A family relation of mine has been having bad back pain and found that JWH 081 was very helpful for him while being minimally "mind affecting" (at least in the tiny doses he was using). He asked me to buy some for him since it's legal and he doesn't want to do anything not legal. I'm a bit wary though because I've heard some things about JWH being cancer causing. Is this true? Any info on this or other health issues would be very appreciated. Thanks.
