"The question that needs to be asked is: Why don't children believe those who warn them about the dangers of cough syrup? The answer: Because when the drug war cheerleaders lie about or grossly exaggerate the dangers of marijuana, they lose all credibility.
When children find out that they have been lied to about marijuana, they make the logical assumption that they are also being lied to about the dangers of other drugs like meth, heroin, household inhalants and cough syrup. A recipe for disaster."
