Summary: Background: Sleep problems are more widespread in psychoactive substance users than in the general population. The precise nature of sleep disorders differs between stimulant users, especially between those who use crystal methamphetamine and opioid addicts. The aim of this study was to compare sleep disorders and quality in opioid and methamphetamine dependents. Methods: The participants in this study were divided into two groups: opioid (n = 120) and methamphetamine dependents (n = 115). All of the participants completed the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and a demographic characteristics form. Results: The findings revealed that sleep quality was low in both groups; both were defined as poor sleepers by the PSQI. A comparison between opioid and methamphetamine dependents revealed that the former group had a lower sleep quality (p = 0.004). Moreover, considering the ESS score of more than nine, a higher level of daytime drowsiness was reported by opioid dependents. Conclusions: The findings indicated that there was a relationship between the type of substance taken and the sleep quality and disorders experienced by an individual.
