“Marijuana might do more damage to smokers than cigarettes alone,” the Wall Street Journal reports.
A study published Tuesday in the journal Radiology demonstrated higher rates of conditions including emphysema and airway inflammation among people who smoked marijuana than among nonsmokers and people who smoked only tobacco. Nearly half of the 56 marijuana smokers whose chest scans were reviewed for the study had mucus plugging their airways, a condition that was less common among the other 90 participants who didn’t smoke marijuana.
