In celebration (or dread) of the coming tax deadline, CNN.com reveals some of the country’s strangest state taxes. Special attention is given to a North Carolina tax on illegal substances:

“Don’t worry that you might get in trouble for admitting you have enough drugs to fuel a rave party for years. You needn’t provide any identification to get the stamps and it’s illegal for revenue employees to rat you out.

“Still, according to North Carolina’s department charged with collecting the unauthorized substance tax, only 77 folks have voluntarily come forward since 1990. Most of them are thought to be stamp collectors. (Or perhaps they were just high?)

“The majority of the $78.3 million the state has collected thus far has come from those who got busted and were found without stamps.

“But even if they had had stamps, it’s not like their legal troubles would be over. ‘Purchasing stamps only fulfills your civil unauthorized substance tax obligation,’ according to the N.C. DOR Web site.”
