Interesting, yet uninformed comments. First - Ayahuasca is an enthogen not hallucinogen. Look up the difference.
Second - This chemical compound can not possibly be used as a street drug. You don't get high even though it can be way more euphoric than sex.
Third - It is comparable to, but maybe not as strong as a American Indian peyote ceremony. The "vision quest" achieved can lead to long term understanding or clarity (even if you never do Ayahuasca again.) I have also seen people go completely off street drugs after just one Ayahuasca "trip". Not because of a chemical change, but because any drug, even heroin, does not compare to the experience of a controlled Ayahuasca experience. Plus you remember with fine details most of the experience and understanding gained.
Finally - making fun of how someone looks as a basis to criticize a religious experience is pretty juvenile. How many people made fun of Jesus' dress, Muhammad's (or his followers) beards, Buddha's fat stomach, the Dali Lama's face. Pretty short sighted bigoted response. Good luck with that.
