This week on Sound Effect, we share stories of the opioid crisis in the Northwest – the people who are affected, and those who are confronting it. We start by learning some of the brain science behind addiction , and why it can be so hard to kick the habit. We meet a woman who battled heroin addiction, got clean for 17 years, and then relapsed again. We head to Everett where librarians are learning to become first responders. Also in Everett, we learn about a scholarship program created to help people get into rehabilitation. We end the show by heading to Vancouver, British Columbia where drug users have taken it upon themselves to stem the tide of overdose deaths. "Sound Effect" is your weekly tour of ideas, inspired by the place we live. The show is hosted by 88.5's Gabriel Spitzer.
