Originally a specialized herbal treatment, cannabidiol (CBD), a non-psychoactive chemical produced from Cannabis sativa, has become a popular health product in the last ten years. CBD is advertised for its ability to treat ailments including anxiety, chronic pain, sleeplessness, and epilepsy. It may be found as oils, candies, lotions, and even pet products. It is appealing because, in contrast to delta-9-tetrahydrocannabinol (THC), its psychoactive equivalent, it does not produce intoxication effects. However, worries regarding CBD’s effectiveness, safety, and potential for abuse are growing along with its usage. This article covers the Balancing Benefits with Abuse of CBD.
Knowing the Chemistry and Pharmacology of CBD
Among the more than 140 cannabinoids found in Cannabis sativa, a plant that has been utilized for thousands of years for therapeutic reasons, is CBD. CBD has a low affinity for CB1 and CB2 receptors in the brain, in contrast to THC, which binds directly to CB1 to generate bliss. Rather, it interacts with non-cannabinoid receptors such as serotonin 5-HT1A and transient receptor potential vanilloid 1 (TRPV1) and inhibits the breakdown of anandamide, an endogenous cannabinoid, to indirectly influence the endocannabinoid system. The possible medicinal benefits of CBD are supported by these interactions.
CBD’s bioavailability varies pharmacokinetically based on the method of administration. Due to first-pass metabolism in the liver, oral consumption has a bioavailability of 6–20%, but sublingual or inhalation routes have a greater absorption rate. The fact that cytochrome P450 enzymes (CYP2C19, CYP3A4) are the main enzymes that metabolize CBD raises questions about drug-drug interactions since it may change how drugs like antidepressants or antiepileptics are metabolized.
Balancing Benefits with Abuse of CBD
Although there is still a lack of solid clinical evidence for many conditions, the therapeutic potential of CBD has been thoroughly investigated. We examine some of its most promising uses, backed by research, below.
1. epilepsy
Lennox-Gastaut syndrome (LGS) and Dravet syndrome are two uncommon juvenile epilepsy diseases for which there is the greatest evidence of CBD’s effectiveness. For these disorders, the U.S. Food and Drug Administration (FDA) authorized Epidiolex, a pure CBD formulation, in 2018. In individuals with LGS and Dravet syndrome, Epidiolex decreased seizure frequency by 30–50%, with some patients experiencing total seizure cessation, according to randomized controlled trials (RCTs). CBD’s regulation of neuronal excitability via TRPV1 and GABA receptors is most likely the mechanism.
2. Fear
According to preclinical and clinical research, CBD may lessen anxiety via binding to 5-HT1A receptors. After four weeks of high-dose CBD therapy, individuals with moderate to severe social anxiety showed a 60–70% decrease in anxiety symptoms, according to a 2019 research published in Nature. According to a different study, taking 600 mg of CBD 90 minutes before to a public speaking exam considerably reduced anxiety when compared to a placebo. Effects, however, vary depending on the dosage and population; minor instances of anxiety may not improve at all or may even slightly increase.
3. Persistent Pain
CBD is a potential pain reliever due to its analgesic and anti-inflammatory qualities. Patients with moderate to severe symptoms reported much less pain after receiving CBD-rich therapies, according to a 2021 real-world evidence (RWE) research from a Canadian medicinal cannabis facility. According to preclinical research, CBD inhibits neuropathic pain by lowering pro-inflammatory cytokines like IL-6 and activating glycine receptors. However, there aren’t many RCTs on chronic pain, and the mixed outcomes call for further study.
4. Sleeplessness
By treating underlying problems like anxiety or chronic pain, CBD may enhance sleep. According to a 2019 research, 66.7% of subjects who used CBD (25–175 mg/day) for a month reported having improved sleep. Although there aren’t many long-term studies, CBD’s calming effects and interaction with 5-HT1A receptors may help induce and maintain sleep.
