About the back pain- it is a common use for mmj. Myself I am young, only 24. I was a good athlete, and had a few scholarship oppurtunities to play d1 ball, until my junior year. Was a football qb and got sacked brutally during a game. Long story short, I ended up shattering 3 lumbar vertabre, and slipping 2 disks. Serious spine trauma. So marijuana is the only thing on earth besides hardcore pain meds that allows me to work and live a semi normal life. I moved to oregon for this reason. God bless the great state of oregon to allow us to treat our pain without potent addicting meds.
