“A YOUNG mother using cannabis to help her sleep has been given the benefit of the probation act at Wexford District Court.

Shelly Donnelly, Moortown Great, Ballmitty, had pleaded guilty to the possession of cannabis at her home on June 11, 2010.

Judge Donnchadh O Buachalla heard that the property at Moortown Great was searched and a small quantity of cannabis herb was found. It was for Donnelly’s own use.

Eva Lalor, for Donnelly, said her client is 24years-old and has a fiveyear-old daughter with her long-term partner.

Ms Lalor said Donnelly was suffering from insomnia following a family bereavement and was using cannabis to help her sleep. Donnelly, who has no previous convictions, is now on medication to help her sleep.

Judge O Buachalla gave her the benefit of the probation act, saying that he hopes she has learnt her lesson from the experience.”

Mark Jackson has escaped without having a conviction recorded for his latest drug offences.

HOSPITALITY manager Mark Jackson has been fined for possessing marijuana, which he smoked after night work to help him get some sleep.

Jackson has a history of drug use dating back to 2000, when the Supreme Court gave him a suspended jail sentence for supplying drugs.

However, his last drug-related offence was in 2005.

Jackson, a 48-year-old who supports four dependents, pleaded guilty in Mackay Magistrate’s Court yesterday to the unlawful possession of a small amount of marijuana and a pipe last October 20.

Police executed a search warrant at his Andergrove home at 12.45am and Jackson was the sole occupant, prosecutor Constable Janelle Young said.

Asked if he had anything to declare, he said he had a bong beside his bed.

A homemade pipe and a small amount of marijuana were found.

He told police he had smoked some marijuana that morning, after night work, because it helped him to sleep.

The items were seized and he was issued with a property receipt.

Duty lawyer John Aberdeen said Jackson “holds a managerial position in hospitality” and did mostly night work.

His previous convictions in 2000 and 2005 were acknowledged but the new offences involved only a small amount of drugs for personal use, Mr Aberdeen said.

Mr Aberdeen asked for no conviction to be recorded because of the length of time that had elapsed since the last offence.

Magistrate Damien Dwyer imposed a fine of $600 and ordered that no conviction be recorded.”

Smoking Cannabis Reduces Pain, Helps Sleep And Improves Mood For Those With Chronic Symptoms

“For patients with chronic (long-term) neuropathic pain, smoking cannabis was found to reduce symptoms of pain, improve mood and help sleep, a report published in CMAJ (Canadian Medical Journal Association) revealed. When damage or dysfunction of the nervous system results in chronic neuropathic pain, patients have few treatment options, such as antidepressants, local anesthetics, anticonvulsants or opioids. However, these medications often have undesirable side effects and do not work for everybody.

The authors inform that oral cannabinoids have been effective in reducing the symptoms of some types of pain. However, they many have different effects and risks compared to smoked cannabis.

Investigators from McGill University Health Centre (MUHC) and McGill University carried out a randomized, controlled trial to determine the analgesic effect of smoked cannabis in 21 patients, aged 18 years or more, all of them with chronic neuropathic pain. THC levels (drug potencies) were divided into 2.5%, 6% and 9.4%. Some participants also received a placebo (0%).

The researchers inform that there was a correlation between increased THC content and better sleep quality. Symptoms of depression and/or anxiety were also reduced at 9.5% THC level.”

The nonpsychoactive Cannabis constituent cannabidiol is a wake-inducing agent.

“Cannabidiol (CBD) is a constituent of Cannabis sativa that induces nonpsychotropic effects, and some of its biological actions in sleep have been described by the authors’ group.

 Here, the authors report that when administered 10 or 20 microg/1 microl during the lights-on period directly into either lateral hypothalamus (LH) or dorsal raphe nuclei (DRN), which are wake-inducing brain areas, CBD enhanced wakefulness and decreased slow wave sleep and REM sleep. Furthermore, CBD increased alpha and theta power spectra but diminished delta power spectra. Additionally, CBD increased c-Fos expression in LH or DRN.

These findings suggest that this cannabinoid is a wake-inducing compound that presumably activates neurons in LH and DRN.”

Cannabidiol, a constituent of Cannabis sativa, modulates sleep in rats.

“Delta(9)-tetrahydrocannabinol (Delta(9)-THC) and cannabidiol (CBD) are two major constituents of Cannabis sativa. Delta(9)-THC modulates sleep, but no clear evidence on the role of CBD is available.

In order to determine the effects of CBD on sleep, it was administered intracerebroventricular (icv) in a dose of 10 microg/5 microl at the beginning of either the lights-on or the lights-off period. We found that CBD administered during the lights-on period increased wakefulness (W) and decreased rapid eye movement sleep (REMS). No changes on sleep were observed during the dark phase. Icv injections of CBD (10 microg/5microl) induced an enhancement of c-Fos expression in waking-related brain areas such as hypothalamus and dorsal raphe nucleus (DRD). Microdialysis in unanesthetized rats was carried out to characterize the effects of icv administration of CBD (10 microg/5 microl) on extracellular levels of dopamine (DA) within the nucleus accumbens. CBD induced an increase in DA release. Finally, in order to test if the waking properties of CBD could be blocked by the sleep-inducing endocannabinoid anandamide (ANA), animals received ANA (10 microg/2.5 microl, icv) followed 15 min later by CBD (10 microg/2.5 microl). Results showed that the waking properties of CBD were not blocked by ANA.

