Cannabidiol (CBD) oil is an extract from hemp plants called Cannabis indica and Cannabis sativa . You might be more familiar with cannabis plants because they are grown for marijuana. However, CBD is not the same thing as marijuana.

CBD oil contains CBD that’s mixed with a base (carrier) oil, like coconut oil or hemp seed oil. These are called tinctures. You can get tinctures in different concentrations. The oil can also be put into capsules, gummies, and sprays.

People who support using CBD oil say that it can treat pain and anxiety; can help stimulate appetite and may help manage some types of seizures.

This article goes over what CBD is used for, the possible side effects, and what you should look for if you choose to buy CBD.

CBD vs. Marijuana

CBD is one component (called a cannabinoid ) that’s found in a hemp plant. Marijuana is a separate plant but it’s from the same species that hemp belongs to. Marijuana has CBD and hundreds of other compounds in it.

The main difference between hemp plants and marijuana plants is how much of a compound called tetrahydrocannabinol (THC) is in them. Hemp is grown to have less than 0.3% THC, while marijuana has more.

THC is what’s responsible for the psychoactive effects of cannabis—in other words, it’s what makes you feel “high.”

CBD oil generally does not have THC in it; however, a very small (trace) amount might be in products sold in certain states.

What Is CBD Oil Used For?

We’re not sure exactly how CBD works. Unlike THC, CBD doesn’t have a strong connection with the molecules in the brain that THC binds to create psychoactive effects. These are called cannabinoid receptors.

Instead, CBD works on other receptors, like the opioid receptors that help control pain. It also affects glycine receptors that control a brain chemical called serotonin which helps control your mood.

People that support the use of CBD claim that CBD oil can treat a variety of health problems, including:

  • Acne
  • Anxiety
  • Chronic pain
  • Depression
  • Drug use and withdrawal
  • High blood pressure
  • Muscle spasms
  • Poor appetite

As CBD has gained popularity, researchers have been trying to study it more. Still, there has not been a lot of clinical research to look for evidence in support of these health claims.

CBD is not a safe option for everyone. Talk to your healthcare provider if you want to try it for managing a health condition.

Anxiety

A 2015 review of research that was published in the journal Neurotherapeutics suggested that CBD might help treat anxiety disorders.

The study authors reported that CBD had previously shown powerful anxiety-relieving effects in animal research—and the results were kind of surprising.

In most of the studies, lower doses of CBD (10 milligrams per kilogram, mg/kg, or less) improved some symptoms of anxiety, while higher doses (100 mg/kg or more) had almost no effect.

The way that CBD acts in the brain could explain why this happens. In low doses, CBD might act the same as the surrounding molecules that normally bind to the receptor that “turns up” their signaling.

However, at higher doses, too much activity at this receptor site could produce the opposite effect.

There have not been many trials to look at CBD’s anxiety-relieving effects in humans. However, one was a 2019 study published in the Brazilian Journal of Psychiatry.

For the study, 57 men took either CBD oil or a sugar pill with no CBD in it (placebo) before a public-speaking event.

The researchers assessed the participants’ anxiety levels using measures like blood pressure and heart rate. The researchers also used a reliable test for mood states called the Visual Analog Mood Scale (VAMS).

The men who took 300 mg of CBD oil reported less anxiety than the men who were given a placebo; however, the men who took 100 mg or 600 mg of CBD oil did not experience the same effects.

Addiction

CBD oil might help people with substance use disorder, according to a 2015 review published in the journal Substance Abuse.

The review looked at the findings from 14 published studies. Nine of the studies looked at the effects of CBD on animals, and five studies looked at the effects on humans.

The researchers reported that CBD showed promise for treating people with opioid, cocaine, or psychostimulant use disorders.

However, the effects of CBD were quite different depending on the substance. For example, CBD without THC did not decrease withdrawal symptoms related to opioid use.

On the other hand, it did reduce drug-seeking behaviors in people using cocaine, methamphetamine, and other similar drugs.

Some experts suggest that CBD could help treat cannabis and nicotine dependence, but more research is needed to provide this theory.

High Blood Pressure

A 2017 study found that CBD oil may reduce the risk of heart disease because it can lower high blood pressure in some people.

