Cannabis contains over 113 different chemical compounds known as cannabinoids. Cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC) are two types of chemical compounds derived from cannabis. In recent years, interest has grown in the potential health effects and benefits of cannabis. Much of this interest has centered on these two cannabinoids.
This interest will likely grow as cannabis and marijuana products become legal in more states. A number of different products have emerged that contain CBD, THC, or both that are designed to alleviate ailments such as stress, anxiety, and insomnia. To understand these products’ side effects and potential benefits, it is important to first understand the differences between CBD and THC.
What Is CBD?
Cannabidiol, usually referred to as CBD, is the second most prevalent chemical compound found in cannabis. First discovered during the 1940s, CBD has recently become more popular as a natural treatment for a range of conditions. It can be derived from hemp or from marijuana. Hemp-derived CBD still contains trace amounts of THC, while marijuana-derived CBD may contain more.
What Is THC?
Delta-9-tetrahydrocannabinol, or THC, is the main psychoactive ingredient in cannabis. According to the National Institute on Drug Abuse (NIDA), THC activates the brain’s reward system by signaling the release of the brain chemical dopamine.
Dopamine is a neurotransmitter that plays an important role in mood and pleasure. By triggering a higher-than-normal release of dopamine, THC causes people to experience feelings of euphoria. THC is often administered by smoking marijuana, but it can also be found as an ingredient in capsules, edibles, and oils.
CBD vs. THC: Key Differences
THC and CBD have an effect on the endocannabinoid system, a system that plays an important role in maintaining homeostasis. Researchers are still working to understand the ins and outs of this complex system, but they do know that it is associated with processes including memory, appetite, sleep, mood, and fertility.
While THC and CBD share similarities, there are some key differences between the two compounds.
Psychoactive (produces a high)
Sourced from marijuana
Non-psychoactive (does not produce a high)
Typically sourced from hemp
CBD vs. THC: Psychoactive Properties
CBD and THC affect different receptors in the brain. Because of this, CBD typically does not have psychoactive effects—in other words, it won’t cause you to get high.
THC, on the other hand, does have psychoactive effects. It is the compound that produces the high that people associate with marijuana.
CBD vs. THC: Chemical Structure
Both CBD and THC have a chemical structure that is similar to the body’s natural endocannabinoids. Endocannabinoids are neurotransmitters that act in the brain.
Neurotransmitters are chemical messengers that relay signals between nerve cells in the body. They play an important role in a wide range of functions including sleep, pain, appetite, mood, and the immune system.
CBD and THC have the same molecular structure, but there are differences in how these molecules are arranged that are responsible for the differing effects they have. By mimicking endocannabinoids, they bind with receptors and cause different effects in the body.
CBD vs. THC: Sources
While CBD can come from either hemp or marijuana, it is often derived from hemp in order to avoid the addition of larger amounts of THC. THC, on the other hand, is derived from marijuana.
CBD that comes from marijuana may contain more THC, which may not be ideal for people who are trying to avoid THC. Some CBD products that are produced from cannabis, for example, may contain more THC than the label suggests.
CBD vs. THC: Potential Benefits
While research on the potential health benefits of THC, CBD, and other cannabinoids is still in the early stages, there is evidence that these substances may be helpful for conditions including:
- Symptoms of HIV/AIDS
- Opioid dependence
- Irritable bowel syndrome (IBS)
- Inflammatory bowel syndrome (IBD)
- Multiple sclerosis
- Sleep difficulties
- Movement disorders
While CBD and THC often have similar effects and are often used to treat many of the same ailments, there are some differences.
CBD is often used to alleviate symptoms associated with:
THC, which may be administered as medical marijuana, may be used to alleviate symptoms of a number of conditions. It may be helpful for conditions such as:
- Nausea; it may help alleviate nausea caused by cancer treatment
- Pain associated with conditions such as arthritis, fibromyalgia, and migraine headaches
- Poor appetite; including appetite problems caused by cancer treatment
CBD vs. THC for Pain Relief
Both CBD and THC can both be beneficial for pain relief. Because THC has psychoactive effects, it may produce more immediate pain relief. However, CBD can help reduce inflammation, which is useful for long-term effectiveness. Some evidence suggests that taking both CBD and THC may provide the greatest pain relief. In one study, people who took a combination of CBD and THC experienced greater pain relief than those who took THC alone.
While cannabis itself has not been FDA approved to treat any condition, there are a few drugs approved by the U.S. Food and Drug Administration (FDA) that contain CBD or THC.
