here's some great info on making cannabis tinctures...also my latest and best therapeutic hobby...its fun to do like a craft, but it also means serious medicine for us. If you dont already have a MMJ medical Dr. recommendation /card...I'm sure Oregon has it..then I dunno what you would be waiting for. When I was (and still am ) treating myself for devastating Lyme Disease,I looked for Anything and Everything I could find or learn about that would help me to heal. and including the standard Pharma treatment process, I was most passionate about learning on my own all the alternative therapies there were that might help. I did accupuncture, reiki/energy healing,from a 'body worker' energetic body work...it was actually one of the best healing moments.releasing deep psychic stress of the trauma. I learned about herbal medicine,vitamin therapies, many things. now I'm making cannabis tinctures at home and it is very good medicine.
