Test strips as an intervention
The seriousness of fentanyl contamination of illicit drugs, including cocaine and methamphetamine, was corroborated by two investigators at the School of Public Health and the Albert Einstein Medical School of Brown University, Providence, R.I. Brandon D.L. Marshall, PhD, associate professor of epidemiology in the School of Public Health, called fentanyl-contaminated cannabis “extremely rare,” but he said that it is being found in counterfeit prescription pills as well as in crystal methamphetamine and in both crack and powder cocaine.
He also advocated the use of fentanyl test strips.
“Test strips are an efficient, inexpensive, and effective way to determine whether fentanyl or related analogs are present in illicit drugs,” he said, noting that he is involved in a trial designed to determine whether fentanyl test strips can reduce the risk of fatal and nonfatal overdoses.
In a pilot study conducted in Baltimore, 69% of the 103 participants engaged in harm reduction behavior after using a fentanyl test strip and receiving a positive result (Addict Behav. 2020;110:106529). It is notable that 86% of the participants had a least one positive result when using the strips. More than half were surprised by the result.
One of the findings from this study was “that the lasting benefit of fentanyl test strip distribution is the opportunity to engage in discussions around safety and relationship building with historically underserved communities,” said the lead author, Ju Nyeong Park, PhD, assistant professor of medicine and epidemiology at Brown University. She moved to Brown after performing this work at Johns Hopkins University, Baltimore.
Dr. Park noted that “many patients in the community already know that they are using drugs containing fentanyl,” but for those who are concerned and wish to avoid contaminated drugs, fentanyl test strips “are a quick screening tool.” However, while the strips are helpful, she cautioned that they cannot be considered a definitive tool for detecting harm in illicit drugs.
“There may also be other chemicals present in tested drugs that confer risk,” she said.
