America's relationship with pot today is a lot like it was with alcohol at the end of Prohibition: Awkward, and enshrined in a patchwork of changing laws that contradict each other. At the federal level, pot is illegal and a major focus of the War on Drugs. At the same time, states and cities across the U.S. are making it legal for medical use, and increasingly, for recreational use as well. Denver did that two years ago, and much has changed in that city as a result. Wes looks at what Baltimore (where the drug is still mostly illegal) can learn from Denver's path to marijuana legalization.
