I tried normal cannabis (would've been high THC) and it utterly messed me up. Still have terrible terrible dreams even months afterwards. The cannabis was so expensive and honestly the benefit was really really minor for my needs. I would've been MUCH better off just juicing carrots oranges and ginger - cheaper, more effective for me, and a heck of a lot safer.
Benefits were totally exaggerated. Don't bother.
Instead I recommend:
- have look on earthclinic.com
- get a heat lamp for pain & muscle spasms
- do fresh raw juices / fruit fasts
- massage painful muscles with oil
