These commercials have been shown to only promote teen drug use.

The people siding with it are already brainwashed into believing what the institutions are feeding them. Preaching to the converted.

NORML Executive Director Keith Stroup said that despite Walters' promises, the White House ad campaign continues to have the opposite effect on teens than the one lawmakers intended. "This is a colossal waste of taxpayer's dollars," Stroup said, noting that the ad campaign costs an estimated $195 million per year. "The more often teens see these ads, the less likely they are to say no to marijuana and other drugs. Clearly, teens are dismissing these ads and their message as nothing more than government propaganda."

He added, "NORML believes there is nothing to be gained by exaggerating marijuana's harmfulness. On the contrary, by overstating marijuana's potential harm, our policy-makers undermine their credibility, and their ability to effectively educate the public of the legitimate harms associated with more dangerous drugs."
