Activation of 5-HT 1A Rs appears to mediate anxiolytic and panicolytic effects, in addition to reducing conditioned fear expression, although CB 1 R activation may play a limited role. While CBD predominantly has acute anxiolytic effects, some species discrepancies are apparent.
In addition, effects may be contingent on prior stress and vary according to brain region. Further receptor-specific studies may elucidate the receptor specific basis of this distinct dose response profile. Further studies are also required to establish the efficacy of CBD when administered in chronic dosing, as relatively few relevant studies exist, with mixed results, including both anxiolytic and anxiogenic outcomes. In particular, results show potential for the treatment of multiple PTSD symptom domains, including reducing arousal and avoidance, preventing the long-term adverse effects of stress, as well as enhancing the extinction and blocking the reconsolidation of persistent fear memories.
The anxiolytic effects of CBD in humans were first demonstrated in the context of reversing the anxiogenic effects of THC. CBD reduced THC-induced anxiety when administered simultaneously with this agent, but had no effect on baseline anxiety when administered alone [ 99 , ].
Further studies using higher doses supported a lack of anxiolytic effects at baseline [ , ]. By contrast, CBD potently reduces experimentally induced anxiety or fear. CBD reduced anxiety associated with a simulated public speaking test in healthy subjects, and in subjects with SAD, showing a comparable efficacy to ipsapirone a 5-HT 1A R agonist or diazepam [ 98 , ].
CBD also reduced the presumed anticipatory anxiety associated with undergoing a single-photon emission computed tomography SPECT imaging procedure, in both healthy and SAD subjects [ , ].
Finally, CBD enhanced extinction of fear memories in healthy volunteers: These rCBF changes were not correlated with anxiolytic effects [ ]. In a series of placebo-controlled studies involving 15 healthy volunteers, Fusar-Poli et al.
Response activation is diminished in PTSD and other anxiety disorders, and increased activation predicts response to treatment [ ]. CBD produced no changes in predicted areas relative to placebo but reduced activation in the left insula, superior temporal gyrus, and transverse temporal gyrus. The fearful faces task activates the amygdala, and other medial temporal areas involved in emotion processing, and heightened amygdala response activation has been reported in anxiety disorders, including GAD and PTSD [ , ].
CBD attenuated blood-oxygen-level dependent activation in the left amygdala, and the anterior and posterior cingulate cortex in response to intensely fearful faces, and also reduced amplitude in skin conductance fluctuation, which was highly correlated with amygdala activation [ ].
Dynamic causal modeling analysis in this data set further showed CBD reduced forward functional connectivity between the amygdala and anterior cingulate cortex [ ]. Epidemiological studies of various neuropsychiatric disorders indicate that a higher CBD content in chronically consumed cannabis may protect against adverse effects of THC, including psychotic symptoms, drug cravings, memory loss, and hippocampal gray matter loss [ — ] reviewed in [ ].
As THC acutely induces anxiety, this pattern may also be evident for chronic anxiety symptoms. Two studies were identified, including an uncontrolled retrospective study in civilian patients with PTSD patients [ ], and a case study in a patient with severe sexual abuse-related PTSD [ ], which showed that chronic cannabis use significantly reduces PTSD symptoms; however, these studies did not include data on the THC: Thus, overall, no outcome data are currently available regarding the chronic effects of CBD in the treatment of anxiety symptoms, nor do any data exist regarding the potential protective effects of CBD on anxiety potentially induced by chronic THC use.
Evidence from human studies strongly supports the potential for CBD as a treatment for anxiety disorders: Limited results in healthy subjects also support the efficacy of CBD in acutely enhancing fear extinction, suggesting potential for the treatment of PTSD, or for enhancing cognitive behavioral therapy.
Further studies are also required to establish whether chronic, in addition to acute CBD dosing is anxiolytic in human. Human experimental findings support preclinical findings, and also suggest a lack of anxiogenic effects, minimal sedative effects, and an excellent safety profile. Overall, this review emphasizes the potential value and need for further study of CBD in the treatment of anxiety disorders.

Despite the government ruling, CBD is widely available over the counter in dispensaries in states where marijuana is legal. The piece, reported by Dr Sanjay Gupta, featured a little girl in Colorado named Charlotte, who had a rare life-threatening form of epilepsy called Dravet syndrome.
At age five, Charlotte suffered grand mal seizures a week, and was constantly on the brink of a medical emergency. It was controversial to pursue medical marijuana for such a young patient, but when they gave Charlotte oil extracted from high-CBD cannabis, her seizures stopped almost completely.
Instead of moving, other families obtained CBD oil through the illegal distribution networks. If Epidiolex wins approval it would be the first time the agency approves a drug derived from the marijuana plant. Epidiolex was developed by the London-based GW Pharmaceuticals , which grows cannabis on tightly controlled farms in the UK.
While parents treating their children with CBD had to proceed based on trial and error, like a folk medicine, they also had to wonder whether dispensary purchased CBD was professionally manufactured and contained what the package said it did. Commonly used pharmaceuticals for depression often target serotonin, a chemical messenger that is believed to act as a mood stabilizer. The neural network of the endocannabinoid system works similarly to the way that serotonin, dopamine, and other systems do, and, according to some research, cannabinoids have an effect on serotonin levels.
