Yes, it is and it's getting bigger. The punitive cigarette taxes have created a new black market at the same time the above ground economy is in the tank.
I have collected dozens of stories of cigarette black marketing being used to fund terrorism. It is much harder to catch the black marketeers because they are after all dealing in a legal product. The crime of evading state cigarette taxes fills the nitch between high risk selling of street drugs, and low risk legal retailing. The tobacco nazis have created another monster.
To report stolen, hijacked, or siezed cigarettes call the ATF at 1-800-659-6342.
