Nice depiction of you concept. I dont really know too much about this topic. Although, I do remember back in school hearing something about people being born alcoholics. I just look at it a little different, but then again I look at a lot of things differently then most. I dont think youre born with a potential to be addicted to any one drug or the other. I just think some people have a weaker tolerance for different things. Like you can have two guys the same size and age, but one can drink the other guy under the table and still be fine, his body just has a higher tolerance. But to say theres an actual gene that says your and alcoholic, youre a smoker, youre a coke head, I dont know, it just doesnt seam likely but like I said early, what do I know, just my thoughts. :D
