As the legal use of hemp and other cannabis products grows in the United States, consumers are becoming more curious about their options. This includes cannabidiol (CBD) and tetrahydrocannabinol (THC), two natural compounds found in plants of the Cannabis genus. Both compounds interact with your body’s endocannabinoid system, but they have very different effects. Read on to learn more about these compounds. While they may have a lot in common, some key differences determine how to use them.
Here is a high level summary of the major differences between CBD and THC:
CBD | THC | |
is legal | it depends (see below) | it depends (see below) |
produces a high | no | yes |
interacts with endocannabinoid system | yes | yes |
has side effects | yes (see below) | yes (see below) |
shows on drug test | possibly | yes |
relieves pain | yes | yes |
reduces nausea | yes | yes |
eases migraine | yes | yes |
reduces anxiety | yes | yes |
eases depression | yes | no |
decreases seizures | yes | no |
is anti-inflammatory | yes | yes |
helps with insomnia | yes | yes |
helps with psychosis | yes | no |
increases appetite | no | yes |
is used for various other conditions | yes | yes |
It’s important to note that cannabinoids will affect everyone differently. While some people may find benefits for some of the conditions listed above, others will not.
Is CBD Legal? Hemp-derived CBD products (with less than 0.3 percent THC) are legal on the federal level, but are still illegal under some state laws. Marijuana-derived CBD products are illegal on the federal level, but are legal under some state laws. Check your state’s laws and those of anywhere you travel. Keep in mind that nonprescription CBD products are not FDA-approved, and may be inaccurately labeled.
What is CBD?
CBD can be extracted from hemp or cannabis. Hemp and cannabis come from the Cannabis sativa plant. Legal hemp must contain 0.3% THC or lessTrusted Source. CBD is sold in gels, gummies, oils, supplements, extracts, and more. CBD does not produce the “high”
sensation associated with cannabis.
What is THC?
THC is the main psychoactive compound in cannabis that produces a “high” sensation. It can be consumed by smoking cannabicannabis. It’s also available in oils, edibles, tinctures, capsules, and more.
CBD vs. THC: Chemical structure
CBD and THC have the same molecular structure: 21 carbon atomsTrusted Source, 30 hydrogen atoms, and 2 oxygen atoms. A slight difference in how the atoms are arranged accounts for the differing effects on your body. CBD and THC are chemically similar to your body’s endocannabinoids. This allows them to interact with your cannabinoid receptors. The interaction affects the release of neurotransmitters in your brain.
Is CBD as powerful as THC?
Despite their similar chemical structures, CBD and THC do not have the same psychoactive effects. CBD is psychoactive, just not in the same manner as THC. It does not produce the high associated with THC. THC binds with the cannabinoid 1 (CB1) receptors in the brain, producing a high or a sense of euphoria.
CBD vs. THC: Legality
In the United States, cannabis-related laws are evolving regularly. Technically, CBD is still considered a Schedule I drug under federal law. Hemp has been removed from the Controlled Substances Act, but the Drug Enforcement Administration (DEA) and Food and Drug Administration (FDA) still classify CBD as a Schedule I drug. As of April 2023, 38 states, as well as D.C., Puerto Rico, Guam, and the U.S. Virgin Islands, have legalized the use of medical cannabis with high levels of THC.
Another 10 states allow access to limited amounts of low THC cannabis or CBD oil.
The cannabis may need to be recommended by a licensed physician. Certain states also allow licensed physicians and advanced practice registered nurses to recommend cannabis.
In addition, 24 states, as well as D.C., Guam, and the Northern Mariana Islands, have legalized the recreational use of cannabis. In these states, you should be able to buy CBD.
Before you try to buy products with CBD or THC, it’s important to research your state’s laws.
If you possess cannabis-related products in a state where they’re illegal or don’t have a medical prescription in states where the products are legal for medical treatment, you could face legal penalties.
CBD vs. THC: Medical benefits
CBD and THC have many of the same medical benefits. For example, they may help treat similar conditions and provide relief from the same conditions. However, factors like dose, frequency, and product quality may play a role in how you respond.
CBD
In June 2018, the FDATrusted Source approved Epidiolex, which is the first CBD prescription medication. It’s produced from the cannabis plant and refined into an isolate that is 99% pure CBD. It’s used to treat rare, difficult-to-control forms of epilepsy. (Epidiolex is not currently approved for any of the other conditions listed below.)
Other than that, commercially available CBD products, such as CBD oil, may be used to help with symptoms of other conditions. Learn more about the potential health benefits of CBD oil. In addition, CBD may offerTrusted Source some benefits in treating symptoms of depression, anxiety, insomnia, and schizophrenia, though it has yet to be approved by the FDA for these uses.
More research is needed to determine whether CBD can effectively treat these conditions and others. THC
The FDATrusted Source has approved two synthetic formulations of THC for treating specific conditions: nabilone and dronabinol. Nabilone (Cesamet) is FDA approved for treating chemotherapy-induced nausea and vomiting. Dronabinol (Marinol, Syndros) is FDA approved to treat nausea and vomiting caused by chemotherapy drugs. It is also approved to stimulate appetite in people with AIDS or anorexia. THC is often used to help with issues like nausea, appetite, pain, and insomnia. Recent studiesTrusted Source are looking at the potential of THC to treat fibromyalgia and other types of chronic pain.
Is THC more effective than CBD for pain?
Unlike THC, CBD binds very weakly, if at all, to CB1 receptors. CBD needs THC to bind to the CB1 receptor and, in turn, can help reduce some of the unwanted psychoactive effects of THC, such as euphoria or sedation. That said, there’s not a lot of data that compares the effectiveness of CBD and THC in terms of treating pain. In studiesTrusted Source where people reported a preference for CBD in treating chronic neuropathic pain, the potency level did not seem to increase people’s perceptions of the therapeutic effect. We also know from various studies that people who do notice a more immediate improvement in symptoms related to pain after taking cannabis tend to use products that contain more THC than CBD.
