The stigma around misuse, addiction, and recovery are barriers to prevention and treatment. iHeartRadio’s new podcast Talk to Me will be a 6-10–episode series, in partnership with the National Opioid Action Coalition, that aims to reduce that stigma and open conversations.

Interviewees include Surgeon General Dr. Jerome Adams, musician Nikki Sixx, former NFL player Randy Grimes, comedian Merf Meyer, SpiritWorks Foundation Executive Director Jan Brown, CDC Di The Best of Stuff iHeartPodcasts We could all use a little positivity right now.
