This is a subject I have a lot of interest in -- psychedelics for medicinal purposes. I traveled to the Amazon Jungle about three years ago and used ayahuasca for my depression. I wrote an in-depth article about it on Steemit.
If you haven't read the book, Acid Test, I highly recommend it. It's about using MDMA for PTSD. EXCELLENT read!
I'll look it up, thanks!