For the study, nine healthy men took either 600 mg of CBD or the same dose of a placebo. The men who took CBD had lower blood pressure before and after experiencing stressors like exercise or extreme cold.

The study also looked at the amount of blood remaining in the heart after a heartbeat (stroke volume).

The stroke volume in the men who took CBD was lower than in was in the placebo group, meaning their hearts were pumping more efficiently.

The study suggested that CBD oil could be a complementary therapy for people with high blood pressure that is affected by stress and anxiety.

However, there is no evidence that CBD oil can treat high blood pressure on its own or prevent it in people at risk. While stress can complicate high blood pressure, it does not cause it.

Seizures

In June 2018, the U.S. Food and Drug Administration (FDA) approved a CBD oral solution called Epidiolex.

Epidiolex is used to treat two rare forms of epilepsy in children under the age of 2: Dravet syndrome and Lennox-Gastaut syndrome. These are very rare genetic disorders that cause lifelong seizures starting in the first year of life.

Other than for these two disorders, CBD’s effectiveness for treating seizures is not known. Even with Epidiolex, it’s not clear if the anti-seizure effects are from CBD or another factor.

However, there is some evidence that CBD interacts with seizure medicines like Onfi (clobazam) and raises their concentration in the blood. That said, more research is needed to understand the link.

Possible Side Effects

Clinical research has shown that CBD oil can cause side effects. The specific side effects a person has and how bad they are varies from one person to the next and from one type of CBD to another.

Some common side effects people report from using CBD include:

  • Anxiety
  • Changes in appetite
  • Changes in mood
  • Diarrhea
  • Dizziness
  • Dry mouth
  • Nausea
  • Vomiting

CBD oil may also increase liver enzymes, which is a marker of liver inflammation.

People with liver disease should talk to their healthcare provider before taking CBD oil. They may need to have their liver enzymes checked regularly if they are using CBD.

Can You Use CBD If You’re Pregnant?

You should not use CBD oil if you’re pregnant or breastfeeding. Even though the effects of CBD are not fully understood, it does pass through the placenta.

The American Academy of Pediatrics (AAP) further states that pregnant people should not use marijuana because of the potential risks to a developing fetus.

Do not drive or use heavy machinery when taking CBD oil—especially when you first start using it or switch to a new brand. Remember that some products do contain THC, even in small amounts.

Interactions

CBD oil can interact with medications, including many that are used to treat epilepsy. One of the reasons for this has to do with how your body breaks down (metabolizes) drugs.

Cytochrome P450 (CYP450) is an enzyme your body uses to break down some drugs. CBD oil can block CYP450. That means that taking CBD oil with these drugs could make them have a stronger effect than you need or make them not work at all.

Drugs that could potentially interact with CBD include:

  • Anti-arrhythmia drugs like quinidine
  • Anticonvulsants like Tegretol (carbamazepine) and Trileptal (oxcarbazepine)
  • Antifungal drugs like Nizoral (ketoconazole) and Vfend (voriconazole)
  • Antipsychotic drugs like Orap (pimozide)
  • Atypical antidepressants like Remeron (mirtazapine)
  • Benzodiazepine sedatives like Klonopin (clonazepam) and Halcion (triazolam)
  • Immune-suppressive drugs like Sandimmune (cyclosporine)
  • Macrolide antibiotics like clarithromycin and telithromycin
  • Migraine medicine like Ergomar (ergotamine)
  • Opioid painkillers like Duragesic (fentanyl) and alfentanil
  • Rifampin-based drugs used to treat tuberculosis

Always tell your healthcare provider and pharmacist about all the medicines you take, including prescription, over-the-counter (OTC), herbal, or recreational drugs.

The interactions between these medications and CBD are often mild and you might not have to change your treatment.

However, in some cases, you might have to change medications or space out your doses to avoid a reaction. That said, never change or stop medication without talking to your provider.

Dosage and Preparation

There are no guidelines for using CBD oil. Each product works a bit differently, depending on the form.

For example, putting the oil under your tongue can produce effects more quickly than swallowing a capsule that needs to be digested.

