CBD-induced changes in metabolite profile and brain pharmacokinetics might change pharmacological effects. In 1995, CBD effects on THC pharmacokinetics were investigated in mice receiving 120 mg/kg IV CBD 2 h before 12 mg/kg IV THC . THC alone disturbed time estimations, increased pulse rate, and induced strong psychological reactions, while up to 60 mg CBD alone produced no effects. CBD AEs in humans listed in the Epidiolex® FDA approval notification and in Epidiolex® prescription information include decreased appetite, diarrhea, nausea, vomiting, and abdominal pain. Serious adverse events were reported in 30% patients, including one unexpected death regarded as unrelated to study drug. In a retrospective study of 74 children 1–18 years old with seizures, the CBD dose ranged from 1 to 20 mg/kg/day for more than 3 months (average 6 months) . In an online survey of 117 parents who administered CBD cannabis preparations to their children with uncontrolled epilepsy, the median dose was 4.3 mg/kg/day for a median duration of 6.8 months . The onset time for CBD gummies can vary, but typically, you may start to feel the effects within 30 to 60 minutes after ingestion. No, CBD gummies made from hemp will not cause a high as they contain less than 0.3% THC, which is not enough to produce psychoactive effects. It’s also important to note that the market’s lack of regulation can lead to products containing unwanted substances like THC, pesticides, or harmful bacteria. Listen to Your Body The results of the evaluation of pharmacokinetics, to see if interaction between the drugs occurred, were as follows. This extensive tool tests, for example, 78 adverse effects divided into 23 categories corresponding to organ systems or body parts. Adverse effects and safety were evaluated with both forms of the Systematic Assessment for Treatment Emergent Events (SAFTEE). A study, where a regimen of 6×100 mg CBD daily was coadministered with hexobarbital in 10 subjects, found that CBD increased the bioavailability and elimination half-time of the latter. The antibiotic rifampicin induces CYP3A4, leading to reduced CBD peak plasma concentrations.14 In contrast, the CYP3A4 inhibitor ketoconazole, an antifungal drug, almost doubles CBD peak plasma concentration. Effects of short-term cannabidiol treatment on response to social stress in subjects at clinical high risk of developing psychosis.Psychopharmacology (Berl). Evidence of a clinically significant drug-drug interaction between cannabidiol and tacrolimus. Food effect on pharmacokinetics of cannabidiol oral capsules in adult patients with refractory epilepsy. Massi, P., Vaccani, A., Ceruti, S., Colombo, A., Abbracchio, M. P., and Parolaro, D. Antitumor effects of cannabidiol, a nonpsychoactive cannabinoid, on human glioma cell lines. They hope that these products can increase pleasure, help libido, set the mood, relax muscles and ease performance anxiety. Typically, the higher the dose, the more unanticipated side effects. In addition to reducing anxiety and stress, CBD gummies can also help to improve sleep quality, which is essential for overall health and well-being. All of these can increase your risk of experiencing negative side effects from CBD gummies. Fortunately, there are things you can do to avoid the side effects of CBD or at least to reduce your chances of experiencing them. While the negative side effects of CBD gummies aren’t common for most consumers, they’re still a possibility. In a 2017, randomized, double-blind, placebo-controlled CBD trial on Dravet’s syndrome, 120 children received 20 mg/kg/day oral CBD or placebo for 14 weeks, in conjunction with their standard treatment (1 to 5 antiepileptic drugs) . Although there was one study that highlighted a potential liver problem in rats, the results of this study were based on the administration of impossibly high doses of pure CBD and human clinical studies have since addressed and quashed the concerns. For instance, the study mentioned above, where 23 children with Dravet syndrome were treated, increases as well as decreases in appetite and weight were observed as side effects.2 An open-label trial with 214 patients suffering from treatment-resistant epilepsy showed decreased appetite in 32 cases. In a placebo-controlled, randomized, double-blind study with 62 subjects with noninsulin-treated type 2 diabetes, 13 patients were treated with twice-daily oral doses of 100 mg CBD for 13 weeks. Fifteen neuroleptic-free patients with Huntington's disease were treated with either placebo or oral CBD (10 mg/kg b.w. per day) for 6 weeks in a double-blind, randomized, crossover study design. This might have an effect for coadministration of CBD with other drugs.7 For instance, CBD is metabolized, among others, via the CYP3A4 enzyme. A