Researchers use residues in wastewater to study illicit drug consumption

Rss Feed - Mon, 08/23/2021 - 18:01
At the start of the COVID-19 pandemic, stay-at-home orders and other restrictions drastically affected how people lived and worked, resulting in social isolation and economic instability. Now, researchers show that some people turned to a variety of drugs for relief. Using wastewater analysis, the team identified a spike in consumption of easily abused prescription opioids and anti-anxiety sedatives, while some illicit drug use plummeted, between March and June 2020.
