Anxiety Oil 2. CBD For
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.

As a rule, CBD oil extracted from hemp will contain no more than 0. CBD oils extracted from hemp generally fall into one of the following three categories: The vast majority of CBD oils come in bottles measuring either 15 milliliters mL , or 0. However, CBD concentration is more important than bottle size. Concentration refers to the ratio of hemp oil solution measured in mL compared to the amount of CBD cannabinoid measured in milligrams, or mg.
A mL bottle may contain mg of CBD, mg, mg, or more. The higher the mg amount, the stronger the CBD oil will be. How much CBD oil you should take largely depends on your bodyweight, as well as the desired effects. The next table breaks down the effects of different doses based on these two factors.
Always consult your physician to determine the best dosage for you. CBD oil alleviates physical pain and anxiety — both of which can have a negative impact on sleep. Additionally, CBD oil can actually prolong sleep for some, leading to more rest from night to night. However, please note that the medicinal effects of CBD oil have not been studied extensively. While many medical patients claim the oils improve sleep quality and duration, more clinical trials are needed to determine how and why these improvements occur — and if they are applicable to all individuals.
Additionally, CBD oil is also associated with some negative side effects. CBD oil is considered therapeutic and low-risk for most users. However, CBD oil may result in the following adverse effects: This may be the desired effect. In recent years, the legality of CBD oil and other products derived from hemp or marijuana has been a hot-button issue. Historically, hemp could legally be grown and cultivated for academic research purposes only.
However, the legality of hemp growth has changed in the past year. In April , Sen. Mitch McConnell of Kentucky introduced the Hemp Farming Act of , a piece of legislation that proposed legalizing all hemp products at the federal level.
Per the farm bill, industrial hemp will be descheduled as a federally controlled substance. Still, the legality of marijuana-based CBD oil also varies from state to state. The table below lists general guidelines for hemp- and marijuana-based CBD oil consumption based on different state laws.
These states have more complex laws pertaining to hemp- and marijuana-based CBD oils. These initiatives may have a bearing on the legality and availability of CBD oils. Three other states, Arizona, Missouri, and Nebraska, failed to garner enough votes to place marijuana initiatives on the ballots.
These laws are ever-changing, and the guidelines listed above should not substitute for legal advice. When purchasing hemp-derived CBD oil for sleep, you may be able to find products through one or more of the following establishments: Cost is another consideration. Most CBD oils are sold in concentrations of to mg, although this may range from less than mg to more than 2, A good indicator of price-point is the cost per milligram.
Low-cost CBD oils usually fall between five and 10 cents per mg; mid-range prices are 11 to 15 cents per mg; and higher-end oils cost 16 cents per mg or higher. Although price may be an indicator of CBD oil quality, we suggest researching the following factors to ensure the oil you select is considered high-quality.
Some forms of CBD oil — such as vapors and tinctures — normally have higher-than-average concentrations, whereas sprays and topicals tend to have lower concentrations. When buying CBD oil for the first time and comparing different products, here are a few variables to keep in mind: As noted in the previous section, CBD oil prices vary significantly by brand. The best practice for most is to determine a per-milligram budget for CBD oil, as well as a maximum price for the entire bottle.
Also, if ordering online, be sure to include potential shipping costs. Weight plays a role in the effects of CBD oil, and bottle size should be selected based on how much you weigh. If you weigh more than pounds and desire strong effects, then this same concentration will supply roughly 10 doses.
Also, state residence may indicate that fewer buying locations are available. If the answer is yes, then full spectrum CBD oils may not be a feasible option due to their THC content; although these oils contain trace amounts of THC, this may lead to a failed drug test. Crystalline isolate oils, on the other hand, contain no THC and will not compromise drug tests in any way. Third-party testing information is vital for consumers; any CBD oils that do not supply these details should be avoided.
Lab results are not as crucial, but may indicate a higher-quality product if they are included. Both online and brick-and-mortar experiences carry pros and cons for CBD oil shoppers. In addition to natural, unscented CBD oils, many oils come in different flavors.
