The black market for cigarettes is alive and well in this country and has been been for decades. The legalization of marijuana and the accompanying taxes ensures that the current black market for marijuana will continue to flourish as well. Taxes on cigarettes and alcohol have always been an easy revenue source for governments, and have always gone up never down. There is nor reason to suggest that the same thing won't happen with marijuana, which simply places government in competition with the criminal element, but unwilling to compete in price.
