In the midst of a drug epidemic, a KING 5 Investigation exposed misconduct at a string of state-licensed alcohol and drug treatment clinics.

Counselors were accused of soliciting cash bribes from addicted clients and falsifying attendance records and drug test results that they submit to local courts. The investigation also revealed serious shortcomings in the state agency that licenses and inspects Washington’s 570 licensed treatment centers.

The investigation started with a cluster of troubled clinics in Pierce County, but KING 5 learned it is a statewide problem, also affecting a treatment center in Spokane.
