Nov. 5, 2009 -- Want to quit smoking? Your chances may be better if you
don't switch to a "light," "ultra-light," or "low-tar" cigarette before you
In a newly published study, smokers who traded in their so-called
"full-flavor" cigarettes for cigarettes with these labels made more attempts to
kick the habit than other smokers, but were almost half as likely to actually
Health officials have long recognized that brands labeled light,
ultra-light, mild, and low-tar are no less likely than other cigarettes to
cause smoking-related diseases like lung cancer and heart disease; that's
because people tend to smoke more of them and inhale more deeply.
But it has not been clear if making the switch to these '"light" brands had
an impact on smoking-cessation rates.
As many as 84% of the cigarettes sold in the U.S. have labeling that
suggests they are lower in tar and nicotine, according to the latest figures
from the Federal Trade Commission.
"We found that switching for any reason to a so-called lighter cigarette
appears to be associated with a lower chance of quitting, especially when
people switched with the intent of quitting smoking," study researcher Hilary
Tindle, MD, PhD, tells WebMD.
Switching to 'Light' Cigarettes
Tindle and colleagues from the University of Pittsburgh Center for Research
on Health Care analyzed data from a 2003 survey of smokers sponsored by the CDC
and the National Cancer Institute.
Their sample included roughly 31,000 smokers or former smokers.
The analysis revealed that:
- Just over 12,000 of those surveyed (38%) reported switching to a "lighter"
cigarette at some time.
- Switchers were 58% more likely to have tried to give up smoking in the year
prior to completing the survey.
- The overall odds of giving up smoking were 46% lower among those who
switched than among those who stuck with their original brands.
Smokers who switched to what they perceived as a lighter cigarette for
health reasons were the least likely to quit smoking.
Rather than helping smokers who want to kick the habit succeed, switching
may undermine their resolve by giving them a false sense that smoking is safe,
"Unfortunately, a substantial proportion of smokers and nonsmokers still
believe these cigarettes are healthier even though we have known for many years
this is not true," she says.
