I just recently learned that my cat has feline leukemia. He isn't suffering; he still does regular cat stuff for the most part. The vet said to pretty much just bring him in for "the shot" whenever he has no more quality of life. My question is, can marijuana smoke help negate his disease? I remember seeing something about how weed can kill cancer cells, I was just wondering if it could help him live happily a little longer than he would other wise.
