The Prince George’s County Council passed a local ordinance during its meeting yesterday to ban the use of electronic cigarettes in all locations where smoking is prohibited, except the MGM casino.

As reported by the Washington Post,

The MGM National Harbor casino, which is expected to open in the summer, will be the second casino in the state to allow use of electronic cigarettes. Council member Derrick Leon Davis (D-Mitchellville) first proposed the amendment during committee hearings, citing a similar provision passed by the Baltimore City Council to permit vaping at that city’s Horseshoe Casino.

Three of Maryland’s other five casinos — including Maryland Live, the biggest revenue-generator — prohibit the practice outright.

Passage of the bill has drawn criticism from anti-smoking activists. Council members have indicated that they would be open to modifying the legislation to allow vaping in designated areas instead of on the casino floor.
