Whenever government and government-paid program people get together with a large budget, the principle of the "Unintended Consequence" is sure to come into play. Cops see this every day with newly strong criminals, who are back in action after a short stretch in the slammer. The recidivists are bulked up from regular meals, intensive body building, and of course their drug and alcohol intake will have been somewhat curtailed. They become too strong for the cops to subdue.
Ditto anti-drug commercials, which have the unintended effect of glamorizing the forbidden.
The anti-smoking commercials are even worse. The only decent anti-smoking commercial was put out by ydouthink.com. It said showed a teenage girl waxing her moustache, and said "Girls who smoke are 7 times more likely to have excessive facial hair." The target audience was narrower than most, but it was alot more effective IMO than the "rat poison" or "dog urine" commericals.
