CBD, a chemical found in cannabis, is a popular ingredient used from beauty products to treatments for chronic pain.
A look at the internet reveals CBD oil, capsules, lip balm, dog meat, shampoo and mascara.
But is it more than a trend? The actual scientific evidence for the effectiveness of CBD are a bit thin, say experts.
The following should be known about CBD.
What is CBD?
CBD, or cannabidiol, is one of the active chemicals in cannabis that is naturally produced by the plant. The other important cannabinoid is THC (tetrahydrocannabinol).
THC is known for its psychoactive properties, said Joey Ton, a trained pharmacist working for the PEER group at the University of Alberta, which focuses on evidence-based medicine.
CBD has some of the same properties as THC, but does not have the same intoxicating effect.
CLOCK: Sativa or Indica? THC or CBD? Canadians can legally buy cannabis, but how do you choose dozens of different types?
"What they believe CBD offers the benefits without the psychoactive effects that THC has," said Ton.
"CBD does not upset people," said MJ Milloy, professor of canopy growth in cannabis at the University of British Columbia.
CBD actually helps combat the psychoactive effect of THC, he said.
At the moment, as a component of cannabis CBD is legal to sell in various preparations such as CBD-hard-dried cannabis, oils and capsules, but currently not in food such as sweets or drinks. CBD-infused beauty products are not legal, according to a Health Canada spokesperson in Canada, though they appear to be very popular in the US.
What is CBD used for?
Depending on who you ask, it seems CBD is good for everything. "In some corners of the Internet, it seems like a panacea," said Milloy. In particular, products containing CBD are generally used to treat pain, addictions, and neurological conditions. Individual reports and preclinical studies have shown that it has pain relief benefits and anti-inflammatory properties.
Does it work?
There are many anecdote proofs. However, anecdotes are generally insufficient to prove their effectiveness.
"Certain clinical studies have shown that CBD is an effective treatment for these seizure disorders," said Milloy.
"For everything else, I have no evidence from clinical trials that would support human use. "
Sound that made a systematic review of the evidence for the medical use of cannabinoids says the same There are good clinical trials that support the use of CBD in certain seizure disorders, but not much else.
. He said, people who claim other effects: "What they cite most often are perhaps non-clinical studies or studies that are not of high quality for their claims."
As a cannabis researcher, Milloy is excited to explore the possibilities of CBD and build science to support its medical and therapeutic use. "I think that the traditions and understanding of cannabis that have evolved over the years are of tremendous value," he said.
"I think it is now our job as scientists to have the highest, best quality approaches so that we can truly find out what is true, what is proven and what is not."
