Description:

Currently the US in the midst of an opioid epidemic that claims of the lives of 115 per day who die from overdose.  One critical component of this public health crisis is illicit access to prescription opioids and other opioid-derived drugs (including heroin and synthetic opioids such as fentanyl).  In fact, there are may ways to illicitly source drugs, including via the Internet, where illegal online pharmacies and drug dealers market and sell their products directly to consumers.  One part of the Internet that is subject to rising scrutiny is social media, where popular platforms such as Twitter, Facebook, and Instagram, have been identified as conduits for illegal opioid access.  In this talk, I will discuss research conducted by a multidisciplinary team of public health and computer science experts on using machine learning to detect, classify and report illicit online sales of opioids.  The discussion will include the data management, analysis, classification, and visualization approaches used by the team, efforts to translate results to policy action with various stakeholders, and current commercialization activities through grant mechanisms. I will also discuss broader application of the methods to other use cases.
