Cannabis pills containing only CBD and not THC were sold legally for the first time in Europe in 2015.
Cannabis oil is legal to buy and consume in the UK, with CBD oil first stocked in UK shops in 2018.
What is CBD oil?
Studies have also shown that CBD oil has benefits for people with epilepsy, mental health disorders such as anxiety and depression, and helping people quit smoking. 
By activating receptors such as adenosine, serotonin and vanilloid, CBD can affect your body temperature, inflammation and perception of pain.
Unlike the psychoactive tetrahydrocannabinol (THC) substance which gives marijuana users the “high” feeling, CBD oil contains less than 0.2% THC. Because CBD is not psychoactive, it does not change a user’s state of mind, but it does appear to produce significant changes in the body.
Jackson says that Realm of Caring does not offer medical advice, and it does not grow or sell cannabis. Instead, it offers education for clients and doctors about cannabis, based on its ever-growing registry of CBD users, their conditions, side effects, and administration regimen. “We are basically educating,” says Jackson. “We want you to talk to your doctor about the information you receive."
The U.S. Food and Drug Administration (FDA) approved the first CBD medication in 2018, for treating childhood epilepsy. Currently, there is no other FDA-approved CBD medication for diabetes or any other condition, according to the FDA. In December 2018, the FDA said it was unlawful under the Federal Food, Drug, and Cosmetic Act to sell food or dietary supplements containing CBD. In April 2019, the FDA stated that it would be taking new steps to evaluate cannabis products, and it held a public hearing about cannabis products in May 2019.
Scientific Studies on CBD and Type 2 Diabetes, and Barriers to Research
The trendy complementary treatment is rising in popularity. Here’s what you need to know before you use CBD to manage type 2 diabetes.
That there are so few studies of CBD in people with type 2 diabetes has to do with a lack of focus on CBD as an individual component. Historically, cannabinoids (a group of chemicals in the cannabis plant) have been lumped together, including CBD, THC, and more than 100 others. The 1970 U.S. Controlled Substances Act classifies cannabis as a Schedule 1 drug with the highest restrictions. Currently, 33 states and the District of Columbia allow cannabis for medical use and 11 states allow cannabis for recreational use.
Heather Jackson, the founder and board president of Realm of Caring in Colorado Springs, Colorado, a nonprofit that focuses on cannabis research and education, senses an interest in CBD within the diabetes community. “In general, especially if they’re not well controlled, people are looking at cannabinoid therapy as an alternative, and usually as an adjunct option,” says Jackson. Callers have questions about CBD for neuropathy pain, joint pain, gastrointestinal issues, and occasionally blood glucose control, according to a spokesperson for Realm of Caring.
