Two studies found Black participants entered treatment with lower rates of stimulant (Sanchez, Chartier, et al, 2015;Sanchez et al, 2017) and methadone use (Wu, Blazer, Stitzer, Patkar, & Blaine, 2008), whereas others showed higher rates of current opioid use (Potter et al, 2013), other drug use (Cochran, Stitzer, Nunes, Hu, & Campbell, 2014), blunt use (Montgomery et al, 2019), and lifetime heroin use (E.
