Toronto, Canada: Subjects who regularly inhale cannabis smoke possess no greater risk of contracting lung cancer than do those who consume it occasionally or not at all, according to data published online ahead of print in the International Journal of Cancer.
An international team of investigators from Canada, New Zealand, Great Britian, and the United States analyzed data from six case-control studies involving over 5,000 subjects (2,159 cases and 2,985 controls) from around the world.
Authors concluded, "Results from our pooled analyses provide little evidence for an increased risk of lung cancer among habitual or long-term cannabis smokers."
