Nicotine doesn’t cause cancer, but a majority of Americans believes it does. The idea that nicotine itself is harmful probably leads the public to fear and avoid low-risk nicotine products like e-cigarettes.
A new study offers alarming evidence that Americans misunderstand the relative safety of nicotine. More than half of adults (52.9 percent) think nicotine causes most of the cancer from smoking, and another 21.2 percent weren’t sure.
Almost as many cigarette smokers — 52.5 percent — think nicotine is a carcinogen. That means they may be unlikely to use vaping products, or even nicotine replacement therapy products like gum and patches, since they may believe those products aren’t any safer than smoking.
The study reflects that concern too. Only 31.6 percent of the surveyed smokers agreed that e-cigarettes are less harmful than smoking cigarettes. And a miniscule 3.4 percent believe vapes are much less harmful. Even vapers are misinformed, although less so as a group than smokers and non-smokers. The study found that 14.6 percent of vapers believe that nicotine causes cancer.
The study comes from PinneyAssociates, a Washington, D.C.-area consulting firm. The findings were presented last month at the Society for Research on Nicotine and Tobacco (SRNT) annual meeting in Baltimore. It hasn’t yet been published. Pinney researchers analyzed data from the National Cancer Institute’s Health Information National Trends Survey to arrive at their conclusions.
“That adults’ misperceptions about the health effects of nicotine persist despite the long-term availability of FDA-approved over-the-counter nicotine replacement products is troubling and needs to be addressed with clear communications to the public — especially smokers — that nicotine is not what is causing smoking-related disease,” said lead author Karen K. Gerlach, Ph.D., in a press release.
“Leading public health experts have called for trusted authorities to communicate clearly about nicotine to smokers,” she added, “which should help them understand that there is a continuum of risk across nicotine-containing products and use that understanding to help them reduce risks to their health.”
But trusted authorities aren’t communicating the real risks of using non-combustible nicotine products. The possibility that nicotine affects adolescent brain development — based on nothing but rodent behavioral studies — is regularly trumpeted as a reason to carefully control vapor products, even by officials who are medical doctors like FDA Commissioner Scott Gottlieb.
