I havent but... I get the suspicion the effect would be negligible because from my experience acid is stronger than salvia
since some salvia experiences are very frightening this may be a high risk experiment. anyway I've been wanting to try it but haven't scored any acid lately. I'd imagine the salvia would overwhelm the acid for about 2 minutes then you'd return to your lsd trip. the weird part would be trying to integrate your salvia trip while on an acid trip.report back if you try it.
I did once, but the salvia just affected the visuals I was getting instead of going into the selfless mindfuck that is salvia. All the patterns I was seeing shifted into more geometric patterns as opposed to curved patterns.
Well during my first acid trip my friend had a salvia flashback and after that the trip went kinda downhill cause both our trips somehow got interconnected. Its weird but everytime he would start freaking out it would negatively effect me and since we could read each other's minds it became even harder. I tried salvia a week back or so but I didnt really trip on it cause I was smoking it wrong so I wasted an entire gram. You are meant to hold in the hits for as long as you can, I wasnt doing that. But the feeling is very nice, I would say its very similar to the acid rise where you that woderful feeling of everything being perfect backed by those amazing visuals. After that I just felt that I was stuck to the floor. Personally I myself would not take the risk of doing salvia together on acid, I would rather take more of the acid but make sure it is an acid trip and nothing else.
Dude on my last trip I thought I was inside an autocad software where everything was made of a framework. The floor, walls and the ceiling were all like a box of patterns which came from under my feet and followed me everywhere, all the way downstairs onto the street. It was amazing.
