Background:
Fentanyl use in the Midwest is rising, and there is data to suggest that this is a particular area of concern among sexual and gender minorities assigned male at birth (SGM-AMABs). However, little is known about intentional and non-intentional use among this population. The goal of this study was to document rates of fentanyl use and associated indicators (e.g., mode of administration) among a cohort of SGM-AMABs.
Method:
Participants (N = 924) were drawn from the RADAR cohort study of SGM-AMABs recruited from the Chicago metropolitan area. All cohort members were designated male at birth and were required to be a sexual minority (i.e., individuals who are gay, bisexual, queer; have same-sex attraction/behavior; or endorse another non-heterosexual identity), a gender minority (i.e., individuals who are transgender, nonbinary, or another non-cisgender identity), or both. All participants completed a urine drug screen as well as self-report items regarding fentanyl use, mode of administration, opioid use, injection history, and overdose via REDCap survey instrument.
Results:
Of the 924 total participants, 0.3% (N = 3) self-reported fentanyl use, and 0.5% (N = 5) tested reactive via urine drug screen for fentanyl. Other substances of use were relatively common, and self-report fentanyl use was non-overlapping with urine drug screens for fentanyl.
Conclusions:
Although preliminary, these analyses suggest that fentanyl exposure is rare in this population. However, better screening methods to identify those who are using fentanyl by other modalities-including unintentional use-may be warranted.
