Fentanyl in rural Michigan
Michigan Overdose Data to Action
The overdose epidemic remains one of the most pressing public health issues, with more than a half million deaths in the US over the past decade and nearly 100,000 deaths in 2020 alone.1 Most of these deaths are opioid involved, though the type of opioid has varied across multiple waves, each one resulting in more deaths than the last. Increases in overdose deaths initially began with the increased availability of prescription opioids.2,3 As the availability of prescription opioids decreased, a second wave of overdose was initiated as opioid users transitioned to heroin2,4-5 and then beginning in 2013, the third wave of the overdose epidemic was driven by fentanyl, a synthetic opioid 50 to 100 times more potent than morphine.6,7The most recent trends in national overdose data suggest sharp increases in deaths associated with synthetic stimulants, cocaine and methamphetamines,8 which some have labeled as the fourth wave of the epidemic.9
This return to methamphetamines has been highlighted in Michigan, particularly among populations in criminal-legal systems, with research showing stimulants more likely to be detected through urine testing than opioids.10 However, drugs being seized or detected by law enforcement are not always the same substances detected in overdose deaths. To examine this the CBHJ partnered with the Mid Michigan Medical Examiner Group to examine postmortem toxicology results from overdose deaths that occurred between January 1, 2018 and December 31, 2020 in 11 rural counties (Alpena, Clare, Crawford, Lake, Mecosta, Montcalm, Montmorency, Newaygo, Oceana, Otsego, and Wexford).
Among 107 deaths that occurred over the three-year period we examined the detection of fentanyl, heroin, prescription opioids, cocaine, methamphetamine, and benzodiazepines. As illustrated in Figure 1, fentanyl was overwhelmingly the most common substance detected. There was a 94% increase during the three-year period, with fentanyl present in 70% of all the deaths in these counties in 2020. Prescription opioids detection also increased from 2019 to 2020, from 24% to 28%. Cocaine presence decreased from 28% in 2018 to only 8% in 2020 while methamphetamine detection increased from 18% in 2018 to about 30% in 2019 and 2020. Benzodiazepines decreased from 36% in 2018 to 20% in 2020.

While historical trends suggest opioids and stimulants alternate in periods of use, current patterns suggest polydrug co-use among these substances along with instances of dealers cutting heroin and other illicit substances with fentanyl.11 Therefore, consistent with national data we found that stimulants are rarely detected outside of polydrug combinations that contain fentanyl. In fact, of the deaths we examined where cocaine was detected, 69% also contained fentanyl as did 77% of deaths with methamphetamine detected.
"Stimulants are rarely detected outside of polydrug combinations that contain fentanyl. In fact, of the deaths we examined where cocaine was detected, 69% also contained fentanyl as did 77% of deaths with methamphetamine detected."
Figure 2 illustrates the polydrug detections among these substances across each year that data were collected. The thickness of each line represents the frequency of occurrences between connected drugs for a given year. The node size represents the frequency of each specific drug. Thus, the thicker line, the more frequent the occurrence of certain polydrug combinations. Each line can be compared across years to examine changing frequencies of unique polydrug combinations. As illustrated here, in rural Michigan fentanyl has been the dominant substance in overdose deaths since 2019, first in combination with methamphetamine and more recently alone, as fentanyl was detected without any of these substances in 28% of the 2020 cases.

The lack of a "safe supply" is driving overdose increases, as illicit opioid users have shifted from prescription medications, to heroin, to heroin (and potentially other substances) cut with fentanyl. The federal government approved the purchase of "fentanyl testing strips" which allows someone to place a small amount of the drug sample in a small container, add water, and swirl the testing strip in the sample for about 15 seconds. After 2 minutes, a red line may appear on the strip which indicates the presence of fentanyl. You can watch a brief video and download printable instructions; contact the CBHJ for information on ordering the test strips.
Drug checking can provide people who use drugs the ability to identify the presence of fentanyl in unregulated drugs. Testing strips can be applied broadly to drugs that are injectable, powder or pills. Being aware if fentanyl is present is a powerful overdose prevention tool and allows people to implement appropriate harm reduction strategies to reduce the risk of an overdose.12-14