5. Mental illness
In small-scale clinical studies and preclinical models, CBD has shown antipsychotic effects. According to a 2012 research, individuals with acute psychotic schizophrenia who took 600–800 mg of CBD daily had less psychotic symptoms, perhaps as a result of dopamine activity modulation. Larger trials are required, however, since the effects are less noticeable in chronic schizophrenia.
6. Disorders of Substance Use
According to preliminary study, CBD may lessen withdrawal symptoms and cravings in drug use disorders, especially those involving opioids and cannabis. According to a 2019 study, those with heroin dependence who took 400–800 mg of CBD daily had less cue-induced cravings. These effects could be caused by CBD’s control of mesolimbic dopamine and anandamide levels.
CBD’s Safety Profile
According to the World Health Organization (WHO), pure CBD is typically harmless, shows no signs of dependency, and poses no serious dangers to public health. According to Epidiolex studies, common adverse effects include headache, nausea, diarrhea, and somnolence. But there are a few safety issues that need to be addressed:
Liver Toxicity: When taken with medications like valproate, high dosages of CBD (≥20 mg/kg) have been associated with abnormal liver function tests and, in rare circumstances, liver harm.
Drug Interactions: Because CBD inhibits CYP450 enzymes, it may raise the levels of drugs like warfarin or clobazam, which might have negative consequences.
Reproductive Toxicity: Research on animals indicates that CBD may decrease male testicular growth and sperm formation, which raises questions about long-term usage.
Unregulated Products: A lot of commercial CBD products have incorrect labels, contain different amounts of CBD, or are contaminated with toxic metals, pesticides, or THC.
According to a 2017 survey, just 30% of CBD products sold online had proper labels.
Concerns about Abuse: Does CBD Have an Addiction Potential?
CBD does not activate CB1 receptors, which are linked to pleasure and addiction, and it does not have psychotropic qualities like THC does. Human research demonstrating no withdrawal symptoms or reinforcing effects reinforced the WHO’s 2018 report’s conclusion that CBD has no risk for misuse or dependency. Even at large dosages, CBD has no potential for misuse, according to a 2020 meta-analysis.
But worries about abuse continue because:
Mislabeling and THC Contamination: THC, which has the potential to be abused, may be present in unregulated CBD products. Unintentional psychoactive effects or positive drug tests may result from this.
Risks of Self-Medication: Self-treating with CBD for unproven disorders may cause patients to put off obtaining evidence-based therapies, which might make their health problems worse.
Combination with Other Substances: Although the research is conflicting, CBD may increase or reduce the risk of dependency when taken with THC or other medications.
The landscape of laws and regulations
The legal position of CBD differs across the world and is complicated. Although hemp-derived CBD (less than 0.3% THC) was authorized in the US by the 2018 Farm Bill, the FDA insists that CBD cannot be sold as a food ingredient or dietary supplement without authorization. The FDA has authorized just Epidiolex, placing the majority of CBD products in a regulatory limbo. Different states have different rules; some permit the medicinal use of CBD with a greater THC concentration.
The 1961 UN Single Convention on Narcotic Drugs does not regulate CBD internationally, although national laws do. While CBD-rich medicinal cannabis is allowed in Canada under rigorous regulation, CBD-free CBD is lawful in the UK. Consumer uncertainty and problems with product quality are caused by regulatory loopholes.
Guidelines for Public Health
Evidence-based recommendations are essential for customers thinking about CBD:
Speak with a Healthcare Professional: To prevent drug interactions, talk to a doctor before using CBD, particularly if you are on medication.
Select Reputable Items: To confirm the amount of CBD and the lack of impurities, choose CBD products that have undergone independent laboratory testing.
Start modest, Go Slow: To monitor effects and adverse effects, start with a modest dosage (e.g., 10–25 mg/day) and titrate gradually.
Steer clear of unsupported claims: Because there is insufficient data, be wary of goods advertised for dubious illnesses like cancer or Alzheimer’s.
Particular Populations: Because of the possible hazards to fetal development, women who are pregnant or nursing should avoid CBD. Caution is necessary for the elderly and those with liver diseases.
