A lawsuit is challenging Wisconsin’s new law banning the sale of e-cigarettes and vaping products not approved by the Food and Drug Administration. The ban means options are limited to the 39 products currently approved by the FDA. Retailers that sell non-approved items face a fine of $1,000 per day per product. The trade group Wisconsinites For Alternatives to Smoking and Tobacco, or WiscoFAST, is suing the state.