single dose of 600 mg led to reduced anxiety and mean CBD blood concentrations of 4.7–17 ng/ml.9 Using the pharmacokinetic relationships mentioned above, one would need to administer an oral CBD dose of 2100 mg CBD to affect ABCC1 and ABCG2. On the contrary, a 700 mg CBD oral dose reached a plasma level of 10 ng/ml.6 This means that to reach a 1 μg/ml plasma concentration, one would need to administer considerably higher doses of oral CBD. An open-label study of cannabis-based extracts for bladder dysfuntion in advanced multiple sclerosis. Long-term use of a cannabis-based treatment in spasticity and other symptoms in multiple sclerosis. Effects of ipsapirone and cannabidiol on human experimental anxiety. After 6 days of MK-801 treatment, various CBD doses were injected intraperitoneally (15, 30, 60 mg/kg) for 22 days. Schiavon et al. cite three studies that used chronic CBD administration to demonstrate its anxiolytic effects in chronically stressed rats, which were mostly mediated via hippocampal neurogenesis.19 and references therein For instance, animals received daily i.p. CBD treatment of up to 14 days (3–30 mg/kg b.w. i.p.) did not affect blood pressure, heart rate, body temperature, glucose levels, pH, pCO2, pO2, hematocrit, K+ or Na+ levels, gastrointestinal transit, emesis, or rectal temperature in a study with rodents.1 In contrast, phenobarbital, rifampicin, carbamazepine, and phenytoin induce CYP3A4, causing reduced CBD bioavailability.11 Approximately 60% of clinically prescribed drugs are metabolized via CYP3A4.1Table 1 shows an overview of the cytochrome inhibiting potential of CBD. What are the Side Effects of CBD? "CBD gummies can be a useful tool for managing menstrual cramps, anxiety, and stress," says Dr. John Doe, a specialist in women's health. CBD has been shown to have a range of effects on the body, including reducing anxiety and stress, which can be significant barriers to sexual enjoyment. In addition to pain relief, CBD gummies can also help to reduce anxiety and stress, which are common issues for many women. CBD is a non-psychoactive compound found in the cannabis plant, which has been shown to interact with the body's endocannabinoid system to produce a range of potential benefits. Rats were treated for 14 days with various CBD concentrations (15, 30, 60 mg/kg daily i.p.). Various studies on CBD and psychosis have been conducted.20 For instance, an animal model of psychosis can be created in mice by using the NMDAR antagonist MK-801. Applying a 5HT1A receptor antagonist in the DPAG (dorsal periaqueductal gray area), it was implied that CBD exerts its antipanic effects via these serotonin receptors. Carbamazepine (Tegretol) interacts with Cannabidiol (CBD) When starting a CBD gummies regimen, it’s important to stick to the recommended starting dose for two to three weeks before increasing to higher doses. It can take up to two weeks, or even longer, for some people to experience the desired beneficial effects of CBD. Many of the negative side effects of CBD gummies were most often observed in individuals who were taking a very high CBD dosage. By only purchasing CBD gummies from a trusted source that uses third-party lab tests and makes the results available to its customers, you can reduce your risk of experiencing adverse side effects. Many people around the world are benefiting from the therapeutic effects of cannabidiol, with little or no adverse side effects at all. Shockingly, a 2017 study examined the contents of 84 CBD products from 31 companies and found that just over 30% of the products were labeled correctly. It’s worth noting that the doses given to these mice were the equivalent of a 175lb human taking around 200,000mg in one single dose or 50,000mg of CBD per day for several days. The observed effect lasted for 2 weeks after CBD administration and could normalize the changes seen after stimulus cue-induced heroin seeking (expression of AMPA, GluR1, and CB1R).In addition, it is important to reflect whether the medication is safe for each individual based on his or her health, age, genetics, chronic illnesses, and other medications (due to the problem of drug-drug interactions).No effect was evident for urinary CBD and metabolite excretion except at the higher fentanyl dose, in which CBD clearance was reduced.Effects of cannabidiol on amphetamine-induced oxidative stress generation in an animal model of mania.And the drugs could make side effects that CBD can cause even worse.Treatment occurred using IP injections of 1 or 5 mg/kg CBD, three times a week for 3 weeks (including 1 week before carcinogen administration).These include known side effects of CBD, but also unintended interactions with supplements, herbal products, and over-the-counter (OTC) and prescription