Creates the joint legislative task force on problem gambling (task force).

Requires the task force to review findings from a problem gambling study funded in the 2018 supplemental operating budget, to review existing problem gambling programs and services in Washington state and nationally, and to review the emerging nexus between video-game addiction and casino-gambling addiction.

Requires the task force to make recommendations to the legislature, including whether additional prevalence research is needed, whether current state policies and resources meet current and projected future demand for services, and whether funding for prevention and treatment should be expanded.