This factor boils down to personal preference — although the flavor selection will be broader with some brands than others. How Does Marijuana Affect Sleep?

Crystalline Isolate Oil is extracted from cannabis plant, then allowed to cool; this isolates the CBD from other cannabinoids The oil forms crystals and is crushed into a powder None White and twinkly No Full Spectrum Oil Oil is extracted from the cannabis plant Oil is not cooled, allowing it to retain THC and other cannabinoids 0.
CBD oil can be consumed in several different ways. CBD oils may be manufactured as small capsules that are orally ingested. Another form of oral CBD oil ingestion is the tincture, often used as a food additive.
Tinctures are sold in dropper bottles; most users place one or two drops beneath their tongue for several minutes in order to experience the full effects. Tinctures normally have stronger concentrations compared to other CBD products. CBD oil can be ingested as an oral spray. Sprays tend to have lower concentrations compared to other CBD products. This form of CBD oil is applied directly to the skin; it usually has the consistency of lotion. Weight Group Recommended Dosage for Mild Effects Recommended Dosage for Moderate Effects Recommended Dosage for Strong Effects Light less than pounds 11 mg or less 12 to 14 mg 15 to 17 mg Medium to pounds 18 mg or less 15 to 23 mg 18 to 28 mg Heavy more than pounds 23 mg or less 24 to 30 mg 29 to 45 mg.
The anxiety-alleviating and sleep-prolonging qualities of CBD oil make it a good option for many people with insomnia. Those who experience insomnia due to pain or discomfort may also find that using CBD oil alleviates their physical symptoms to a noticeable extent. CBD oil may also promote daytime wakefulness when taken in small amounts; people with insomnia can use it as a pick-me-up if they feel excessively tired due to lack of restful sleep.
REM behavior disorder RBD is a parasomnia disorder characterized by shouting, becoming physically agitated, or otherwise acting out during sleep. Both depression and anxiety disorder have been linked to sleep disruption.
CBD oil can alleviate symptoms of these disorders because it activates serotonin receptors in the brain; the release of serotonin has soothing, anti-anxiety effects that can help people sleep. CBD oil also increases levels of adenosine in the brain; adenosine is a neurotransmitter that aids cardiovascular function and eases painful inflammation.
CBD oil may be prescribed for patients with Lennox-Gastaut syndrome or Dravet syndrome, two rare forms of severe epilepsy; the medication Epidiolex, a CBD oil oral solution, is typically prescribed in these instances. CBD oil can also ease the severity of seizures for people with other forms of epilepsy. Due to its anti-psychotic effects, non-THC CBD oil can reduce the symptoms of schizophrenia and other disorders with psychotic effects. The liver regulates the way different drugs are metabolized within the body; this process is known as hepatic drug metabolism.
Higher-than-average doses of CBD oil can slow the hepatic drug metabolism process. As a result, users may not be able to process other drugs as quickly. This is particularly concerning for CBD oil users who also take prescription medications. As is the case with many other hemp- and marijuana-based products, CBD oil often leads to a condition known as dry mouth or cottonmouth. This is likely due to cannabinoids altering receptors in the lower jaw that trigger salivation.
In most cases, mild discomfort and stronger-than-average thirst are the only issues associated with dry mouth. CBD oil may incite a small drop in blood pressure immediately after it is consumed; this may also cause the user to feel lightheaded.
Diarrhea is a common side effect for people who take relatively large doses of CBD oil, and is linked to the substance interacting with the digestive system. Lowering oil doses often minimizes this effect. CBD oil may make users feel hungrier than usual, which is a common effect of most cannabinoids.
Marijuana-based CBD oils are illegal to use recreationally or for medical reasons. The state senate recently introduced legislation that would legalize CBD oil, but the governor struck down this motion.
Marijuana-based CBD oil is illegal to use recreationally, but is available to medical patients participating in a clinical trial. Hemp-based CBD is legal. Marijuana-based CBD oil is illegal to use recreationally, but is legal for research purposes when used to treat epilepsy.
