Do you have any idea what ‘ingredients’ go into making cigarettes? You would be surprised to hear what things people inhale with each puff of a cigarette – besides nicotine, I mean.
There are about 4,800 chemicals in a cigarette, many of which are carcinogenic; but researchers from the University of North Carolina, Chapel Hill, found that the majority of smokers don’t know what they’re inhaling.
Marcella Boynton, lead author of the study, said in a press release:
“The majority of the [United States] public wants easy access to information about chemicals in cigarettes and other tobacco products. Surprisingly, our results reveal that groups one might presume to be the least psychologically motivated to look for this information, young adults and smokers, were more likely to say that they had previously looked for this information.”
For the study, data was analyzed from 5,014 American adults over age 18 who were contacted in a national telephone survey. The survey focused mainly on low-income areas, which are more likely to include people who use tobacco and suffer smoking-related health problems – the impoverished, the lesser educated, and sexual minorities.
The team found that 27.5% of the respondents had sought information about the chemicals in tobacco smoke that can cause cancer and other adverse health effects.
Of the participants who had searched for information, 37.2% were between the ages of 18 and 25 – the largest percentage – and 34.3% of them were smokers. Some 26% of those who were non-smokers also said they had looked for information on cigarette smoke.
The biggest finding was that most of the participants didn’t know what’s contained in cigarette smoke, and half of them said they’d like to see that information printed on cigarette packages.
Cigarette smoke contains arsenic, ammonia, acetaldehyde, coumarin, and various other substances, most of which are known to be toxic when inhaled or ingested. The FDA lists the known toxins on the agency’s website.
However, none of this information is available to the average person who buys a pack of cigarettes. Instead, the Surgeon General provides rather vague warnings on cigarette packs about the dangers of smoking.
And since there’s such a vast number of chemicals in cigarette smoke, it’s impossible to gauge just how many health problems are caused by smoking, or how serious they are. 
“By making tobacco chemical information available to the public and tobacco industry practice more transparent, those seeking this information may be less likely to start smoking and more likely to quit…”
The researchers found a nugget of good news, however; more than 80% of smokers interviewed for the survey expressed a desire to kick the habit. 
The study was published in BMC Public Health.