medications.Generally, more human studies, which monitor CBD-drug interactions, are needed. CBD Safety and Side Effects Following 90 days of oral CBD ( mg/kg/day), liver and kidney weights in rhesus monkeys were 13-56% greater than controls, without morphological changes in the organs . In a study on the efficacy of CBD in schizophrenia, there was a low incidence (≥4%) of mild AEs including somnolence and insomnia, with a frequency similar to that found in placebo . Treatment-related AEs, including somnolence, were mostly mild and occurred in 62% of 86 patients treated with 20 mg/kg/day CBD for 14 weeks. In conjunction with other antiepileptic drugs, seizure frequency was reduced compared to placebo. The validated subjective measures scales Anxiety (visual analog scale VAS), PANAS (positive and negative subscores), and OVAS (specific opiate VAS) were administered across eight time points for each session without any significant main effects for CBD for any of the subjective effects on mood.10 No correlation was found between CBD dose and plasma cortisol levels. No effect was evident for urinary CBD and metabolite excretion except at the higher fentanyl dose, in which CBD clearance was reduced. Peak CBD plasma concentrations of the 400 and 800 mg group were measured after 4 h in the first session (CBD administration 2 h after light breakfast). These contaminants are then passed onto the consumers, who may experience various adverse health effects as a result. Even though that amount of THC is very low and wouldn’t cause a person to feel “high” (like medical cannabis would), it’s still enough to possibly trigger a positive drug test result. Although these studies were performed in mice with huge doses of CBD, which aren’t comparable to supplement doses of CBD found in gummies, it’s important for consumers to be aware of this risk. In 1974, Karniol et al. investigated effects of oral 0, 15, 30, and 60 mg CBD alone, 0 and 30 mg THC alone, and CBD and THC combinations to study potential drug-drug interactions in a double-blind trial in 40 healthy male volunteers . In a study with a total of 21 Parkinson's patients (without comorbid psychiatric conditions or dementia) who were treated with either placebo, 75 mg/day CBD or 300 mg/day CBD in an exploratory double-blind trial for 6 weeks, the higher CBD dose showed significant improvement of quality of life, as measured with PDQ-39. In a 2017, double-blind, randomized, placebo-controlled CBD trial on Dravet’s syndrome, 120 children and young adults received 20 mg/kg/day oral CBD or placebo for 14 weeks, along with standard treatment of 1 to 5 antiepileptic drugs . These products have not been approved by the FDA and are not intended to diagnose, treat, cure, or prevent any disease. Online resource that provides a thorough, objective and fresh perspective on delicate topics that deal with cannabis use. The effects of CBD gummies can last between 4 to 6 hours, depending on the dosage and the individual’s metabolism. In humans receiving the drug for the treatment of epilepsies and psychiatric disorders, the most common AEs included tiredness, diarrhea, nausea, and hepatotoxicity. In many of the preclinical studies, much higher CBD concentrations were administered. It is important that physicians and patients understand that CBD, like any other medication, is not appropriate for every individual and every disease and that it has side effects that are not negligible and must be considered prior to use.

The 2018 Farm Bill made it legal to buy CBD products containing less than 0.3% THC under federal law. Because the FDA currently does not regulate CBD, there are no specific recommended doses. Not much research has looked specifically at CBD and fertility, and most studies have been in animals, not people. There is limited research on how CBD interacts with prescription drugs and with standard over-the-counter supplements. The Ultimate Guide to CBD Gummies: Benefits, Dosage, and Side Effects This could improve patients' compliance and adherence to treatment.Known as cannabinoids, CBD and delta-9-tetrahydrocannabinol (THC) are different chemicals found in cannabis.In January 2019, the World Health Organization (WHO) changed position after 60 years and proposed rescheduling of cannabis and cannabinoids for therapeutic purposes 54, 55.Guimaraes FS, Chairetti TM, Graeff FG, Zuardi AW.It has to be pointed out though, that the in vitro studies used supraphysiological CBD concentrations.Testing shows purity and dosage can be unreliable in many products.However, widespread prohibition resulted in a massive shift in attitudes towards cannabis, despite its wide-reaching therapeutic potential.Acute supplementation with cannabidiol does not attenuate inflammation or improve measures of performance