One method that I have found is using a vaporizer. I have seen many videos on you tube and the effects are incredible. I have been diagnosed with polyneruopothy and I use cannabis for medicinal purposes only. I have not been given any pills or help my my neuro (who can't seem to figure out what is going on). I can say that in my personal experience it has helped huge. It doesn't harm my lungs because vapor is different than smoke. I do get a bit of a high but that can be changed if you ingest the cannabis. cannabis has been seriously misunderstood. The only side effect I can report is hunger afterwards. It helps with my muscle spasms though, only this that does.
