2.      Drug Use – Ditto for drug use as well.  Never tell students the “I didn’t inhale” speech, or the “I have a friend who tried meth once and now he lives in a cardboard box down by the river” speech.  Stick to simple statements like “Drugs are bad”, or “Drugs destroy lives”.  Also, even if you feel very strongly about the subject…and think that the government could make billions taxing it, NEVER insinuate that any drug should be legalized!  There’s no good ending to that story.
