Many OCD-diagnosed individuals are turning to cannabidiol (CBD) in a bid to self-medicate. and whether or not CBD is a viable method for improving symptoms associated with OCD. Hemp Oil for Pain Anxiety Relief:: Hemp 10, The purpose of the current review is to determine CBD's potential as a treatment for anxiety-related disorders, by assessing evidence from preclinical, human. To offer a brief relief from the anxiety OCD causes, doctors generally treat this disorder with a combination of medications, such as anti-anxiety.

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.
