TOPEKA — An intensive look at the Kansas substance abuse disorder system reveals gaps in services that can be addressed to provide better care and support statewide, university researchers said. “But the truth is that people use a lot of things at the same time,” von Esenwein said. “In that way, substance use disorder really is a factor affecting the lives of all Kansans because those one in five are people that you know,” Hron said. A needs assessment is a comprehensive look at the substance use disorder throughout the state, von Esenwein said. Community mattersEvery community is different, and the people and systems there have different needs, Hron and von Esenwein said.
