Even college students who are not directly suffering from opioid abuse and addiction may be caught up in secondary effects from the epidemic. A team of Penn State Lehigh Valley researchers found that about one in five college students reported in a survey that they knew someone who was addicted to pain medications, and nearly a third said they knew somebody who overdosed on painkillers or heroin. This may cause worry and anxiety above and beyond the typical financial and academic stress that college students face, the researchers added.
