A new study from the University of Washington has found that gun control laws restricting adults between the ages of 18 and 20 years old aren’t working to decrease homicides.

The Daily Hive reports that the five states that have passed such age restrictions are: Massachusetts, Maryland, New Jersey, New York, and Wyoming.

The authors of the study concluded, “In this difference-in-differences analysis of a national cohort, there was no statistically significant change in the rates of homicide perpetrated by young adults aged 18 to 20 in states that implemented stricter minimum age laws compared with those that did not.”

The title of the study is “Association of Minimum Age Laws for Handgun Purchase and Possession With Homicides Perpetrated by Young Adults Aged 18 to 20 Years,” and can be read in its entirety here.
