Cigarette smoking among American teenagers dropped to a record low in 2012, a decline that may have been partly driven by a sharp hike in the federal tobacco tax, researchers said on Wednesday.
An annual survey of about 45,000 students in the eighth, 10th and 12th grades found that the overall proportion of those saying they had smoked in the prior 30 days fell by just over a percentage point to 10.6 percent.
"A one percentage point decline may not sound like a lot, but it represents about a 9 percent reduction in a single year in the number of teens currently smoking," Lloyd Johnston, the principal investigator in the study, said in a statement.
He said reductions on that scale can translate into the prevention of thousands of premature deaths and tens of thousands of cases of cancer and other serious disease.
The researchers also cited the increase in federal cigarette taxes, raised by 62 cents a pack in 2009, as a likely contributing factor. The findings were part of an annual survey by University of Michigan researchers released by the National Institute on Drug Abuse.
Smoking rates fell for each of the individual age groups surveyed, most notably among eighth graders — from 6.1 percent in 2011 to 4.9 percent in 2012, the survey found.
