Pharmacist’s Guide to CBD Oil ABSTRACT: Cannabidiol (CBD) is becoming more prevalent, and pharmacists must be knowledgeable about these products in order to counsel patients effectively. CBD CBD, or cannabidiol, is a chemical compound just like any other substance on our beautiful planet. Just like any other compound, it has the potential to interact with other compounds, such as medications that metabolize in the same part of the body. Can CBD oil help treat hypertension? And is it safe to take with existing blood pressure medications?
Pharmacist’s Guide to CBD Oil
ABSTRACT: Cannabidiol (CBD) is becoming more prevalent, and pharmacists must be knowledgeable about these products in order to counsel patients effectively. CBD laws and regulations are determined at the state level in the United States. Non–FDA-approved CBD products are not regulated and may contain harmful chemicals. Pharmacists must counsel patients on where and how to obtain products and to check the amount of CBD and delta-9-tetrahydrocannabinol in the product. CBD has numerous drug interactions that should be evaluated by a pharmacist. CBD is most promising for treatment-resistant seizures, and more research is necessary to evaluate its use for other indications. Sativex is currently being investigated in the U.S. for treatment of spasticity associated with multiple sclerosis and schizophrenia. In general, more studies of CBD are needed.
Cannabidiol (CBD) is gaining popularity across the United States. Pharmacists must be able to answer patients’ questions about CBD and make recommendations. This article will provide specific information about CBD, including laws, how to select a non–FDA-approved CBD product, indications for use, side effects and warnings, drug interactions, dosing and directions, pharmacokinetics, and the future of CBD oil. After reading this article, pharmacists should feel confident about counseling patients about CBD and recommending CBD products.
Laws Concerning CBD
CBD was first isolated from the Cannabis sativa plant in the 1930s. CBD is a nonpsychoactive part of the plant, whereas delta-9-tetrahydrocannabinol (THC) is the major psychoactive part of the plant. In the 1970s, researchers evaluated CBD as a pharmacologic agent. 1 Epidiolex, a 100 mg/mL oral solution with less than 0.01% THC, became the first FDA-approved CBD-containing drug in June 2018. 2 The drug is Schedule V and indicated only as an anticonvulsant for Lennox-Gastaut syndrome or Dravet syndrome in patients aged 2 years and older. 3
In December 2018, the Agriculture Improvement Act, which removed hemp from Drug Enforcement Administration (DEA) regulation as a controlled substance, was passed and signed into U.S. law. Hemp is defined as a cannabis plant that contains no more than 0.3% THC. (In contrast, marijuana has a higher THC.) Hemp is now regulated by the U.S. Department of Agriculture and is legal in all 50 states. Laws and restrictions regarding the selling of hemp products vary by state, making it questionable to travel with CBD products. 2
U.S. laws and regulations concerning CBD are determined at the state level. Currently, 33 states have legalized CBD use for medical purposes, and 10 states (Alaska, California, Colorado, Maine, Massachusetts, Michigan, Nevada, Oregon, Vermont, and Washington) and the District of Columbia have legalized marijuana for recreational use. In states such as New York, Minnesota, and Connecticut, pharmacists are required to dispense the products in authorized dispensaries. Marijuana-derived CBD oil is still considered illegal under the Controlled Substances Act in accordance with the DEA’s classification of marijuana as a Schedule I substance. 2
Selecting a Non–FDA-Approved CBD Product
Pharmacists must educate patients about how to select an appropriate non–FDA-approved CBD product. These products are not tested for safety, efficacy, or quality. 4 The main concerns in picking a non–FDA-approved CBD product are that it may contain harmful chemicals and may not accurately list the correct amounts of CBD and THC it contains. These products could contain harmful contaminants (e.g., pesticides, heavy metals) or have high levels of THC, which would result in a positive urine drug test. 5 The patient should be advised to obtain CBD products from a medical dispensary because these products are regulated. The patient should also consider ordering products from states where CBD is legal because more testing is done in those states. When selecting a product, the patient should check the label to see if it lists the amount of CBD in each dose. 5,6 The manufacturer should provide a Certificate of Analysis, which shows an independent laboratory’s assessment of the product’s potency and the presence of contaminants. 5 When assessing quality, the patient should look for the Hemp Authority seal, which means that the product is legal and the manufacturer is adhering to quality standards. 7
