a) Lifetime overdose on any drug and b) past-year overdose on heroin or other opioids among individuals reporting illicitly manufactured fentanyl use, heroin use, or prescription opioid misuse as their primary lifetime substance use problem, Note: Among the original sample, 0.15% of assessments for illicitly manufactured fentanyl, 0.14% of assessments for heroin, 0.28% of assessments for misuse of prescription opioids did not answer the question about past-year overdose on heroin or other opioids. Eighty-two percent (82.2%) of assessments for illicit fentanyl, 80.6% of assessments for heroin, and 42.3% of assessments for misuse of prescription opioids were not presented to individuals about the past year overdose question dur to the skip logic (i.e., variable existed but was not presented due to logic skip). Therefore, we excluded those missing observations.
