California's top cop is seeking to halt the sale of one company's electronic cigarettes in the state, saying they contain dangerous chemicals and are being marketed to children.

State Attorney General Jerry Brown filed suit Wednesday in Alameda County Superior Court against Florida-based Smoking Everywhere Inc., a leading manufacturer of e-cigarettes.

Brown says the company has no evidence to back up claims their product is safe.

Smoking Everywhere's devices look like regular cigarettes but are battery-operated and contain cartridges of nicotine. A heater converts the chemical into a vapor.

The company did not immediately return a call seeking comment.

The U.S. Food and Drug Administration found last year that e-cigarettes contain carcinogens.
