No different from an applicant "forgetting" that vacation they took to China, smart guy.You can't say there is a negligible effect of having admitted to drug use on the initial interest forms for a police job because that's how it applies to security clearances for gov't desk and labor jobs. Because then you'd be talking out of your ass.
Oh, and the civilian guards at a lot of the government contractor facilities have better weapons than the city cops, but don't let facts get in the way. And they do draw their sidearms...just because someone has their badge tucked under a coat.
