Work places and elite level sports sometimes test for drugs. When testing for cannabinoids they are generally looking for THC which can impair the ability to function and is illegal in the UK to consume without a Medical Prescriptions.
CBD is a legal substance in the UK (please check local regulations if taking into other countries) so is generally accepted in the work place. If you are an elite athlete and competing then the best advice is to contact your governing body to check their stance with CBD.
The statement below is taken from a UK based drug testing service, please note that TAO CBD products do not contain any detectable amounts of THC so will not put you at any risk of failing a drug test.
“Cannabidiol, otherwise known as CBD, is a compound found in cannabis known as a cannabinoid. The most well-known cannabinoid is THC. This is the compound responsible for the ‘high’ associated with cannabis. If you consume CBD oil, you should not test positive for cannabis on a workplace drug test.”
If you are concerned about drug testing then purchase from a reliable producer like TAO CBD who have formulated their products for the UK market and stay away from homemade and “full spectrum” products.
