I take steroids for allergies. Did you know that methamphetamine is also an effective ADHD drug? Cocaine is a great painkiller for facial/nasal injuries. Then again, there's a whole class of illicit drugs that make effective painkillers.

The point is, just because your DARE teacher told you to to say no to something doesn't mean that a doctor shouldn't prescribe it and a patient shouldn't take it. Sometimes, drugs that are harmful in the wrong dose are good when prescribed and taken correctly.
