Why age can change the picture

Health Canada says adults over 55 may be more sensitive to cannabis because the body's response to substances changes with age. Existing conditions and use of multiple medicines can add uncertainty. Effects vary by person, product, route and other substances; age alone cannot predict an individual's response.
