Is CBD legal?The 2018 Farm Bill removed hemp from the legal definition of marijuana in the Controlled Substances Act. This made some hemp-derived CBD products with less than 0.3% THC federally legal. However, CBD products containing more than 0.3% THC still fall under the legal definition of marijuana, making them federally illegal but legal under some state laws. Be sure to check state laws, especially when traveling. Also, keep in mind that the FDA has not approved nonprescription CBD products, and some products may be inaccurately labeled.
Research exploring the benefits of cannabidiol (CBD) oil is still at a relatively early stage. However, more and more studies have started to demonstrate CBD’s potential therapeutic effects for a variety of conditions.
Cannabidiol (CBD) is a compound from the cannabis plant. Manufacturers extract CBD from the cannabis plant and dilute it with a carrier oil to produce a CBD oil. Many types of varying strengths are available.
Keep reading to learn more about the research investigating the benefits of CBD oil, which conditions it may help treat, and how effective it is.
CBD is one of several active compounds in the cannabis plant. Typically, CBD products do not contain the psychoactive ingredient tetrahydrocannabinol (THC). The absence of THC means that a person will not experience euphoria or a “high.”
Always check labels carefully because some CBD products may contain up to 0.3% of THC.
Extracting CBD and diluting it with a carrier oil creates the popular health product CBD oil. CBD exists in many other forms, such as topicals, capsules, and gummies.
Much of the research into CBD oil focuses on the active ingredient CBD.
By knowing which conditions CBD can help, a person may consider trying CBD oil to alleviate specific symptoms.
CBD oil may be beneficial for several conditions, including:
- Anxiety: A 2019 study on Japanese teenagers indicated that taking CBD oil orally can help reduce feelings of social anxiety.
- Insomnia: According to Current Psychiatry Reports, medium and high dosages of CBD can have a sedating effect. This means CBD oil may help with insomnia and people who have trouble falling asleep.
- Epilepsy: The
Food and Drug Administration (FDA)have approved the use of Epidolex, which contains CBD to treat people who have two rare and severe types of epilepsy. Researchsupporting this indicates that CBD oil and CBD have the potential to reduce seizures. A person may wish to discuss this with their doctor.
- Multiple Sclerosis (MS): One symptom of MS is spasticity, which causes the muscles to feel stiff and may lead to difficulty moving. Research suggests that oral CBD spray may help to reduce spasticity. However, scientists need to conduct further research to confirm this.
- Chronic pain: An
earlier studyexamining the effects of CBD on pain and inflammation found that it may reduce pain.
- Acne: CBD may reduce acne. A
2014 studyfound it can have a positive impact on human sebocytes. These are the cells that cause sebum that may cause spots. Using topical CBD oil may be beneficial.
- Neuroprotection: One
reviewhighlights that oral administration of CBD can have neuroprotective properties against conditions such as Alzheimer’s disease.
Some people may try CBD oil and find it does not work for them. There are are several reasons why this might happen:
- The oil is not from a reputable source: A person must purchase their CBD oil from a reputable source. This ensures that it contains the correct amount of cannabinoids and does not contain any other chemicals. Most reputable companies will have COAs (certificate of analysis) on their websites or available upon request. A COA is a document containing third-party laboratory testing results for the CBD they use. This ensures that the product is of the correct potency and does not contain any contaminants, such as pesticides, mold, and traces of metals.
- Incorrect dosage: The risk of overdose using CBD is extremely low. If the amount a person consumes does not alleviate the problem, they may wish to raise the dosage slightly. One study found that people with bipolar disorder who consumed up to
1,200mga day for 24 days did not experience any side effects.
- Increase in tolerance: Similarly, a person may require a higher dosage of CBD oil if they have built up a tolerance to their usual dose. Also, a person may need a higher dose of CBD oil if they use cannabis recreationally.
- Unsuitable administration method: For some people, their chosen method of administering the CBD oil may not be the best way to optimize treatment. Trying alternative methods may help. A person can take CBD oil orally, sublingually, or topically.
- Short-term use: In some instances, CBD oil may not work straight away. A person may need to use CBD oil for a while before observing any effects.
- It is out of date: CBD oil has a shelf life of 1–2 years. Although using old CBD oil is unlikely to make a person sick, it may lose its potency.
A person thinking about using CBD oil should consider what type is most suitable. There are three types:
- Full-Spectrum: This means that the product contains all the cannabinoids that occur naturally in the cannabis plant. It also contains trace amounts of THC.
- Broad-Spectrum: Broad-spectrum CBD contains all the cannabinoids but is THC-free.
- Isolated CBD: This form of oil is the purest of the three. Products that consist of isolated CBD do not contain any other cannabinoids or cannabis plant compounds.
Although CBD oil has many benefits, there are a few risks a person may want to consider before taking it.
