Seattle : Puffing on a cigarette is a bit like inhaling from the back end of a cow, or being poisoned like a rat, according to a new ad campaign sponsored by Washington state health officials. Cigarette smoke contains methane, a noxious gas “which just happens to be the main ingredient in cow farts,” and arsenic, “the stuff they use to kill rats,” according to radio ads run by the Washington State Department of health. |
