Low levels of brain serotonin, a neurotransmitter, are involved in depression and anxiety. And — being a promiscuous molecule — CBD doesn’t just work its magic on cannabinoid receptors. CBD’s purported effects there — such as calming us down and helping us nod off at night — are all controlled by evolutionarily ancient brain systems that regulate vital functions such as appetite, emotion, fear and sleep. “Based on animal work in the bone marrow, CBD is likely to have effects on cells of the immune system such as macrophages to reduce the release of pro-inflammatory cytokines, which cause pain,” Professor Martin said. CBD may alleviate some of the distress experienced in chronic pain, although exactly how it does this isn’t clear.
Cannabidiol as an Intervention for Addictive Behaviors: A Systematic Review of the Evidence
Inhaled CBD (400 µg/inhalation) was effective to reduce the number of cigarettes smoked after one week of treatment. Nevertheless, CBD treatment did not attenuate nicotine craving and showed only a slight, non-significant reduction in anxiety after the 7 days treatment (Morgan et al., 2013). A few years later, the administration of a single dose of CBD (800 mg) in non-treatment seeking, dependent, cigarette smokers after overnight abstinence did not improve verbal or spatial working memory, or impulsivity (Hindocha et al., 2018). However, the same group demonstrated that CBD (single 800 mg dose) reduced attentional bias after a period of tobacco abstinence without improving craving or withdrawal (Hindocha et al., 2018). Recently, a preclinical study was conducted to analyze the effects of CBD (10 and 30 mg/kg) in mice exposed to an animal model of pharmacologically precipitated nicotine withdrawal. Interestingly, CBD abolishes memory impairment and microglial reactivity induced by nicotine withdrawal (Saravia et al., 2019).
- Interestingly, CBD abolishes memory impairment and microglial reactivity induced by nicotine withdrawal (Saravia et al., 2019).
- Interestingly, the results reported by our group in an animal model of spontaneous cannabinoid withdrawal support the implementation of randomized controlled trials (RCT) using only CBD.
- Ethanol consumption and preference were significantly reduced by CBD in a dose-dependent manner.
- According to the findings from preclinical and clinical studies, CBD alone or in combination with commonly employed treatment strategies in drug addiction may configure a potential therapeutic option for improving the dishabituation process of addicted patients.
- A 2017 study found that CBD products containing THC may decrease the time needed to fall asleep.
Risks and side effects
They play an important role in a wide range of functions including sleep, pain, appetite, mood, and the immune system. Dopamine is a neurotransmitter that plays an important role in mood and pleasure. By triggering a higher-than-normal release of dopamine, THC causes people to experience feelings of euphoria. THC is often administered by smoking marijuana, but it can also be found as an ingredient in capsules, edibles, tinctures, and oils.
Health Benefits of CBD Oil — and a Look at Side Effects
It contributed data to estimates of event rates but did not contribute data to the calculation of OR. This meant that 12 trials using data from 803 participants contributed data to the meta-analysis. When those who were not using cannabis at the time of our first survey later started using cannabis, they showed improvements in those same health measures that mirrored the differences between the cannabis users and nonusers in the beginning. The serotonergic system has a pivotal role in the modulation of motivational and reinforcement processes and is involved in the regulation of the rewarding effects of certain drugs of abuse.
Because THC has psychoactive effects, it may produce more immediate pain relief. However, CBD can help reduce inflammation, which is useful for long-term effectiveness. Some evidence suggests that taking both CBD and THC may provide the greatest pain relief. In one study, people who took a combination of CBD and THC experienced greater pain relief than those who took THC alone.
Analysis of studies
- Adamczyk et al. have further found that SB366791, a TRPV1 antagonist, reverses cocaine-induced reinstatement of previously extinguished cocaine-seeking behavior.
- When you spend time with a loved one or eat a delicious meal, your body releases a chemical called dopamine, which makes you feel pleasure.
- Also, another publication showed that CBD (5 and 10 mg/kg, i.p.) did not attenuate the motivation to self-administer cocaine (breaking point) nor the cue-induced cocaine seeking in rats after a withdrawal period (Mahmud et al., 2017).
