Marijuana is rapidly becoming a big, semi-legal business across the country, with $5.7 billion in sales last year and tens of thousands of people working and paying taxes as they cultivate, package and sell cannabis.
Colorado, Alaska, Oregon, Washington state and Washington, D.C. have all legalized adult recreational use, and 23 states and the District of Columbia permit some form of medical use. That’s despite the fact that marijuana remains an illegal drug and Schedule 1 controlled substance at the federal level.
