Could you lose your concealed carry permit because Marijuana is still considered a controlled substance under Federal law? In Michigan, the answer could be yes.
The ATF is telling firearms dealers that some Michigan concealed pistol license holders are "likely" prohibited from buying a firearm because they are Marijuana users.
The ATF made the determination that Michigan law is no longer valid with respect to Michigan CPL holders who buy guns. Why? Because Michigan legalized Marijuana, which is still a Schedule 1 Controlled Substance under Federal Law. H/T Uncle Sam's Misguided Children
