I am currently researching San Pedro cactus for its medicinal properties. They are similar to Peyote and Ayahuasca in many respects, but the best part is that they can be legally owned in the U.S. Look for a movie scheduled to be released at the Sundance Film Festival this Fall, September 10, 2019, by a producer named Jerry Toth. Or, just google https://www.google.com/search?q=san+pedro+cactus+jerry+toth&ie=UTF-8&oe=UTF-8&hl=en-us&client=safari
