Study: Habitual Marijuana Smoking Not Associated With Increased Risk Of Lung Cancer

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, the United Kingdom, 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.”

Study: Cannabis Smoking Not Associated With Increased Lung Cancer Risk Or Other Serious Pulmonary Complications

A forthcoming review to be published in journal Annals of the American Thoracic Society reiterates that the ingestion of cannabis smoke poses nominal pulmonary risks compared to those associated with tobacco smoke. It concludes, “In summary, the accumulated weight of evidence implies far lower risks for pulmonary complications of even regular heavy use of marijuana compared to the grave pulmonary consequences of tobacco.”

Study: No Association Between The Cumulative Consumption Of Cannabis Smoke And The Risk Of Lung Cancer

In a recent presentation given at the annual meeting of the American Association of Cancer Research, investigators from the university of California, Los Angeles provided the latest data reaffirming that cannabis consumption is not associated with an elevated risk of lung cancer. “Our pooled results showed no significant association between the intensity, duration, or cumulative consumption of cannabis smoke and the risk of lung cancer overall or in never smokers,” investigators reported.
