A study of over 1 million urine drug tests from across the United States shows soaring rates of use of methamphetamines and fentanyl, often used together in potentially lethal ways.
The drug test results came primarily from clinics dealing with primary care, pain management or substance abuse disorders.
The results showed that between 2013 and 2019, urine samples testing positive for methamphetamine (“meth”) have skyrocketed sixfold, from about 1.4% of samples testing positive in 2013 to about 8.4% in 2019.
Similarly, the percentage of drug urine tests coming back positive for the highly potent—and sometimes fatal—opioid fentanyl have more than quadrupled since 2013, the study found. In 2013, just over 1% of the urine samples tested positive for fentanyl, but by 2019 that number was nearing 5%, said a team led by Dr. Eric Dawson, of Millennium Health in San Diego.
