Very high doses of medical cannabis have no effect on driving, according to a new study. Researchers in Australia found that 1,500mgs of cannabidiol (CBD) - the highest daily medicinal dose available there - has "no impact" on people’s driving or cognitive abilities.
CBD is a component of cannabis that many people around the world use to improve their sleep and energy levels. It is often consumed orally, in oil form, but it can also come in gummy bears, chocolate and even beer.
In the UK it is classified as a food supplement as it is illegal to market the substance as a health product and is not available on the NHS. Many countries, including the UK, do allow people to drive on CBD as it is not psychoactive and contains less than 0.1% THC which is the substance that gets people high when they smoke cannabis.
