I am referring to people who can NOT do without behavior modification substances, legal, illegal, off the mini-market or the drug-store or the street, it makes no difference.

YES it is all over the literature, anti-depressants took up the slack of smoking and drinking quitting markets. From Big-Tobacco to Big-Pharma the goal is profit, and Prozac is one hell of alot more profitable than a good cigar. From Delaware to Georgia you have to use chemicals to stop tobacco from growing or use hybrids that are incapable of reproducing. Even if you can make Prozac in your kitchen you can't sell someone's patent.
