A nationwide ban on smoking tobacco in enclosed places began here Tuesday, but Dutch cafes and restaurants will permit patrons to smoke marijuana inside their premises.

Some 200 inspectors of the Food and Consumer Product Safety Authority will ensure compliance to the ban by cafes across the country. The inspectors have been trained to detect tobacco and marijuana, which is allowed in licensed coffee shops.

Violators of the smoking ban will be fined $3,800.

Meanwhile, a group of small coffee shop operators asked a court here on Tuesday to exempt them from the ban, which was imposed to promote public health.
