The guidelines have changed in the last couple of years. With the exception of certain agencies(FBI and DEA), drug use is evaluated with the surrounding circumstances. They treat I smoked pot once in college or I dealt pot or I am currently addicted to heroin differently.

The guidance these days is to tell the whole truth and describe the circumstances. Lying on the form will definitely disqualify you and a couple dumb things a few years ago won't necessarily.

Don’t apply
