Health Risks

Does CBD oil have any health risks?

The majority of CBD oil users don’t experience any negative effects.

‘In doses used as a food supplement, CBD poses few risks, and side effects are unusual but can include a dry mouth or drowsiness,’ reveals Dr Brewer. ‘Higher doses used medically are well tolerated, and there are no serious safety concerns. A World Health Organization report issued in 2017 concluded that cannabidiol does not appear to have abuse potential or cause harm.’

However, CBD oil could interact with common prescription medications, so it’s important you always seek the advice of your GP before giving it a go.

‘If you have a health condition, or are taking any prescribed or over-the-counter medicines, always check with your doctor or a pharmacist for possible drug supplement interactions before taking CBD,’ says Dr Brewer. ‘This is because CBD interacts with enzymes involved in metabolising some medicines and may result in increased drug levels that could cause side effects.

The majority of CBD oil users don’t experience any negative effects.

‘If the Patient Information Leaflet that comes with your medication says to avoid grapefruit juice, for instance, then do not take CBD, as the same type of interaction can affect circulating blood levels of your medicine. Even if the leaflet does not mention grapefruit juice, you should still check with your doctor before taking CBD. You should also not take CBD if you are pregnant or breastfeeding.’