- Epidiolex contains CBD and has been approved to treat seizures associated with two severe types of epilepsy—Dravet syndrome and Lennox-Gastaut syndrome
- Marinol and Syndros are drugs that contain dronabinol, a synthetic THC. These drugs are used to treat nausea and vomiting caused by chemotherapy during cancer treatment.
- Cesamet contains nabilone, a synthetic substance that is similar to THC. This drug is used to treat weight loss and appetite problems associated with chemotherapy and HIV/AIDS.
CBD vs. THC: Side Effects
Some research suggests that CBD and THC are generally safe and result in few side effects.
However, while these substances appear safe, that does not necessarily mean that you won’t experience some unwanted effects. Some adverse effects that have been reported include:
- Changes in mood and appetite
- Feelings of anxiety or other mood changes
- Nausea and dizziness
THC use may also result in unpleasant side effects such as increased heart rate, dry mouth, and memory loss.
Marijuana itself can have a number of short-term and long-term adverse effects, including impaired short-term memory, altered judgment, and impaired coordination. Research also suggests that marijuana can alter brain development and may lead to cognitive impairment.
NIDA also notes that THC alters how the hippocampus and orbitofrontal cortex function. These areas of the brain are important in the formation of new memories and the ability to shift attention from one thing to the next. This not only affects a person’s ability to learn and form new memories, but it also makes it difficult for people to perform difficult tasks.
Legality of CBD and THC
When choosing CBD or THC products, it is also important to consider their legality. Both marijuana and THC are included in the U.S. Controlled Substances Act, which means that they are not legal under federal law.
As of July 2020, 33 states and Washington, D.C. have enacted policies allowing medical marijuana and products containing THC to be prescribed by a doctor. Some states also allow recreational use of marijuana and THC-containing products.
Although CBD in certain forms is legal in most states, the specifics of the legality of any THC or CBD product can vary from one state to the next. Several states have also approved the use of marijuana and THC for recreational purposes.
Because the laws regarding the use of cannabis and cannabis products are rapidly changing, you should always check your state’s laws before using products containing CBD or THC.
How to Take CBD and THC
Both THC and CBD can be consumed in a number of different forms. THC may be consumed as marijuana by smoking, but a number of other cannabis products are also available including:
- Vape products
- Edibles including gummies and chocolates
- Beverages containing marijuana oil
Like THC, CBD can also be consumed in a number of different forms. CBD oils can be formulated for vaping, although there have been recent concerns about the health dangers posed by vaping.
It can also be added to lotions and salves to apply to skin. It is important to note that the effects of these topical products will be localized since they are not being ingested.
CBD can also be taken orally as a tincture, oil, capsule, or spray. Edible CBD products are also popular and include gummies, candies, and beverages.
When choosing CBD products, it is also important to consider its formulation. Isolate products contain only CBD. Broad-spectrum products contain other cannabinoids with the exception of THC, while full-spectrum CBD products contain CBD, THC, and other cannabinoids.
Which One Should You Take?
The product you choose may depend on the effects you are trying to achieve. If you are trying to reduce stress or sleep better, for example, CBD may provide benefits without the negative side effects associated with THC. THC might be a better choice for symptoms or conditions for which the substance has demonstrated benefits, such as tremors or poor appetite.
The Entourage Effect
Some research suggests that the potential therapeutic effects of THC and CBD tend to be greater when the two cannabinoids are taken together at the same time. This phenomenon is known as the entourage effect.
Taking CBD along with THC has also been shown to help reduce some of the unwanted effects that THC may have. For example, one study suggests that CBD may potentially reduce some of the negative cognitive effects of regular cannabis use.
For example, people who use cannabis, particularly when it has high THC levels, may have a greater risk of experiencing psychiatric symptoms such as paranoia, anxiety, and psychosis. Studies have found, however, that CBD may help mitigate these effects.
One study found that CBD helped block some of the potential psychiatric effects of THC. The authors of the study suggest that such findings have important implications for the use of cannabis products. People who are prone to unwanted side effects, for example, may be able to still gain the potential health benefits by sticking to products that are low in THC and higher in CBD content.
It is also important to remember that CBD and THC work in a number of different areas of the brain, and researchers do not yet fully understand the effects that these cannabinoids have, either alone or in conjunction with one another.
Some evidence suggests that the combined effects of CBD and THC may be dependent on dose. A 2019 study, for example, found that low doses of CBD actually played a role in amplifying the psychoactive effects of THC, while high doses of CBD reduced THC’s effects.