following strenuous exercise. The only exception seems to be a multicenter open-label study with a total of 162 patients aged 1–30 years, with treatment-resistant epilepsy. After extensive literature study of the available trials performed until September 2016, CBD side effects were generally mild and infrequent. Another clinical study lasting at least 3 months with 137 children and young adults with various forms of epilepsy, who were treated with the CBD drug Epidiolex, was presented at the American Academy for Neurology in 2015. Epileptic patients were treated for 135 days with 200–300 mg oral CBD daily and evaluated every week for changes in urine and blood. A press release by GW Pharmaceuticals of September 15th, 2015, described 88 patients with treatment-resistant schizophrenic psychosis, treated either with CBD (in addition to their regular medication) or placebo. While many people use CBD products without experiencing significant issues, some may encounter side effects. While CBD gummies and oil are generally considered safe, it’s important to be aware of potential side effects and interactions. Www.arthritis.org/living-with-arthritis/pain-management/chronic-pain/arthritis-foundation-cbd-guidance-for-adults.php. Cannabinoid delivery systems for pain and inflammation treatment. A behavioral comparison of acute and chronic Delta9-tetrahydrocannabinol and cannabidiol in C57BL/6JArc mice. Cannabidiol as a potential treatment for psychosis. Multiple mechanisms involved in the large-spectrum therapeutic potential of cannabidiol in psychiatric disorders. Activation of 5HT1A receptors mediates the anxiolytic effects of cannabidiol in a PTSD model. Effects of cannabidiol and diazepam on behavioral and cardiovascular responses induced by contextual conditioned fear in rats. If you've ever experienced the “highs” that come with taking most cannabis products, you may have also experienced the munchies at some point. But if you've recently been struggling with your sleep, you can take a healthy dose to set you up for a quality night's rest. And while there are some potential side effects to look out for while using it, many of them are mild and will probably not be too much of a concern. It makes sense that midlife women reported cannabis improves anxiety, mood, and sleep, Dr. Hirsch says. Of those, 67% said cannabis helps with sleep disturbance, while 46% reported it helps improve mood and anxiety. So far, there’s not much evidence on the medical benefits of CBD, partly because laws on marijuana made it difficult to study.We do not know the effects of CBD on children's developing brains.Another study of 84 CBD products bought online showed that more than a quarter of the products contained less CBD than stated.Many women have reported positive experiences with CBD gummies for anxiety relief, citing benefits such as reduced anxiety and improved mood.Neuroprotective and blood-retinal barrier-preserving effects of cannabidiol in experimental diabetes.In these cases, your doctor may want to change the dose, or other precautions may be necessary.Currently, CBD is the focus of mass marketing campaigns and the subject of anecdotal reports claiming that CBD provides the answer for multiple illnesses from chronic pain to depression. In 2018, the cultivation of industrial hemp was made legal on a federal level, resulting in a surge of new CBD products. In this article, we'll discuss these possible negative side effects of CBD gummies as well as their potential benefits. While CBD gummies are generally well tolerated and considered safe to use, just as with any supplement, it’s important to be aware of any potential negative side effects. The antibiotic rifampicin induces CYP3A4, leading to reduced CBD peak plasma concentrations.14 In contrast, the CYP3A4 inhibitor ketoconazole, an antifungal drug, almost doubles CBD peak plasma concentration.Thrombocytopenia in pediatric patients on concurrent cannabidiol and valproic acid.AEs were reported in 6 patients following 20 mg/kg/day CBD, one following the lower dose, and one receiving a placebo.The dose of this medicine will be different for different patients.The list contains a variety of drugs from heart medications to antibiotics, although not all the drugs on the list may be affected by CBD-only products (some are only affected by THC).This was followed by a single 0.5 (Session 1) or 1.0μg/kg (Session 2, after 1 week of first administration to allow for sufficient drug washout) intravenous fentanyl dose. CBD use around the world is expanding for diseases that lack scientific evidence of the drug’s effi-cacy. You may report side effects to the FDA at FDA-1088. Call your doctor for medical advice about side effects. After rhesus monkeys received 150, 200, 225, 250, or 300 mg/kg