Cannabinoids and other components in cannabis can modulate many systems in the human brain and body. More than cannabinoids have been identified in the marijuana plant.
Although it doesn't make people feel high like THC , CBD is causing quite a buzz among scientists, health professionals, and medical marijuana patients who are using CBD -rich products to treat a wide range of conditions—including chronic pain, cancer, Crohn's, diabetes, rheumatoid arthritis, PTSD , cardiovascular disease, anxiety, antibiotic-resistant infections, multiple sclerosis, schizophrenia, and more.
Academic research centers around the world are currently studying the effects of CBD on these and other ailments. Extensive preclinical research and some clinical studies have shown that CBD may have strong anti-oxidant, anti-inflammatory, anticonvulsant, anti-depressant, anti-psychotic, anti-tumoral, and neuroprotective qualities. They appear to work best together.
CBD and THC both appear to stimulate neurogenesis, the creation of new brain cells, in adult mammals, which may prove helpful for stroke and Parkinson's patients. Products made from industrial hemp that contains little or no THC are currently being marketed widely. But recent scientific studies suggest that CBD -only products made from hemp of synthetic CBD may be less effective therapeutically than cannabis-based medicines because they lack critical secondary cannabinoids and other medicinal compounds that interact with CBD and THC to enhance their therapeutic benefits.
The best delivery system is one that provides an optimal dose for a desired duration with few unwanted aside effects. Flower for smoking or vaping is available in many medical marijuana dispensaries, but many medical patients prefer smoke-free products made from cannabis extract.
The time of onset and duration of effect vary depending on the method of administration. CBD -rich cannabis oil products can be taken sublingually, orally as edibles or gel caps , or applied topically. Concentrated cannabis oil extracts can also be heated and inhaled with a vape pen. Inhalation is good for treating acute symptoms that require immediate attention. The effects can be felt within a minute or two and typically last for a couple of hours. Interest in CBD is huge and growing, particularly among new medical marijuana patients who don't want to get high.
But many health professionals have little experience with cannabis therapeutics and have a hard time guiding people in this area. An effective dosage may range from as little as a few milligrams of CBD -enriched cannabis oil to a gram or more.
Take a few small doses over the course of the day rather than one big dose. Use the same dose and ratio for several days. Observe the effects and if necessary adjust the ratio or amount. Cannabis compounds have biphasic properties, which means that low and high doses of the same substance can produce opposite effects. Small doses of cannabis tend to stimulate; large doses sedate. Too much THC , while not lethal, can amplify anxiety and mood disorders.
CBD has no known adverse side effects, but an excessive amount of CBD could be less effective therapeutically than a moderate dose. Look for products with clear labels showing the quantity and ratio of CBD and THC per dose, a manufacturing date, and a batch number for quality control. Select products with quality ingredients: It has been proposed that cannabinoids may have some beneficial effects in the treatment of PD.
The majority of PD patients undergoing levodopa therapy develop disabling motor complications dyskinesias within 10 years of treatment. Recent studies in animal models and in the clinic suggest that CB1 receptor antagonists could prove useful in the treatment of both parkinsonian symptoms and levodopa-induced dyskinesia, whereas CB1 receptor agonists could have value in reducing levodopa-induced dyskinesia. This effect was significantly reduced by coinjection with the cannabinoid receptor agonist WIN 55, The simultaneous administration of the CB1 antagonist rimonabant with quinpirole and WIN 55, blocked the effect of WIN 55, on quinpirole-induced alleviation of akinesia.
This effect was also reversed by rimonabant. The injection of 0. In clinical trials, the cannabinoid receptor agonist nabilone significantly reduced levodopainduced dyskinesia in PD.
Advanced grades of HD showed an almost total loss of CB1 receptors and a further depletion of Dl receptors in the caudate nucleus, putamen, and globus pallidus internus, and an increase in GABA A receptor binding in the globus pallidus internus.
Indeed, arvanil, a hybrid endocannabinoid and vanilloid compound, behaves as an antihyperkinetic agent in a rat model of HD generated by bilateral intrastriatal application of 3-nitropropionic acid 3-NP. However, both capsaicin VR1 agonist and CP55, an CB1 agonist had antihyperkinetic activity Quinolinic acid QA is an excitotoxin which, when injected into the rat striatum, reproduces many features of HD by stimulating glutamate outflow.
Perfusion with WIN 55, significantly and dose-dependently prevented the increase in extracellular glutamate induced by QA. Thus, the stimulation of CB1 receptors might lead to neuroprotective effects against excitotoxic striatal toxicity.
Tourette syndrome TS is a complex inherited disorder of unknown etiology, characterized by multiple motor and vocal tics. Anecdotal reports have suggested that the use of cannabis might improve tics and behavioral problems in patients with TS. There was a significant improvement of motor tics, vocal tics and obsessive-compulsive behavior after treatment with THC.
Amyotrophic lateral sclerosis ALS is a fatal neurodegenerative disorder characterized by a selective loss of motor neurons in the spinal cord, brain stem, and motor cortex. Many effects of marijuana may be applicable to the management of ALS. These include analgesia, muscle relaxation, bronchodilation, saliva reduction, appetite stimulation, and sleep induction.
In addition, its strong antioxidative and neuroprotective effects may prolong neuronal cell survival. Furthermore, genetic ablation of the FAAH enzyme, which results in raised levels of the endocannabinoid anandamide, prevented the appearance of disease signs in these mice. Ablation of the CB1 receptor, in contrast, had no effect on disease onset in these mice, but significantly extended life span. Together these results show that cannabinoids have significant neuroprotective effects in this model of ALS, and suggest that these beneficial effects may be mediated by nonCB1 receptor mechanisms.
