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 percent of samples testing positive in 2013 to about 8.4 percent in 2019.