IV CBD for 9 days, higher CBD doses elicited hypopnea, bradycardia, and cardiac failure . Treatment-related AEs were mostly mild and occurred in 62% of 86 patients treated with 20 mg/kg/day CBD for 14 weeks, including pyrexia in patients with Lennox-Gastaut syndrome, with concomitant clobazam, valproate, lamotrigine, levetiracetam, or rufinamide . In children and adults with treatment‐resistant epilepsies receiving up to 25‐50 mg/kg/day for a median 48-week duration, 33% experienced severe AEs including pneumonia . If you are thinking about trying CBD products, you might be curious about the side effects of CBD in elderly people. Research is still needed on larger cohorts of CBD patients, and evaluation of CBD effects following long-term exposure on genotoxicity and cytotoxicity, hormones, and the immune system are needed. The length of treatment is another important factor because data on AEs is much more limited following chronic CBD administration. Overall, the incidence of these occurrences is low and, in comparison with other drugs employed for the treatment of these diseases, CBD has a better side effect profile. "By understanding how CBD works and how it can be used to support women's health, individuals can make informed decisions about whether CBD gummies are right for them." According to experts in the field of CBD and women's health, CBD gummies can be a useful tool for addressing a range of health concerns. Many CBD gummies contain additional ingredients, such as melatonin or valerian root, which can enhance the effects of CBD. Importantly, fentanyl coadministration did not produce respiratory depression or cardiovascular complications during the test sessions and CBD did not potentiate fentanyl's effects. Generally, more human studies, which monitor CBD-drug interactions, are needed. Gov.49 In the following chapter, we highlight recent, acute clinical studies with CBD. Fasinu et al. created a table with an overview of clinical studies currently underway, registered in Clinical Trials. It’s also important to note that the market’s lack of regulation can lead to products containing unwanted substances like THC, pesticides, or harmful bacteria.Products containing cannabidiol (CBD) seem to be all the rage these days, promising relief from a wide range of maladies, from insomnia and hot flashes to chronic pain and seizures.Oral 0, 50, 80, or 125 mg/kg/day CBD administration during organogenesis in pregnant rabbits decreased fetal body weights and increased fetal structural variations were shown following the highest dose .Although not all of these side effects may occur, if they do occur they may need medical attention.WebMD does not provide medical advice, diagnosis or treatment.Apart from reducing the seizure frequency in 39% of the patients, the side effects were only mild to moderate and included reduced/increased appetite, weight gain/loss, and tiredness.It's legal for CBD products to have up to 0.3% THC, but the CDC warns that mislabeled CBD products may contain higher doses of THC, which can increase the risk of side effects.When starting a CBD gummies regimen, it’s important to stick to the recommended starting dose for two to three weeks before increasing to higher doses.Clinicians should be aware of CBD AEs and potential drug-drug interactions prior to recommending off-label CBD. It’s important to start with the recommended dose when taking CBD. For this reason, it may be better to take CBD gummies at the end of the day rather than in the morning. This side effect seems to be more common in those who smoke CBD as opposed to those who take oral CBD (like CBD gummies). It is possible that some consumers will experience the negative side effects of CBD gummies, though, so it’s important to be aware of what those may be. The largest CBD study conducted thus far was an open-label study with Epidiolex in 261 patients (mainly children, the average age of the participants was 11) suffering from severe epilepsy, who could not be treated sufficiently with standard medication. In this study, almost 50% of the patients experienced a reduction of seizure frequency. Apart from reducing the seizure frequency in 39% of the patients, the side effects were only mild to moderate and included reduced/increased appetite, weight gain/loss, and tiredness. Moreover, electrocardiograms as well as routine blood parameters were other parameters whose effects were measured but not reported in the study. Oral doses of 150–400 mg/day CBD (in the last week) were administered. CBD oil and gummies offer potential benefits for various health concerns, but it’s crucial to be aware of potential side effects.Signals called endocannabinoids — similar to cannabis plant molecules — activate our CB1 and CB2 receptors.If you notice any