The War on Drugs was lost. The prohibition by pricing of tobacco has handed billions of dollars to organized crime.The tobacco black market is booming thanks to incredible retail prices. So even the basic idea of higher prices obviously isn't working the way they thought it would.The type of enforcement is the same as for illegal drugs. Busts, shipments seized, and so on, and the tobacco supply obviously isn't even dented. For example - Traditionally tobacco was cured with plain old sugar, which burns much hotter than just about anything else.
