Since some CBD oils contain trace amounts of THC, you should avoid driving or using heavy machinery when taking CBD oil, particularly when first starting treatment or using a new brand.
CBD’s exact mechanism of action is unclear. Unlike THC, CBD has a relatively low affinity for cannabinoid receptors in the brain. These are the molecules to which THC binds to elicit its psychoactive effects.
According to a 2017 study in the Journal of the American Medical Association, only 30.95% of CBD products sold online were correctly labeled. Most contained less CBD than advertised, while 21.43% had significant amounts of THC.
CBD oil may reduce the risk of heart disease by alleviating hypertension (high blood pressure) in certain people, suggests a 2017 study in JCI Insight.
Medical marijuana is frequently prescribed to people with intractable (treatment-resistant) pain, including those with terminal cancer. There is some evidence that CBD contributes to this benefit.
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 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.
For many of us, it may seem as though cannabidiol (CBD) sprang up out of nowhere. Within a few short years, this obscure molecule found in cannabis plants has moved from near-anonymity to a cure-all embraced by millions.

Sometimes CBD products don’t contain any CBD at all — in which case you won’t experience any effects, positive or negative.
Although it’s hard to imagine all the different side effects you might experience from contaminated or synthetic products, the worst effects of dishonest CBD products could be long-term damage to your body that you won’t immediately experience as a side effect.
You’re surrounded by germs. (Not enough evidence) Some people hypothesize that CBD’s excellent immune-system soothing capabilities could accidentally let a few stray germs slip past your immune system’s defense. Scientists have tested this by exposing mice to the bacterium that causes Legionnaires’ disease and measuring their ability to fight the infection. Although moderate doses of CBD didn’t impair their immune systems, they were worse off on high doses equivalent to 1,000 mg for a 150lb person . If you’re currently taking higher doses of CBD and also sharing space with a bunch of coughing people, it might be a good idea to temporarily decrease your CBD dose.