Administration at the onset of tremors delayed motor impairment in treated mice when compared with vehicle controls ; moreover, AM prolonged survival in these mice. Studies on cannabinoid anticonvulsant activity began in , when CBD, and four CBD derivatives, CBD-aldehyde-diacetate, 6-oxo-CBD-diacetate, 6-hydroxy-CBD-tri-acetate and 9-hydroxy-CBD-triacetate were shown to protect against maximal electroshock convulsions in mice, to potentiate pentobarbital sleeping-time and to reduce spontaneous motor activity.
Furthermore, it appears that CBD enhances the anticonvulsant effects of drugs in major seizures and reduces their effects in minor seizures. The induction of status epilepticus-like activity by CB1 receptor antagonists was reversible and could be overcome by maximal concentrations of CB1 agonists.
Cannabis use is common in patients with bipolar disorder, and anecdotal reports suggest that some patients use marijuana to alleviate symptoms of both mania and depression. The effect of cannabinoids on schizophrenia is controversial. Neuropsychological results in THC-intoxicated normal volunteers exhibit strong similarities with data acquired from patients suffering from productive schizophrenic psychoses, as regards disturbances in internal regulation of perceptual processes.
Data from experimental-psychological tests show that personality changes generated by schizophrenia progression are comparable to psychopathological phenomenon due to cannabis intoxication.
This argues against a distinct schizophrenia-like psychosis caused by cannabis. The group receiving the CB1 antagonist did not differ from the group receiving placebo on any outcome measure. CBD causes antipsychotic effects. Posttraumatic stress disorder PTSD is a term for severe psychological consequences of exposure to, or confrontation with, stressful, highly traumatic events. Cannabinoids are believed to help in such cases. AMtreated animals showed decreased shock-induced reinstatement of fear.
SRI blocked the effects of OL, suggesting that endogenous anandamide plays a facilitator role in extinction through a CB1 receptor mechanism of action. However, upon repeated stress or acute severe stress, CB1 receptor deficiency causes persistent behavioral inhibition. Repeated bell stress seemed to cause a cumulative fear in CB1 receptor knockout mice. CB1 receptor gene polymorphism is known to modify transcription of the gene.
In patients with Parkinson's disease, the presence of two long alleles, with more than 16 repeated AAT trinucleotides in the CNR1 gene, was associated with a reduced prevalence of depression. CBD, and some derivatives, were found to cause a selective anxiolytic effect in the elevated plus-maze, within a limited range of doses.
The effects of marijuana on human sleep patterns were noticed long ago. Asthma is a chronic disease of the respiratory system in which the airway occasionally constricts, becomes inflamed, and is lined with excessive amounts of mucus. In animal experiments, after methacholine-induced or exercise-induced bronchospasm, marijuana caused a prompt improvement of the bronchospasm and associated hyperinflation. The daily use of THC was not associated with clinical tolerance. Maximal bronchodilatation was achieved more rapidly with salbutamol, but at 1 hour both drugs were equally effective.
No cardiovascular or mood disturbance was detected, and plasma total cannabinoids at 15 minutes were not detected by radioimmunoassay. The mode of action of THC differed from that of sympathomimetic drugs. In another study, THC induced sympathetic stimulation and parasympathetic inhibition of cardiovascular control pathways. The peak heart rate rise after THC was attenuated by atropine and by propranolol, and nearly abolished by atropine-propranolol pretreatment.
With repetitive dosing supine bradycardia and decreased blood pressure with tolerance to orthostatic hypotension were observed. A number of studies suggest that there is a correlative, but not necessarily causal, relationship between glaucoma and systemic hypertension. Ocular hypertension OHT refers to any situation in which intraocular pressure is higher than normal, and is the most important risk factor for glaucoma.
In contrast, noladin ether decreased IOP immediately after topical administration, and no initial IOP increase was observed. CB2 mRNA was undetectable. Ocular toxicity was seen after THC treatment, consisting of conjunctival erythema and chemosis as well as corneal opacification. Although these changes also occurred with marijuana extract, their intensity was much reduced.
In contrast, no ocular toxicity was apparent during administration of plant cannabinoids other than THC. The results indicate that THC may have value as a hypotonizing ocular drug. The intensity and duration of the arterial and ocular pressure responses to THC were greater in hypertensives than in normotensive patients; the changes in ocular pressure paralleled the changes in blood pressure in glaucoma patients.
The antiproliferative action of cannabinoids on cancer cells was first noticed in the s. Since then cannabinoids were found to act on various cancer cell lines, through various mechanisms.
Moreover, cannabinoid challenge decreased the efficiency of glioma stem-like cells to initiate glioma formation in vivo.
Activation of these receptors decreased growth, proliferation, angiogenesis, and metastasis, and increased apoptosis, of melanomas in mice. These effects were prevented by blockade of the CB2 cannabinoid receptor or by pharmacologic inhibition of ceramide synthesis de novo. THC inhibited tumor-cell proliferation in vitro, decreased tumor-cell Ki67 immunostaining and prolonged the survival time of two of the patients.
Many drugs used today can cause addiction and are misused and abused, for example opiates, cocaine, benzodiazepines, barbiturates, cholinergic agonists, ketamine, , dopaminergic agonists, amphetamines, and others. Nevertheless they are still an important part of our pharmacopeia.
Marijuana was used for centuries as a medicinal plant, but during the last century, because of its abuse and addictive potential it was taken out of clinical practice. Now, we believe that its constituents and related compounds should be brought back to clinical use. The endocannabinoid system is a very complex one and regulates numerous processes, in parallel with other wellknown systems, such as the adrenergic, cholinergic, and dopaminergic systems.
