Individuals often report using cannabis to sleep, experiencing sleep problems as a symptom of withdrawal, and relapsing due to sleep problems. This project endeavoured to integrate research on cannabis and sleep so that gaps in the literature can be identified and improvements in cannabis use interventions can be achieved.
Research to develop a better understanding of how cannabis use impacts on sleep and the extent to which cannabis use is associated with changes to sleep architecture is rarely conducted. Recognising the proportion of cannabis users who have sleeping problems or who use cannabis to assist their sleep may be clinically helpful when assisting individuals interested in abstaining from cannabis use.
- How many people report sleep disturbances before, during and after cannabis use
- The nature, severity and impact of these sleep disturbances
- The characteristics of people who report sleep disturbances before, during and after cannabis use.
All English language studies on human participants that include specific measure of cannabis and sleep were located and reviewed. In addition, each study was assigned a quality rating. The project aimed to produce a systematic review.

Two further systematic review articles for publication in Sleep Medicine Reviews will be submitted in 2013 and early 2014.
Recognising the effects of cannabis use on sleep is important for both the cannabis user and for health providers tasked with assisting behavioural change. That is, this knowledge may act as a motivational tool for those deciding whether or not to use cannabis. In addition, this knowledge may assist clinicians to reduce the risk of relapse to cannabis use among their clients by assessing and addressing sleep problems as necessary.
