An Expert Answers All Your Questions About CBD
From gummies to pills to beauty creams, CBD is everywhere: Americans spent more than $360 million (opens in new tab) on products with this cannabis compound in 2017. And devotees claim it boosts health and has all the bliss-out benefits of weed, minus the paranoia. But how much do you really know about it? We’ll be honest, what it is (and isn’t) and what is does and how it works is complex—and had us more than a little confused before we started working on this project. So we asked an expert, Alex Capano, chief science officer for Ananda Hemp (opens in new tab) , a Kentucky-based health and wellness brand specializing in CBD products—a woman who spends all day every day studying CBD—to breakdown everything we might possibly want to know about the plant derivative. That way, you can feel confident adding it to your medicine cabinet (and nightstand, and handbag) ASAP.
Click a question below to jump to its answer:
What is the difference between CBD and THC?
Though they’re both found in a cannabis plant—meaning either hemp or marijuana—using CBD (full name: cannabidiol) is a far cry from smoking weed. Like THC (or delta-9-tetrahydrocannabinol (opens in new tab) ), CBD is a cannabinoid—a molecule that helps the functioning of our endocannabinoid system, which regulates our mood, sleep cycle, inflammation, immune response, and more. But unlike THC, CBD isn’t intoxicating. “In other words, CBD can’t get you high,” says Alex Capano, chief science officer for Ananda Hemp, a Kentucky-based health and wellness brand specializing in CBD products.
“They both are relatively safe, but CBD is arguably safer for several reasons,” she says. For one, it won’t affect your motor skills or cognition, so you can use CBD and still drive your car or get through a day at the office without causing coworkers to raise an eyebrow. Also, while the THC in a joint, vape pen, or gummy might leave you feeling paranoid, CBD is actually an anxiolytic (meaning it nixes anxiety) and anti-psychotic.
Both THC and CBD come with potential therapeutic benefits (read: can help ease your aches) but they work in different ways. THC decreases the perception of pain, while CBD acts as an anti-inflammatory. Also, CBD alone can treat severe epilepsy. THC, for its part, is better at alleviating chemotherapy-induced anorexia or HIV-associated cachexia, explains Capano, because it increases appetite (hello, munchies). As she puts it: “CBD can help with nausea, but it’s not going to make you eat a bag of Doritos.”
Is CBD legal?
Yes and no. Legality is a complex topic because it depends on where your CBD product comes from, says Capano: “CBD is legal at the federal level only if it’s derived from U.S.-grown hemp that has a license and permit under the Farm Bill; if yours is flown in from overseas or is derived from the marijuana plant, it’s technically not federally legal,” she explains. (A cannabis plant is either hemp or marijuana, depending on how much THC is in it. Hemp has 0.3 percent THC or less by weight (opens in new tab) when harvested, while marijuana has more than 0.3 percent THC by weight and is still federally illegal.)
Making it more complicated: Some states have restricted CBD sales, so even if your product was derived from federally legal hemp, it’s legality where you live does vary by state. There’s a chance, Capano says, that you might run into law enforcement who’s not up-to-date on the bill and arrest you for possessing it—but it’s unlikely.
How do I use CBD?
There are tons of CBD products on the market, from lotions you rub on to capsules you swallow and tinctures you drop under your tongue. All these are made similarly: By extracting CBD, or cannabidiol, from a cannabis plant and then diluting it with a carrier, such as coconut oil, explains Capano. The way you choose to use it is totally a matter of preference and might require some experimentation.
You can’t OD on CBD, but dosage is personal. “More does not necessarily mean better,” warns Capano. “The response dose curve looks like a bell, so you want to hit the top of the bell without going over.” When figuring out your optimal dose, add a bit more every three days or so and see how you respond. If you get to a point where you don’t feel any extra benefit (or feel worse), you’ve gone too far; dial it back a bit the next day.
With a tincture, Capano recommends starting with 10mg of active cannabinoids (this should be on the label). In some products, 10mg is a few drops; in others, it’s a whole milliliter. Put the oil under your tongue and hold it there (no swallowing!) until it absorbs. If taking orally (e.g., popping a pill), you’re going to need more, says Capano, because you lose a bit of the active ingredients to something called first-pass-metabolism by the liver. A pill with 15 or 20 mg of CBD might be comparable to 10 mg of a tincture. “Also, keep in mind that oral ingestion results in a delayed onset,” she says, “so wait an hour or two before adding anymore, especially if there’s THC in there.”
