Notes.
Weighted results from the 2018 National Survey on Drug Use and Health (NSDUH) for adults who self-reported past-year use of cocaine.
Data for drug overdose deaths involving cocaine among adults in the US in 2018. No 95% CIs were included as mortality data represent a census, rather than a sample.
Including opium, heroin, prescription opioids, methadone, and synthetic opioids.
Hydrocodone, oxycodone, oxymorphone, hydromorphone, morphine, or codeine products; excludes methadone.
Excluding methadone; n.a. for NSDUH, as NSDUH does not report on all drugs in the synthetic opioid category.
Methamphetamine, amphetamine or methylphenidate products, or 3,4-Methylenedioxymethamphetamine (MDMA); deaths involving psychostimulants with abuse potential most frequently involve methamphetamine (Ossiander, 2014). Abbreviations. CI, confidence interval; n.a., Not applicable.
