I'm a firearm enthuiast and can tell you that a cannabis related forum is not the best place to check for information. You need to first check your states Constitution and statutes as to the general provisions of firearms. Next, you need to check with your County and Local governments to see if they place further restrictions. For example, in Illinois, you can own a firearm. It is illegal to own a firearm in Chicago...state law vs local law. If you still have questions, a legitimate site like packing.org is full of knowledgable people, including LEOs, that can help you learn the proper information.
