Enforcement of mental health care coverage lacking

It has been eight years since Congress passed a law requiring health insurers to provide Americans suffering from mental illness or substance abuse disorders with coverage for treatment that's comparable to what they would get if they were physically sick.
So far, that promise has largely not been met, many mental health advocates say. And, at a time the nation is facing an addiction epidemic, millions of people who suffer from mental illness or addiction are not getting the treatment they need as a result.