Here are a few ways that you can take CBD oil:

  • Placing one or more drops under your tongue and holding it there for 30 to 60 seconds without swallowing. You can also use a spray that is spritz in your mouth/under your tongue.
  • Taking a capsule or chewing a gummy

There’s no “correct” dose of CBD oil. How much you take and the form you choose will depend on your needs and what you hope to get for effects. The average dose range is from 5 mg to 25 mg.

Most oils come in 30-milliliter (mL) bottles and include a dropper cap to help you measure.

That said, it’s hard to figure out the exact amount of CBD per milliliter of oil. Some tinctures have concentrations of 1,500 mg per 30 mL, while others have 3,000 mg per mL or more.

How to Calculate CBD Dose

To determine an exact dose of CBD, remember that each drop of oil equals 0.05 mL of fluid. This means that a 30-mL bottle of CBD oil will have about 600 drops in it.

If the concentration of the tincture is 1,500 mg per mL, one drop would have 2.5 mg of CBD in it. The math to figure that out looks like this: 1,500 mg ÷ 600 drops = 2.5 mg

What to Look For

CBD oil comes in different forms: isolates, broad-spectrum, and full-spectrum.

  • Isolates contain only CBD
  • Broad-spectrum oils nearly all of the components of the plan (e.g., proteins, flavonoids, terpenes, and chlorophyll), but does not have THC oils have all the compounds including THC (up to 0.3%)

Alternative medicine practitioners believe that the compounds provide more health benefits, but the is a lack of evidence to support these claims.

Remember that CBD oils are unregulated. There’s no guarantee that a product is what it claims to be on its packaging. You also can’t know for sure that it’s safe and effective.

A 2017 study reported that only 31% of CBD products sold online were correctly labeled. Most had less CBD in them than was advertised, and 21% had significant amounts of THC.

If you are interested in buying CBD products, here are a few tips to keep in mind:

  • Buy American: Domestically produced CBD oil might be a safer option than those that have been imported.
  • Go organic: Brands certified organic by the U.S. Department of Agriculture (USDA) are less likely to expose you to pesticides and other harmful chemicals.
  • Read the product label: Even if you choose a full-spectrum oil, don’t assume that every ingredient on the product label is natural. CBD products can also have preservatives, flavorings, or thinning agents in them. If you don’t recognize an ingredient, ask the dispenser what it is or check online.

Summary

Hemp plants can be grown for different purposes. Some species are made for marijuana but others are used to make CBD products.

Unlike marijuana, CBD oil does not “get you high.” Instead, it may help relieve stress, anxiety, drug withdrawals, and nerve pain.

While there are many claims about the health benefits of using CBD oil, the evidence is lacking. A lot of studies were done with animals, not humans.

If you want to try CBD oil, you should learn about the different dosages and preparations first.

You should also know that the products are not regulated, which means you can’t know for sure that a product will work and be safe.

Before you use CBD oil, talk to your provider. If you take certain medications or have a health condition, you may not be able to use these products.

Frequently Asked Questions

It would be hard to overdose on CBD oil. Research has shown that human tolerance for CBD is very high. One study reported the toxic dose would be about 20,000 mg taken at one time.

It depends on where you live, the type of product, how it was sourced (e.g., is it from hemp or marijuana), and its intended purpose (medical or recreational). In many states, you must be 18 or 21 to buy CBD oil. Check your state’s laws.

Not necessarily. While the names are sometimes used interchangeably, hemp oil can also refer to hemp seed oil, which is used for cooking, food production, and skincare products.

CBD oil is made from the leaves, stems, buds, and flowers of the Cannabis indica or Cannabis sativa plant. It should contain less than 0.3% THC.

Hemp oil is made from the seeds of Cannabis sativa and does not have TCH in it.

CBD DOSING GUIDE – How Much Should I Take? [UPDATED]

UPDATED March 2, 2021 – Ready to reap the benefits of CBD? Awesome. One of the things that is most important to understand how much CBD you should be taking and what a suggested dose is based on. Much of this is dependent on our individual bodies and there is not an official serving size, in this post we cover some dosing guidelines and suggestions to assist you. As you might guess, much of this is a function of our individual weight and metabolism and body chemistry. Dive in and see what is best for you so you can get the most out of your C+L supplements and improve your personal preparation, performance + recovery.

