Well, just how much is some? Currently, AFAIK, different states have different guidelines. In Ohio, you mush have over 100 grams to be considered a felony possession or smaller amounts packaged individually to be considered intent to distribute. Anything under 100 grams is still a misdemeanor.
It really depends on the state - some states have revised drug laws to be a little more lenient, while others still have laws on the books that make possession of any amount a felony
Having a drug conviction doesn't discount you from owing or possessing firearms, but a felony drug conviction does
