Mario, this is very interesting. I quit smoking after 32 yrs, 16 yrs ago with no trouble at all. My smoking friends who couldn't stop hated me for that. I had been cutting down due to chemo to one smoke a day and simply didn't want to smoke anymore. Strange I was able to do that if my dopamine levels were so low. Haven't we been hearing lately that smoking may prevent PD? This is getting too complicated.