For oils, creams, and other topical treatments—which are a great option for eczema, burns, or other skin conditions—“dosage depends on the concentration of the product, but generally just apply a small amount, as needed,” suggests Capano. Topicals also can help with headaches or migraines if you apply it at onset. And if getting your CBD with a vaporizer, start small. “You need less from a vaporizer and will have a very rapid onset,” she says. For this reason, she recommends trying just 2.5 mg at first.
Whenever you’re starting out with a new product, the best time to try it is right before bed—just in case it makes you drowsy, says Capano. Even if it doesn’t, you’re pretty much guaranteed a good night’s sleep.
Can I vape CBD?
Yes, and it may be your best bet if you’re hoping to achieve quick pain relief. Of all the options for taking CBD, vaping has the most rapid onset; you’ll feel its effects within minutes, says Capano. “Some people use CBD daily for prevention of a migraine, but if they feel one coming on, vaping might be a good way to get an almost-immediate CBD delivery to abort a migraine quickly,” she says.
One caveat: Most vaporizers use either propylene glycol or vegetable glycerin (PG or VG). Those are added ingredients used as carrier oils, and unfortunately we don’t know yet whether they’re safe to vaporize, warns Capano. If immediate pain relief isn’t a priority, another option, like a tincture, cream, or capsule (which take longer to set in), might be the safer way to go.
How much CBD should I use?
Like Capano explained above, the perfect dose varies from person to person. It also depends on a few things—the first being whether you’re using an isolate or full-spectrum product. Isolate products are pure CBD while full-spectrum products contain multiple cannabidinoids and oils, vitamins, and more natural compounds. “With full-spectrum products, you need a lower dose—and that might prevent drug interactions and will be easier on your liver,” says Capano.
Your ideal dosage also varies based on how you’re taking it—you’ll need less from a tincture than a capsule, for instance, because tinctures have a greater bioavailability (meaning more gets into your bloodstream and causes an effect).
But as a general rule? “Start low and go slow,” recommends Capano. “More isn’t always better, it’s like a bell.” Start with 10 mg worth of active ingredient a couple hours before bed. Each day, you can increase the amount slightly and take note of how you feel; dial it back when you don’t feel any extra benefit (or even feel a little worse) from additional milligrams. The sweet spot will likely be between 10 and 40 mg a day.
What are the side effects of CBD?
Unlike smoking a joint, using CBD won’t leave you with a giggling fit or the munchies. It can, however, make you sleepy. “The most common side effect is drowsiness, so don’t take it for the first time and get behind the wheel or head into a big presentation,” advises Capano. Wait to see how your body responds, just in case. In some cases, CBD can exacerbate heartburn or lead to mild allergic reactions, such as hives (though this is likely a reaction to the carrier oil added to the CBD, says Capano). Using CBD can also cause diarrhea or change in appetite or weight, according to a recent German study.
All that being said, if you’re taking CBD for a condition like anxiety or epilepsy, the potential drawbacks are generally milder or less of a nuisance than the side effects you might expect from traditional medical treatments.
The real concern when it comes to side effects, says Capano, is whether or not the CBD in your medicine cabinet is legitimate. You first need to find out if it’s even real CBD, as synthetic can be dangerous. Then look into how the plants are grown, how the product is manufactured, and what quality-assurance tests the brand conducts to ensure safety and the elimination of pesticides, chemicals, microbes, and molds. “It’s an unregulated industry, and there’s a lot of great branding and marketing out there, but unfortunately transparency is rare and not knowing what you’re getting is common,” warns Capano. “Usually that risk just means wasting your money, but it could be harmful, if there are dangerous chemicals in there, for example.” Contact the company with these questions; any reputable brand will be willing to provide customers with all these details.
How long is CBD in my system?
As a general rule, CBD should be out of your system in less than a week after you stop using it. But it varies from person to person, and the longer and more frequently you’ve taken it, the longer it’ll take to get out of your body. Here’s why: It’s lipophilic, meaning it dissolves in fats and compounds in your body over time, says Capano. That’s a good thing when you’re looking to prevent pain or alleviate anxiety, as the compounded levels boost the health benefits, says Capano. But yes, it will make the CBD take longer to leave your system if you decide to stop using it.
