I never used any kind of drug. However I had toxic chemo that contained nitrogen mustard like the mustard gas of WW. My grandfather who had PD didn't even drink or smoke, let alone use drugs. We were not young-onset Parkies. I've read MJFox's book and there is no mention of anything other than alcohol. However, I think this question is an appropriate one and should be asked.
