LONDON - Smoking weed is not the harmless recreational activity it may seem because it can cause lung cancer, researchers in England said yesterday.
Regularly smoking three or four joints a week, even for less than six years, can hurt the lungs and rob the body of antioxidants that protect cells against heart disease and cancer.
"Smoking cannabis on a regular basis actually depletes your lungs of protective antioxidant substances," said Dr. Sarah Nuttall of the University of Birmingham.
She shared the data at the British Thoracic Society in London.
