While the nation's collective attention was on the presidential race, one issue that appeared on five state ballots was quietly approved by voters: legalized marijuana. Voters in Arizona, New Jersey, Montana and South Dakota approved the legalization of recreational weed, while South Dakota also joined Mississippi in legalizing medical marijuana. There are now 16 states in which recreational marijuana is legal. The others are Alaska, California, Illinois, Maine, Massachusetts, Michigan, Nevada, Oregon, Vermont, Washington state and Colorado. Speaking of Colorado, voters there took their acceptance of drug use one step further on Tuesday -- they approved the legalization of magic mushrooms and Oregon decriminalized all drugs. Is it time for Tennessee to consider legalizing marijuana?
