Side effects experienced in the prior 24 hours were rated from 0—3 not at all, mild, moderate, severe. Vital signs were assessed at A cognitive performance battery was completed daily at Performance tasks took approximately 75 minutes to complete and all were completed prior to cannabis use to avoid any effects of acute cannabis intoxication. Study outcome measures were analyzed using a repeated measures regression with an AR 1 covariance structure.
Factors in the analyses included cannabis use condition ad-libitum use, abstinence , bedtime medication condition zolpidem, placebo , and time study day. Data analysis was completed using SAS statistical software Version 9. Participants had a reduction in total sleep time and sleep efficiency, and an increase in sleep latency during the zolpidem-abstinence period compared with cannabis use periods. Figure 1 illustrates mean scores for sleep continuity and REM measures on each day of abstinence.
Sleep continuity appears increasingly degrade over the three days of abstinence, while abstinence effects on REM sleep remain stable. The exception to this is that the effect of zolpidem on REM sleep appears to be delayed until the second day of abstinence. Participants reported more nocturnal awakenings and worse sleep quality during the placebo-abstinence phase compared with other study conditions.
All of these items increased in severity during abstinence relative to cannabis use periods, indicating cannabis withdrawal effects. No differences in withdrawal severity were observed between the placebo-abstinence and zolpidem-abstinence periods. No significant differences were observed for ratings of cannabis craving MCQ or medication side effects during the study. Main effects of cannabis use and time were observed for reaction time assessments on the N-back 1, 2, and 3-back and Tower of London, and for the number of attempted and correct DSST trials completed.
Post-hoc analyses for all of these measures showed that, despite the competency training conducted on Day 1, performance improved reduced reaction time, increased of DSST trials over time. This indicates that differences were due to practice effects, and the main effects of cannabis use observed simply reflect the fact that cannabis use periods always preceded cannabis abstinence periods. No significant differences were observed on other cognitive performance measure outcomes.
Analysis of blood pressure and heart rate assessments were limited to those obtained at the Clinical surveys and laboratory models of withdrawal indicate that sleep disturbance is common among frequent cannabis users and may directly contribute to either relapse to cannabis use or compensatory use of other drugs Budney et al.
However, most studies of cannabis withdrawal have relied on self-reported sleep assessments, which do not always accurately reflect actual sleep quality and do not provide information about sleep architecture Morgan et al. The present study provides objective evidence that abrupt cessation of daily cannabis use can indeed result in disrupted sleep continuity and altered sleep architecture, with latency to sleep onset and REM sleep most notably affected.
These findings confirm and extend previous studies indicating that abrupt marijuana cessation leads to sleep disruption, and provide the first data demonstrating that these effects can be attenuated with administration of hypnotic medication. The decreased sleep efficiency and increased sleep latency observed during cannabis withdrawal in the present study is consistent with prior studies Bolla et al.
Mean sleep efficiency scores during the cannabis withdrawal period exceeded the cutoff 0. Chronic decreases in sleep continuity have been associated with a variety of negative sequelae including fatigue, cognitive decline, decreased pain thresholds and spontaneous pain, increased anxiety and negative mood Stores, REM sleep is increasingly believed to play a role in affect regulation and memory related processes Stickgold and Walker, ; Wagner et al.
Thus, it is possible that secondary effects of reduced sleep continuity e. However, research is needed to determine whether or not these associations extend to changes in sleep induced by cannabis withdrawal. Some differences between the findings of the present study and those reported by Bolla and colleagues , warrant discussion. First, in contrast to the present study, Bolla et al.
For REM sleep, an increase during abstinence, consistent with what was observed in our study, would have resulted in more similarity to the control group no difference observed , and the gradual reduction in REM sleep observed over time may reflect a return to baseline. That said, we cannot eliminate the possibility that factors other than cannabis use impacted the data in the present study because a control group of non-cannabis users was not included. In this study, administration of extended-release zolpidem attenuated the effects of cannabis withdrawal on sleep.
