Effect of D-9-Tetrahydrocannabinol and Cannabidiol on Nocturnal Sleep and Early-Morning Behavior in Young Adults

The effects of cannabis extracts on nocturnal sleep, earlymorning performance, memory, and sleepiness were studied in 8 healthy volunteers (4 males, 4 females; 21 to 34 years). The study was double-blind and placebo-controlled with a 4-way crossover design. The 4 treatments were placebo, 15 mg D-9-tetrahydrocannabinol (THC), 5 mg THC combined with 5 mg cannabidiol (CBD), and 15 mg THC combined with 15 mg CBD. These were formulated in 50:50 ethanol to propylene glycol and administered using an oromucosal spray during a 30-minute period from 10 PM. The electroencephalogram was recorded during the sleep period (11 PM to 7 AM). Performance, sleep latency, and...

Effect of illicit recreational drugs upon sleep: Cocaine, ecstasy and marijuana

The illicit recreational drugs cocaine, ecstasy and marijuana have pronounced effects upon sleep. Administration of cocaine increases wakefulness and suppresses REM sleep. Acute cocaine withdrawal is often associated with sleep disturbances and unpleasant dreams. Studies have revealed that polysomnographically assessed sleep parameters deteriorate even further during sustained abstinence, although patients report that sleep quality remains unchanged or improves. This deterioration of objective sleep measures is associated with a worsening in sleep-related cognitive performance. Like cocaine, 3,4-methylenedioxymethamphetamine (MDMA; "ecstasy") is a substance with arousing properties. Heavy MDMA consumption is often associated with persistent sleep disturbances. Polysomnography (PSG) studies have demonstrated altered sleep architecture in abstinent...

(−)δ9 THC as an hypnotic

(−)δ 9 THC was found to significantly decrease the time it takes to fall asleep in physically healthy insomniacs. Once asleep, interruptions of sleep were not significantly altered over the whole night. The (−)δ 9 THC tended to be associated with some decrease in awakenings in the first half of the night. The primary side effect experienced by the subjects at all dose levels in the Pre­Sleep phase was temporal disorganization and mood alterations. There was an increase in intensity of side effects and number of subjects affected with increasing dosage. The most significant side effect, however, was a “hangover” phenomenon, or continued “high”...

Functional Role for Cannabinoids in Respiratory Stability During Sleep

Study Objectives: Serotonin, acting in the peripheral nervous system, can exacerbate sleep-related apnea, and systemically administered serotonin antagonists reduce sleep-disordered respiration in rats and bulldogs. Because cannabinoid receptor agonists are known to inhibit the excitatory effects of serotonin on nodose ganglion cells, we examined the effects of endogenous (oleamide) and exogenous (∆9-tetrahydrocannabinol; ∆9THC) cannabimimetic agents on sleep-related apnea. Design: Sleep architecture, respiratory pattern, and apnea expression in rats were assessed by polysomnography. A repeated measures, withinsubjects, fully nested crossover design was used in which each animal was recorded on exactly 12 occasions. Participants: Eleven adult male Sprague-Dawley rats were instrumented for chronic polysomnography. Interventions:...

Intrahippocampal administration of anandamide increases REM sleep

A nascent literature has postulated endocannabinoids (eCBs) as strong sleep-inducing lipids, particularly rapid-eye-movement sleep (REMs), nevertheless the exact mechanisms behind this effect remain to be determined. Anandamide and 2-arachidonyl glycerol, two of the most important eCBS, are synthesized in the hippocampus. This structure also expresses a high concentration of cannabinoid receptor 1 (CB1). Recent extensive literature supports eCBs as important regulators of hippocampal activity. It has also been shown that these molecules vary their expression on the hippocampus depending on the light–dark cycle. In this context we decided to analyze the effect of intrahippocampal administration of the eCB anandamide (ANA) on the sleep–waking cycle...

Intranodose ganglion injections of dronabinol attenuate serotonin-induced apnea in Sprague-Dawley rat

Obstructive sleep apnea represents a significant public health concern. Afferent vagal activation is implicated in increased apnea susceptibility by reducing upper airway muscle tone via activation of serotonin receptors in the nodose ganglia. Previous investigations demonstrated that systemically administered cannabinoids can be used therapeutically to decrease the apnea/ hypopnea index in rats and in humans. However, cannabinoids have effects on both the central and peripheral nervous systems, and the exact mechanism of decreased apnea/hypopnea index with cannabinoids is unknown. Here, we hypothesized that intranodose ganglion injections of a cannabinoid will attenuate 5-HT-induced reflex apnea and increase upper airway muscle tone. We show that dronabinol...

Potential Effects of Cannabidiol as a Wake-Promoting Agent

Over the last decades, the scientific interest in chemistry and pharmacology of cannabinoids has increased. Most attention has focused on Δ9 -tetrahydrocannabinol (Δ9 -THC) as it is the psychoactive constituent of Cannabis sativa (C. sativa). However, in previous years, the focus of interest in the second plant constituent with non-psychotropic properties, cannabidiol (CBD) has been enhanced. Recently, several groups have investigated the pharmacological properties of CBD with significant findings; furthermore, this compound has raised promising pharmacological properties as a wake-inducing drug. In the current review, we will provide experimental evidence regarding the potential role of CBD as a wake-inducing drug.

Proof of concept trial of dronabinol in obstructive sleep apnea

Study Objective: Animal data suggest that ∆9 -TetraHydroCannabinol (∆9THC) stabilizes autonomic output during sleep, reduces spontaneous sleep-disordered breathing, and blocks serotonin-induced exacerbation of sleep apnea. On this basis, we examined the safety, tolerability, and efficacy of dronabinol (∆9THC), an exogenous Cannabinoid type 1 and type 2 (CB1 and CB2) receptor agonist in patients with Obstructive Sleep Apnea (OSA). Design and Setting: Proof of concept; single-center dose-escalation study of dronabinol. Participants: Seventeen adults with a baseline Apnea Hypopnea Index (AHI) ≥15/h. Baseline polysomnography (PSG) was performed after a 7-day washout of Continuous Positive Airway Pressure treatment. Intervention: Dronabinol was administered after baseline PSG, starting at...

The effects of cannabinoid administration on sleep: a systematic review of human studies

This paper reviews the literature regarding the effects of cannabinoid administration on sleep in humans. A literature search using a set of cannabinoid and sleep-related terms was conducted across eight electronic databases. Human studies that involved the administration of cannabinoids and at least one quantitative sleep-related measure were included. Review papers, opinion pieces, letters or editorials, case studies (final N < 7), published abstracts, posters, and non-English papers were excluded. Thirty-nine publications were included in the review. Findings were mixed and showed various effects of cannabinoid administration on several aspects of sleep. Methodological issues in the majority of studies to date, however, preclude any...

The Emerging Role of the Endocannabinoid System in the Sleep-Wake Cycle Modulation

The endocannabinoid system comprises amides, esters and ethers of long chain polyunsaturated fatty acids. Narachidonoylethanolamide (anandamide; ANA) and 2-arachidonoylglycerol (2-AG) are endogenous cannabinoids (endocannabinoids) ligands for the cannabinoid family of G-protein-coupled receptors named CB1 and CB2. Endocannabinoids are released upon demand from lipid precursors in a receptor-dependent manner and behave as retrograde signaling messengers, as well as modulators of postsynaptic transmission, interacting with other neurotransmitters systems. The two principal enzymes that are responsible for the metabolism of ANA and 2-AG are fatty acid amide hydrolase and monoacylglycerol lipase, respectively. Pharmacological experiments have shown that the administration of endocannabinoids induce cannabimimetic effects, including sleep promotion....
