Drug overdoses in young people on the rise

Death rates from drug poisoning in American adolescents and young adults rose significantly over the last decade, mainly fueled by opioid-related deaths. The estimated costs of these deaths were $27.1 million in medical costs, $8.5 billion in work loss costs, and $26.5 billion for quality-of-life loss in 2015.
