The Iowa House voted to ban the sale of so-called e-cigarettes to minors this week. Electronic cigarettes heat liquid and nicotine into a smokeless vapor. Republicans, who control the House, blocked debate on a Democratic amendment that would have also kept similar e-cigarettes out of kids’ hands, even if they do not contain nicotine. Iowa Public Radio’s Clay Masters talks to the sponsor, Rep. Tyler Olson (D - Cedar Rapids) of the amendment and takes a trip to an e-cigarette shop in northwest Des Moines.
