BEMMEL, Netherlands (AP) — The Netherlands expanded a government-run initiative on Monday allowing legal cannabis sales.

While growing cannabis is still illegal, cannabis shops — known as coffeeshops — in 10 municipalities will be allowed to sell marijuana from 10 licensed producers.

“Weed was sold here legally for 50 years, but the production was never legal. So it’s finally time to end that crazy, unexplainable situation and make it a legal professional sector,” Rick Bakker, commercial director at Hollandse Hoogtes, one of the regulated producers, told The Associated Press.

Some 80 coffeeshops are taking part in the experiment which advocates hope this will ultimately end a long-standing legal anomaly — you can buy and sell small amounts of weed without fear of prosecution in the Netherlands, but growing it commercially remains illegal.

Bakker's company in Bemmel, near the German border, is indistinguishable from the surrounding greenhouses producing tomatoes and peppers. But it makes 200 kilograms (440 pounds) of weed per week and is one of the largest producers in the experiment.

A trailblazer in decriminalizing pot since the 1970s, the Netherlands has grown more conservative. Amsterdam, long a magnet for marijuana smokers, has been closing coffeeshops in recent years and has banned smoking weed on some of the cobbled streets that make up its historic center.

Advocates have been pushing for a legal growing for years, citing the safety of the product as well as concerns about crime.

Benjamin Selma, the head grower at Hollandse Hoogtes who worked in cannabis production in California for more than a decade, said the quality control for the cannabis is extremely high. “We do a full test, microbial, cannabinoid, terpene, as well as yeast and anaerobic bacteria, heavy metals as well. So it’s very, very controlled,” he told the AP.

The company, which does not use pesticides and tightly regulates growing conditions, has an eye to the environment. The production facility gets its energy from solar panels and uses biodegradable packaging.

“It is also a great opportunity to see how cooperation within the closed chain between legal growers, coffeeshop owners and all other authorities involved works,” Breda Mayor Paul Depla told the AP when the first phase was launched in 2023.

The experiment "is really a political compromise,” according to Derrick Bergman, chairman of the Union for the Abolition of Cannabis Prohibition. The plan dates to 2017, when Christian political parties and pro-legalization parties agreed to a test run after a bill to decriminalize production failed.

The government will evaluate the experiment after four years.

“A research team, advised by an independent guidance and evaluation committee, is examining the effects of a controlled cannabis supply chain on crime, safety and public health,” the government said in a statement.

Selma said he is happy to be working without concerns about prosecution. “I’ve seen some bad moments,” he said, “and I don’t know if I ever believed I would be so free.”

The coffeeshops taking part in the initiative are located in Almere, Arnhem, Breda, Groningen, Heerlen, Hellevoetsluis, Maastricht, Nijmegen, Tilburg, and Zaanstad.
