A study by a nonprofit health advocacy group says youth drug overdose rates are up in Kansas, but remain lower than the national rate.

The study released Thursday by Trust for America’s Health shows that Kansas’ overall drug overdose death rate for 12- to 25-year-olds was 5.9 deaths for every 100,000 youths. That compares to 7.3 deaths nationally for every 100,000 youths.

The Wichita Eagle reports (http://bit.ly/1T3A94w) that the state’s rate quadrupled over the last 12 years. Only Wyoming had a greater increase.

The Kansas Department for Aging and Disability Services says the state waiting list of people who need funding from the state in order to receive treatment for addiction has increased over time but started spiking about three years ago.
