Until recently, legal highs were a mysterious word to most people. We didn't really know what they were or how they worked. We did not identify them as something dangerous and life-threatening. Until 2010, they were widely available in special shops in every city in Poland (so-called smartshops, cofeshops). As a "collector's item", a new and legal way of improving mood, they quickly became a popular stimulant, especially among young people.