Drug Testing CBD or THC
Because THC is the main psychoactive substance in marijuana, it can be detected on most standard drug tests. CBD may be detectable as well, but many drug tests are not designed to look for cannabidiol.
However, many CBD products do contain trace amounts of THC. While these amounts are small, they may still be detectable if you are consuming large quantities of CBD or if the products you are using contain more THC than the packaging label claims.
Research has found, for example, that as many as 70% of CBD products are mislabeled and contain significantly more THC than labels suggest. Because of the lack of regulation of these products, it is difficult to know exactly how much THC you are actually getting.
There is no way to tell between THC and CBD based on appearance, smell, taste, or texture. Purchasing products from reputable manufacturers and retailers may help ensure that you are getting the type of product you want.
Both THC and CBD are stored in body fat, which means that both can potentially be detected on drug tests for some time after you have stopped using them.
Before You Take CBD or THC
THC and CBD may also have an effect on some health conditions and can interact with certain medications, so you should always use caution before taking these products. These substances might impact how medications are metabolized by your body. They can also heighten feelings of anxiety in some cases.
Before choosing a THC or CBD product, it is important to check your state laws to ensure that these products are legal where you live. Federal law mandates that hemp-derived CBD products should contain less than 0.3% THC, but even those trace amounts are still illegal in some states.
A Word From Verywell
Both THC and CBD may have a number of benefits, but you should always talk to your doctor first before you try any products containing these cannabinoids. Both CBD and THC hold promise for alleviating symptoms and even treating some medical and mental health conditions, but research in this area is still relatively new and further investigation is needed.

CBD vs. THC: What’s the Difference?
You’re probably hearing a lot about cannabis and marijuana products as they become legal in more and more states. Two natural compounds are getting the most attention: CBD and THC.
Cannabis is a plant that makes a thick substance full of compounds called cannabinoids. There are more than 100 of these chemicals in cannabis. They cause drug-like reactions in your body.
CBD (cannabidiol) and THC (tetrahydrocannabinol) are the most common cannabinoids found in cannabis products.
THC and CBD are in both marijuana and hemp. Marijuana contains much more THC than hemp, while hemp has a lot of CBD.
CBD and THC have the same chemical formula — 21 carbon atoms, 30 hydrogen atoms, and two oxygen atoms. The difference lies in the way the atoms are arranged. That gives CBD and THC different chemical properties, and they affect your body differently.
Both CBD and THC work with receptors that release neurotransmitters in your brain. They can affect things like pain, mood, sleep, and memory.
How CBD and THC Affect the Body
THC is the main psychoactive compound in marijuana. It’s what makes people feel “high.”
We have two types of cannabinoid receptors in our bodies. THC binds with receptors — mostly in the brain — that control pain, mood, and other feelings. That’s why THC can make you feel euphoric and give you that so-called high.
CBD doesn’t cause that high. Instead, it’s thought to work with other elements in the body linked to feelings of well-being.
People take CBD products to help with everything from arthritis and Crohn’s disease to diabetes and multiple sclerosis. Some say it helps with anxiety, insomnia, and chronic pain. So far, there’s little evidence that CBD helps with any of these.
The FDA has approved one CBD-based drug. Epidiolex is a treatment for several severe forms of rare childhood epilepsy.
CBD is a hot topic for researchers. The National Institutes of Health clinical trials database shows more than 160 trials involving CBD that are either active or recruiting.
Some states authorize the use of THC as part of medical marijuana, THC may help ease things like:
- Problems with concentration
- Memory loss
Side effects from CBD can include:
- Upset stomach
CBD can also change the way some medicines work. Talk with your doctor about it.
Laws are changing all the time on cannabis. Many states allow medical marijuana, containing THC, for several uses, but it is still illegal under federal law. Some states have made recreational marijuana with THC legal for personal use. But it’s also illegal under U.S. law.
As part of the Farm Bill in December 2018, Congress legalized hemp. But there are still rules about where and how you can sell products that contain CBD. You can’t sell some across state lines, for example. All CBD products are illegal if they’re sold with the promise of medical benefits.
Check your state’s laws before buying products with CBD or THC.

Cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC) are both substances that are extracted from various species of plants in the Cannabis genus. However, they are two distinct compounds with different effects. They are not the same thing.
In 2018, the Farm Bill was signed into law. It removed hemp (a variety of the Cannabis sativa plant) and derivatives of cannabis with low levels of THC (0.3% or less) from the definition of marijuana in the Controlled Substances Act.

