Right now, there is no unequivocal proof that medical marijuana helps treat chronic non-cancer pain. A review on this topic published in the Annals of Internal Medicine found “low-strength” evidence that some cannabis preparations may alleviate nerve pain, but not enough solid conclusive information on other types of pain. For patients like mine, who suffer from pain from nerve damage, there might be a benefit, but better studies are needed to prove it. Many patients with chronic pain don’t have nerve pain; they have pain from worn-out joints, or from irritated muscles, tendons or ligaments. For those patients, there is just not enough available information.
