Working on the subtopic 'Effects' under 'National Youth Anti-Drug Media Campaign': http://en.wikipedia.org/wiki/National_Youth_Anti-Drug_Media_Campaign
Reports measuring the outcomes of the campaign indicate a lack of affectivity. Though the messages succeeded in reaching many youth, findings do not point to the achievement of the desired results.
The National Survey of Parent and Youth (NSPY) was a instituted and funded by congress, to monitor and assess the NYADMC's effects on youth.Cite error: A <ref>

(see the help page).
Even though the advertisements themselves were only as specific as to address use of marijuana, the NSPY measurements reported alcohol consumption, binge drinking, cigarette use, and use of marijuana/hashish.
The assessment consisted of multiple rounds of strategic questioning between years 2000 and 2004 to determine youths exposure to the advertisements, and behavioral patterns in relation to marijuana use.
94% of youth (ages 12.5-18) reported exposure to at least 1 anti-drug message per month. Overtime, those sampled didn't marijuana usage within this time period. Youths claiming to have used marijuana within the past year in 2000 accounted for 17.1% in 2000, and dropped as low as a .4% decrease with 16.7% in 2004. However, there was a .4% increase in those claiming to have used marijuana within the past 30 days, rising from 7.8% to 8.2% between 2000 to 2004. There are also evidence of pro-marijuana lagged association effects.[1]
the rate of acceleration in use was quicker at among 14-18 year olds than at earlier stages of teenage years.
Not only do data indicate ineffectively, results also point to a behavior in the opposite direction, or a boomerang effect. Of those unexposed to ads on a given month, 81% did not intend to use marijuana, That percentage decreased for youth exposed to 1-3 ads per month, to 79% and dropped to 78% among those exposed to more than 4 advertisements per month.<ref>