Let’s start by addressing some common misconceptions about CBD. First off: you can’t get “high” using CBD. In order to be legal for sale in the US, CBD can’t contain more than 0.3% concentration of THC, the psychoactive compound responsible for the sensation of “getting high”. In simple terms: virtually no amount of CBD could be consumed to trigger the psychoactive effects commonly associated with THC. Put another way, there’s small amounts of alcohol in toothpaste, but you’re never going to get drunk by swallowing tubes of Colgate. That said, it is important to figure out the right dosage for your needs.

How Much CBD Should I Take?

Dialling in the correct dosage for your body is an important part of getting the most out of your CBD supplements. Once you’ve found the right dosage you’re not only going to get the most benefits from your supplements and feel great, but you’re also going to guard against wasting money by using excess product.

As a baseline, our suggested dosage is 0.25mg CBD multiplied by your body weight in pounds on a daily basis. Therefore, a 120 pound person should take 30mg CBD daily (0.25 x 120 = 30), and a 200 pound person should take 50mg CBD daily (0.25 x 200 = 50). Ideally, split your doses equally between morning and evening. With this formula you can now easily figure out your suggested dose.

That said, there is no ‘official serving size’ or standard dose’ and it varies from person to person. Your ideal dosage will be based on a variety of factors including your weight, metabolism, the type of product you’re using (tincture, softgel, topical), and body type. For the best potential for success, we recommend some experimentation and consistent usage to determine the right dosage for you. It can take 2-3 weeks to determine the proper dosage, but once you witness CBD’s effects on your body you’ll be in a better position to decide how much to take and when to take it, so be patient and take your time.

CBD Dosage

  1. Tinctures – taking the correct amount of tincture can be confusing, so we are going explain it in detail. This is going to be easy using the information from the formula we introduced above. First, you need to be mindful of which strength of tincture that you purchased, 500 or 1000mg. Remember, our examples are based-on only using tinctures, so adjust accordingly if you are also using softgels, oral spray or topicals.
    1. Now, if you purchased a 500mg Tincture, the full bottle will contain ~600 drops worth of tincture and each drop will contain approximately 0.8mg of CBD. Now, if you recall from reading above, we suggest a dose of 0.25mg multiplied by your bodyweight in pounds. For example, if you are 120 pounds you should be taking 30mg CBD per day for best results. Here is our formula 0.25 x 120 = 30mg, and now to convert that into drops, we take 30mg and divide that by the 0.8mg per drop and you get ~35 drops (experiment with between 30-40 drops and see what works best for you). For a 200 pound person, our formula suggests a does of ~60 drops per day (experiment between 60-70 drops per day and see what is optimal).
    2. Let’s run through this same exercise using our 1000mg tincture bottle which also contains ~600 drops of CBD oil. It is important to note that since this product is 2x the concentration that each drop now contains ~1.6mg of CBD. For the same 120 pound person that we used as an example above, you would now take ~15 drops per day (experiment with between 15-25 drops per day to see what is optima)l. For the 200 pound person, they would take ~30 drops per day (experiment with between 25-35 drops per day and see what works best for your body). Check out our PREPARE Tincture for your morning routine or RECOVER Tincture in the evening or 60 minutes before bed.

    Dosage Tips

    In order to figure out the right dosage for you, here are some basic steps to start with:

    1. Start Small – We recommend starting with smaller doses and gradually increasing as needed. Although too much CBD won’t cause any harm, taking more than you need could waste product unnecessarily. If you’re a tincture user, start with 1/2 of our suggested dose for the first week of your PREPARE Tincture in the morning or one dosage of RECOVER Tincture in the evening 60 minutes prior to bedtime.
    2. Take Daily – Everyone’s body is different when it comes to CBD. Many people need to build up the substance in their system in order to start seeing benefits. If you don’t see results right away, keep up your daily doses for four weeks, paying close attention to the changes you sense in your body.

    Once you’ve figured out your ideal CBD dose you’ll be able to feel confident as you start maximizing the positive benefits of your CBD routine and enjoy the effects it has on your personal preparation, performance and recovery.
