Don't forget, they sell "patches" for tobacco addictions which don't word so well because tobacco contains over 200 pschoactive chemicals and the only thing the patches give you is nicotine. Tobacoo is great because it actually binds to Mu (heroin) receptors, as well as those stimulated by Ecstacy. Albiet it much more weakly. When you do Tobacco, you do a few drugs at once ... again, albiet in doses much lighter than a straight-up user of any of the individual drugs. This is why it's so hard to quit. When you quit tobacco, you aren't quitting one drug, you are kicking a few drugs that you have been using in very low doses for decades. And just like heroin users cease to get high after a few months and have to use just to maintain or feel "right", this is pretty much the experience with tobacco. That initial head-spinning nasuea goes away, and you have to smoke to stay straight.
Everyone is an addict. To something. Maybe it's running, mabe it's food, maybe it's sex or gambling or porn or caffeine or television.
It's your right as a free person to be addicted to whatever you want, so long as you are not hurting someone else. And if you do hurt someone else, it is the action of hurting that should be illegal, not what you ate, drank, smoked, or watched on TV before you committed the act.
