BISMARCK, N.D. (AP) - North Dakota lawmakers have questions about the cost of an anti-tobacco measure, and whether they can be forced to earmark money for it.

The Legislative Council held hearings on the potential costs of three initiatives on the Nov. 4 ballot.

The measures would spend more money on anti-tobacco efforts, cut state income taxes and change the management structure at North Dakota's workers' compensation agency.

The tobacco proposal says more money from a lawsuit settlement against the nation's largest tobacco companies should be spent to discourage smoking.

It says at least $18.6 million should be devoted to tobacco control efforts every two years.

Some lawmakers are wondering whether they have to provide the money, because the North Dakota Constitution gives them control over how state funds are spent.
