Early evidence looking into the use of CBD in the treatment of anxiety and depression has found some exciting results – although on very small samples. The first study assessed anxiety links with public speaking; it found a very specific dose of CBD (300mg) showed anti-anxiety effects. The second study was a stand-alone case report of one child with post-traumatic stress disorder (PTSD). It found CBD oil helped the child safely reduce her anxiety and improve sleep.

What is CBD oil used for?
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.

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.
Only one purported use for cannabidiol, to treat epilepsy, has significant scientific evidence supporting it.
“That’s a problem because THC can increase anxiety. It can actually make seizures worse. Those are the sorts of things you need to be careful about,” Bonn-Miller said.
Meanwhile, a 2017 study led by Bonn-Miller found that nearly 7 of 10 CBD products didn’t contain the amount of marijuana extract promised on the label.
Strong Evidence for Treating Epilepsy
Worse, CBD is being produced without any regulation, resulting in products that vary widely in quality, said Marcel Bonn-Miller, an adjunct assistant professor of psychology in psychiatry at the University of Pennsylvania School of Medicine.
