Our bodies are thought to produce endocannabinoids by the billions every day. “We always thought the ‘runner’s high’ was due to the release of dopamine and endorphins. But now we know the euphoria is also from an endocannabinoid called anandamide,” its name derived from the Sanskrit word for bliss, says Joseph Maroon, MD, clinical professor and vice chairman of neurosurgery at the University of Pittsburgh Medical Center. We produce these natural chemicals all day, but they fade quickly because enzymes pop up to destroy them. That’s where CBD comes in: By blocking these enzymes, CBD allows the beneficial compounds to linger.
CBD hemp oil has a huge range of potential health benefits and uses, including reducing pain, soothing anxiety, fighting chronic diseases, improving mood, eliminating depression, preventing inflammatory arthritis, protecting the immune system, balancing the metabolism, aiding sleep disorders, and healing the skin, among others. CBD oil can also be used in many different ways and has a variety of applications for natural health.
Non-THC CBD oils can be highly effective, and are suitable for employees who face random or routine drug tests. Our top pick for this category is the Medterra CBD Oil Tincture, which contains 99.6% CBD and MCT oil (also known as coconut oil extract) without any traces of THC. The oil is derived from hemp plants that are free of GMOs and pesticides, as well. All third-party testing results for the oil are accessible through Medterra’s official product page.
Scott Shannon, MD, 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 His study, as yet unpublished, found “a fairly rapid decrease in anxiety scores that appears to persist for months,” he says.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.”
Chronic Pain: The body’s ECS plays a role in alleviating and managing pain, so CBD oil can work as a supplement for individuals with medical conditions that cause chronic pain, such as arthritis and multiple sclerosis. CBD oil also increases levels of adenosine in the brain; adenosine is a neurotransmitter that aids cardiovascular function and eases painful inflammation.
The studies on CBD for headache pain are still in their infancy, but with promising results so far. A 2017 study published in the Cannabis and Cannabinoid Research Journal worked with 26 people who were experiencing rebound headaches. The pain management results were better for the cannabis-nabilone formula over either ibuprofen or nabilone alone. (As a nerdy side note, the article is a great read if you’re interested in the history of cannabis as a pain reliever.)
CBD may offer an option for treating different types of chronic pain. A study from the European Journal of Pain showed, using an animal model, CBD applied on the skin could help lower pain and inflammation due to arthritis. Another study demonstrated the mechanism by which CBD inhibits inflammatory and neuropathic pain, two of the most difficult types of chronic pain to treat. More study in humans is needed in this area to substantiate the claims of CBD proponents about pain control.

Although several clinical studies focused on the health effects of CBD, the results available so far were not enough to convince the FDA to approve it as a drug. The FDA does not agree with its use as a dietary supplement either, but as long as sellers publish the appropriate disclaimers (like those on the CBDPure website and labels), it’s not up to them.
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.
