Passage: ST. LOUIS (KPLR) - A new smart phone app aimed at helping recovering heroin addicts is now available.
Heroin use among young adults 18 to 25 has doubled in the last decade, according to the CDC. Many people in that age group have a smart phone.
The app is called the Squirrel Smart Addiction App. It allows recovering addicts to set up a 10-person support team.
The app, which is free to download, has users rate their stress level throughout the day and shares the information with the team. It also features a one-touch panic button that alerts the entire support team. It also tracks and rewards sobriety.
The Ohio State University Wexner Medical Center is behind the app.
“I think the younger generation will use it,” Baxter said.
“Any tool that will help is great,” she said.
Vigna, who lost a daughter to heroin overdose, works to raise awareness about the drug in the St. Louis region.
Vigna is leading a walk to raise awareness in Warrenton on July 11.
It starts at noon and is open to the public.
The walkers are meeting at Jordan’s Place. It’s located at 202 E. Main St.
You can download the app at the Google Play store.
