Giving up menthol ciggies may be harder for some smokers

WASHINGTON - A new study has suggested that menthol cigarettes may be harder to quit, particularly for some teens and African-Americans, who have the highest menthol cigarette use.
One possible reason suggested in the report is that the menthol effect is influenced by economic factors - less affluent smokers are more affected by price increases, forcing them to consume fewer cigarettes per day.
“This pattern of results is consistent with an effect that relies on menthol to facilitate increased nicotine intake from fewer cigarettes where economic pressures restrict the number of cigarettes smokers can afford to purchase,” said Jonathan Foulds, professor, Public Health Sciences, Penn State College of Medicine, and an author of the report.
Menthol is a compound extracted from mint oils or produced synthetically that activates cold-sensitive neurons in the nervous system. Menthol cigarettes make up about 25 percent of the market but are preferred by certain subgroups of smokers, including about half of teenage smokers and 80 percent of African-American smokers.
Research has shown that menthol cigarettes may provide higher levels of carbon monoxide, nicotine and cotinine per cigarette smoked than regular cigarettes.
“Menthol stimulates cold receptors, so it produces a cooling sensation,” Foulds said.
“This effect may help smokers inhale more nicotine per cigarette and so become more addicted. In effect it helps the poison go down easier.
“The smoker who has reduced their cigarette consumption typically compensates by increasing inhalation per cigarette. Menthol in cigarettes makes the smoke less harsh, enabling these smokers to obtain a larger and more reinforcing nicotine hit.”
The researchers reviewed the evidence from 10 published studies that compared smoking cessation rates or proportions between mentholated and regular cigarette smokers.
The study has been published in the journal Nicotine and Tobacco Research. (ANI)
