DENVER (AP) -- Two Western states with some of the nation's lowest smoking rates are considering cracking down even more by raising the tobacco age to 21.
Utah and Colorado lawmakers both voted favorably on proposals Thursday to treat tobacco like alcohol and take it away from 18- to 20-year-olds, a move inspired by new research on how many smokers start the habit as teenagers.
"By raising the age limit, it puts them in a situation where they're not going to pick it up until a much later age," testified Marla Brannum of Lehi, Utah, who spoke in favor of the idea there.
In Colorado, the testimony was similar -- that pushing the tobacco age could make it harder for teens to access tobacco, and possibly reduce usage rates among adults.
"What I'm hoping to do is make it harder for kids to obtain cigarettes," said Rep. Cheri Gerou, a Republican who sponsored the measure.
Both proposals face several more votes. But they're the furthest any states have gone to curb access to cigarettes by teens.
A paper published last year in the journal Annals of Internal Medicine said that 9 out of 10 daily smokers have their first cigarette by 18 years of age, and that about 90 percent of cigarettes purchased for minors are obtained by people between 18 and 20 years old.
The Washington-based Campaign For Tobacco-Free Kids advocates the higher smoking age and argues that it could make a serious dent in tobacco deaths down the road.
"We see this as sort of an added step to reducing smoking rates," in addition to higher tobacco taxes and other curbs, said Campaign vice president Peter Fisher.
Four states, including Utah, already require tobacco purchasers to be 19. The others are Alabama, Alaska and New Jersey.
Fisher said the 21-for-tobacco bills are also pending in state legislatures in Hawaii, Massachusetts and New Jersey. Maryland lawmakers considered and rejected the idea this year. New York City last year raised the tobacco age to 21, as did Hawaii County, Hawaii.
Utah already has the nation's lowest smoking rate, about 12 percent in 2011 according to the Centers for Disease Control and Prevention. Colorado isn't far behind, at about 18 percent in 2011, according to the CDC.
Despite the low rates, health advocates in both states testified that a higher tobacco age could depress the rates even further.
"Moving it to later, obviously we can help reduce use," said Bob Doyle, head of the Colorado Tobacco Education and Prevention Alliance.
