E-cigarettes: Hazardous or helpful?
E-cigarettes: Hazardous or helpful? Their efficacy as a tool for quitting regular cigarettes and their long-term safety remain concerning. Even if you never touch cigarettes, you probably know someone who does (or did) smoke. Nearly half of Americans smoked in the mid-1960s, compared with just 14% today. Still, cigarette smoking is responsible for nearly one in five deaths in the United States, and about one-third of those are due to heart disease.
