A free, self-guided GPS audio walk through the side of Czech legalization that never made the postcards. While the marches filled the squares, the actual machinery — a research institute in Josefov, a hemp pharmacy in a Wenceslas Square arcade, Žižkov's growshops and publishers, a hemp association and a state agency — did the paperwork. 6 stops beyond the tourist core, narrated by Marta. Companion walk to Prague Walk: How Cannabis Became Legal. Walk it on location with GPS, or follow along from anywhere.