Whereas a low dose of THC increases serotonin, high doses cause a decrease that could worsen the condition. CBD products with a ratio of Specifically, products made with Valentine X or Electra 4 are more energizing, helping relieve depression.
When low energy is an issue, sativa or other stimulating strains can be helpful for improving energy and focus when THC can be tolerated. Varieties that are high in the terpene limonene are recommended for mood elevation. Always start with the micro dose to test sensitivity and go up as needed within the dosing range before going to the next, until symptoms subside. The micro to standard dose is usually recommended to treat depression.
Vaporized or smoked cannabis is recommended for relief of immediate symptoms, or a boost in dosage, and it can also be useful for sleep issues. The Cannabis Health Index CHI is an evidence-based scoring system for cannabis in general, not just CBD effects and its effectiveness on various health issues based on currently available research data.
Using this rubric and based on twenty-one studies, cannabis rated in the possible-to-probable range of efficacy for treatment of depression. Research in called for clinical trials to look into the effectiveness of cannabinoids for bipolar disorder manic depression.
It also works on the GABA-glutamate system and the hypothalamic-pituitary-adrenal axis. Its main role is restoring balance through inhibition when levels are too high and enhancement when they are too low. This is the most likely reason phytocannabinoids in general and CBD specifically are able to regulate depression and anxiety. The scientific inquiry into cannabis over the past several decades has confirmed that it is an effective and safe analgesic for many kinds of pain.
Of all the reasons that people use CBD today, pain is the most common. The same can be said of cannabis in general. In the United States, over seventy million people suffer from chronic pain, which is defined as experiencing over one hundred days per year of pain. Physicians differentiate between neuropathic usually chronic and nociceptive pains usually time-limited , and cannabis works on most neuropathic and many nociceptive types of pain.
A number of studies have demonstrated that the endocannabinoid system is both centrally and peripherally involved in the processing of pain signals. Cannabinoids can be used along with opioid medications, and a number of studies have demonstrated that they can reduce the amount of opioids needed, lessen the buildup of tolerance, and reduce the severity of withdrawal.
It is suggested that patients work with a health care practitioner experienced in recommending CBD oil or medicinal cannabis so that dosage and delivery methods can be developed and fine-tuned on an individual basis. Oral CBD products with a ratio of Most discussions of treating pain with CBD suggest that finding the right dosage is critical. Always start with the micro dose to test sensitivity and go up as needed within the dosing range by body weight until symptoms subside. If CBD-dominant products alone are not enough to treat a particular case, products with a higher ratio of THC are sometimes recommended to better manage pain.
For day use, more stimulating, sativa varieties with higher concentrations of myrcene could be added to the formula. In general, for pain, and especially for evening and nighttime, indica strains are favored for their relaxing, sedative effect. A person without experience with THC should use caution and titrate slowly up to higher doses. Research as well as patient feedback have indicated that, in general, a ratio of 4: THC is the most effective for both neuropathic and inflammatory pain.
Each individual is different, however—for some, a 1: Chemotypes high in beta-caryophyllene, myrcene, and linalool provide additional pain relief and increase the effectiveness of other cannabinoids for analgesia. For relief of immediate symptoms, as in a flare-up of pain, vaporizing or smoking work well. The medication effect is immediate and lasts one to three hours, whereas most ingested products take thirty to sixty minutes before taking effect faster on an empty stomach and last six to eight hours.
Sublingual sprays or tinctures taken as liquid drops also take effect quickly and last longer than inhaled products. When pain is localized, topical products can be applied. Topicals affect the cells near application and through several layers of tissue but do not cross the blood-brain barrier and are, therefore, not psychoactive.
The skin has the highest amount and concentration of CB2 receptors in the body. Considering all of the studies together, which number over forty for various types of pain , CBD and cannabis are shown to have a rating of likely probable efficacy. It is one of the best-substantiated medical uses of cannabinoids. Sativex, a cannabis plant—derived oromucosal spray containing equal proportions of THC and CBD, has been approved in a number of countries for use to treat specific types of pain.
Numerous randomized clinical trials have demonstrated the safety and efficacy of Sativex for treatment of central and peripheral neuropathic pain, rheumatoid arthritis, and cancer pain. A study showed that CBD and CBC stimulated descending pain-blocking pathways in the nervous system and caused analgesia by interacting with several target proteins involved in nociceptive control. Sleep Disorders Insomnia, Sleep Apnea Cannabis and sleep have a complex relationship that is only beginning to be understood by science.
In general, for most people, indica strains are more relaxing and effective for sleep disorders, whereas sativa strains are more stimulating and tend to keep people awake.
Several studies conducted between and demonstrated the variable effect of different cannabinoids on sleep. Another study found CBD to be wake-inducing for most subjects, though some reported better sleep a few hours after taking it. However, a significant number of people find THC, even indica strains, will make the mind more active.
For these people, CBD oil can benefit them and tends to work well, providing the relaxation and calm for the mental as well as the physical body. For these people, CBD taken at nighttime as part of a bedtime regime produces a restful sleep, not the alertness produced in the daytime. This bidirectional effect of CBD is the result of balancing the endocannabinoid system.
In relation to sleep apnea, a animal study observed the ability of THC to restore respiratory stability by modulating serotonin signaling and reducing spontaneous sleep-disordered breathing.
