NEW YORK — Marijuana use is becoming more accepted among U.S. adults as states loosen pot laws, new national survey data shows.

More are using marijuana, using it more often and far fewer think it’s risky, the government survey found.

That’s understandable, experts say, as dozens of states now allow medical marijuana and four states have recently legalized pot for recreational use.

More than a half-million U.S. adults participated in the survey over a dozen years, and the responses show a shift in attitude.

Only a third of adults in 2014 said they thought weekly marijuana use was dangerous, down from half of adults in 2002.
