I recently was certified for medical marijuana. I have tried several different kinds and finally have had great success with CBD drops. They are a 10:1 ratio of CBD to THC. I was told that CBD works best when it is kept in your system constantly. It has helped tremendously with my sensory neuropathy cough. After many many years I have found some relief. I am still currently taking tramadol but would like to see if I can wean off of that and just continue with the CBD drops.
