As a responsible firearm owner, I have been following this topic closely. Here is one example https://www.nepr.net/post/feds-pot-and-guns-dont-mix?fbclid=IwAR3COjUmSq_mNl7Tn7eAxVwRLawZ5vV9yeSBfv_SeOSnKBIkV6jiDrm-qts#stream/0
From your article...
“If you answer falsely on this question here, on ‘question e,’ if you answer no and you actually are, you’re subject to a felony charge for lying on a federal form,” he said.
But O’Shaughnessy said no one has been arrested in Massachusetts for answering the question falsely.”
And if a pot user answers truthfully, they cannot purchase a firearm. That is certain.
But nobody is going to take any firearms you already have and put you in prison because you are a casual or medicinal user of pot.
And that was your assertion. It just hasn’t happened.
