Pure CBD cannabis oil derived from hemp contains only trace amounts of THC. Hemp is grown from specific cannabis varieties that naturally possess higher levels of CBD. These hemp stalks and hemp seeds produce organic hemp oil that is naturally rich in cannabidiol. Some genetic varieties of hemp contain higher concentrations of pure CBD than others.
“If you’re taking Prozac or some other medication, you really need to think carefully about what you’re doing, because it can harm you, and you should talk to your doctor about it,” says Blessing. Blessing does note that while the drug interactions are potentially very serious, the doses in consumer CBD products are so low that the risk is likely minimal. Regardless, the fact that CBD has drug interactions should indicate that it is, at least sometimes, in some doses, actually doing something.
Still, as the saying goes, absence of evidence isn’t necessarily evidence of absence, and there’s a reason we don’t have a ton of solid research on CBDs yet — “to study it, we need a good source, ” said Ziva Cooper, who is an associate professor at Columbia University and was on the National Academies committee. CBD is hard to get because it’s still technically a Schedule I drug, which limits its availability, Cooper said.
People claim that cannabis oil can be used to treat a wide range of conditions, though evidence to back up these claims is often lacking. For example, according to Medical News Today, people use cannabis oil for conditions ranging from pain to acne; some even claim the oil can cure diseases like Alzheimer's and cancer. (But again, there is no clinical evidence to support these claims.)
I was so excited to try this but it hasn’t helped my back pain whatsoever. I’ve been taking it for 2 months and I’m going to give it one more month. I am taking the 500 and have doubled the dose making it 1000 mg. So disappointed.I thought in the beginning that it was giving me a little more energy. Maybe it has. I love the company. It is so easy to order and it’s shipped right away.
Cooper recently got funding from the National Institutes of Health for a study looking at cannabinoids — including CBD in isolation — as a substitute for opioids, and numerous other clinical trials of CBD are underway. It will be several years before results are available, but these studies should help clarify both what benefits the substance may provide and any side effects it may come with. Most of the adverse effects so far associated with cannabis, such as impairments in short-term memory, coordination and judgment,2 come from products that contain THC as well as CBD, Cooper said, but we need to do more studies to find out for sure whether CBD has fewer risks. Studies are also needed to identify the best way to administer and dose CBD. “I get emails from people asking me what dose of CBD to use, and the truth is, we really don’t know,” Cooper said.
CBD oil contains CBD (and often other active compounds) in a carrier oil. There are a number of forms of CBD oil, including softgel capsules, tinctures, and under-the-tongue sprays. Some forms of CBD oil can also be applied directly to the skin, in the form of products like creams and salves. The concentration of CBD varies from product to product.
Researchers like Blessing are legitimately excited about CBD. It shows real promise in treating previously intractable disorders like schizophrenia, and without the destructive side effects of existing drugs. Still, that doesn’t mean CBD is harmless. Research on drug interactions with CBD is in its infancy, but what is known within the medical community is that CBD can cause serious problems for people taking certain classes of drugs, namely SSRIs (a group of antidepressants including Zoloft and Prozac) and opioids.
When considering our different dietary hemp products, know that they all come in two strengths. Our Original Hemp blends (Hemp Classic, Hemp Complete, & Signature Blend) all have 250+mg of cannabinoids per fluid ounce, and our concentrated blends have 1,500+mg per fluid ounce, six times the potency of our traditional oils. We’ve found that sometimes less is more, but nevertheless, some people like to take very large serving sizes of our hemp extracts.
This is true despite the fact that unlike marijuana, hemp contains only trace levels of THC (tetrahydrocannabinol), the chemical component that gives marijuana its euphoric qualities. Instead, hemp is primarily known for its fibers, commonly used to make rope, fabrics, auto parts, industrial materials, and a variety of other products. Hemp is also known for its highly-nutritious seeds (a.k.a. hemp hearts), which have been shown to benefit heart health, skin diseases, and more.
