Never seen a gun with a weed charge.
In general, convictions, not charges, affect gun ownership. However, you should discuss this with an attorney in YOUR state,
no
absolutely NOT!!!!
No! Actually, that depends on where you are and what the charge is. In the U.S. any felony will prevent you from buying a gun legally, but misdemeanors do not, except for misdemeanors of domestic violence.
It depends on the circumstances and the history of the suspect, but potentially, it will be the same charge as assault with a firearm, aggravated assault.
no
It sort of depends, but if the assault charge is still on your record, you will probably be denied by the TBI if you try to buy a gun in Tennessee. If so, you can appeal it, and it may or may not be overturned. Tennessee is one of only a couple of states that uses its own state system for gun purchases, instead of the federal system only like most other states, and they don't follow the exact federal protocol.
Arrested? Yes. Convicted? Not if the assault was a felony, or against a domestic partner.
Yes. As long as your charge was a misdemeanor and not a felony. You may have a delay in your ability to actually take the gun home if the background checkers decide so. But eventually you should get the gun.
