In 2006, Gerd Leers, then mayor of the border city of Maastricht, on the Dutch-Belgian border, criticised the current policy as inconsistent, by recording a song with the Dutch punk rock band De Heideroosjes.
He also made tour documentaries of the Dutch Punk group Heideroosjes.
It was a reply to a song by Gerd Leers, Mayor of Maastricht, (with punk band Heideroosjes), which called for a more progressive policy which would not only regulate the selling of soft drugs, but also legalise their production.
