The deaths of four young people concentrated in a suburban city in such as short time has many people concerned. While parents might think of fentanyl as a big-city problem, health experts say it's something we all need to be aware of.

The Santa Rosa Police Department is urging parents to talk to their children about the dangers of fentanyl, which is often mixed with other drugs, leading to unintentional overdoses. Even as little as 2 milligrams of fentanyl can be fatal, officials warned.

Santa Rosa authorities announced that at least two teens have died and two others were hospitalized following possible fentanyl overdoses over the weekend, with police making an arrest.
