Some 10-12 years ago, I used to teach a simple CompSci 102 course on a military base while in grad school. A drill sergeant taking this class was a veritable fountain of stories of military mishaps; one that he liked to repeat was that before Thanksgiving break, he would tell his new recruits that they would be tested for drugs when they came back on base, and encouraged them not to indulge. And when they came back, a non-trivial percentage would invariably be kicked out due to drug usage.

To me, this said more about how casual users think about drugs than about what they believe regarding Army regulations; a disparity between these outlooks that the Army (represented imperfectly by this drill sergeant) was unwilling to budge on.
