Even though smoking is dangerous (Though on my mother's side, my grandma has been smoking since she was like 16 and she's now 83 i believe? still alive, no cancer, no nothing...) I read an article today that said nicotine can help pervent the formation of a neurochemical in the brain, which is linked to Alzheimers disease! So...at least I know I won't end up being senile if i smoke!