Can I take CBD every day?
Not only can you, but for the best effects, in most cases you actually should take CBD on a daily basis. “You can’t overdose on CBD, and it’s lipophilic (or fat soluble), which means it compounds in your body over time, adding to potential health benefits,” says Capano.
Still, “less is more,” she says, because CBD is metabolized through the same pathway in your liver as many common prescription and OTC meds. For that reason, Capano recommends sticking with full-spectrum products (which contain multiple cannabidinoids and oils, vitamins, and more natural compounds) as opposed to isolate products, which are pure CBD. “With full-spectrum products, you need a lower dose—and that might prevent drug interactions,” she explains. (Drug interactions are pretty uncommon, especially at low doses, but can occur with some commonly used ones, such as SSRIs and blood thinners.) Plus, with smaller doses, you’ll avoid stressing out your liver.
“There’s some evidence out there that CBD can adversely affect a damaged liver, and there’s other evidence that shows it can be helpful—it seems to depend on the underlying cause of liver damage,” Capano adds. If you already have liver issues, talk with your doc, keep a close eye on your dosage, and be sure to monitor hepatic enzymes every three months.
What drugs should I not combine with CBD?
The bad news: Your body metabolizes CBD through a pathway in your liver known as CYP 450, where enzymes break up potentially harmful compounds—and it’s the same pathway in your liver that metabolizes most common prescriptions and over-the-counter medicines, says Capano.
The good news: You likely aren’t taking a high enough dose of CBD that it will cause an adverse reaction with any other medications you might be taking. To lower your risk even more, make sure the CBD you’re using is a full-spectrum product rather than an isolate, so you can get the same benefits at a lower dose. Also, opt for a product that’s not oral, as capsules involve a first pass through the liver that tinctures and other products don’t.
“Most people using full-spectrum CBD are taking no more than 40 to 60 mg a day, and we haven’t demonstrated drug interactions at those levels,” says Capano; you’d likely need to use upwards of 20 mg per kilogram of your bodyweight before seeing interactions. But talk with your doctor before combining CBD with any drugs you’re already on, especially if you take blood thinners or antidepressants, advises Capano.
How long does CBD take to work?
How fast your CBD takes effect totally depends on what form you’re using. Need to kick an acute ache, like a migraine, ASAP? Try vaping, suggests Capano. Vaporizing CBD has the fastest delivery—you should feel the effects set in within mere minutes.
If your needs are not quite so urgent, you might opt for a tincture; you’ll still feel the effects soon—usually within 20 minutes to an hour—since the liquid quickly absorbs into your bloodstream after you drop it under your tongue. This usage allows the CBD to bypass a first pass through your liver that capsules require before you feel their effects.
If you use CBD daily for preventative reasons and don’t need quick relief, an oral product might be for you. They take the longest to onset (read: at least an hour or two), but, says Capano, “they’re a good option for people who don’t like the taste of tinctures and want the convenience of capsules.”
Will CBD help my skin?
You bet. CBD can help clear up and calm down your skin in a few ways. For one, it works by relieving stress, which happens whether you take CBD orally or topically, says Capano: “We know that mood, especially stress, can influence skin irritation—so this is kind of a one-two punch.”
It also helps cell turnover, which can improve acne prone skin and brighten your complexion. Plus, because of its potent inflammatory properties, CBD can even lessen overactive sebum production and breakouts, and can reduce the frequency and severity of eczema and psoriasis flares.
You can even use it in place of hand sanitizer in a pinch. CBD is naturally antimicrobial and can help kill some nasty germs. Ananda Hemp’s oil has shown 99.9 percent antimicrobial effectiveness against staph and MRSA in tests. How well a CBD product kills germs does depend on how concentrated it is, so check with the manufacturer before relying on it. Also, keep in mind that CBD has only been shown to protect against gram positive bacteria, such as staph and strep—not against gram negative bacteria, like E. coli, notes Capano. So you shouldn’t rely on it for keeping you totally bug-free. “It’s better than nothing, but CBD isn’t a substitute for hand soap,” she says.
Can CBD lower my anxiety?