 In conclusion, we found that CBD modulates waking via activation of neurons in the hypothalamus and DRD. Both regions are apparently involved in the generation of alertness. Also, CBD increases DA levels as measured by microdialysis and HPLC procedures.

Since CBD induces alertness, it might be of therapeutic value in sleep disorders such as excessive somnolence.”

[The modulatory role of endocannabinoids in sleep].

“The endogenous cannabinoid, or endocannabinoid, system is present in the central nervous system (CNS) of rodents and humans. This system includes receptors, endogenous ligands and enzymes. The presence of cannabinoid receptors, called CB1, in the CNS has been reported in the cerebral cortex, the hippocampus, the cerebellum and the brain stem. This neuroanatomical location suggests that this receptor could modify several physiological functions, such as the consolidation of memory, motor control and the generation of sleep.

 

Recent reports have described the presence of lipids in the CNS that bind to the CB1 receptor. Administration of said molecules induces cannabimimetic effects, and hence it has been suggested that these lipids are endogenous cannabinoids or endocannabinoids. Anandamide, 2-arachidonylglycerol, virodhamine, noladin ether and N-arachidonyldopamine are molecules that belong to the endocannabinoid family. Anandamide has received more attention from researchers because it was the first endocannabinoid to be reported. Pharmacological experiments have shown that this endocannabinoid induces several different intracellular and behavioural changes.

CONCLUSIONS:

In this study, we review the most important pharmacological aspects of exogenous cannabinoids and the neurobiological role played by the endocannabinoid system, including endogenous and exogenous ligands and receptors. We also examine their pharmacological effects on different behaviours, with particular attention given to the modulation of sleep.”

The role of the CB1 receptor in the regulation of sleep.

“During the 1990s, transmembranal proteins in the central nervous system (CNS) that recognize the principal compound of marijuana, the delta-9-tetrahydrocannabinol (Delta9-THC) were described. The receptors were classified as central or peripheral, CB1 and CB2, respectively. To this date, it has been documented the presence in the CNS of specific lipids that bind naturally to the CB1/CB2 receptors.

The family of endogenous cannabinoids or endocannabinoids comprises oleamide, arachidonoylethanolamine, 2-arachidonylglycerol, virodhamine, noladin ether and N-arachidonyldopamine. Pharmacological experiments have shown that those compounds induce cannabimimetic effects. Endocannabinoids are fatty acid derivates that have a variety of biological actions, most notably via activation of the cannabinoid receptors. The endocannabinoids have an active role modulating diverse neurobiological functions, such as learning and memory, feeding, pain perception and sleep generation.

Experimental evidence shows that the administration of Delta9-THC promotes sleep.

 The activation of the CB1 receptor leads to an induction of sleep, this effect is blocked via the selective antagonist.

Since the system of the endogenous cannabinoids is present in several species, including humans, this leads to the speculation of the neurobiological role of the endocannabinoid system on diverse functions such as sleep modulation.

This review discusses the evidence of the system of the endocannabinoids as well as their physiological role in diverse behaviours, including the modulation of sleep.”

“Cannabidiol (CBD) is one of the main components of Cannabis sativa and has a wide spectrum of action, including effects in the sleep-wake cycle. Objective: The objective of this paper is to assess the effects on sleep of acute systemic administration of CBD.

 Method: Adult male Wistar rats were randomly distributed into four groups that received intraperitoneal injections of CBD 2.5 mg/kg, CBD 10 mg/kg, CBD 40 mg/kg or vehicle (n=seven animals/group). Sleep recordings were made during light and dark periods for four days: two days of baseline recording, one day of drug administration (test), and one day after drug (post-test). Results: During the light period of the test day, the total percentage of sleep significantly increased in the groups treated with 10 and 40 mg/kg of CBD compared to placebo. REM sleep latency increased in the group injected with CBD 40 mg/kg and was significantly decreased with the dose of 10 mg/kg on the post-test day. There was an increase in the time of SWS in the group treated with CBD 40 mg/kg, although this result did not reach statistical significance.

 Conclusion: The systemic acute administration of CBD appears to increase total sleep time, in addition to increasing sleep latency in the light period of the day of administration.”

“The oral administration of synthetic THC reduces symptoms of sleep apnea, according to clinical trial data published online in the scientific journal Frontiers in Psychiatry. Sleep apnea is a medical disorder characterized by frequent interruptions in breathing of up to ten seconds or more during sleep. The condition is associated with numerous physiological disorders, including fatigue, headaches, high blood pressure, irregular heartbeat, heart attack and stroke.

Investigators at the University of Illinois at Chicago, Department of Medicine assessed the safety, tolerability, and efficacy of dronabinol (oral THC in sesame seed oil) in 17 subjects with Obstructive Sleep Apnea.

Oral THC administration was associated with a significant change in Apnea Hypopnea Index over a 21-day period. Authors further determined dronabinol treatment to be safe and well tolerated.

They concluded, “These findings should be confirmed in a larger study in order to identify sub-populations with OSA that may benefit from cannabimimetic pharmacologic therapy.”

Dronabinol, marketed under the trade name Marinol, is FDA-approved to treat nausea and vomiting caused by chemotherapy.”