Indications for CBD
As consumer demand in the U.S. has risen, along with the number of dispensaries, the number of studies addressing the therapeutic effects of CBD has increased. The studies performed, however, are insufficient; large randomized, placebo-controlled trials need to be conducted. CBD seems most promising for treatment-resistant seizures. There is limited evidence concerning the use of CBD for psychotic symptoms in Parkinson’s disease and for anxiety related to public speaking. CBD has not been proven effective for pain, nausea, or depression. 4 THC, conversely, is thought to be effective for these conditions because it has a different mechanism of action. THC activates the CB1 and CB2 receptors in the brain, and CBD does not. As mentioned previously, CBD does not have psychotropic effects and THC does. These differences are believed to account for the different uses of CBD and THC. 7,8
Patients with early-onset epilepsy who are resistant to conventional therapy may benefit from CBD oil. A trial that investigated the effect of CBD on drop seizures of Lennox-Gastaut syndrome found that CBD 10 mg/kg/day or 20 mg/kg/day, when added to conventional therapy, led to a greater reduction of drop seizures compared with placebo. 9 The most common adverse reactions were somnolence, decreased appetite, and diarrhea. Specific adverse events from CBD included elevated liver aminotransferase concentrations. 9
Clinical findings on the use of CBD oil in Parkinson’s disease (PD) remain unclear. Past studies have evaluated CBD’s efficacy in minimizing nonmotor symptoms of PD, such as cognitive deficits, sleep disturbances, psychosis, depression, and anxiety. 10 The neuroprotective properties of CBD have been studied in animals with PD, with results indicating that CBD appears to reduce psychotic symptoms. 11 Although patients with PD have reported fewer sleep disturbances as well as improvements in quality of life, treatment in humans requires further investigation on a larger scale, with longer durations and more standardized dosing. 12 Most studies have used combinations of CBD and THC extracts, including nabilone, a synthetic CB1 receptor agonist. CBD dosages of 150 mg/day for 4 weeks and titrated by 140 mg/week were found to be safe and well tolerated and did not worsen motor function. 10
More evidence is needed to support the use of CBD for anxiety. Studies have found that CBD 300 mg may be effective for anxiety related to public speaking, and doses of 400 mg to 600 mg may help patients with social anxiety disorder and public speaking–related anxiety. Studies are inconclusive concerning the utility of CBD for anxiety. 13
Side Effects and Warnings
Studies have reported various properties and potential benefits of CBD. Some undesired side effects of CBD use are decreased appetite, dry mouth, diarrhea, dizziness, drowsiness, fatigue, lightheadedness, orthostatic hypotension, psychomotor slowing, sedation, somnolence, weight loss, and increased risk of liver injury with dosages of 20 mg/kg/day or the use of clobazam or valproate. Monitoring of liver enzymes, weight, and cognitive function may be warranted. CBD can pass through the placenta, so it is recommended that CBD be avoided during pregnancy and while breastfeeding. Because CBD oils may contain trace amounts of THC, operating heavy machinery and driving should be avoided when treatment is initiated. 1
CBD is metabolized in the liver, mainly by CYP2C19, CYP3A4, and UGT. This can lead to interactions with prescription drugs, OTC medications, and herbal supplements. 1,14
The inhibition of CYP2C19 by CBD can increase levels of carisoprodol, citalopram, clopidogrel, diazepam, phenytoin, proton pump inhibitors (PPIs), valproic acid, and warfarin. As a strong CYP3A4 inducer, CBD may lessen the efficacy of amlodipine, atorvastatin, buprenorphine, bupropion, diltiazem, eplerenone, fentanyl, loperamide, midazolam, paclitaxel, pioglitazone, sildenafil, solifenacin, tamsulosin, testosterone, topiramate, zolpidem, and other 3A4 substrates. 7
More serious effects may occur with concomitant use of central nervous system depressants, such as barbiturates, benzodiazepines, fentanyl, morphine, and propofol. These effects are the result of the synergistic effects of sedation and hypnotic effects at high doses. Increased sedative effects may also be seen with herbal supplements, including kava, melatonin, S-adenosylmethionine, and St. John’s wort. 13,14
Other interactions to be aware of are presented in TABLE 1.
