September 22, 2018 – A study from University of Pittsburgh Graduate School of Public Health shows drug overdose deaths have steadily increased over the past four decades, years before prescription opioids first flooded the streets. Dr. Donald Burke, the graduate school’s dean and the paper’s senior author, said drug overdose deaths “have been on an exponential growth curve” that began years before the rise in opioid prescriptions seen in the mid-1990s. “What’s surprising about this is that every point fits on the curve in a regular pattern,” Burke said. “The growth is approximately 8 percent every year, and it’s been going on for 40 years.” That wasn’t immediately obvious, Burke said. When researchers focused on one type of drug, such as cocaine or methamphetamine, they saw overdose deaths go up and down from year to year. However, when researchers plotted all overdose deaths, they saw a “remarkably smooth, long-term epidemic growth pattern” in the statistics.
