"drugs" ....hmmm... I assume you haven't done your homework about Ayahuasca. Shamans in south-america call it "the medicine", and the Ayahuasca ceremony is a very serious one. You can search for studies and stories (all over the internet), the reported results are usually far more helpful than any other traditional treatment. We use "drugs" every day, it is just a matter of using the right one for the right reason.
