Jul 27, It is possible to add CBD oil to food, and an increasing amount of evidence generalized anxiety disorder, and post-traumatic stress disorder. Jun 5, From Generalized Anxiety Disorder (GAD) to PTSD and other specific phobias, studies suggest that CBD can have this same effect on all.
CBD Benefit How Disorders Can Anxiety-Related
Nobody likes the feeling of being anxious, but it actually is a normal feeling inherent in all of us. Anxiety is a critical adaptive response that helps humans cope with threats to our safety and general welfare.
Anxiety helps us avoid potential threats and then can often help motivate us to take a wiser course of action. So, we all suffer a little from anxiety. But many of us have difficulty managing the natural responses effectively and become maladaptive.
Severe anxiety has negative effects on our jobs, our familial relationships and our ability to socialize. In the United States alone, roughly 40 million adults — 18 percent of us — suffer from anxiety-related disorders. While many Americans leave this ailment untreated, those that do seek treatment tend to medicate with pharmaceuticals.
Selective serotonin reuptake inhibitors SSRIs — such as Prozac and Zoloft — are common for a growing adult population. Pharmaceutical tranquilizers and benzodiazepines — such as Valium and Xanax — are also gaining traction to treat anxiety disorders. Although there are fewer studies on cannabidiol specifically, the preliminary research is promising. A small study found that cannabidiol could reduce symptoms of social anxiety in people with social anxiety disorder SAD.
Brain scans of participants revealed changes in blood flow to the regions of the brain linked to feelings of anxiety. In this study, cannabidiol not only made participants feel better but also changed the way their brains responded to anxiety. A study also found that cannabidiol could reduce social anxiety. For that study, researchers looked specifically at cannabidiol to treat anxiety associated with public speaking. Research published in found that CBD oil had anti-anxiety and antidepressant effects in an animal model.
A analysis of previous studies concluded that CBD oil is a promising treatment for numerous forms of anxiety, including social anxiety disorder, panic disorder, obsessive-compulsive disorder , generalized anxiety disorder, and post-traumatic stress disorder. The report cautioned, however, that data on long-term use of CBD oil is limited.
While research strongly points to the role of cannabidiol in treating short-term anxiety, little is known about its long-term effects, or how it can be used as a prolonged treatment. A case study explored whether cannabidiol could reduce symptoms of post-traumatic stress disorder PTSD and anxiety-provoked sleep disorder in a child with a history of trauma. Researchers found that cannabidiol reduced the child's anxiety and helped her sleep.
Research on the use of cannabis suggests that it may have negative health effects, particularly when smoked. Research specifically on cannabidiol, however, has found few or no negative side effects. This means CBD oil may be a good option for people who do not tolerate the side effects of other medications for anxiety, including addiction.
Not all states in the United States have specifically legalized CBD oil, although some have legalized it for only specific purposes. A person should educate themselves about the potential risks of purchasing or using it.
Because CBD oil is not regulated as a medical treatment for anxiety, it is unclear what dosage a person should use, or how frequently they should use it. A person should consult a doctor who has experience with CBD oil to determine the right dosage for their needs. The role of cannabidiol as a treatment for anxiety disorders remains unclear, as more long-term studies are required to assess the benefits and risks. For people with anxiety who have gotten no relief from other treatments, however, CBD oil offers a potential alternative solution.
People considering CBD oil for anxiety should speak with a doctor to help determine the right treatment for them. People are also advised to research the laws in their area regarding the use of cannabis products. CBD oil is available for purchase online. Is it risky to take CBD oil for anxiety while it has not been approved for this use? The use of marijuana is becoming more common, but that does not guarantee it is safe, or free of contaminants or other drugs.
There has been acute poisoning reported from synthetic cannabinoids. For people with anxiety, CBD oil may provide relief. However, they must balance the benefit with legal risk and the risk of adverse effects. But trace amounts would not have much influence on mood or interfere with anxiety.

Cannabidiol reduces the anxiety induced by simulated public speaking in treatment-naive social phobia patients. Neuropsychopharmacology , 36 6 , Cannabidiol as a potential treatment for anxiety disorders [Abstract]. Neurotherapeutics , 12 4 , Regarding conditioned fear, the effect of CB 1 R activation is complex: CB 1 R activation may enhance or reduce fear expression, depending on brain locus and the eCB ligand [ 34 ]; however, CB 1 R activation potently enhances fear extinction [ 35 ], and can prevent fear reconsolidation.
