This video, which was released last year, was produced by the city of Amsterdam to warn tourists that heroin was being sold by street dealers as cocaine. The city set up signs and offered inexpensive drug test kits so people could test the street drugs they’d purchased and find out if it contained heroin. The video ends with the promise that drug users will not be arrested for using drugs or for reporting the discovery of white heroin, or for seeking medical help in an emergency. Could you imagine something this sensible happening in the U.S.?
