WRONG:

SUBSTANCE-FREE

An administrator at our university announced recently that his goal was a "substance-free" campus, which I suppose fits in with the growing fad of "virtual education." What he really meant was, of course, a campus free of illegal drugs and alcohol, designated "controlled substances" in the law. This is a very silly expression, but I suppose if he'd just said "sober and straight" he would have sounded too censorious. How about "drug- and alcohol-free?"
