The cruel nexus of mental health and mass incarceration

Hello friends,

The issues of mental health and mass incarceration are inextricably linked. Instead of providing treatment and care to many people facing mental health challenges, the nation locks them in prisons and jails. And once someone is behind bars, their mental health challenges will almost certainly get worse, while accessing care and support becomes even more difficult. It is a brutal cycle that ruins lives.

There is a ton of outstanding research [[link removed]] about the links between mass incarceration and mental health. This month, in honor of Mental Health Awareness Month, we’re highlighting a few pieces that have caught our eye because they effectively show how broken the current system is:

The Treatment Advocacy Center has an amazing report [[link removed]] (with data from all 50 states) that explains how the limited number of hospital mental health beds and the flawed system for determining who gets access to that treatment mean that most people can only access care if they end up behind bars first. The mental health harms of incarceration cannot be overstated. We pulled some of the best research available [[link removed]] that shows how being incarcerated takes a mental toll, and how that continues even after a person is released. Suicide continues to be a leading cause of death in prisons [[link removed]] and jails [[link removed]]. But new research [[link removed]] shows that the elevated risk of suicide follows someone throughout their life after incarceration. Mental health conditions are often present at the same time as substance use disorder. This recent study [[link removed]] suggests that justice-involved women, who we know have a higher likelihood of dual diagnoses, face immense physical and social barriers to getting the mental health care they need.

This only begins to scratch the surface of the damning research about mental health and mass incarceration. I encourage you to visit our full collection of research on this topic [[link removed]] to learn more.

Let’s get to this month’s updates to our Research Library. We’ve added 24 new reports focusing on crime, drug policy, felony disenfranchisement, and more.

We hope this work is useful and informative!

In most states, people incarcerated in prison must pay medical "copays" to access health care.

In this new briefing [[link removed]], we explain that policies that waive these fees are limited, inconsistent, and certainly don't fix the problems with charging incarcerated people for care.
