California's largest supermarket chain began removing cigars, pipe tobacco and chewing tobacco from shelves because the products are not labeled as cancer-causing in compliance with a state law.

Cigarettes are not involved in the action announced Tuesday by Vons Cos. Inc. because they already carry a federally mandated warning label. Several brands of chewing tobacco that carry such labels also are exempt.The law requires the state to identify products and substances than can cause cancer, birth defects and sterility. Businesses must warn the public of "significant" amounts of the substances.
