Thank you for the article, and the research you brought to this subject. PD is such a horrible disease, and I believe more than ever, patients should be allowed this compassion and help. If the research is there, it is all political and a method to control. I am 60, and I hope in my lifetime, I see the release of THC into our health system to ease suffering. When I was a child, my neighbor Mr.Johnson had parkinsons. Even though I was young I saw first hand what this disease did to a brilliant mind and body. It took his last breath. What ever help there is for this disease, should be allowed. To not allowed this medical advance is not civilized. ginnie
