Like, I really believe that if I had not quit smoking, I would not have developed PD, eh? What effect does Nicotine have on the brain anyway? Does Nicotine kill the transmitters? Does the brain produce more transmitters to make up for the transmitters that Nicotine kills? Isn't Nicotine a poison? And what about the Nicotine Patch and the Nicotine Gum? Do the patch and gum also kill transmitters? [log in to unmask]
