I recall of a group in the south using ayahuasca for a frequent ceremony who were raided and charged for dispensing a class A substance, but I never found out the outcome. It was a couple who lived on a farm who were conducting the ceremonies, yet I can't remember exactly where or any names. I just remember signing the petition, maybe 2-3 years ago.

Anyway, the bottom line is, be careful.

I'll search through my emails, where I think I received this information and post back with the info if I can find it.
