Although Holland is famous for tolerating the sale of small amounts of marijuana and hashish in coffee shops, both are technically illegal and the government prosecutes possession of more than several grams.

"We're saying, stop the war on drugs, which costs a fortune and there are no results," Koster said.

Koster said public prosecutors usually ignore the sale of marijuana seeds and had not contacted the magazine about the stunt. But several major supermarket chains either removed the seeds or kept the issue off the shelves.

He said the seeds were "OK" in quality.

"We had an expert test them, and he said they were a 4 out of 5," Koster said.
