LARAMIE, Wyo. (AP) — A new survey finds that Wyoming residents have steadily changing opinions regarding the use and possession of marijuana.

The Wyoming Survey and Analysis Center at the University of Wyoming conducted the survey Oct. 9-19, collecting 607 responses from randomly selected state citizens.

It found that 49 percent of Wyoming residents say they support allowing adults in Wyoming to legally possess marijuana for personal use. Support for marijuana use has been increasing since 2014.

At the same time, 86 percent of Wyoming residents say they support the legalization of marijuana for medical purposes if a doctor prescribes it.

And 69 percent believe that people convicted of possessing small amounts of marijuana should not serve time in jail.

The poll has a margin of error of plus or minus 4 percentage points.