Dosing and Directions
In unregulated dispensaries, CBD oil sold comes in a sublingual formulation known as CBD tincture and is generally available in 30-mL bottles with dropper caps. 15 A bottle costs approximately $20. The concentration of the tincture ranges from about 1,500 mg to 3,000 mg per bottle. If a drop equals 0.05 mL, one bottle contains approximately 600 drops of CBD oil. Drops are usually placed under the tongue, and the patient should let the oil absorb into the lining of the mouth, without swallowing, for 30 seconds to 1 minute. Capsules and gummies are also available. 15
As noted earlier, Epidiolex (CBD) is an FDA-approved oral solution for treatment of seizures associated with Lennox-Gastaut syndrome or Dravet syndrome. The cost of Epidiolex is approximately $2,708 per month. It is supplied as 100 mL of solution containing CBD 100 mg/mL. For both indications, the initial starting dosage is 2.5 mg/kg orally twice daily for 1 week. The dosage may be titrated weekly in increments of 2.5 mg/kg twice daily to a maintenance dosage of 5 mg/kg twice daily. The maximum dosage is 10 mg/kg twice daily or 20 mg/kg/day. Gradual tapering is recommended when Epidiolex is discontinued. 3
Starting at a low dosage is recommended for elderly patients and patients with moderate or severe hepatic impairment. The dosage should be 1.25 mg/kg to 5 mg/kg twice daily or 0.5 mg/kg to 2 mg/kg twice daily, respectively. 3
CBD reaches its maximum concentration in 2.5 to 5 hours. High-calorie and high-fat meals can increase the maximum concentration of drug fivefold and the AUC fourfold. 14 Owing to the first-pass effect, CBD is poorly absorbed, with a bioavailability of 13% to 19%. Better bioavailability has been reported with inhaled CBD (11% to 45%). CBD is 94% protein bound; therefore, interactions may occur with other highly protein bound drugs or in patients who have abnormal albumin levels. The volume of distribution is 20,963 L to 42,849 L, meaning that the drug is largely distributed into the tissues. CBD is metabolized by the gut and primarily by the liver. Epidiolex has an active metabolite, 7-OH-CBD, and is a 2C19 and 3A4 substrate and inhibitor of 2C19, 1A2, UGT1A9, and UGT2B7. Its elimination half-life is 56 to 61 hours. CBD is excreted primarily in the feces and urine. 3
The Future of CBD
Sativex (nabiximols) is an oromucosal spray that contains CBD and THC in a 1:1 ratio. The active ingredients are absorbed sublingually or buccally. Sativex is currently under investigation in the U.S.; however, more than 25 countries worldwide have approved Sativex for the treatment of spasticity associated with multiple sclerosis. Sativex is also being researched for potential treatment of schizophrenia and other conditions. 16
The Pharmacist’s Role
Some pharmacists are hesitant to get involved with CBD. Prosecution by federal law could lead to severe consequences, including fines, imprisonment, or loss of DEA registration for pharmacies, ultimately stripping them of their ability to dispense controlled substances. If U.S. laws and regulations were more uniform across states, many of the concerns surrounding CBD would be eliminated. Until then, patients must use caution when selecting a product from an unregulated source because of the possibility of contamination and product misbranding. 17 Although more testing is needed, it is imperative for pharmacists to understand what to recommend to patients. Pharmacists should counsel patients on the risks and benefits of treatment. Patients who are are using CBD should be reminded to obtain the product from a reputable manufacturer. 17
Pharmacists need to keep abreast of current information on CBD in order to assist patients who are interested in using it. While most studies are inconclusive, there currently is enough information to effectively guide patients in choosing a treatment. CBD has the most evidence for treatment-resistant seizures; other indications need further study. Patients must be counseled to choose an appropriate product from a reputable source. CBD may be misbranded or contaminated with harmful chemicals. Pharmacists are uniquely positioned to assess the numerous potential drug interactions with CBD. New prescription CBD products are currently being investigated in the U.S.
What Drugs Should Not Be Taken With CBD?
CBD, or cannabidiol, is a chemical compound just like any other substance on our beautiful planet. Just like any other compound, it has the potential to interact with other compounds, such as medications that metabolize in the same part of the body. There are a whopping 98 identified drug interactions just for caffeine, some of which stop the other drug from working completely. Even grapefruit can’t be eaten if you’re on certain prescription medications – which means it’s no surprise that CBD and some drugs just shouldn’t mix.