Nixing your nerves is one of the top reasons people are turning to CBD products (along with lessening pain and help sleeping). There’s still research to be done on how exactly it works to calm anxiety, but one thing we do know is that it blocks an enzyme called FAAH, which works to lower a fatty-acid neurotransmitter called anandamide, explains Capano.
For the non-scientists among us, by blocking FAAH, CBD can help increase your level of anandamide. And that’s a big deal when you’re looking for a mood boost. This neurotransmitter (the same one that leads to the elusive runner’s high) is named after the Sanskrit word for joy, bliss, or happiness. Basically, says Capano, “CBD makes our natural bliss molecule work better for us.”
Bonus: If CBD is easing your aches or increasing your ZZZs, that might in turn leave you feeling even more relaxed.
Does CBD relieve pain?
Get ready to kiss that nagging knee or back pain goodbye. Along with improvements in sleep and mood, chronic aches are the main reason people are turning to CBD. That’s because cannabidiol is an anti-inflammatory agent. In other words, it helps reduce the inflammation causing the pain, rather than reducing your perception of pain. “Percocet will just make you feel like you don’t have pain while CBD will get at the root cause,” explains Capano. CBD also helps nix pain because it’s an antioxidant itself, increases our own natural antioxidants, and works on serotonin receptors.
While all that combines to mean CBD has magical pain-slashing properties for certain aches, it’s not ideal for every kind. It’s a great, effective therapeutic option for chronic pain and pain prevention (e.g. frequent headaches, ongoing back pain that’s lasted more than a week), says Capano. “But if you have an acute injury, like a broken bone, CBD is not going to be a substitute for morphine in the hospital; those really strong narcotic painkillers have their place.”
That said, if you’re dealing with chronic pain and are already on medication for it, talk with your doctor about combining those traditional meds with CBD. More than 50 percent of long-term opioid users who added CBD to their treatment were able to reduce their opioid use and 90 percent of them had better quality of life within two months, according to research Capano recently conducted, which is pending publication. “We know that CBD is effective with pain and it’s safe to use with opioids—plus, it can help with withdrawal symptoms as you lower opioid use,” she says. “There’s pretty good data that CBD can be a treatment for substance abuse disorders. We should be motivated to use something that’s safer and doesn’t have the risk of dependency or overdose.”
Where can I buy CBD?
If you’re in a big city, you’ve likely seen CBD all over—from chic pop-up shops to your corner bodega. If you’re in a small town, you can probably find it in a brick-and-mortar shop too, as lots of small, independent pharmacies are carrying CBD products now. But if you do have trouble tracking it down in person, you can easily order online and have it shipped to any state (since U.S.-grown CBD is legal nationwide per the Farm Bill). But keep in mind: “There are so many online retailers, you have to do your homework,” says Capano.
To make sure you’re getting a legit product, research the brand before purchasing from it and find out where it sources its CBD. If you can find a company that’s vertically integrated—meaning they have control over the growth of their plants—that’s ideal, notes Capano. (It’s not essential, though, and might be difficult to find a vertically integrated brand, as only a handful of companies in the U.S. are.)
You should also ask if the brand does third-party testing, what level of actives are in the product, whether it contains any microbial contaminants or pesticides. Not only should any reputable company make this info readily available, but they also should include a batch number with every product, so you can see a lab analysis. Don’t be afraid to push for all these details, says Capano: “The more we demand transparency that as consumers, the better the industry will get.”

CBD is available in a number of different formulations including creams, tablets, oils, and gummies. These can vary in terms of their ingredients as well as dosages, and there is not a great deal of research available on what dose might be beneficial or safe to treat certain conditions.
Cannabidiol (CBD) is the second most abundant cannabinoid found in marijuana. Unlike tetrahydrocannabinol (THC), CBD does not have psychoactive effects. Interest in the use of CBD for health purposes has grown tremendously in the last few years.
CBD is believed to have a range of positive physical and mental health effects. Because of this, it has become increasingly popular as a way to alleviate everything from anxiety to sleep disorders.
In order to determine if CBD is right for you, it is important to consider its potential benefits, side effects, and available research on safe dosages.
CBD is just one of hundreds of different compounds found in the cannabis plant. While cannabis has been used in holistic medicine for many years, only recently have researchers begun to explore some of the medicinal purposes for CBD and other cannabinoids.