Also, zolpidem administration significantly reversed abstinence induced changes in Stage 2 and REM sleep relative to the placebo-abstinence condition. Zolpidem did not reduce sleep latency as expected. This may be because it was administered when participants turned out the lights for the night, which likely did not allow enough time for the onset of clinical effects with the medication.
Thus, it is possible that zolpidem administered 20—30 minutes prior to bedtime would improve sleep continuity reduced sleep latency and increased sleep efficiency. Study participants self-reported significantly better sleep quality when they received active medication compared with placebo. This suggests that zolpidem may be useful for the treatment of sleep disturbance associated with cannabis withdrawal.
Additional research is warranted to determine whether the level of improvement in sleep quality obtained with zolpidem during cannabis withdrawal can translate to improved clinical outcomes for those trying to quit use of cannabis. With the exception of the speed with which responses were made on some tasks, cognitive performance assessed each morning remained stable throughout the study. This is consistent with prior research cf.
On the other hand, clinically significant sleep deficits have been associated with impaired cognitive abilities cf. Because sleep continuity and REM measures were significantly degraded during the cannabis withdrawal period it was somewhat surprising that a corresponding decrease in cognitive performance was not observed. It is possible that the duration of abstinence was not long enough for the development of cognitive impairment associated with cumulative sleep loss, or that the tasks used were not sensitive to the type e.
A recent literature review suggests that cognitive deficits among people with primary insomnia are subtle and inconsistently observed in controlled research studies not involving experimenter induced sleep deprivation Shekleton et al. Thus, the failure to find impairment on cognitive performance in the present study is not entirely unexpected or inconsistent with research on the cognitive consequences of poor sleep. There are limitations of the present study that warrant discussion.
The duration of abstinence studied was relatively short and there was a trend for sleep to become progressively worse over the three days of abstinence. Previous findings suggest that changes in sleep architecture persist for at least 2 weeks Bolla et al. A study of longer duration is needed to determine the peak severity and time course of abstinence-induced alterations of sleep architecture in daily cannabis users.
While extended-release zolpidem appears to have improved objective and subjective measures of sleep quality, this did not translate to a reduction in overall cannabis withdrawal severity or craving. That said, participant-rated withdrawal and craving scores were relatively low in this study, possibly because the duration of abstinence was short and the study was conducted in a residential setting devoid of the environmental cues associated with cannabis use that can exacerbate craving and withdrawal.
Replication of these effects using ambulatory sleep collection methods will be important to validate the present findings and the inpatient model. Also, participants in the present study were not seeking treatment. Additional research is needed to prospectively assess the correlation between sleep and relapse in a clinical population, and to determine whether an improvement in sleep quality can positively impact treatment success among those with cannabis use disorders.
In summary, this study provides objective evidence of sleep disturbance during cannabis withdrawal and suggests that pharmacological, and, possibly, behavioral interventions known to reduce sleep latency and normalize REM could be useful in the treatment of cannabis use disorders. Significant sleep disruption appears to be a common feature of withdrawal across drugs of abuse, and it has been suggested that sleep disturbance is a universal risk factor for relapse among those with drug use disorders Brower and Perron, Additional research is recommended to 1 examine the time course of cannabis withdrawal effects on sleep continuity and architecture, 2 replicate these effects in outpatient clinical samples, 3 prospectively establish the association between sleep and relapse during a quit attempt, 4 determine whether alternative medications or doses of zolpidem can further attenuate sleep disturbance, and 5 examine the commonality and treatment implications of abstinence-induced sleep disturbance in drug use disorders more broadly.

Abstract Background Sleep difficulty is a common symptom of cannabis withdrawal, but little research has objectively measured sleep or explored the effects of hypnotic medication on sleep during cannabis withdrawal.
Methods Twenty daily cannabis users completed a within-subject crossover study. Results During the placebo-abstinence period, participants had decreased sleep efficiency, total sleep time, percent time spent in Stage 1 and Stage 2 sleep, REM latency and subjective sleep quality, as well as increased sleep latency and time spent in REM sleep compared with when they were using cannabis. Conclusions These data extend prior research that indicates abrupt abstinence from cannabis can lead to clinically significant sleep disruption in daily users.
