When someone says "museum" in DC, you usually balk at the word and avoid the National Mall, right? Well, what if there was a museum dedicated to drugs, drug abuse, and drug law enforcement tucked away across the river? The Drug Enforcement Agency Museum recently renovated and updated EVERYTHING. Learn about opium dens, patent medicines that contained something illegal, the history of heroin and jazz, Pablo Escobar and the Colombian cartels, post 9-11 narco-terrorism, '70s DC head shops, and more. Also, check out actual bundles of pot that fell from the sky over San Diego from a plane traveling from Mexico (pictured). The museum is open Tues-Fri from 10am-4pm.
