UC HEALTH LINE: Don't Underestimate the Negative Effects—Health and Social—of Tobacco Use

CINCINNATI—Regardless of whether it is smoked, chewed or inserted next to the lower lip, tobacco is detrimental to your health. As we enter the resolution-making season, Nagla Abdel Karim, MD, encourages all tobacco users to commit to kick the habit for good. 

There is no such thing as a "safe” tobacco product, according to Karim, because they are loaded with harmful chemicals like arsenic, benzene and formaldehyde that the National Cancer Institute cites as cancer-causing agents. 

In addition to an increased risk for head, neck and lung cancers, tobacco users are at additional risk for chronic respiratory disease, cardiovascular health problems and strokes. 

"Tobacco causes increased heart rate, high blood pressure and irregular heartbeats—all of which lead to a greater risk of heart attack and stroke,” says Karim, a medical oncologist with the UC Cancer Institute and UC Health and assistant professor at the University of Cincinnati College of Medicine.

The cancer-causing agents in tobacco can also get into also the lining of the stomach and esophagus, leading to higher risk for gastrointestinal  and genitourinary cancers.

"Many people who quit smoking are surprised by how much better they feel. They experience a sense of confidence and control; they smell better and feel more relaxed. But quitting isn’t an easy feat; nicotine is addictive and the power of addiction and habitual behaviors cannot be discounted,” adds Karim. 

"The best advice is to never pick up the habit because quitting is never easy. Switching from one product—say cigarettes to spit tobacco—is really switching trading one bad habit for another.”

In 2007, the American Cancer Society published a study comparing the mortality of former cigarette smokers who substituted chewing tobacco for cigarettes with smokers who quit using tobacco entirely. After 20 years, people who had switched to chewing tobacco had a higher rate of death from lung cancer, coronary heart disease and stroke than those who quit using tobacco entirely. Karim says the large population size (116,000 men) and length of study makes this a very scientifically valid conclusion that people should take seriously. 

"If the health impact isn’t enough to motivate people to kick the habit, think about the social impact of tobacco use—chronic bad breath, unattractive yellowish-brown strains on your teeth, black-coated tongue, racking/bleeding gums, painful mouth sores and receding gums are common among tobacco users,” adds Karim.
