side effects of cbd oil

CBD oil contains CBD mixed with an inert carrier oil, such as coconut oil or hemp seed oil. The bottled oil, called a tincture, is sold in various concentrations. There are also CBD capsules, CBD gummies, and under-the-tongue CBD sprays.

CBD oil comes as full-spectrum oils or in forms that contain CBD isolates. Unlike isolates, which contain CBD only, full-spectrum oils contain a variety of compounds found naturally in the cannabis plant, including proteins, flavonoids, terpenes, and chlorophyll. Alternative practitioners believe these compounds offer more substantial health benefits, although there is no clear evidence of this.

CBD oil may also increase liver enzymes (a marker of liver inflammation). People with liver disease should use CBD oil with caution, ideally under the care of a doctor who can regularly check blood liver enzyme levels.

In June 2018, the U.S. Food and Drug Administration (FDA) approved Epidiolex, a CBD oral solution used for the treatment of certain rare forms of epilepsy in children under 2—Dravet syndrome and Lennox-Gastaut syndrome. Both are exceptionally rare genetic disorders causing lifelong catastrophic seizures that begin during the first year of life.

However, the effect of CBD on each addiction type was often very different. With opioid addiction, for example, CBD showed little effect in minimizing withdrawal symptoms in the absence of THC. By contrast, CBD on its own appeared effective in minimizing drug-seeking behaviors in users of cocaine, methamphetamine, and other psychostimulant drugs.

Although CBD has been deemed safe by the WHO and other health organizations, not enough experiments have been done to identify if there are any populations for whom CBD is unsafe. Instead of taking that as a free pass to tell everyone to take CBD (like most other CBD companies), we think this makes it even more important to scour the scientific literature for any warning signs. Because we value your safety first, we put together a list of all the conditions we could find that might deserve special consideration.

Now that Epidiolex has opened the door for CBD’s acceptance by the medical community, you can expect to see more prescription uses for CBD in the future. However, because of the way our medical system is structured, the stamp of approval can only be gained after a long period of costly clinical testing. This testing is paid for by companies that can patent and profit from the results.

For most patients, these side effects occurred during the first few weeks while they were quickly raising their dosage. The symptoms typically subsided after their dosage stabilized, and lowering the dose was also an effective way of decreasing undesirable side effects. If you’re experiencing any of these side effects on your current CBD product, you might experiment with waiting it out a week, lowering your dose or trying a different type of product entirely.

So we thought we’d compile all the negative scientific evidence into one handy guide, to help you decide whether CBD is right for you. We’ll cover the different side effects you might encounter and what they could mean, as well as what current research says about trying CBD if you are:

Clinical evidence for CBD oil

Even a critical review by the World Health Organization (WHO) recently reported that CBD is a promising treatment for a number of medical conditions, is well tolerated, has a good safety profile, and doesn’t appear to be a risk for abuse, dependence, or other public-health related problems. In other words, even the WHO thinks CBD is A-OK.

You’re pregnant or breastfeeding. (Could be important) When pregnant or breastfeeding, a mother shares everything with her growing child. Active molecules in a mother’s bloodstream can pass into her child’s body through both the placenta and breast milk. Broad screening reveals that cannabinoids can be detected in the umbilical cords and stools of newborn children. And low levels of cannabinoids can be detected in breast milk from regular cannabis users . It’s currently uncertain if/how CBD affects a developing baby, but it’s safest to minimize exposure to cannabinoids (and a wide variety of other foods, products, and medications) while pregnant or breastfeeding. If you are currently pregnant or breastfeeding and use CBD to manage anxiety or another health issue, discuss the tradeoffs with a medical professional.

“Since discovering the endocannabinoid system (ECS) in the body in the 1990s, CBD has been researched more extensively. The ECS is a central regulatory system restoring normal balance and homeostasis in a range of human physiologic systems throughout the body and brain and has cannabinoid receptors and chemicals in its function,” explains Dr. Matharu-Daley.

Some common side effects when using CBD include drowsiness and sedation. This is also considered a benefit, but Dr. Jas Matharu-Daley, a physician and chief medical officer for a CBD brand, notes that the effects might be too strong if you’re also taking CBD with other sedating medications.

CBD—the abbreviation for cannabidiol, a substance that’s generally derived from the hemp plant—has skyrocketed in popularity over the last five years. In fact, according to some research, “CBD” as a Google search term remained stable from 2004 to 2014 but has since ballooned by up to 605%.

What Is Cannabidiol (CBD)?

Generally speaking, CBD is considered a safe substance when applied topically or taken orally. There are, however, some potential side effects to keep in mind when using this substance, the majority of which are mild.

The most comment side effects of CBD include drowsiness, gastrointestinal issues, dry mouth, reduced appetite, nausea, and interaction with other medications. Those are outlined in detail below.

“If the CBD is from a reputable source and one that has been inspected by a third-party independent lab, the content of CBD is more reliable,” notes Dr. Matharu-Daley. “The CBD should be organically grown, free of pesticides and heavy metals, and not sourced in food which can affect absorption. Generally, CBD is safe and side effects are few at low doses.”
