These Toking signs are present in Amsterdam coffee shops where you are allowed to smoke cannabis.
In February 2006, the City of Amsterdam put up No Toking signs in De Baarsjes, one of the cities poorer neighbourhoods. The idea was to discourage youths from loitering and getting high in the street where they would undoubtedly cause untold amounts of trouble and mayhem. The signs didn?t last very long.
In fact, so many went missing (the first and second ones going the very same evening they were put up), that the cities authorities soon realised they had stumbled upon some gold-dust and actually began selling them to tourists and people who had seen them. Now they are available in these large and small size stickers and make an interesting decoration for any boudoir, digs, guitar amp, car or anything else you might like to stick them on.
The Toking Allowed sign features a lit joint in a blue square with a stream of smoke marked by trailing cannabis leaves.
