It's nonsense to fire someone for doing drugs in their off time. Military or civilian. You know how many lushes, drunks, and full blown alcoholics were in the Navy when I served? The E-Club was packed every single night. Yet nobody really cared as long as you didn't get in trouble, get hurt, or show up for duty drunk or unable to work (or of course if you were on 24 hr call). But if someone prefers weed or coke instead of booze? OMG kick 'em out now, we can't have any of that riffraff in our fine establishment!! SMH
Almost our entire drug policy is bass-ackwards and hypocritical. Responsible use is nobody else's business but the user, and addiction to drugs is inherently a medical problem, not a criminal problem. Minimize drug abuse through education and deglamorization, not through criminalization and incarceration. What we're doing today doesn't solve any problems, it just creates more.
Anyway, too bad for Ensign Biden. He might have turned out to be a decent officer if only he had celebrated his direct commission with everyone's drug of choice instead of his own.
