I was arrested a handful of times for possession of CDS, however, 3 of them were nolle pros and one resulted in a probation before judgement, which my probation was set for 1 day. I am trying to research how long I would have to wait til I can purchase a firearm. The question asks if i am a current user, which I am not currently, but in the past, yes i was. Here is my question, since technically i never had a conviction for these charges, and all are able to be expunged, will this affect me in purchasing a hand gun? I refer to US vs Jackson 479 F.3d 485 (7th Cir. 2007). Which basically says he isn't a current user so he couldn't be charged with possession of a firearm and be a current user. If someone has anything to say about this issue that may be helpful ill really appreciate it so much, thank you.
