Coffeeshop owners who participated in the survey say that there is hardly any kind of inspection of the so-called I-criterion (criterion residents), which implies that selling weed is permitted only to residents of the Netherlands.
Of all the coffeeshop owners outside Limburg, Brabant and Zeeland - further away from the border, 92 percent claims not to be inspected by the local authorities. In the southern provinces, it's only 8 percent. Much of the coffeeshops (78 percent) has never been checked for sale to tourists (97 percent above major rivers, 35 percent in southern provinces). Except for in Maastricht and Tilburg, there is no violation established anywhere, ever.
Coffeeshop owners report that the number of illegal street dealers has increased since the introduction of the residence criterion in their eyes has increased (41 percent), particularly in the southern provinces (76 percent).
After the introduction of the weed-pass in the south of the Netherlands, coffeeshop owners in that area see their number of visitors decrease, even in shops where tourists never came for drugs. Many Dutch buyers do not come to the coffeeshop anymore and found refuge on the illicit market.
Coffeeshop owners of some parts in Holland report that in their town there's is a big difference between the formal position of the local authorities and the actual enforcement. It happens that shop owners receive a letter that the so-called I-criterion is maintained, but informally asked to ignore the measure for fear of illegal street dealers on every street conrner.
A total of 111 coffeeshops, from 33 towns responded to the survey, including the four major cities, Amsterdam, Rotterdam, Utrecht and Den Haag. The 33 cities represent 478 coffee shops. In the Netherlands there is a total of about 650 coffeeshops.
