A long-term study tracking just over a thousand participants has found regular cannabis smoking can change the function of your lungs as you age.
Over adulthood, tobacco smoking is associated with a progressive decline in how much air you can force from your lungs in a given amount of time.
To this day, there is limited research on the lung effects of smoking cannabis.
The participants included in the current study from New Zealand were no exception.
While it’s easy to measure how many cigarettes a day a person smokes, however, there is currently no standardized form of a joint.
These associations were especially strong and consistent among those who smoke both tobacco and cannabis.
Cannabis has many upsides, but it also has some downsides.
