CONCORD, N.H. (AP) - As New Hampshire lawmakers consider a bill that would legalize up to an ounce of marijuana for adults, the state Health Department is drawing attention to research showing high marijuana use among 12-to-17-year-olds.

The information - based on the 2012 National Survey on Drug Use and Health - shows that about one in 10 adolescents in New Hampshire report regular use of marijuana, the ninth highest in the country. The state rate for 18-to-25-year-olds is the fifth highest in the country.

The study says the percentage of those who perceived great risk in using marijuana at least once a month is lower than national and regional averages.

It also says in 2012, 80 percent of 12-to-17-year-olds who entered state-funded treatment facilities sought treatment for marijuana dependence.
