WASHINGTON - More than half of Americans favor legalizing marijuana, and support has grown among the young and the old, according to a national poll out Thursday.
The Pew Research Center said it found that 52 percent of adults believe the government should allow people to use pot -- the first time in four decades that a majority of Americans have held that view.
Forty-five percent oppose legalization.
The survey showed that 65 percent of people born since 1980 support legalization, up from 36 percent seven years ago. Half of the Baby Boomers - those born between 1946 and 1964 - also favor legalization, up from 17 percent in 1990, according to Pew.
Researchers polled 1,501 adults between March 13 and March 17, and the margin of error is 2.9 percentage points.
California, Colorado, Oregon and 15 other states allow marijuana use for medical purposes. Last fall, voters in Colorado and Washington state took the unprecedented step of allowing the recreational use of pot.
Ten U.S. House members, led by Democrats Earl Blumenauer of Oregon and Jared Polis of Colorado, are working to overturn the 43-year-old federal ban on pot. But their bills aren't expected to pass.
