I'd go with NA since it sounds like msot of your problems are with drugs & NA is a little broader than AA in they treat all substances the same, a drug is a drug, is a drug. We're having a bit of a split amongst groups up here in AA as to whether it's ok to identify as an alcoholic and and addict at aa mtgs. sometiems addicts come to aa mtgs simply because there are more of them, but recently some groups have started adding a line at the beginning of meetings that says "if you have other addiction issues, please at this meeting identify only as an alcoholic and share only about your problems with alcohol." which personally I think is a bit of overkill.
