I had a long chat today with a dispensary employee. He gave me interesting information I wanted to share with you. First he said CBD may be oil, cream, or other product that is smoked. All CBD has at least trace amounts of THC. However you can get CBD which has almost all THC removed.
CBD does help for muscle cramps. There are different types of CBD that can be used on the skin to numb the nerves in a specific area, and others that are taken internally as a general muscle relaxant for the entire body.
I was thinking I was only interested in CBD where almost all THC was removed. However he said that doctors have told them that THC and CBD work together in the body, so you would probably get more relief from cannabis which still has a some THC in it, which would not be enough to effect your functioning. He also said that some people get more relief from smoking cannabis.
When I asked about whether cannabis would help with Parkinson's, he said they just don't have the medical research to prove it yet because until recently there has been no funding for medical cannabis research in this country. He also said the best research has been coming from Israel because they have been doing research there for a long time.
They have had customers who said cannabis helped with Parkinson's tremors. But at this point you simply have to try different products to see what if anything works for you. If you find something that works and you are a resident of a state that has medical marijuana, you may be able to have a significant sales tax savings by getting a medical marijuana license.
