I'll try CBD and Tinctures before I'll add to my cocktail Big Pharma med's for Parkinson's (and the side effects of this disease) as well as a mood stabilizer for treating my Bipolar symptoms. When I asked the prescribing doctor about the long-term effects of taking the anti-depressant and mood stabilizer, without lifting his head to look at me (was busy catching up on his notes), all he told me, in a calm but distant voice, answered, "(They) can't be good"). Gotta love these guys making $3-4 hundred thousand/year. Which leads me to the response to , "Anything that works that will not harm me." I approve of medicinal marijuana, but just because it's a natural herb doesn't mean it won't harm you. Just saying, drugs are drugs, and scientific research is often slanted due to the influence peddlers who sponsor the funding.