Fortunately, unlike caffeine and grapefruit, most of the potential interactions with CBD and other drugs have been identified as harmless or mild. In some cases, other drugs and CBD can work in combination with each other favorably instead of having adverse side effects. We always recommend speaking with a certified health professional or physician prior to taking CBD oil or adding it into your daily routine, especially if you are currently on or plan on taking prescription medications. Today, though, we’re going to cover some of the drugs that have been shown to interact with CBD in some way to look at which drugs should not be taken with CBD.
How CBD Might Interact with Other Drugs
We see a range of ways for how CBD interacts with other drugs, medications, and chemical compounds. Cannabidiol may potentially reduce the metabolism of other drugs that compete for the same enzyme as it does. Metabolized by the cytochrome enzymes CYP2C19 and CYP3A4 in the body, this can raise the blood levels of other medications that metabolize the same way, which would require your doctor to do a downward adjustment on your doses. It can inhibit CYP2D6, the enzyme targeted by risperidone and omeprazole medications. Likewise, it could reduce the metabolization of diclofenac and warfarin by inhibiting the hepatic enzyme, CYP2C9.
It was found to increase the bioavailability of Hexobarbital, a barbiturate derivative with sedative and hypnotic effects that’s often sold in both sodium salt and acid forms like Tobinal, Evipan, and Citopan. While cannabis may increase the potency or effectiveness of other drugs, close monitoring by your physician or a medical professional is important. Your dosage may need to be adjusted even if the drug interact is beneficial, so make sure you’re staying honest with your doctor if you’re interested in using CBD.
The CYP450 Enzyme
CBD interacts with more than one cytochrome enzyme, including one located primarily in the liver and brain that’s involved in helping the body process about 60% of the pharmaceuticals on the market right now.
In short, cannabidiol has the potential to interact with a lot of medications just from this enzyme alone.
In fact, here are some of the drugs that have been shown to use the CYP450 enzyme system in our bodies:
· Oral hypoglycemic agents
· Calcium channel blockers
By interacting or saturating this enzyme system, CBD could potentially prevent other drugs from accessing the same enzyme. This causes those medications to build up in the bloodstream instead, which simply makes the drug more potent. However, it could also prevent medication from having a timely effect or releasing into the bloodstream when it’s expected to. On the bright side, just using CBD oil or another CBD product doesn’t mean that your CYP450 enzyme system is affected. Those results came from observing consistently high doses of CBD.
The lower dosages that come in a CBD oil tincture bottle will likely not cause the same extreme effects. We still need more research before we can find the exact dose of CBD required to make any significant difference for a drug interaction. As a rule of thumb, it’s safe to assume that the risk of drug interaction increases the more CBD you take in a daily sitting.
Serum Concentration Increase
CBD may cause an increase the amount of medication in your blood, otherwise known as serum concentrations, according to the District of Columbia’s Department of Health. Just like grapefruit, this means it may interact with beta blockers, calcium channel blockers, antiretrovirals, antihistamines, and antidepressants. Allergy pills, blood pressure medication, and even cholesterol drugs may absorb differently due to CBD blocking the liver enzyme it’s trying to metabolize through.
Again, this is only found in very high doses of CBD, some of which are stronger than an entire standard bottle of a CBD oil tincture. Low amounts of CBD such as standard serving sizes throughout the day don’t appear to affect how your body is processing other medicine (though a doctor’s second opinion is always recommended).
Timing Might be Everything
While you need to discuss with your physician the schedule for taking your drugs, some research suggests that the timing of when you take other medications and CBD might play a huge role in CBD’s interaction with those drugs. The goal is to reduce the workload of the liver. Medication that metabolizes in the liver enzymes are already causing the liver to perform its bodily function. However, all drugs have a half-life, and it doesn’t stay in your liver once it has been metabolized. You just have to wait long enough for the enzymes in your liver to regain a sufficient level of their function before using CBD oil. Drug interactions between CBD and other liver enzyme metabolizing medications may diminish after waiting a couple hours between taking your prescription medication and taking the cannabidiol. Your chances of a drug interaction could be lower by trying CBD throughout different times of the day.
Everyone processes CBD and other drugs differently, so you may experience different interactions than others or have little to no reaction even when you take medication in combination with cannabidiol. Heavily influenced by our body size, age, genetics, and sensitivity to chemical compounds, the effect medication will have and how our bodies will process it can vary greatly. This is just one of the reasons you want to speak with a certified health professional if you’re taking other medication to make sure it doesn’t interfere with a daily serving or more of cannabidiol.