other effects, check with your healthcare professional.Many CBD gummies contain additional ingredients, such as melatonin or valerian root, which can enhance the effects of CBD.Apart from updating the literature, this article focuses on clinical studies and CBD potential interactions with other drugs.A randomized, controlled trial of ZYN002 cannabidiol transdermal gel in children and adolescents with fragile X syndrome (CONNECT-FX).More trials are underway to find out how CBD can help improve tremor and motor symptoms of Parkinson's disease Medications changed by the liver (Cytochrome P450 2B6 (CYP2B substrates) interacts with Cannabidiol (CBD) Some had far less CBD than advertised and some also contained illegal amounts of delta 9 THC (the psychoactive compound in cannabis that is responsible for making you feel high). Reputable CBD providers will pay for their products to be batch-tested by third-parties and will display results on their websites. The only CBD companies you should consider will be able to produce certificates of analyses (CoAs) that prove that their products are clean and safe to ingest. The real dangers of CBD lie in the fact that you are buying your products from an unregulated market, which is why it’s absolutely vital that you find a trustworthy and reliable supplier. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding. There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. For non-prescription products, read the label or package ingredients carefully. Many CBD products are unregulated, so it's best to buy products from a licensed dispensary or talk to your doctor about how to use them. CBD is a nonpsychoactive chemical found in the cannabis plant. If there's any THC in a CBD product that you use, then you could test positive for THC and fail a drug test. But it's not uncommon for CBD products to be mislabeled, so they could contain more THC than you think. But Dr. Hirsch wasn't surprised by the high proportion reporting regular cannabis use. More than 84% of participants reported smoking cannabis, while 78% consumed marijuana edibles, and nearly 53% used vaping oils. Perimenopausal women reported worse menopausal symptoms than their postmenopausal peers, as well as greater cannabis use to address their symptoms. Participants were split on whether they used cannabis for medical reasons, recreational purposes, or both. The new Harvard-led survey, published in the journal Menopause, looked at patterns of cannabis use in 131 women in perimenopause — the often years-long stretch before periods cease — along with 127 women who had passed through menopause. Cannabidiol as a potential treatment for febrile infection-related epilepsy syndrome (FIRES) in the acute and chronic phases. Cannabidiol as a new treatment for drug-resistant epilepsy in tuberous sclerosis complex. Interactions between cannabidiol and commonly used antiepileptic drugs. Trial of cannabidiol for drug-resistant seizures in the Dravet Syndrome. Individuals should be careful to not mistake THC products for hemp or CBD products. Many businesses that sell hemp and CBD products also sell products that contain THC. If you use products that contain CBD or THC, keep them in childproof containers and out of the reach of children. In a 4-week open trial, CBD was tested on Parkinson's patients with psychotic symptoms. The coadministration led to an alteration of blood levels of several antiepileptic drugs. These results are supported by another study described in the review by Grotenhermen et al.63 In this study, 33 children were treated with a daily dose of 5 mg/kg CBD, which was increased every week by 5 mg/kg increments, up to a maximum level of 25 mg/kg. Moreover, the only acute study that also measured CBD effect on appetite was the study we described above, comparing different cannabis strains. To the best of our knowledge, no acute studies were performed that solely concentrated on CBD glycemic effects. The non-psychoactive cannabis-constituent cannabidiol is an oral anti-arthritic therapeutic in murine collagen-induced arthritis. Effects of intracisternal administration of cannabidiol on the cardiovascular and behavioral responses to acute restraint stress. Cannabidiol reduces the anxiety induced by simulated public speaking in treatment-naïve social phobia patients. Trembly B, Sherman M. Double-blind clinical study of cannabidiol as a secondary anticonvulsant. Cell migration Women who are new to CBD may want to start with a lower potency product and gradually increase the dose as needed. This can be especially beneficial for women who experience pain or discomfort during sex, as CBD can help to reduce these negative sensations and promote a sense of enjoyment. In addition to reducing anxiety and stress, CBD gummies can also