Convictions for Possession of Drugs, Possession of Drug Paraphernalia, whether as an ordinance violation or crime is a basis for cancellation of your Concealed Carry (“CC”) Permit. But, simply being cited or charged without a conviction can also result in cancellation or refusal to issue a CC Permit.
Per the Wisconsin Department of Justice (“DOJ”), the agency processing CC permits), if you are arrested and booked, they will receive copies of police arrest reports from the Criminal Information Bureau (“CIB”). If the reports indicate use of illegal drugs or admissions of use, that may constitute a basis for cancelling or refusing to issue a CC permit.
This came to my attention when a caller told me he was a passenger in a car where the driver was charged and prosecuted for a drug charge. The caller was not charged; however, the DOJ nevertheless concluded from a review of the police reports that the caller met the federal definition of a user of illegal drugs and cancelled his CCW permit.
