A small number of patients in the UK may be prescribed a cannabis-based medicine to treat epilepsy or nausea during chemotherapy. Visit the NHS website for more information on medical cannabis.
A systematic review looking at the use of CBD for epilepsy concluded that there is insufficient evidence to support the efficacy and long-term safety of using it to treat epilepsy. It does, however, suggest, albeit in very low numbers, that small daily doses were safe in a small group of adults for a short period of time.
If you're considering using CBD oil, you should speak to your GP or other healthcare professional to ensure that it is safe and appropriate for you to do so.
Can I buy CBD oil safely?
One study reported reduced pain and muscle spasms in people with multiple sclerosis.
For all the above uses of CBD, more human studies are needed to draw conclusive results.
Most large health food stores will stock 'pure' CBD oil. However, as it is classed as a 'food supplement' rather than a 'medicinal product', it isn't regulated in the UK. This means you cannot know for sure that the product you buy contains the 'active' ingredients at the amounts listed on the label. Furthermore, the product may contain contaminants such as pesticides, heavy metals and other elements. For this reason, the NHS highlights there is no guarantee that these products will be of good quality or provide the intended health benefits.
What is CBD oil?
Contrary to popular belief, CBD oil is legal in the UK as it is not a controlled substance. There are, however, strict restrictions over its THC content. CBD oil that isn't medically prescribed can only have a maximum THC content of 0.2%. CBD oil products that have a higher THC content may be available to buy online, but not legally.
CBD oil is increasingly popular, both as a food supplement and as an oil to apply topically to the skin. We asked a dietitian to explain what it is, why people use it and whether it's safe.
There are also CBD capsules, CBD gummies, and under-the-tongue CBD sprays.
What Is CBD Oil Used For?
For the study, 57 men took either CBD oil or a placebo (sugar pill) before a public-speaking event. The researchers based anxiety levels on measures like blood pressure and heart rate. They also used a fairly reliable test for mood states called the Visual Analog Mood Scale (VAMS).
High Blood Pressure
Unlike the THC that's in marijuana, CBD oil doesn't get you high. It contains a chemical called cannabidiol that might help relieve stress, anxiety, drug withdrawals, and nerve pain.
