If I have a minor consumption, open container and drug paraphernalia charges that were dismissed, can I enlist in the Army?

Maybe, apply and tell the truth. Lying is a felony that has a 180,000 dollar fine, 10 years possible jail time. Tell truth and take consequences.

Depends how bad they need the MOS you want. Talk to a recruiter, they’re the only ones who could give you a real answer.

Try a different one.