help to improve intimacy, by promoting a sense of connection and closeness. This can be especially beneficial for women who experience anxiety or stress related to their menstrual cycle or other hormonal changes. Attributing the side effects to CBD is also not straightforward in severely sick patients. Ten percent of the patients reported side effects (tiredness, diarrhea, and exhaustion).2 After 3 months of treatment, where patients received CBD together with their regular medication, a median reduction of seizure frequency of 45% was observed. Cannabidiol Adverse Effects and Toxicity Single-dose kinetics of deuterium-labelled cannabidiol in man after smoking and intravenous administration. The safety of CBD in the geriatric population has not been fully clarified, and Epidiolex clinical trials did not include patients older than 55 years.7 CBD formulations used in clinical trials include oral capsules, sublingual spray, oil-based solution, and topical gel. A recent survey revealed that one in seven Americans uses CBD products, with the most common reasons for its use being pain, anxiety, poor sleep, and arthritis.3 CBD products, which have become popular in the United States, are frequently used to treat pain, anxiety, and sleep disorders—conditions that affect older adults. Bergamaschi et al. list an impressive number of acute and chronic studies in humans, showing CBD safety for a wide array of side effects.1 They also conclude from their survey, that none of the studies reported tolerance to CBD. Compared to other anticonvulsant drugs, this effect was minimal.48 Unfortunately, we could not find more studies solely focusing on genotoxicity by other research groups neither in animals nor in humans. For instance, in ob/ob mice (an animal model of obesity), 4-week treatment with 3 mg/kg (route of administration was not mentioned) increased the HDL-C concentration by 55% and reduced total cholesterol levels by more than 25%. Chronic administration (14 days, 2.5 or 5 mg/kg i.p.) reduced the weight gain in rats. The high CBD concentration led to a significant decrease in polyps and a return to near-normal levels of phosphorylated Akt (elevation caused by the carcinogen).42 No adverse effects were mentioned in the described study.43 If you are taking other medications, CBD can impact their efficacy, and your doctor may need to reevaluate the dose you are taking. A small number of people who took higher doses of CBD had elevated liver enzymes, but no symptoms or jaundice. You can also ask staff questions about products, how they work, and which ones might work best for you. Their products are tested in labs for contamination and clearly labeled with CBD dosage. In January 2019, the World Health Organization (WHO) changed position after 60 years and proposed rescheduling of cannabis and cannabinoids for therapeutic purposes 54, 55. Moreover, CBD was shown to have low abuse liability 50, 51 and to be effective in decreasing cannabis addiction 52, 53. CBD improved subicular and CA1 subfields volumes in the brains of chronic cannabis users, suggesting a protective role of CBD against brain structural harms conferred by chronic cannabis use . CBD could help your cat with pain and anxiety. The bottom line is to talk with your health care provider about the CBD products you are taking and be completely honest about your dosing. And the drugs could make side effects that CBD can cause even worse. Because CBD might slow how your body breaks down these drugs, that could mean higher levels of the drug in your body, and even cause more side effects. In addition, it is important to reflect whether the medication is safe for each individual based on his or her health, age, genetics, chronic illnesses, and other medications (due to the problem of drug-drug interactions). CBD clearly has great potential as a new pharmacotherapy based on novel mechanisms of action for currently unmet clinical needs. Several studies defining CBD’s beneficial effects were included to provide balance and aid the readers’ ability to weigh risk/benefit. Clinicians should be aware of CBD AEs and potential drug-drug interactions prior to recommending off-label CBD. Recently, Solowij et al. described a 10-week study of daily 200 mg CBD in cannabis dependence to improve psychological symptoms and cognition . The physiological parameters, heart rate and blood pressure, were also monitored and no significant difference between the placebo and the CBD group was observed.55 The 600 mg CBD corresponded to mean (standard deviation) whole blood levels of 0.36 (0.64), 1.62 (2.98), and 3.4 (6.42) ng/mL, 1, 2, and 3 h after administration, respectively. In addition, no effects on peripheral cardiovascular measures such as heart rate and blood pressure were measured.54
