Research surrounding CBD is ongoing, and there are many questions that researchers do not have the answers to yet, such as whether or not the means of taking CBD impacts the risks or efficacy. Some common means of taking CBD include inhaling through a vaporizer, ingesting through food, or taking orally as a pill.
Research into some of these claims is ongoing, and there is still a lot about CBD that we don’t know but researchers are trying to find out.
Interaction with Other Medications
Unlike its cousin THC, CBD is not intoxicating or psychoactive. Proponents of CBD oil and other CBD products claim that it can be used to treat conditions such as chronic pain, inflammation, migraines, epilepsy, autoimmune diseases, depression, and anxiety.
CBD oil may also increase liver enzymes (a marker of liver inflammation). People with liver disease should consult their healthcare provider before taking CBD oil and use it with caution. Regular blood liver enzyme level checks are recommended.
As such, some of these health claims are better supported by research than others.
In most of the studies, lower doses of CBD (10 milligrams per kilogram, mg/kg, or less) improved some symptoms of anxiety, but higher doses (100 mg/kg or more) had almost no effect.
Cytochrome P450 (CYP450) is an enzyme in your body that breaks down certain drugs. But CBD oil can block CYP450 from working the way it normally does. CBD oil can either make some drugs you take have a stronger effect than you need or make them less effective.
CBD oil can interact with some medications, including those used to treat epilepsy.
CBD's exact mechanism of action is unclear.
CBD oil contains CBD mixed with a base (carrier) oil, like coconut oil or hemp seed oil. The bottled CBD oil is called a tincture and is sold in different concentrations.