There are many misconceptions and much misinformation circulating. When reading about CBD and THC, it’s essential to know what various terms mean. Without knowing what different terms mean, it’s easy to get confused.
Delta-9-tetrahydrocannabinol (THC) is the naturally occurring substance in the cannabis plant that produces the “high” or the effects of marijuana.
Cannabidiol (CBD) is a cannabinoid compound found in the cannabis plant. It does not produce a high because it does not have THC in it. It can produce relaxation or sleepiness. It has antioxidant (neutralizes destructive oxygen free radicals in cells) and anti-inflammatory properties.
|CBD vs. THC Chart|
|Source||Aerial parts of the cannabis plant (stalk, leaves, flower), can be derived from low-THC hemp.||Leaves and the flowering part of the cannabis plant|
|Psychoactive Effects||There is no high, but it can promote relaxation and reduce anxiety and depression.||Euphoria, heightened senses, changes in time perception|
|Medicinal Effects||Anti-seizure effect, pain relief, reduces inflammation||Tachycardia (increased heart rate), increased appetite|
|Legality||Technically legal federally, state legality depends on the state||Not legal federally, state legality varies by state|
|Detected on Drug Test||Cannabidiol is not detected, but if the preparation has any THC in it, that could be detected.||Yes|
Hemp vs. Marijuana
Hemp and marijuana are technically the same kind of plant—cannabis. However, hemp plants have no more than 0.3% (by dry weight) of THC. Marijuana has 5%–20% THC. Hemp cannot get you high.
According to the World Health Organization (WHO), a psychoactive substance is a substance that, when consumed, impacts mental processes (thinking, mood, perception, consciousness). This definition doesn’t necessarily only refer to recreational drugs—it can also include substances like nicotine or caffeine.
Synthetic vs. Natural
Synthetic CBD is made in a lab with chemical or biological ingredients. Natural CBD is taken from cannabis plants.
Both CBD and THC are cannabinoids from the plant Cannabis sativa. They both have the same chemical makeup: 21 carbon atoms, 30 hydrogen atoms, and two oxygen atoms. However, the arrangement of the atoms differs. The body reacts to them as two different substances.
Effects of CBD vs. THC
The effects of CBD and THC on the body are quite different. Knowing the difference between the two can help you know what to expect if you use these substances.
CBD can have many different medicinal effects, and has multiple mechanisms of action—at least 20 have been identified thus far. It has been found to:
- Mediate antiepileptic effects: It binds to a protein called GPR55 that triggers seizures.
- Mediate pain signaling and inflammation: It acts on receptors in these pathways.
- Relieve neuropathic pain and have an antidepressant effect: It acts like selective serotonin receptor inhibitors (SSRIs), which are medications used to treat depression.
- Decrease psychotic symptoms: This effect may be seen in people with schizophrenia (a mental health condition in which there is an altered perception of reality). It may have an additive effect when used with traditional antipsychotic drugs (when used together, there may be better control of hallucinations and delusions).
- Reduce anxiety symptoms
More studies are needed to evaluate CBD’s mechanisms of action and whether its effects are clinically significant consistently.
Drugs with cannabinoids (CBD and/or THC) can be helpful in treating nausea and vomiting in people undergoing cancer chemotherapy, and weight loss and loss of appetite associated with human immunodeficiency virus (HIV) and AIDS. They may also help with chronic pain and symptoms of multiple sclerosis.
CBD is not used as a recreational drug like marijuana is. While it can help you feel more relaxed or less anxious, it doesn’t make you “high.”
Recreationally, effects of THC can include:
- Alteration of the senses
- Alteration of your sense of time
- Mood changes
- Trouble with body movement
- Impaired memory
- Trouble thinking or problem-solving
- Hallucinations or delusions (losing touch with reality): Risk is highest when regularly using high-potency marijuana.
Industrial and Cosmetic Uses of CBD
CBD can offer relief for various conditions, including skin and cosmetic disorders such as eczema (an inflammatory skin condition) and psoriasis (an autoimmune skin condition).
The human endocannabinoid system (ECS) helps with bodily homeostasis (maintaining a steady state). It helps to maintain skin homeostasis, and when it is dysregulated (out of balance), hyper/hypopigmentation (skin patches with increased or decreased color), atopic dermatitis, hair growth or loss, itch, and acne can occur.
Because CBD has anti-inflammatory properties, it can help with disorders that cause inflammation and/or itching, like atopic dermatitis. More research needs to be done, but CBD may also help with acne because it may inhibit bacterial growth and the production of more oil-making skin cells.
