bong bowl, and put that in a 1 gal. gravity bong. And since salvia activates under extreme heat, light the WHOLE bowl up with a couple of lighters, and try to get the WHOLE bowl cashed into the gravity bong. Take the FAT rip and hold it in for 30 seconds. THese steps are what get you the hallucinations at the Full potential. Ive never done it myslef but ive seen it, and its fuckin hilarious. My friend did exactly just what i said, and he got blown into an alternate dimension, so he says, and from my point of view, its very much so possible! If you dont do exactly this method, you wont get the full potential of Salvia.