- CBD significantly reduced the preference for the cocaine-context and the consolidation of cocaine memory.
- Cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC) are two types of cannabinoids derived from cannabis.
- Nonetheless, the data obtained on the final treatment day verify that the CBD formulation produced dose-dependent CBD plasma levels and significant brain concentrations.
Preliminary evidence suggests that CBD may help treat substance use disorder. In 2018, the Food and Drug Administration (FDA) approved Epidiolex, the first pure-CBD anti-seizure treatment. The FDA approved Epidiolex for treating rare forms of epilepsy, including Dravet syndrome and Lennox-Gastuaut syndrome. In a 2018 clinical trial, 72 is cannabidiol addictive children and 60 adults with treatment-resistant epilepsy received 5–50 milligrams per kilogram of body weight (mg/kg) of CBD daily. It’s important to know more about the substances your provider prescribes or the products within your household. After using a substance frequently, your body gets used to having it around all the time.
- Advocates say medicinal cannabis offers effective relief when other treatments are failing.
- The endocannabinoid system is involved in regulating functions like pain sensation.
- It was proposed that CBD could act as a partial agonist (Tham et al., 2019), inverse agonist or even as an antagonist (Thomas et al., 2007).
- Five human studies were found, but the sample sizes of the majority of these were small, and only two of them were randomized, double-blind studies.

In the context of reinstatement, cocaine-induced reconsolidation and priming-induced reinstatement remained unchanged following CBD (10 mg/kg) treatment (Chesworth and Karl, 2020; Luján et al., 2018). However, in other studies, CBD at different doses blocked priming- and stress-induced reinstatement of cocaine in mice (Calpe-López et al., 2021) and the reconsolidation of propensity for environment-paired cocaine in rats (De Carvalho and Takahashi, 2017). Regarding METH abuse, CBD administration during the extinction period (80 mg/kg; IP) (Hay et al., 2018) or at the time of the reinstatement (10 μg/5 μL; ICV) inhibited reinstatement of METH-induced CPP (Karimi-Haghighi and Haghparast, 2018) (Table 1).
Effects of CBD
Unlike THC, CBD is a negative allosteric modulator of cannabinoid type 1 (CB1R) and 2 (CB2R) receptors (Laprairie et al., 2015; Martínez-Pinilla et al., 2017) (Fig. 1). The role of CB1R in substance abuse disorders is controversial and may depend upon the phase of drug abuse (Galaj et al., 2020; Parker et al., 2004). Recent advances focused on the study of the molecular basis that underlies the neurogenesis promoting actions of CBD in relation with the regulation or drug reward. Lujan et al. described https://ecosoberhouse.com/ that CBD increased neural progenitor proliferation in the HIPP of cocaine self-administering animals. They explored the activation of MAPK pathway and its downstream pathways that regulate the expression of the transcriptional (CREB) and neurotrophic (BDNF) factors, responsible for the levels of neuronal hippocampal proliferation. Interestingly, the administration of CBD up-regulated ERK1/2 and CREB phosphorylation, as well as BDNF expression in the HIPP of mice that underwent cocaine SA.
Paper subject to independent expert blind peer review by minimum of two reviewers. This journal is a member of the Committee on Publication Ethics (COPE). Given these unknowns, as well as cannabidiol’s ability to slow your liver’s ability to metabolise other drugs, anyone considering taking CBD should speak to a medical professional first, no matter the claims you see pushed by influencers. With little current evidence that low-dose CBD has much medical benefit, he added, it may be years before the first CBD products appear on your pharmacist’s shelves.
In summary, we have ahead of us an exciting race to discover how CBD could contribute to the area of drug addiction from a therapeutic point of view. More preclinical and clinical studies are necessary to further evaluate the role of CBD as a new therapeutic intervention for SUD. The clinical studies that are currently underway will provide relevant information to improve our knowledge about the efficacy and safety of CBD for the treatment of SUD. These effects may be related, at least in part, with CBD-mediated improvement of withdrawal symptoms and the reduction of alcohol consumption, motivation, and relapse. Similarly, Ren et al. showed a reduction of CB1R gene and protein levels in the NAcc core and shell subregions of rats exposed to a cue-induced heroin seeking procedure.