Although CBD shows promise for cosmetic uses for the skin and hair, more studies need to be done to evaluate its effectiveness.
Although CBD is not a psychoactive substance, it isn’t legal in every state. In order for CBD to be legal in your state, it needs to be legal at both the federal and state levels.
While the Farm Bill legalized the production of any part of the cannabis plant with a THC concentration of 0.3% or lower, states have the final say.
CBD Legal States
Even though CBD cannot get you “high,” it is not legal in every state. While some states have no restrictions on CBD, others have legalized CBD only for medical purposes. Some regulate it depending on whether it was derived from hemp or marijuana. Others have not legalized it at all.
Laws continuously change. Before you purchase or use any CBD product, even without THC, it’s best to check your state laws. One resource to do so is the National Conference of State Legislatures, on their State Medical Cannabis Laws page.
THC Legal States
Laws regarding THC are actively changing. It is important to check the most current laws in each state. Some state laws vary in the level of THC that is legal, or for what purpose THC can be consumed.
The National Conference of State Legislatures State Medical Cannabis Laws page may be helpful, as is the state information at the National Organization for the Reform of Marijuana Laws (NORML) website.
On a Drug Test
Drug tests specifically look for THC and its breakdown products. CBD should not produce a positive test.
While CBD shouldn’t show up on a drug test, some CBD products do have THC, so it may cause a positive THC result on a drug test. Many CBD products are not regulated, so you don’t know what exactly is in them or how much THC they contain.
The bottom line is that if CBD or THC is illegal in your state or is forbidden in your workplace, it’s best to not use them or limit your usage.
As with any ingested substance, there are potential side effects to both CBD and THC. Additional side effects of CBD than the ones already listed can include:
- Changes in alertness, usually drowsiness
- Gastrointestinal issues like diarrhea or lack of appetite
- Mood changes like irritability or agitation
Side effects of THC (in addition to the recreational ones) may include:
- Changes in blood pressure and heart rate
- Red eyes
- Increased risk of mood disorders
- Lung irritation with chronic usage
Types of CBD and THC
There are different types of CBD and THC. Knowing the differences can help you make a choice about which is best for you.
The types of CBD include:
- Whole plant CBD: Uses all of the hemp compounds but is usually too thick for general use
- Full spectrum CBD: Contains none of the waxes or oils from whole plant CBD, but has traces of THC
- Broad spectrum CBD: Contains no THC but has other cannabinoids, terpenes, and flavonoids
- Pure CBD (isolate): Contains only CBD, no THC, and no other compounds
The types of THC include:
- THC-a: This is the most common type of THC in cannabis, and is the precursor to the other kinds. It does not produce psychoactive effects.
- Delta 9 THC: This is responsible for producing the typical psychoactive effects of marijuana, and also helps relieve bodily tension and increases appetite.
- Delta 8 THC: This makes up less than 1% of the cannabis plant and is supposed to be half as psychoactive as delta 9.
- THCP (tetrahydrocannabiphorol): This is said to have approximately 33% more potency and strength than delta 9 but medicinal benefits are unknown.
- THCV (tetrahydrocannabivarin): This is not as effective in binding to receptors. In large doses it can be psychoactive, but not in low doses.
While CBD and THC are from the same plant, the cannabis plant, they are very different. Both can increase relaxation and sleepiness, improve mood, and relieve pain, but CBD does not have the same psychoactive properties that THC does.
There are different kinds of CBD. It’s good to know what kind you are using because some may have traces of THC in them. Knowing more about CBD and THC can help you make informed decisions about what you choose to consume.
A Word From Verywell
While CBD and THC may be legal in some states, in other states there are restrictions on both. Before ordering or using these substances, it’s always a good idea to check the laws in your state about both CBD and THC.
Frequently Asked Questions
Smoking a product containing THC (like a marijuana “joint”) or vaping CBD oil can start relieving pain in a few minutes. Creams and edibles can take a bit longer, even up to a few hours for edibles, since they have to go through the digestive tract.
The effects of delta-8 THC are more potent than CBD. Whereas CBD does not get you high, delta-8 does. It is similar to delta-9, which produces the high and side effects of marijuana than it is to CBD.
Everyone’s experience with THC or CBD is different. While THC in low doses tends to reduce anxiety, THC has been shown to increase anxiety in high doses. CBD has been found to decrease anxiety at multiple doses.
It’s good to let your healthcare provider know if you use CBD or THC. They can interact with certain medications and may cause physical health issues, so your healthcare provider should know if you use these substances.
