A judge in the Netherlands is due to decide whether foreign tourists should be banned from entering cannabis cafes.

荷兰一位法官正在裁决是否禁止外国游客进入咖啡馆。

While soft drugs are tolerated, there is growing concern at tourists visiting just for drugs, and foreign dealers¹ selling illegally at home.

The ban is due to start in three southern provinces next month, with a nationwide one by the end of the year.

A group of cafe owners are arguing at The Hague district court that the ban is discriminatory against foreigners.

If the measure is approved Dutch residents will still be allowed into the cafes, as long as they have valid² identification, or possibly hold a new "weed pass" which is also being debated.

Michael Veling, a spokesman for the Dutch Cannabis Retailers³ Association, is among those challenging the plan.

"It is going to cost me 90% of my turnover," he told the BBC World Service. "That is a very good reason for anyone to oppose any plan. Second it puts our customers in a very difficult spot, because why do you have to register to buy a substance that is still illegal?"

There are about 700 coffee shops, as they are called, in the Netherlands. The cultivation⁴ and sale of soft drugs through them is decriminalised, although not legal; police generally tolerate possession of up to five grams of cannabis.

Tougher approach

The BBC's Anna Holligan in The Hague says the nationwide ban is being strongly opposed by the Mayor of Amsterdam because around a third of the city's tourists visit to smoke cannabis in the cafes.

If the coffee shop owners lose their case they say they will take it to the European Court of Human Rights, on the grounds that the Dutch should not be allowed to discriminate⁵ against people on the basis of where they live.

The moves are part of a tougher approach to drugs introduced by the coalition⁶ Conservative-led government elected 18 months ago.

In October strong cannabis was reclassified as a hard drug, amid concerns that it has a psychotic（精神病的） effect on some users.

The move forced cannabis coffee shops to remove the more popular stronger varieties from their shelves.

In November the city of Maastricht brought in a coffee shop ban for foreign tourists from all countries, except Belgium and Germany, from where the majority of foreign customers come.
