An indoor-smoking ban that takes effect in July in the Netherlands is aimed primarily at cigarettes but also could mean problems for the country's quasi-legal marijuana "coffee shops," Reuters reported June 9.

"Coffee shops will be treated in the same manner as other catering businesses. They will be smoke-free," said Dutch Prime Minister Jan Peter Balkenende. "It would have been wrong to move towards a smoke-free catering industry and then make an exception for coffee shops. People would not have understood that."

Under the law, shops would have to set up separate smoking rooms for smoking patrons. Marijuana cafe owners insisted that the law only applies to tobacco.