While further research is still needed, there is some evidence that CBD may have some beneficial mental health effects. These include:
- Alleviating depression: Some research also indicates that CBD may be useful as a treatment for depression. Studies suggest that the cannabinoid might have an influence on how the brain responds to serotonin, a neurotransmitter that plays a key role in mood. People with depression sometimes have a low level of serotonin, so CBD may help the brain use available serotonin more effectively.
- Improving sleep: While the reasons are not entirely understood and require further research, CBD also appears to have potential as a treatment for sleep problems. For example, one study found that people who took CBD also reported improvements in the quality of their sleep.
- Reducing anxiety: Anxiety is one of the most common types of mental health conditions, affecting almost 20% of American adults each year. Research suggests that CBD may help alleviate acute symptoms of a number of anxiety-related conditions including generalized anxiety disorder, obsessive-compulsive disorder, and social anxiety disorder.
In addition to the mental health benefits, CBD may also have therapeutic benefits for a range of other conditions. The World Health Organization suggests that CBD may have beneficial effects in the treatment of:
- Alzheimer’s disease
- Cardiovascular disease
- Multiple sclerosis
It is important to remember that these benefits have not yet been conclusively proven. More research is needed to determine the role that CBD might play in the treatment of different disorders and health conditions.
There have been a number of studies that suggest that CBD may have a number of different physical and mental health uses. However, more research is still needed to better understand the substance’s potential applications and possible long-term side effects.
A 2019 comprehensive review published in The Lancet Psychiatry looked at previously published studies. The review ultimately concluded that there was little evidence to support the use of CBD for mental health purposes and suggested that more research is needed in order to substantiate its use to treat symptoms of conditions such as anxiety, depression, and insomnia.
It is important to remember that this doesn’t mean that CBD isn’t effective. Many of the studies that were included in the review were small, had few participants, and were not randomized controlled trials.
This suggests that more research involving more participants and well-designed studies is needed in order to better understand if, how, and why CBD works.
While its effectiveness is still up for debate, one 2017 review found that it was a relatively safe option. While it is important to remember that there is still a great deal we don’t yet know about CBD and its effects, it is something that you might opt to try to see if you experience any benefits.
How Much Should You Take?
The dosages used in research studies vary and there is no consensus on how much should be used for specific conditions. If you do decide to try CBD, it is also important to note that there is no universally agreed upon dose. Research also suggests that people may respond differently to various dosages, so the amount that is right for your needs might vary.
Some dosages that have been used in research studies for different conditions include:
- Anxiety: 300 to 600 mg
- Bowel disease: 10 mg per day
- Cancer-related pain: 50 to 600 mg per day
- Parkinson’s disease: 75 to 300 mg per day
- Poor sleep: 25 mg per day
- Psychosis: 600 mg per day
One 2020 review of studies found that participants showed improvements in anxiety levels after single doses of CBD ranging from 300 to 600 mg. Such results indicate that the CBD may hold promise as a treatment to alleviate symptoms of acute anxiety.
It is important to remember that you should always talk to your doctor before using CBD if you have symptoms of a serious mental or physical health condition. CBD could potentially worsen symptoms or interact with other medications you are taking.
Looking at the dosage information for the CBD product that has been FDA approved can also be helpful. For Epidiolex, an FDA-approved cannabis-derived medication used to treat seizures in people with certain types of epilepsy, the starting dosage is 5 milligrams per kilogram of body weight. This dose can later be increased to 5 mg per kilogram of body weight twice a day.
Other CBD products are not FDA regulated and do not have officially recommended dosages. This can make it difficult to determine how much you might need, but there are some things you can consider that might help.
- Assess your sensitivity to CBD: Your individual ability to tolerate CBD can also play a role in determining how much you need. If you are very sensitive to the effects of CBD, you should take a small dose. Some people may find that they are not as affected by the substance, so they may need to take a larger dose to notice any beneficial effects.
- Consider individual factors: When you are trying to decide how much CBD to take, there are a number of factors you should consider. These include the formulation and concentration of the capsule, oil drops, or gummies you are taking, the symptoms you are treating, and your age, sex, weight, and overall health. Generally, people with heavier bodies need to take a little more to achieve the same effects. Men may need a larger dose, while older people may need less.
- Consider the symptoms you’re treating: The symptoms you are trying to alleviate can also play a role in the CBD dosage you need to take to see results. In one study, participants who took 25mg of CBD each day had improved sleep quality, although the results were not consistent. However, you might find that you need a lower or higher dose if you are treating another type of condition.
