A new study suggests that smoking cannabis doesn’t carry the same health risks as smoking tobacco

Researchers from the COPD Foundation studied three different groups of participants who either currently, formerly or never smoked cannabis to observe long-term effects on the development of chronic obstructive pulmonary disease.

“Among…participants with or without COPD, neither former nor current marijuana smoking of any lifetime amount was associated with evidence of COPD progression or its development,” the researcher wrote. “Because of our study's limitations, these findings underscore the need for further studies to better understand longer term effects of marijuana smoking in COPD.”
