If you’re a smoker, a new study should alarm you — big time.

The study, published in the journal BMC Public Health, found that there are some 4,800 chemicals in cigarette smoke — many of them being carcinogens — but most people who are smokers have no clue what they’re inhaling, according to a Biomed Central statement.

The study argues that more information should be available to consumers about what’s in cigarette smoke to help them understand the true dangers of smoking. However, right now that’s not available to people, which is a big concern to health officials.

You’d assume that most people already know the risks of smoking at this point, but the study reveals that young adults and smokers are actually very interested in finding out this information, but say more often than any other group that they had looked for such information and had been unable to find it.

Scientists based their finding on a national telephone survey that included about 5,000 adults over the age of 18, focusing on low-income areas which sees higher tobaccu use rates. A total of 27.5 percent of adults had look for tobacco smoke info, expecially for chemicals likely to cause cancer and other health problems. The largest percentage, 37.2 percent, were young adults between 18 and 25 years of age, and another large percentage, 34.3 percent, were smokers.

“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 because they will be better informed about the toxic chemicals present in tobacco products,” Marcella Boynton, first author of the research paper from the University of North Carolina at Chapel Hill, said in the statement.

The statement added: “Given the FDA’s role of communicating the harms of tobacco use, the researchers sought to understand how tobacco product users and non-users perceive the credibility of the FDA. Participants were asked if they had ever heard of the FDA and if they believed that the FDA could effectively regulate tobacco products. The vast majority of US adults surveyed (94.6%) reported having heard of the FDA, but awareness was lower amongst young adults, those with lower education, low numeracy and those living in poverty. The majority of both smokers (66.6%) and non-smokers (65.0%) believed that the FDA could effectively regulate tobacco products.”
