HARRISBURG, Pa. – The federal government says grass and guns don’t mix, and that is putting gun owners who use marijuana – and the strongly pro-gun-rights administration of President Donald Trump – in a potentially uncomfortable position.

As Pennsylvania becomes the latest state to operate a medical marijuana program, with the first dispensary on track to begin sales next month, authorities are warning patients that federal law bars marijuana users from having guns or ammunition.

“They’re going to have to make a choice,” said John T. Adams, president of the Pennsylvania District Attorneys Association. “They can have their guns or their marijuana, but not both.”

That’s the official line, but the reality of how the policy might be enforced in Pennsylvania and other states is a little muddier. That includes the question of whether people who already own guns might have to surrender them, instead of just being prohibited from making new purchases. The political sensitivity was underscored Friday when Pennsylvania regulators reversed themselves and announced its registry of medical-pot patients will not be available, as was previously planned, through the state’s law enforcement computer network.

Phil Gruver, a professional auto detailer from Emmaus who received a state medical marijuana card in mid-December, is weighing what to do with his .22-caliber rifle and a handgun he keeps for home defense.

“It’s a violation of my Second Amendment rights,” Gruver said. “I don’t know of any time anyone’s been using marijuana and going out and committing acts of violence with a gun. Most of the time they just sit on their couch and eat pizza.”

Attorney General Jeff Sessions has long denounced marijuana use. Sessions recently rescinded a Barack Obama-era policy that was deferential to states’ permissive marijuana laws. Now, federal prosecutors in states that allow drug sales must decide whether to crack down on the marijuana trade.

The Justice Department’s Bureau of Alcohol, Tobacco, Firearms and Explosives has left no doubt where it stands. Last year, the ATF spelled out the marijuana prohibition in boldface type on gun purchase forms.

“Any person who uses or is addicted to marijuana, regardless of whether his or her state has passed legislation authorizing marijuana use for medical purposes … is prohibited by federal law from possessing firearms or ammunition,” ATF spokeswoman Janice L. Kemp said.

The gun-ownership ban has withstood at least one legal challenge. An appeals court in San Francisco, rejecting a challenge on Second Amendment grounds, said in 2016 that Congress reasonably concluded marijuana and other drugs raise the risk of unpredictable behavior.
