Fortune.com has an article that addresses this very controversial topic.
If you obtain a medical marijuana card..are you still able to legally purchase firearms ?
So lets imagine the veteran who chose to serve our country, and who now uses medical marijuana for his/her PTSD ( or whatever reason he/she needs it) and still enjoys the "right to bear arms".
With the new ruling...its not going to happen !
According to the article
"A lawsuit was filed in 2011 by Nevada resident S. Rowan Wilson after she tried to purchase a gun for self-defense and was denied based on a federal ban on the sale of guns to users of illegal drugs. Though marijuana has been legalized in some places on a state-by-state basis, it remains illegal under federal law."
