Sorry if this isint the right place for this question. So I've seen 1 or 2 post regarding this both being about 1 to 2 years old but basically the same question can you buy a firearm while being prescribed methadone by a clinic I saw that there was more than a few people saying they own a gun and we're currently on methadone for year's but I also saw some people saying they were denied but didn't know if was because of the methadone or maybe an MMJ card, I just wanted to know if anyone had any experience with this recently? I saw an article online from this year 2023 stating that “US COURT RULES DRUG USERS CAN NOT BE BARRED FROM OWNING A FIREARM” also in “AUGUST 2023 a federal appeals court struck down law barring users of illegal drugs from owning a firearm” so in my situation im buying one from a friend a Springfield XD9 (he got a new glock) for a very good price! We did a PPT private party transfer on the question “Are you an unlawful user of or addicted to marijuana or any depressants stimulants narcotic drug or any other controlled substance” I put NO which technically it wouldn't be unlawful because there's a prescription and the way it's worded I would says states if you are currently addicted to any unlawful substance which would be NO just being in a clinic would obviously indicates previous addiction but I just wanted to see if anyone had experience with this situation?
