A new study has linked daily marijuana use to a 44 per cent higher risk of asthma and increased likelihood of chronic obstructive pulmonary disease (COPD).
Daily marijuana use has been linked to a 44 per cent higher risk of asthma, according to a new study published in the Journal of General Internal Medicine.
The study, conducted by researchers at the University of California, San Francisco, also found a 27 per cent increased likelihood of chronic obstructive pulmonary disease (COPD) from cannabis inhalation, though this was not statistically significant.
“Inhaling” was defined to include smoking, vaping, and dabbing. For non-smokers of tobacco, daily marijuana use was associated with a 51 per cent higher likelihood of developing asthma.
The study analysed data from 380,000 adults, including 222,000 who had never smoked cigarettes, making it the largest yet on cannabis inhalation and lung health.
Alison Rustagi, MD, PhD, lead author of the study, said: “If people are looking to reduce their likelihood of developing a chronic lung disease, they should not start using cannabis. And if they already smoke cannabis, they should do it less often.”
