No I had a clearance required position in the military along with my coworkers and they're actually primarily concerned about two things: Honesty when filling out your form SF-86. Are you gonna lie about being contacted by a foreign agent in the future just like you lied about smoking a couple puffs in high school? Lie on the SF-86 and get caught and its instant permanent deny. Blackmail opportunity where if you have a current or likely future addiction a foreign agent could provide you with money or drugs or silence in exchange for info. So a couple puffs in high school, who cares, on the other hand stripping copper to pay for meth last week is instant deny. Same blackmail issue for credit report issues. In the really old days it was the same thing for non-hetrosexual people, if they figure you could get blackmailed then no clearance. There's a lot of hand wavy but assuming you're functional in the sense of not being high at the interview while also not being the most financially insolvent person in your future department, the only real way to fail a mere S or even a TS is to lie on your SF-86 when you apply. The vetters have a rough subjective job so they really like finding an objective factual falsehood like a misdemeanor possession or similar, because then they can take it easy and stamp deny.
