The opioid epidemic is raging across the United States as the result of the escalation of the therapeutic use of opioids and other psychotherapeutics as well as their abuse and nonmedical use over the past 30 years. Opioid analgesics are now responsible for more deaths than the deaths from both suicide and motor vehicle crashes. The opioid epidemic in the United States is not only a public health emergency but also a social epidemiological emergency as it evolves with disparate mortality rates between races/ethnicities. This study investigates the spatial and temporal patterns of the poisoning mortality in the United States from 1980 to 2016. In addition, time trend and spatial pattern of the mortality are studied as they are stratified and confounded by race/ethnicity, age, period, and cohort effects. The study offers the understandings of how the epidemic evolves over time in the United States, and how different time effects and demographic factors contribute to the epidemic.
