out problem pilots has been a cultural change.

That cultural change didn't come about until drug testing was instituted.
Chicken and egg kind of thing.

The truth is that if someone really tests positive on the tests, then his
co-workers probably already knew about his problem. I think most testing
centers would be hard pressed to come up with an example of actually
finding
genuine abusers that no one knew about already.

I agree with you as far as social abusers are concerned (drinking alcohol
and smoking marijuana). However, I disagree with you when it comes to
prescription drug abusers. People addicted to pain-killers,
anti-depressants, and other illicit pills may be closet users. Many times
their own families aren't aware of their dependency. How about heroin? Ever
see any pilots shooting up at the bar? Is a heroin user going to want his
colleagues to know about his habit? Will his non-aviation user friends care
if he flies at less than 100%?

Eventually, the abuser will have to decide if they want to get high with
drugs or with an airplane. That is the worth of testing. It doesn't happen
overnight. Without drug testing regulations, it may never happen, until it's
too late.