The Cannabis Health Index (CHI) is an evidence-based scoring system for cannabis (in general, not just CBD effects) and its effectiveness on various health issues based on currently available research data. Refer to cannabishealthindex.com for updated information. Using this rubric and based on twenty-one studies, cannabis rated in the possible-to-probable range of efficacy for treatment of depression.
Vapor Distillation™: Also sometimes called thermal extraction, vapor distillation uses hot air to safely vaporize the full spectrum of chemical components at high concentration from the buds, and then the vapor is distilled into CBD oil. This method also activates the cannabinoids by removing an extra carboxyl ring from their molecular chain (a chemical reaction called decarboxylation), enabling them to interact directly with CB receptors for maximal medicinal value.
Naturally, scientists wanted to see if CBD oil had any anticancer properties. As a result, they performed several animal studies using it. However, it should be noted that the findings don’t fully apply to humans. In fact, they merely suggest what possible effects CBD might have when it comes to dealing with cancer. With that in mind, additional human studies would help conclude if CBD oil has an effect on cancer cells in humans.
Cost is another consideration. Most CBD oils are sold in concentrations of 300 to 750 mg, although this may range from less than 100 mg to more than 2,000. A good indicator of price-point is the cost per milligram. Low-cost CBD oils usually fall between five and 10 cents per mg; mid-range prices are 11 to 15 cents per mg; and higher-end oils cost 16 cents per mg or higher. Given these varying per-milligram costs, a bottle of CBD oil may be priced anywhere from $10 or less to $150 or more.

Understanding CBD’s analgesic, or pain-relieving, interactions with the ECS can shed light on CBD’s other interactions and effects. Importantly, the ECS participates in our bodies’ pain processing, but when CBD is introduced to our ECS, it stops the body from absorbing a pain-regulating compound known as anandamide — one of our body’s’ own natural cannabinoid molecules. Inhibiting the absorption of this compound shunts excess quantities into the bloodstream that in turn reduces pain. One study has revealed that CBD targets alpha-3 (α3) glycine receptors to suppress chronic pain and inflammation associated with dysfunctional glycine receptors, which are an important target for pain processing in the spine. In both humans and animal models, CBD has been shown to have a variety of anti-inflammatory properties.
Regular weed comes from the cannabis plant, while CBD is derived from hemp. What's the difference? "The legal definition of hemp is a cannabis plant that has less than .3 percent THC in it," says Trista Okel, founder and CEO of CBD product retailer Empower Body Care. "That is the only legal differentiation between hemp and marijuana." All pure CBD oil will have less than .3 percent THC but will be full of the (alleged) anxiety- and pain-reducing properties.

“With CBD, they’re finding a certain level of anxiety and stress reduction that other things hadn’t afforded them or a similar effect but without the side effects,” she said. “My concern is about the potential reliance on the CBD doing the job for you rather than actually doing the meditative work. So maybe it could be like a boost that you could eventually let go of, instead of doing CBD plus meditation for the rest of your life.”
Those warning letters aside, there’s not a lot of federal oversight right now over the claims being made or the products that are being sold. Cohen warned against buying CBD products online, because “there’s a lot of scams out there.” Yet his clinic sells CBD, and he admits, “I say ‘Don’t buy online,’ but ours is worth doing, because we know what we’re doing. We ship all over.”
Management of chronic pain is another application for which CBD is ideally suited, and it works in a number of ways. It and other non-THC cannabinoids found in hemp flower-bud extracts work to block pain-conducting nerve impulses, which reduces your perception of pain. Stimulation of CB1 in the brain increases dopamine, which counteracts pain. Just as importantly, these same chemical substances reduce inflammation, the driving force behind pain, which allows healing to occur.
Answering the question “what is CBD oil” would be incomplete without mentioning the many CBD oil benefits. In addition to positively affecting the endocannabinoid system, CBD has been the focus of more than 23,000 published studies about cannabinoids in relation to various medical indications including anxiety, epilepsy, inflammation, cancer and chronic pain to name few. You can even find CBD for pets that is specially formulated to safely allow your pets to experience the natural benefits of CBD.
