be careful, the hallucinations are a lot more sudden than with mushrooms or acid, and ive heard that with ayahuasca, you have to take more dmt, around 300 mgs, as opposed to smoking it which only takes around 40 mgs, ive also heard that ayahuasca can be just as intense as smoking it, just less speedy. and it lasts for a good 4-6 hours. i dont know how experienced you are, but be careful. you definitely have to be able to let go, and just be an observer, kind of like a scientist experimenting with stuff.
