Substance Use

The use of alcohol, tobacco and other drugs has long been associated with a range of public health problems, including cancer, chronic lung and liver disease, sexually transmitted and blood-borne infections and mental health. Our school's researchers are studying emerging trends associated with vaping, legalized recreational marijuana, and the U.S. opioid crisis, which now claims about 50,000 lives annually.

The availability of illicitly produced synthetic opioids has increased dramatically since 2013, worsening the public health crisis. In response to this crisis, research at the Yale School of Public Health includes epidemiological and geospatial analyses of opioid-involved fatalities in Connecticut and elsewhere in the United States that include assessing the potential public health benefits of expanded access to naloxone. Additionally, research is being conducted assessing the role of expedited referral to medication-based treatment through harm-reduction organizations and emergency departments in treating the underlying opioid-use disorder.
