Hey Arizonian, welcome and look around some sites here. I have no clue how to get mmj in AZ or anywhere for free. Best thing I know, is grow it, provided it is legal there. Certainly is great for back pain, spasms and mood swings. What happened to your back. Getting pain clinic-rehab? If not, Look on some medical sites and start with some mild stretching each day and gradually build up your collateral muscles to compensate. MMJ is helpful, but you need to address your problems at your age. Exercise is good for all the conditions you mentioned. Sure, it is hard to get out of bed, but too long in it will increase your pain, in most cases. Good Luck to you. PR
