Colorado, Washington first states to legalize recreational pot
Colorado and Washington became the first U.S. states to legalize the possession and sale of marijuana for recreational use on Tuesday in defiance of federal law, setting the stage for a possible showdown with the Obama administration.
In a 2010 study, Miron, a senior lecturer in economics at Harvard and a senior fellow at the libertarian Cato Institute, said legalizing marijuana nationwide would save about $8.7 billion a year in law-enforcement costs.
What are those costs? About 750,000 people are arrested nationwide for marijuana possession annually. Those arrests -- and expenses related to them -- could vanish. Ditto for jail time. So could the time spent on most court cases involving marijuana, Miron says.
Chopping costs is only part of the equation, though. Harvard's Miron also estimates that state, local and federal governments could collect about $8.7 billion annually in revenue if marijuana was "taxed at rates comparable to those on alcohol and tobacco."
