CBD is an abbreviation for cannibidiol. Cannibidiol is a natural substance found in cannabis, also known as marijuana, and also in hemp plants. Today, you can find CBD oil in capsules, oil bases for vaporizers, tinctures, food items, and beauty products such as bath bombs or lotions.
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.
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.
Researchers are looking for answers when it comes to the full potential of CBD. What have they discovered in the meantime? So far, we know that CBD is a proven treatment when it comes to certain types of epilepsy, and early research is showing promise in regards to various anxiety disorders.
Approved to Treat Epilepsy
In 2018, the first FDA-approved drug, cannabidiol (Epidiolex), containing CBD was released on the market to treat two different kinds of epilepsy — Dravet syndrome and Lennox-Gastaut syndrome.
The FDA approved the treatment for patients as young as two years old. Studies showed it was effective in comparison to a placebo in reducing the frequency of seizures.
Though we need more research, a 2015 medical journal review article looked at CBD and its effect on multiple anxiety disorders, including generalized anxiety disorder, seasonal affective disorder, panic disorder, and post-traumatic stress disorder.
The results showed that there was "strong preclinical evidence" to support the treatment of anxiety disorders with CBD, though more research is needed on long-term dosing.
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.
Here is a list of a few potential risks and side effects that come with CBD. Some of these risks are controllable if taking CBD under the guidance of your doctor.
During drug trials for Epidiolex, the FDA determined liver injury to be a side effect of CBD. Signs of liver injury showed up on blood work used to detect early problems with the liver. You can manage this risk by only taking CBD under the supervision of your doctor.
Interaction with Other Medications
If you are taking other medications, CBD can impact their efficacy, and the dose you are taking may need to be re-evaluated by your doctor. CBD can potentially interact with other medications to cause side effects.
Because there is limited research on how CBD interacts with prescription drugs and with standard over-the-counter supplements, it is best to talk to your doctor before taking CBD if you are taking other medications.
Though not much research has looked specifically at CBD, it seems that there is a negative relationship between cannabis use and sperm count, as well as other measures of male fertility, including sperm viability and motility.
Most of these studies have focused on animal participants, and further research is needed. Experts recommend awareness around these potential side effects when prescribing cannabis to patients who are of reproductive age.
Amounts and Dosage
Because the FDA currently does not regulate CBD, there are no specific recommended doses. Doses in most clinical trials have ranged from 100 to 800 milligrams a day.
Before using any CBD product, you should speak to your doctor to come up with a safe dosage plan that works for you. This plan should also take into account your symptoms and any other medications or supplements that you may be taking.