The CBD Product You Choose Matters
There are a tremendous variety of CBD products available now – from CBD oil tinctures, to soft chews, to topicals, we see new products released every day for the industry. The way you decide to use CBD will contribute greatly to how it interacts with any medication you’re on. How much cannabidiol gets into the bloodstream varies from method to method.
For example, applying a topical CBD cream to a target area on the body, or maybe over a muscle spasm, means that the cannabidiol is only interacting with the CB receptors on the skin. The amount of CBD absorbed into the bloodstream topically is likely negligible, making it one of the safest options if you want to use CBD but don’t want it to interact with a more important prescription medication you’re taking. You can also ingest the cannabidiol directly through a CBD oil tincture, soft chew, or other edible product.
This reduces how much and how fast the CBD hits the bloodstream, taking the long route through the gastrointestinal system before heading to the liver to reach those important liver enzymes we keep talking about. Using this method to consume your CBD, you still lessen some of the CBD that’s absorbed into the enzymes in the liver. CBD oil sublingually is the second-best way to get the most effective dose possible. Swishing it around in your mouth, through your teeth, and substantially under your tongue will allow it to hit the highest surface count of capillaries. This is a direct route to your bloodstream, so you can expect the effects to hit the fastest and most effectively, lasting around the same amount of time as an edible might. While this is one of the best ways to get the most out of a CBD oil bottle, it also runs the chance of causing the CBD to interact most severely with any other medication.
The most direct route, an IV is the only way to get the CBD anymore directly into your bloodstream. However, you can also vape or smoke the product; some CBD oil formulas can even be used for both vaping and sublingual doses.
Don’t mix substances without receiving medical advice from a doctor first. We love seeing how many people have found the effectiveness of CBD daily, but your health is the most important factor. We use CBD to promote general wellness, so we want to be upfront about anything that substance might interact with.
Whether you’re taking your prescribed medications or you’re new to cannabidiol, speak with a certified health professional before you take your first serving. Alternatively, you can also check out our lab reports to feel more confident about the lack of contaminants and pollutants and accuracy of the cannabinoid content level we report. You can also check out the FAQ section for any other CBD related answers you are looking for.
In the meantime, we hope this answers any questions you had about how cannabidiol metabolizes in the body, how CBD interacts with other medications or prescription drugs, and, ultimately, which drugs should not be taken with CBD.
Blood Pressure Medication and CBD Oil Interaction
A growing number of Americans are turning to cannabidiol (CBD) to address a wide range of concerns from stress and anxiety, to pain and inflammation. But, with so many people using CBD oil, questions start to arise about potential interactions with common prescriptions, including blood pressure medications.
If you rely on blood pressure medication and want to use CBD oil as an alternative or supplement to your current treatment plan, here is an overview of everything you need to know about using CBD oil while taking blood pressure medications.
CBD Oil and Blood Pressure Medication Interaction
Because there are such a wide range of pharmaceuticals prescribed for lowering blood pressure, it’s impossible to speak in broad terms about how CBD oil interacts with them all. However, if you’re taking one of the more common medications for hypertension (valsartan, metoprolol beta blocker, lisinopril, amlodipine besylate, or hydrochlorothiazide), there are a few things you should take into consideration before using cannabidiol oil.
CBD oil is generally recognized as a safe and well-tolerated compound with little to no known side effects. However, while conclusive studies have not been published, it has been suggested that CBD oil may affect the efficacy of blood pressure medication in controlling hypertension. Conversely, blood pressure medication is also believed to potentially reduce the efficacy of CBD oil.
Furthermore, because cannabidiol is an inhibitor of the cytochrome P-450 enzyme system , CBD oil should be used cautiously when combined with medications that use this pathway; in the case of high blood pressure medications, metoprolol and amlodipine besylate specifically.
The cytochrome P-450 system is comprised of liver enzymes that break down medications into smaller substances that the body can more easily process. Cannabidiol and other natural substances like grapefruit slow down this pathway. This may cause medications that rely on the P-450 system, including metoprolol and amlodipine besylate, to remain for longer periods in the system and increase the likelihood that you experience their adverse side effects.
Side Effects of Using CBD Oil and Blood Pressure Medication
While adverse interactions between CBD oil and blood pressure medication are rare, they should be combined with caution and only under doctor supervision. In some cases, blood pressure medications may delay and/or reduce the beneficial effects of CBD oil. In others, CBD oil may delay and/or reduce the effectiveness of your prescribed blood pressure medication.
