Cannabis in the Netherlands is illegal, but is decriminalised for personal use. Recreational consumption of the drug is tolerated, and it is available in coffeeshops.
[..]Cannabis has been available for recreational use in coffee shops since 1976. Cannabis products are only sold openly in certain local "coffeeshops" and possession of up to 5 grams for personal use is decriminalised, however, the police may still confiscate it, which often happens in car checks near the border. Other types of sales and transportation are not permitted, although the general approach toward cannabis was lenient even before official decriminalisation.
Though retail sales are tolerated, production, transportation, and bulk possession of marijuana outside of retail stores is illegal, preventing testing for contaminants and dosing. After legalization and regulation of the entire supply chain in other countries, some cities in the Netherlands are participating in a pilot project using officially approved growers and testers, and labeling of the amount of THC.[..]
It is a criminal offence in the Netherlands to possess, produce or deal in drugs. This applies to soft drugs as well as hard drugs. The use of drugs by persons aged 18 years or older is not a criminal offence in the Netherlands. But to prevent nuisance, municipal authorities may include a provision in their general municipal bye-laws prohibiting drug use in designated areas. If you use soft drugs in one of these designated areas, you may be arrested or ordered to pay a fine.
vannak szabályaik, csak -érdemben- nem tartatják be őket.
