I think I may be like you. EVERY time I smoke salvia, I never leave that weird stage in the beginning, so I never get hallucinations from that, I'v tried shrooms and didn't hallucinate once on that, the only type I have had were closed eyes visuals and that was from smokin a LOT of weed when the shrooms started coming down. I don't know what it is but I never experiance the same things my friends do. The salvia I smoked was 20x and never done any extract weaker then that. One time me and my bud were sitting on his backyard couch totally blazed, and we were passing a pipe loaded with salvia. Took around 10-15 hits and just felt REALLY strange, unexplainable, but still... no hallucination.
