The number of Americans who view smoking cigarettes as being bad for your health has gone down, according to a new report. The perception by teenagers and young adults that heavy cigarette smoking is a high-risk activity has declined in many states, the study on substance abuse and mental health released today found. The perceived risks of smoking one or more packs of cigarettes a day dropped between 2007-2008 and 2008-2009 in 14 states among youths aged 12 to 17, and in 31 states among those aged 18 to 25. Perceived smoking risks also dropped in nine states among those 26 and older, said the Substance Abuse and Mental Health Services Administration. Mail Online
