Non-Smokers too at Risk From Second-Hand Smoke

A ban on smoking in public places came into effect across India eight years ago — but India still remains home to 12 per cent of the worlds smokers and they with their second-hand smoke pose a threat to those who don’t smoke. Healthy non-smokers exposed to second-hand tobacco smoke are at an increased risk of developing coronary atherosclerosis, warns a senior cardiologist here, citing earlier findings which new studies have bolstered. Investigators have observed a dose-response relationship between second-hand smoke exposure and atherosclerosis as documented by CT angiography, said…

Unknown Exposure To Second-Hand Smoke May Cause Early Death

US researchers have identified a new biomarker which revealed that known and unknown exposure to second-hand smoke may lead to an increased risk of mortality in non-smokers. Serum cotinine — a metabolite of nicotine — when used as a biological marker of exposure to second-hand smoke was found to have associations to overall and cause-specific mortality in non-smokers. Increased levels of serum cotinine in blood were significantly also associated with all types of cancers, and heart disease, the researchers said. “The study found that non-smokers are exposed to second-hand smoke…

Second-hand smoke can hurt kids years after exposure

Second-hand smoke can hurt kids years after exposure

Breathing second-hand smoke during childhood can lead to long-term breathing and health problems and a shorter life expectancy, according to a new scientific statement from the American Heart Association. Even though the harms of exposing kids to cigarette smoke are well known – asthma and lung infections among them – many children still breathe this smoke at home or in public places or while riding in cars or buses, noted Dr. Geetha Raghuver, lead author of the statement. “Minority children and those from poor backgrounds are exposed more often,” Raghuver…
