A new study from the David Geffen School of Medicine at UCLA suggests that increasing cigarette taxes could be an effective way to reduce smoking among individuals with alcohol, drug or mental disorders.

The study, published online in the American Journal of Public Health, found that a 10 percent increase in cigarette pricing resulted in an 18.2 percent decline in smoking among people in these groups.

The findings demonstrate that increasing cigarette taxes could be a way to curb smoking, which is still the leading preventable cause of death in the United States, according to the study’s lead author, Dr. Michael Ong, an assistant professor of medicine in the division of general internal medicine and health services research at the Geffen School of Medicine.

“Whatever we can do to reduce smoking is critical to the health of the U.S.,” said Ong, who is also a researcher at UCLA’s Jonsson Cancer Center. “Cigarette taxes are used as a key policy instrument to get people to quit smoking, so understanding whether people will really quit is important. Individuals with alcohol, drug or mental disorders comprise 40 percent of remaining smokers, and there is little literature on how to help these people quit smoking.”
