Marijuana worsens COPD symptoms in current cigarette smokers

ATS 2007, SAN FRANCISCOMarijuana worsens breathing problems in current smokers with chronic obstructive pulmonary disease (COPD), according to a study presented at the American Thoracic Society 2007 International Conference, on Tuesday, May 22.

A majority of cigarette smokers in the study were also marijuana smokers. In both younger and older adults in the study, 30% smoked both cigarettes and marijuana. Among younger cigarette smokers, 76% also smoked marijuana, while 58% of older cigarette smokers also smoked marijuana.

The findings come from a study of 648 adults ages 18 and older who answered questions on smoking, including their cigarette and marijuana use, and respiratory symptoms. Study subjects ages 40 and older had lung function tests.
