A national poll shows that a majority of Americans consider a wide range of drugs — from alcohol to heroin and cocaine — as a problem in their communities and say more needs to be done to address it.

The poll was conducted by The Associated Press-NORC Center for Public Affairs Research.

The poll found that 62 percent of Americans believe that at least one type of substance use is a serious problem in their communities. Some 43 percent say they have a relative or close friend with substance abuse issues. Seven in 10 Americans believe not enough is being done to find better addiction treatment or to make treatment programs more accessible.

The poll has a margin of error of plus or minus 3.9 percentage points.