- Try a dosage calculator: Researchers note that while the variety of dosing strategies and formulations make it difficult to determine efficacy, there are a number of online “dose-calculators” available online (such as mydosage.com) that are designed to help people choose the correct dose. The accuracy of such calculators is difficult to assess, but it may be a good place to start.
Before you try CBD, discuss your plan with your doctor. They may be able to recommend a dose and help you better understand any potential risks, complications, side effects, or interactions you might experience.
Start With a Low Dose
Unless your doctor recommends a specific dose, start by taking 10 to 20 mg a day. Take this for a week to ensure that it is well-tolerated and that you don’t experience any unwanted effects or an allergic reaction.
If this dose does not have the desired effect, try increasing in increments of 5mg each week until the desired amount is reached.
In studies, amounts vary from as low as 20 milligrams per day to up to 1,500 milligrams (mg) per day. The World Health Organization reports that dosages in clinical research studies typically range between 100 and 800 milligrams per day.
Is It Possible to Take Too Much?
So what is the maximum amount of CBD you should take? Researchers have found that 600 mg per day appears to be safe, but one study suggested that doses of up to 1,500 mg a day are safe and tolerated well.
However, it’s important to remember that research is still in its infancy and experts do not yet fully understand the potential long-term impacts of CBD usage. For that reason, you should always discuss your CBD use with your doctor.
Starting at a lower dose and working your way up to the amount you need may be the best ways to avoid taking too much.
How to Take CBD
The amount of CBD found in a product may depend on different factors, including the formulation and method of administration. CBD products are available in a number of different forms including oils, capsules, tablets, nasal sprays, and gummies.
One of the most popular ways to take CBD is as an oil. Such products are made by combining CBD with some type of carrier oil, such as coconut oil. Some more recently developed products include dietary supplements, foods, beverages, lotions, salves, and cosmetics.
The type of CBD product you choose may depend on what you are trying to treat. If you are looking for general mood improvements, a dietary supplement might be a good option.
If you are targeting specific symptoms of a condition, taking an oil, capsule, or gummy might be a better way to obtain a higher, more concentrated dose.
Topical applications may produce localized effects, but they are unlike to have any mental health benefits.
What Kind Should You Take?
It’s also important to remember that many products don’t contain just CBD on its own. There are three types of CBD available:
- Isolate contains CBD and only CBD.
- Broad-spectrum contains CBD and other cannabinoids, but not THC.
- Full-spectrum contains CBD, THC, and other cannabinoids.
It may be helpful to take a broad-spectrum product since research suggests that CBD’s effects may be most beneficial when taken in conjunction with other cannabinoids, a phenomenon known as the entourage effect. CBD may also help mitigate some of the effects of THC.
While CBD is generally well-tolerated, this does not mean that you won’t experience any side effects.
Some of the most common side effects that people experience when taking CBD include:
- Appetite changes
- Stomach upset
- Weight changes
Some recent research has generated concerns over the safety and potential long term effects of CBD. One study involved giving mice an equivalent of the maximum dose of the CBD medication Epidiolex, which is used to treat certain forms of epilepsy. The results indicated an increased risk for liver damage as well as concerns over its interaction with other medications.
It is also important to remember that CBD products are not regulated by the U.S. Food and Drug Administration (FDA). Some manufacturers make unproven claims about the uses and efficacy of their products. There is also concern about the quality and safety of the products themselves.
One report by the Centers for Disease Control and Prevention (CDC) indicated that a number of people experienced negative unwanted side effects due to CBD products that contained synthetic CBD, although the products were not labeled as containing such ingredients.
Mislabeling appears to be a fairly common problem with CBD products. In one study, 70% of the CBD products that were sold online contained significantly more of the psychoactive ingredient THC than the label indicated.
Federal law prohibits the sale of products that contain more than 0.3% THC. States laws also vary, so you should always check with your state before buying CBD products online.
A Word From Verywell
If you do decide to take CBD to alleviate an acute or chronic condition, remember that the amount that you take will depend on a variety of factors. Finding the right dosage often takes some experimentation and adjustments. Starting with a low dose and then gradually increasing the amount you take until you achieve the desired effects is the best approach.