Genetic manipulations that impede CB 1 R activation are anxiogenic [ 35 ], and individuals with eCB system gene polymorphisms that reduce eCB tone—for example, FAAH gene polymorphisms—exhibit physiological, psychological, and neuroimaging features consistent with impaired fear regulation [ 36 ].
Reduction of AEA—CB 1 R signaling in the amygdala mediates the anxiogenic effects of corticotropin-releasing hormone [ 37 ], and CB 1 R activation is essential to negative feedback of the neuroendocrine stress response, and protects against the adverse effects of chronic stress [ 38 , 39 ]. Accordingly, CB 1 R activation has been suggested as a target for anxiolytic drug development [ 15 , 43 , 44 ].
In addition to dose-dependent activation of TRPV1 channels, the anxiogenic versus anxiolytic balance of CB 1 R agonists also depends on dynamic factors, including environmental stressors [ 33 , 49 ].
In preclinical studies, 5-HT 1A R agonists are anxiolytic in animal models of general anxiety [ 51 ], prevent the adverse effects of stress [ 52 ], and enhance fear extinction [ 53 ]. They are expressed on serotonergic neurons in the raphe, where they exert autoinhibitory function, and various other brain areas involved in fear and anxiety [ 54 , 55 ].
Mechanisms underlying the anxiolytic effects of 5-HT 1A R activation are complex, varying between both brain region, and pre- versus postsynaptic locus, and are not fully established [ 56 ]. Initial studies of CBD in these models showed conflicting results: When tested over a wide range of doses in further studies, the anxiolytic effects of CBD presented a bell-shaped dose—response curve, with anxiolytic effects observed at moderate but not higher doses [ 61 , 90 ].
All further studies of acute systemic CBD without prior stress showed anxiolytic effects or no effect [ 62 , 65 ], the latter study involving intracerebroventricular rather than the intraperitoneal route. No anxiogenic effects of acute systemic CBD dosing in models of general anxiety have yet been reported.
As yet, few studies have examined chronic dosing effects of CBD in models of generalized anxiety. Anxiolytic effects in models used: Anxiolytic effects of CBD in models of generalized anxiety have been linked to specific receptor mechanisms and brain regions. The midbrain dorsal periaqueductal gray DPAG is integral to anxiety, orchestrating autonomic and behavioral responses to threat [ 91 ], and DPAG stimulation in humans produces feelings of intense distress and dread [ 92 ].
The bed nucleus of the stria terminalis BNST serves as a principal output structure of the amygdaloid complex to coordinate sustained fear responses, relevant to anxiety [ 93 ]. In the prelimbic cortex, which drives expression of fear responses via connections with the amygdala [ 94 ], CBD had more complex effects: As noted, CBD has been found to have a bell-shaped response curve, with higher doses being ineffective. Stress is an important contributor to anxiety disorders, and traumatic stress exposure is essential to the development of PTSD.
In a chronic study, systemic CBD prevented increased anxiety produced by chronic unpredictable stress, in addition to increasing hippocampal AEA; these anxiolytic effects depended upon CB 1 R activation and hippocampal neurogenesis, as demonstrated by genetic ablation techniques [ 81 ].
Finally, CBD, partially via CB 1 Rs, decreased defensive immobility and explosive escape caused by bicuculline-induced neuronal activation in the superior colliculus [ 89 ]. Several studies assessed CBD using contextual fear conditioning. Briefly, this paradigm involves pairing a neutral context, the conditioned stimulus CS , with an aversive unconditioned stimulus US , a mild foot shock. After repeated pairings, the subject learns that the CS predicts the US, and subsequent CS presentation elicits freezing and other physiological responses.
By contrast, CBD microinjection in the infralimbic cortex enhanced conditioned freezing [ 70 ]. Finally, El Batsh et al. In this study, CBD was administered prior to conditioning rather than prior to re-exposure as in acute studies, thus further directly comparable studies are required.
CBD has also been shown to enhance extinction of contextually conditioned fear responses. Extinction training involves repeated CS exposure in the absence of the US, leading to the formation of a new memory that inhibits fear responses and a decline in freezing over subsequent training sessions.
Further studies showed CB 1 Rs in the infralimbic cortex may be involved in this effect [ 82 ]. CBD also blocked reconsolidation of aversive memories in rat [ 76 ].
Briefly, fear memories, when reactivated by re-exposure retrieval , enter into a labile state in which the memory trace may either be reconsolidated or extinguished [ 97 ], and this process may be pharmacologically modulated to achieve reconsolidation blockade or extinction. Overall, existing preclinical evidence strongly supports the potential of CBD as a treatment for anxiety disorders. 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.
