The U.S. is in the midst of an opioid epidemic, with approximately 12.5 million people who misused prescription opioids and over 33,000 deaths by opioid overdose in 2015.  The National Library of Medicine (NLM) recently released a portal on Opiate Addiction and Treatment with links to help health professionals learn more about opioid-related topics. Topics include understanding addiction, opioid overdose, and recovery.
