Sleep disturbances from the use of cannabis

Abstract

This is a review of some clinical trials conducted on the impact on sleep structure, architecture and perception in cannabis users. For the literature search, consult database queries with special emphasis on systematic reviews, meta-analyzes, cohort studies, randomized controlled trials, and case-control studies. Keywords include terms that describe cannabis use combined with others that specify sleep or sleep abnormalities (for example: sleep, insomnia, polysomnography, total sleep time, sleep latency, slow wave sleep, motion sleep fast eyepiece and its latency). Relevant data was extracted in each of the articles consulted. The available literature is summarized on: subjective and objective measurements, clinical and paraclinical correlations, differences between acute and chronic consumption and abs-tinence, and other points of discussion. These are various molecular and anatomical corre-lations that explain changes in sleep from the point of view of the central nervous system. Finally, results frequently decrease sleep latency with acute use at low doses, plus shorter waking time after sleep onset, increased slow wave sleep and decreased rapid eye movement sleep, these effects do not persist with chronic use since later there is a worse quality of sleep; The setting also changes with abstinence where insomnia may occur, decreased total time for slow wave sleep and total sleep.
