The liberal drug policy of the authorities in the Netherlands especially led to problems in "border hot spots" that attracted "drug tourism" as well as trafficking and related law enforcement problems in towns like Enschede in the East and Terneuzen, Venlo, Maastricht and Heerlen in the South. 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. By allowing possession and retail sales of cannabis, but not cultivation or wholesale, the government creates numerous problems of crime and public safety, he alleges, and therefore he would like to switch to either legalising and regulating production, or to the full repression that his party (CDA) officially advocates. The latter suggestion has widely been interpreted as rhetorical. Leers's comments have garnered support from other local authorities and put the cultivation issue back on the agenda.
