Hahah yeah, I've been told this. Or not even about shamanism, but like those who use power-plant are inferior and cheat those who don't use them and are more evolved.

Have you heard stuff like that ? for exemple ayahuasca work isn't a right path, you need to work on meditaion like a straight head etc...

I think it's all church's fight in my opinion, though as a psychedelic user, I always tell poeple they do'nt need to do it if they d'nt feel like. Maybe what I gain from it, won't gain to them etc...
