Dosage is important, because CBD can have side effects—the most common are tiredness, diarrhea, and changes in appetite and weight—so it’s best not to take more than you need. As CBD becomes more prevalent, says J. Michael Bostwick, M.D., a psychiatrist at Mayo Clinic in Rochester, MN, “I’m reasonably certain new kinds of side effects will emerge.”

Extracts of CBD—either from marijuana or hemp (a cannabis variant that is essentially free of THC)—are sold as an oil or in tinctures. You can also get CBD via a transdermal patch, capsule, sublingual spray, gel, cream, or vapor. Some contain pure CBD extract (or so they say); others—particularly if you’re in a state where recreational marijuana is not legal—will contain hemp extract, which includes CBD as part of its makeup. As of this reporting, recreational marijuana is legal in nine U.S. states and medical marijuana in 29. Don’t miss these 50 weird things that are banned in the United States.


Your statement about cannabis being illegal is misleading. Cannabis is the plant/herb itself. The difference in what is legal vs illegal to all states is the flower of the herb containing THC. Anything < 0.3% is regarded as HEMP as the constituents lack enough of the THC compound to create the psychoactive effect. MARIJUANA is known for the psychoactive effects. They are both forms of CANNABIS.
Full spectrum CBD also contains a variety of essential vitamins, minerals, fatty acids, protein, chlorophyll, terpenes, flavonoids, and fiber. When referring to CBD in the hemp plant, it’s important to understand that hemp contains a large number of cannabinoids (in trace amounts), but the main compound is cannabidiolic acid (CBDa). As CBDa is more abundant in the hemp plant, firms must decarboxylate the oil. This process heats the oil and changes CBDa into CBD.
Unfortunately, you don’t. Even though more than half of all U.S. states now allow marijuana for medicinal purposes—and nine of those, plus Washington DC, allow it for recreational use—the Drug Enforcement Agency still views CBD as a banned substance and therefore doesn’t regulate it (since, in the eyes of the law, CBD shouldn’t be on the market). “I can start a company, put oil in a jar and sell it as CBD oil,” says McLaughlin—and no one has to vouch that what’s in there is for real. You have only the manufacturers word for it.
In isolate form, CBD is separated from other cannabinoids found in hemp and cannabis. Previously, users and researchers believed that CBD isolates were more potent than full spectrum CBD hemp edibles. But that myth was eventually proven wrong by different studies performed in recent years. Therefore, full spectrum CBD oil is more effective than CBD isolate.
Another concern is about medications with which CBD might interact. This won’t be an issue with most drugs, says Sunil Kumar Aggarwal, M.D., Ph.D., a palliative medicine physician and scientist who studies cannabis and integrates it into his Seattle medical practice. The exceptions are blood thinners, IV antibiotics, and other drugs whose exact dosing is crucial and must be monitored closely, he says. (Of course, if you have a health problem, talk to your doctor before using CBD, and never take it instead of seeing your physician for a serious condition.)
So, many of CBD's popularized benefits aren't well-proven. But are there any harms in trying CBD-containing products? In a word, yes. While any reported side effects from CBD alone are minor (think dry mouth and dizziness), they can be serious if the CBD products interact with other medications, experts say. Since CBD is metabolized by the same enzyme in the liver that metabolizes many conventional medicines and supplements, the chemical can cause the levels of other drugs in the system to rise; in some cases – like for those taking a drug to prevent their bodies from rejecting a donor organ – to a deadly level, Tishler says.
Officially, marijuana is deemed as Schedule I herbal substance by the U.S. Drug Enforcement Administration, meaning the drug offers "no currently accepted medical use and a high potential for abuse," according to the federal government. That categorization was adjusted after the passage of the 2018 Farm Bill, which included a provision that separated hemp from marijuana, as noted in the Controlled Subject Act.
Since it is non-toxic and non-flammable, supercritical CO2 is preferable over chemical solvents like butane, hexane, and acetone, which can linger in the extracted oil if not purged correctly, rendering the oil toxic. It has also been noted that botanical essential oils extracted using supercritical CO2 are truer to the scent of the original plants than in other forms of extraction, meaning more of the plant’s chemical structure is retained in the oil with the use of CO2.
Before we directly compare the both, let’s break down what each is. Full spectrum CBD oil comes with all the cannabinoids present in hemp. If you see full spectrum hemp CBD oil for sale, it’ll include many cannabis compounds such as Cannabicycol (CBL), Tetrahydrocannabivarin (THCV), Cannabinol (CBN), Cannabichromevarinic Acid (CBCVA) and more. It also contains a very small amount of THC, (.3%, as is legally allowed).
Because of recent legislation legalizing marijuana, CBD product sales have grown. People are more open to the medical benefits of the drug, especially now that CBD can be separated from THC. With popularity and interest on the rise, manufacturers have expanded their product offerings. Products typically come in two types: nutritional or medicinal products and beauty products.
For example, it eases pain and inflammation. It can also help treat anxiety, epilepsy, and some types of cancer. These are just a few of its many benefits. CBD oil provides relief without the psychoactive effects created by THC. Without the buzz, there are more medical uses for the drug. In order to separate CBD from the THC and other parts of the plant, you have to extract it. The end product is CBD hemp oil.
ISA HERRERA HEARD IT from her patients first. "I have less pain." "I'm having less anxiety." "My menstrual cramps are less intense," they told the New York City physical therapist about taking CBD oil, a product containing cannabidiol, one of many chemicals found in the cannabis plant. "I was like, 'I need to find out more about this,'" recalls Herrera, who specializes in integrative pelvic floor therapies.
Lab techs use state of the art equipment to create phase changes in carbon dioxide by utilizing temperature and pressure. The carbon dioxide is cooled and compressed to upwards of 10,000 psi – by comparison your car tire is pressurized to about 300 psi. When compressed to these extremes, CO2 becomes ‘supercritical’, which simply means that it converts to liquid when placed under extreme pressure.
If you haven’t been bombarded with CBD marketing or raves about it from friends, get ready. This extract—which comes from either marijuana or its industrial cousin, hemp—is popping up everywhere. There are CBD capsules, tinctures, and liquids for vaping plus CBD-infused lotions, beauty products, snacks, coffee, and even vaginal suppositories. Already some 1,000 brands of CBD products are available in stores—and online in states that don’t have lenient cannabis laws. This is a tiny fraction of what’s to come: The CBD market is poised to exceed $1 billion by 2020, per the Chicago-based research firm Brightfield Group.
Although CBD oils aren’t regulated by the FDA, purchasing products stateside from one of the nine states where recreational and medical cannabis use is legal will likely result in a higher-quality product than buying one made with hemp-derived CBD oil imported from abroad, says Martin Lee, director of Project CBD, a nonprofit that promotes medical research into CBD.
The key difference between hemp and marijuana is that hemp contains practically zero THC. In fact, in order to be classified as hemp, a cannabis plant must contain less than 0.3% THC by volume. This is really important because it’s actually the reason why hemp products are legal to buy, sell, and ship. If they don’t get you high, then why would they be illegal?