For reference, this table breaks down a few of the more common blood pressure medications and the side effects you may feel if taking them in conjunction with CBD oil.
|Generic Name (Brand Name)||Possible Side Effects of Combining Medication + CBD Oil|
|Valsartan (Diovan)||CBD oil may be metabolized slower when used in conjunction with Valsartan|
|Metoprolol (Lopressor; Toprol XL)||The antihypertensive function of Metoprolol may be decreased when combined with CBD oil|
|Lisinopril (Prinivil; Zestril)||The antihypertensive function of Lisinopril may be decreased when combined with CBD oil|
|Amlodipine besylate (Norvasc)||CBD oil may be metabolized slower when used in conjunction with Amlodipine besylate|
|Hydrochlorothiazide (HCTZ)||The antihypertensive function of Hydrochlorothiazide may be decreased when combined with CBD oil|
Another important thing to note is that since CBD oil reduces blood pressure on its own, when it is taken in tandem with medication designed to perform the same action, you essentially have two compounds bringing down your levels. If your blood pressure is reduced too much in a short amount of time, you may feel weak and lethargic. It is for this reason that starting with a small initial dosage of CBD is key.
Avoiding the Side Effects
With the above possible side effects in mind, you may feel dissuaded from trying CBD oil while on blood pressure medication. On the other hand, you might also consider using CBD oil on its own to manage hypertension. Amongst other benefits, CBD oil has been shown to reduce blood pressure by relieving anxiety, reducing stress, and widening blood vessels.
CBD oil’s anti-anxiety and stress-relieving properties encourage a lower heart rate, which ultimately reduces blood pressure. CBD oil’s ability to dilate blood vessels allows for easier blood flow in arteries with plaque build-up, which also reduces the symptoms of hypertension. In fact, a 2017 study found that a single dose of cannabidiol significantly lowered the blood pressure of test subjects both when at rest and in stressful conditions.
In a cumulative 2017 review of numerous studies on cannabidiol’s effect on blood flow, it was concluding that “ CBD may be used as a treatment for various cardiovascular disorders, such as hypertension, myocardial infarction, and stroke.” It is important to mention that the majority of these results were found in animal studies and more clinical research is needed in humans. Still, the findings are promising.
How to Safely Use CBD Oil and Blood Pressure Medication Together
Whether your goal is to supplement your current hypertension treatment plan with CBD oil, or to completely replace your blood pressure medication with CBD oil, you should begin by speaking with your doctor . Because CBD oil can interact with your current blood pressure medications, consulting with your physician on the possible risks—and benefits—is crucial for your safety and health.
You will want to be conscientious of dosage especially since CBD oil may amplify the effects of the medications you’re taking. CBD products generally come with an information leaflet that provides a recommended dosage, but you may want to start with an amount lower than what is recommended and gradually increase your dosage over time as needed. This will allow your body to build a tolerance to CBD oil and reduce the risk of having a sudden drop in your blood pressure.
For more information on proper CBD oil dosage, check out our dosage guide here .
Over a period of time, you may even find you are able to lower the dosage of your blood pressure medication as the CBD oil becomes most effective. If you choose to do this, speak to your doctor before discontinuing or altering your prescription medication. Any changes to your treatment plan are best done under the supervision and guidance of a medical professional.
If you’re still in need of guidance or would like more information on using CBD oil as a medical supplement, consider speaking with a naturopathic doctor who specializes in natural health treatments.
Best CBD Oil to Use with Blood Pressure Medication
In order to find the best CBD oil product, you need to know what you’re looking for. With thousands of products available online and in stores, how do you know where to start?
First, investigate the different CBD oil delivery formats to decide which one best fits your goals and lifestyle. CBD oil drops, edibles , capsules, and vapes a few of the more common options.
While the majority of people new to CBD oil opt for capsules and edibles because of their convenience and familiarity, it is worth keeping in mind that these will enter your body through the digestive system and therefore lose some potency and take longer before you feel the effects. Inhalants or sublingual drops meanwhile, allow the CBD oil to enter the bloodstream more readily, providing quick and effective results. Experiment with the different delivery methods to decide which works best for your needs and lifestyle.
Once you have decided on your preferred delivery format, look for top-rated CBD oil products that are sustainably sourced, organically grown, and third-party lab tested to ensure quality and purity. Taking these steps is the best way to ensure that your CBD oil product is free from any harmful pesticides, herbicides, and added chemicals.
