This report also turned out to be almost entirely bogus. Shockingly, "air flow" was the only category (of several) in which marijuana was determined to be more harmful. Researchers stated that marijuana was 2.5 to 5 times more harmful than tobacco in this category, which reporters simply rounded up to 5 for the headline (behold the lofty journalistic standards of Reuters). Reporters also failed to mention conclusive research proving that marijuana does not cause lung cancer; a notable omission since "bad for your lungs" likely implies cancer for many readers. Finally, media reports failed to explain that marijuana users consume far less per day, and do not continue using for nearly as many years as tobacco smokers.
