Generally, CBD oil is made by combining an extract with a carrier fluid or oil. This question is best answered by looking at how the CBD oil was extracted. CBD oil can be extracted using CO2 systems or by using chemical solvents. Both methods produce a CBD oil byproduct that is then combined with a fluid like MCT oil, coconut oil, or olive oil so that it can be delivered to the body. Always check to make sure you know the CBD content of the products you purchase.
CBD oil is not legal everywhere. It is banned/restricted by countries such as UAE, Dubai, and Saudi Arabia. Although CBD oil is illegal in many of the US states too, some have legalized its use for medicinal purposes. While the number would be ever-changing, as of 2016 there are 17 states in the US which have legalized the use of low THC, high CBD products for medical reasons in limited situations. These states include Alabama, Georgia, Iowa, Kentucky, Florida, Mississippi, Louisiana, Missouri, North Carolina, Oklahoma, South Carolina, Wisconsin, Wyoming, Tennessee, Texas, Utah, and Virginia. It is advisable to consult your local health specialist before use.
A survey of patients seen in a tertiary epilepsy center found that 21% of patients admitted to using marijuana in the last year, and 24% of patients believed marijuana to be effective for their seizures (10). While interesting, this anecdotal observation does not rise to the level of evidence needed to evaluate a potential new therapeutic modality.
