Many people don’t know what makes smoking dangerous

Many people don’t know what makes smoking dangerous

Most Americans don't grasp that the chemicals produced by burning a cigarette are more harmful than the manufacturer's additives that cigarette also contains, and many mistakenly believe filters can protect them from breathing toxic fumes, a recent study suggested.

"We already knew that many people, especially smokers, think smoking might be dangerous for other people but not for themselves," said lead study author Dr. Noel Brewer, a public health researcher at the University of North Carolina in Chapel Hill, reported Reuters.

"All cigarettes create smoke that has toxic and deadly chemicals," Dr. Brewer added by email. "Additives don't change tobacco smoke and make it dangerous — tobacco is inherently dangerous."

To see how the general public perceives the harms associated with smoking, researchers examined data from three surveys done online and by phone that included a total of more than 9,000 adults and 1,000 teens.

Among other things, respondents were asked if they had ever heard of 24 different chemicals found in tobacco smoke; how harmful they considered them to be; and how much the presence of a particular substance would prompt them to quit smoking.

Among adults, 61 percent surveyed by phone and 72 percent quizzed online mistakenly thought most of the toxins in cigarettes came from chemicals added by manufacturers to enhance the flavor or performance of the products, the study found.

Just 31 percent of adults contacted by phone and 24 percent surveyed online correctly believed harmful toxins in smoke come from the act of burning a cigarette or even tobacco alone, researchers report December 6 in Tobacco Control.

Smokers were more likely to have the facts wrong than non-smokers.

Teens were evenly split on the perceived source of harmful substances, with 43 percent opting for additives and 46 percent for the burning of the cigarette itself. For adolescents, there wasn't much difference in their perceptions based on whether or not they actually smoked themselves.

Up to about one in three adults and roughly one in four teens also wrongly believed that filters successfully trap harmful chemicals from cigarette smoke. Once again, this belief tended to be more common among the smokers.

Nearly all of the survey participants had heard of nicotine, and many of them were familiar with carbon monoxide. A small proportion also said they were aware of toxins in cigarette smoke such as ammonia, arsenic and formaldehyde.

But people weren't consistently aware of nitrosamines, among the most deadly chemicals produced in cigarette smoke, across the three surveys.

Respondents were more likely to say that chemicals they had heard of, and ones that started with letters rather than numbers would tempt them to quit. But this enthusiasm was more common among non-smokers than it was among smokers, and those with higher levels of literacy and numeracy.