THC-dominant edibles (like chocolates) can carry an even higher risk. “It can take one or two hours to feel an effect from ingestion as opposed to a few seconds from inhalation,” says Dr. Bonn-Miller. “This makes titration very difficult.” Add to that, an edible is made to taste good. So you can easily eat more than you should in the course of a few minutes—and end up feeling negative effects hours later.
Most human studies of CBD have been done on people who have seizures, and the FDA recently approved the first CBD-based drug, Epidiolex, for rare forms of epilepsy. Clinical trials for other conditions are promising, but tiny. In one Brazilian study published in 2011 of people with generalized social anxiety disorder, for example, taking a 600-mg dose of CBD (higher than a typical dose from a tincture) lessened discomfort more than a placebo, but only a dozen people were given the pill.

That being said, though, CBD isolate still has a very relevant place in the cannabis market. A lot of people, for instance, use it to concoct their own personal daily CBD remedies – they mix the pure powder with oil, or they add it into their coffee, or they make edibles out of it. Since it comes in an easily-measurable powder, it’s a great option for those individuals who are trying to calculate exact personal dosages of CBD medication by the milligram.

Scott Shannon, M.D., assistant clinical professor at the University of Colorado, recently sifted through patient charts from his four-doctor practice to document CBD’s effects on anxiety. His study, as yet unpublished, found “a fairly rapid decrease in anxiety scores that appears to persist for months,” he says. But he says he can’t discount a placebo effect, especially since “there’s a lot of hype right now.”

Cannabinol results from the degradation of THC. There is little of it in the fresh plant, but decarboxylation often raises the amount of CBN in the plant as an effect. CBN is only mildly psychoactive and has a higher affinity for the CB2 receptor than the CB1 receptor, linking CBN to the body’s immune system. In hemp oil, CBN is present in levels of 0.2% or lower.

Yes: CBD extracts can’t always be trusted. A 2017 JAMA paper reported that almost 70 percent of all CBD products sold online do not contain the amount of CBD stated on the label. Of the 84 products bought from 31 different companies, 42 percent contained a higher concentration of CBD oil than the label claimed, and 26 percent of the products contained less than the label claimed. The remainder of products contained the labeled amount—give or take 10 percent.

‘CBD has proven anti-anxiety effects and may be helpful in depression, based on anecdotal reports,’ says Dr Gordon. ‘I use high CBD prescription cannabis medicine products as part of a mental health protocol with my patients suffering with anxiety and depression. The antidepressant effects of CBD have been shown in animal models, but we now need large, depression-specific studies in humans as the next step.’
'If the Patient Information Leaflet that comes with your medication says to avoid grapefruit juice, for instance, then do not take CBD, as the same type of interaction can affect circulating blood levels of your medicine. Even if the leaflet does not mention grapefruit juice, you should still check with your doctor before taking CBD. You should also not take CBD if you are pregnant or breastfeeding.’
After seasonal harvests of specific cultivars, these high-CBD hemp crops are put through a specialized solvent-free extraction process to yield a hemp oil that is naturally high in cannabidiol. This high CBD oil is different from hemp oil that is used in cooking. This pure hemp extract is then tested for safety, quality, and cannabinoid content before being exported to our processing facilities in the United States. Importing any cannabis or hemp product into the United States is a complicated and serious task, so we leave nothing to chance before our high-CBD hemp oil makes its journey across the Atlantic Ocean.
