Cigars, Pipes Tied To Same Risks As Cigarettes

Traditionally, doctors have asked just whether people smoked cigarettes, but they should instead be questioning patients more broadly about tobacco use

  • Cigarettes are not the only tobacco products which can cause death
  • Other tobacco products like cigars and pipes are just harmful
  • All these tobacco products can cause cancer

Cigarettes are not the only type of tobacco products that can lead to premature death or fatalities from smoking-related cancers, a U.S. study confirms.

While people who exclusively smoke cigarettes have twice the risk of premature death from all causes compared to people who avoid tobacco altogether, exclusive cigar smokers have a 20 percent higher risk of early death, researchers report in JAMA Internal Medicine.

When it comes to fatalities from specific cancers that have been tied to tobacco use, cigarette smokers have four times the risk of people who never used tobacco, but cigar smokers are 61 percent more likely to die of these cancers and pipe users have 58 percent higher odds.

“We knew exclusive users of cigars and pipes were at greater risk of disease than people who do not use tobacco,” said lead study author Carol Christensen of the U.S. Food and Drug Administration’s Center for Tobacco Products. “However, this study provides information that reflects today’s patterns of tobacco use.”

These data “underscore the importance of complete quitting,” Christensen said by email.

For the study, researchers examined nationally representative survey data, collected starting in 1985, from 357,420 participants who were followed through 2011.

Overall, 203,071 people, or about 57 percent, never used tobacco at all. Another 57,251 participants were current daily cigarette smokers, while 9,414 said they had a less frequent habit and 77,773 were former cigarette smokers.

In addition, 531 people were current daily cigar smokers, while 608 individuals used cigars less frequently and 2,398 had quit.

For pipes, 1,099 participants had a current daily habit, while 78 people used pipes less often and 5,237 had quit.

During the study period, 51,150 people died of all causes.

With a daily cigarette, cigar or pipe habit, people had an elevated risk of death from tobacco-related cancers including malignancies of the bladder, oesophagus, larynx, lung, mouth and throat, and pancreas.

Nondaily users

Even with a nondaily cigarette habit, people were more than six times more likely to die of lung cancer than individuals who never used tobacco. They also had more than seven times the risk of dying from a chronic obstructive pulmonary disease, more than four times the odds of death from oral cancers, and 43 percent higher odds of death from a circulatory system disorder.

Current cigar smokers had more than three times the odds of dying of lung cancer, and for current pipe smokers, the risk was 51 percent higher, compared with never-smokers.

The results were limited, however, by the relatively small numbers of cigar and pipe smokers in the sample, the authors noted.

Cigarettes, hookah, pipes, cigars all are equally harmful.

Another limitation was that survey questions about tobacco use changed over time and didn’t determine how often nondaily smokers might have used cigarettes, cigars or pipes.

Even so, the results suggest that doctors may need to broaden how they discuss smoking with patients to make sure people understand they’re at risk even when they don’t have a daily habit, said Dr. Michael Ong of the University of California-Los Angeles and VA Greater Los Angeles Healthcare System.

“Patients often do not associate the occasional use of cigar or pipes with health risks, but this study shows that current, particularly daily, cigar use is associated with increased overall risk of death,” Ong, who wasn’t involved in the study, said by email.

Doctors also need to broaden their message about smoking and cigarettes to include other tobacco products that are becoming more popular, said Judith Prochaska, a researcher at Stanford University in California who wasn’t involved in the study.

Traditionally, doctors have asked just whether people smoked cigarettes, but they should instead be questioning patients more broadly about tobacco use, Prochaska said by email.

“The tobacco landscape has been changing dramatically,” Prochaska added. “While cigarettes remain the primary tobacco product used, cigars, smokeless tobacco, e-cigarettes, hookah, and even pipe tobacco have seen gains in use, while cigarette use in the U.S. has been declining.” VOA

E-cigarettes May Not Stain Teeth, says Study

Conversely, exposure to vapour from the e-cigarettes or tobacco heating products resulted in little or no colour change that was comparable to the untreated controls

E-cigarettes and tobacco heating products cause significantly less staining to teeth than conventional cigarettes, a new study has found.

While cigarette smoke caused significant enamel discolouration, vapour from the e-cigarettes and aerosol from the tobacco heating products caused only minimal staining.

These next generation products do not involve combustion; the vapour and aerosol they produce are less complex and contain significantly lower levels of certain toxicants compared to cigarette smoke.

“Many studies have postulated that it is the tar in cigarette smoke that stains teeth,” said Annette Dalrymple, senior scientist at British American Tobacco in the UK.

“The study clearly shows that the e-cigarettes and tobacco heating products assessed caused minimal discolouration — very promising for consumers. However, further studies are required to understand the long-term effect on teeth staining and oral health when smokers switch to using next generation products,” Dalrymple added.

For the study, published in the journal American Journal of Dentistry, the team assessed and compared an e-cigarette, a tobacco heating product and a conventional cigarette for their impact on teeth enamel staining.

They assessed in the laboratory the level of enamel discoloration by cigarette smoke and vapour from e-cigarettes and tobacco heating products.

Tests were carried out on enamel blocks cut from bovine incisors — substitute for human teeth in dental research.

The enamel blocks were exposed to the particulate matter (isolated from the smoke/vapour) for 14 days and then whole smoke/vapour for five days.

The enamel samples were assessed before, during and after treatment and colour readings were determined using an established method involving spectrophotometer and trained scientists.

Discolouration of enamel blocks exposed to cigarette smoke was apparent in as little as one day and continued to increase as the concentration of cigarette smoke increased, the findings revealed.

Conversely, exposure to vapour from the e-cigarettes or tobacco heating products resulted in little or no colour change that was comparable to the untreated controls. (IANS)
