'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.’

Under federal law, cannabis (from which both CBD and marijuana are derived) is illegal everywhere, although the laws against it aren’t generally enforced in states that have legalized marijuana. Some manufacturers claim that CBD culled from legally imported industrial hemp, which has little to no THC, is fine to ship across the U.S., but many experts disagree, noting that because hemp comes from the same species as marijuana, cannabis sativa, all CBD falls under the DEA’s Schedule 1 designation. “This creative interpretation of the law runs afoul of reality,” says the Brookings Institution, a Washington, DC, think tank.
CBD has proven neuroprotective effects and its anti-cancer properties are being investigated at several academic research centers in the United States and elsewhere. A 2010 brain cancer study by California scientists found that CBD “enhances the inhibitory effects of THC on human glioblastoma cell proliferation and survival.” This means that CBD makes THC even more potent as an anticancer substance. Also in 2010, German researchers reported that CBD stimulates neurogenesis, the growth of new brain cells, in adult mammals.
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.
CBD isolate is pure CBD, extracted and purified until none of the plant’s other constituent compounds remain. It has been isolated down to just the CBD molecule. This purity and potency is why it’s the preferred treatment for patients needing unadulterated doses of CBD and nothing else. It has no other active ingredients and its purpose is simply to deliver therapeutic doses of CBD. CBD isolate products often come as a white powder or a mix with a oil.
Tetrahydrocannabinol is the most abundant cannabinoid in most medical and recreational marijuana strains. However, in hemp THC is a minor constituent and appears only in trace amounts under 0.3% by dry weight, as required by the U.S. government for hemp products. THC mimics the action of anandamide, a neurotransmitter naturally produced in the human body, and binds to CB1 receptors in the endocannabinoid system found mostly in the brain. The extremely low levels of THC in hemp make hemp oil non-psychoactive and safe for all ages to use.
A study published by David Cheng, Postdoctoral Scientist, Neuroscience Research, University of New South Wales, NSW, Australia, says that CBD has a potential as a preventive measure against symptoms of Alzheimer’s. This presents yet another exciting development for medical researchers, given the persistent challenges to finding effective solutions for this condition.
"If it proved effective for anxiety, depression and panic disorder, it may have other effects as well that could be useful and beneficial [but] this is a really early stage," says David Shurtleff, the acting director of the National Center for Complementary and Integrative Health. His organization's stance: "Take it one step at a time and do the work and really state where we are right now with the research," he says.
The same terms could be applied to what's actually in CBD products. While some do contain CBD, others (often marketed as "CBD-rich hemp oil") may have barely any, Asquith says. And depending on state laws, they can include varying levels of THC too – a combination shown to have some benefits, but also drawbacks, of course, if you're not looking for a high. "People will play all these games with the numbers because the consumers aren't really educated in this space yet and it's easy to get taken advantage of," he says. "It's the milligrams of the actual CBD molecule that matter."
Essential fatty acids are necessary for maintaining heart and cardiovascular health. The two primary essential fatty acids — Omega 3 and Omega 6 — are ideally consumed at a ratio of around 3:1. Unfortunately, in the typical American diet, that ratio is close to 25:1. Full-spectrum hemp oil offers the two essential fatty acids in the optimal 3:1 ratio.
CBD vaporizer oils can be used in a vaporizer of your choice. They offer a healthy way of inhaling your daily dose of the CBD supplement. Vaping is a very direct way of ingesting CBD oil. When you vape, the CBD enters the lungs and goes directly into the bloodstream, completely bypassing the digestive system. This method allows for greater bioavailability.
