In collaboration with our national and international colleagues, we have just updated the lower-risk cannabis use guidelines according to the most recent evidence. Remember that the only way to avoid the harms associated with cannabis is to completely abstain from consuming it. For those who would like to consume it, it is safer to delay initiation of use as late in life as possible. For those who consume it, choosing products with a low THC content and/or high CBD: THC ratios which are administered by other routes than inhalation, reducing the frequency of consumption and refraining from driving a motorized vehicle after using cannabis are behaviours that reduce the risk of harms. Among the changes since 2017, we note the advice to stop or decrease (the intensity, the frequency of) cannabis use in people with cognitive impairments in order to improve their cognitive performances and to use legal cannabis products and/or devices that are quality controlled.
