This article says that “there may be some fundamental difference in susceptibility to nicotine addiction between people who develop Parkinson’s and those who don’t.” If so, how would you explain the fact that “after smokers stubbed out their last butts, the protective effect faded”? Tobacco smoking is becoming unpopular, and for good reason, but I hope the “evil” of tobacco smoking will not stop scientists from at least considering that there might be some benefits to it. Many drugs are poisons.
