.I broke my back in 2 places in 1990 and have spent sooo many years addicted to pain killers , needing them to just be able to live through the daily pain! I now have my medical papers and find that the kush strains work best for my pain. It allows me to relax and just sit and be. Better than any narcotic Ive ever used. I am now growing lemon kush, bubba kush and kushberry. hope you try them. They work well for me.killer.
