Attorney General Jeff Sessions sent the country into a tizzy not long ago, when he declared that the federal government would start cracking down on state-legal marijuana. This is problematic, but it's a symptom of a larger problem. Article I, Section 8, of the US Constitution lists the things that the federal government may concern itself with. Marijuana — indeed, any drug — is not on that list. In fact, a great many things that the federal government concerns itself with are not on that list. So how did we get to the point of having federal laws and regulations about marijuana and a number of other things? We had to have a Constitutional amendment to ban alcohol, so why doesn't the government need one to ban marijuana? James Harrigan and Antony Davies discuss this and more on this week's episode of Words and Numbers.
