There is a common misconception going around… that I would simply like to put to rest as it pertains to the individual state legalization of marijuana, and whether or not people who partake in state legal use of marijuana may legally purchase or own a firearm.
The confusion derives from the fact that the state legalization of the drug in question is only legally prescribed per the state level, and not the federal level, which supersedes it, and where it is still not legal.
So what that means to you is, that if you own a firearm, or would like to purchase a firearm, per the 4473 form, which is the form all of us federally licensed gun dealers have customers fill out before purchasing a firearm, it clearly states the following via the question pertaining to marijuana (legal or illegal) use:
“Are you an unlawful user of, or addicted to, marijuana or any depressant, stimulant, narcotic drug or any other controlled substance?
Warning: The use or possession of marijuana remains unlawful under federal law regardless of whether it has been legalized or decriminalized for medicinal or recreational purposes in the state where you reside.”
Which of course is a “Yes or No” question on the 4473 form referenced above, and if answered yes, the individual attempting to purchase a gun may no longer do so, per current federal law.
With all that being said, if you do apply to use state legalized medical marijuana and are successful, you will no longer legally be able to own a firearm(s), and will also revoke your right to purchase any new guns as well post prescription.
