Cannabis Smoking Not Associated with Increased Lung Cancer
Posted by Marijuana Doctors on 06/24/2013 in Medical Marijuana Research
A upcoming research article to be published in the Annals of the American Thoracic Society explains that the ingestion of cannabis smoke does not pose increased risks of pulmonary complications when compared to tobacco smoke. The author of research study is Donald P Tashkin, MD, an emeritus professor of medicine and medical director of the Pulmonary Function Laboratory at the David Geffen School of Medicine at University of California. Donald P Taskin, a federal government sponsored researcher has been studying marijuana and lung function for more than 30 years.
A preview of Dr. Taskins reviews appears on the American Thoracic Society news website. It reads:
Dr. Tashkin found that regular smoking of marijuana by itself causes visible and microscopic injury to the large airways that is consistently associated with an increased likelihood of symptoms of chronic bronchitis that subside after cessation of use. He also found that the evidence does not indicate that habitual use of marijuana leads to significant abnormalities in lung function when assessed either cross-sectionally or longitudinally, except for possible increases in lung volumes and modest increases in airway resistance of unclear clinical significance.
The author finds no clear link between marijuana use and the development of COPD or lower respiratory tract infections. In addition, “findings from a limited number of well-designed epidemiological studies do not suggest an increased risk for the development of either lung or upper airway cancer from light or moderate use, although evidence is mixed concerning possible carcinogenic risks of heavy, long-term use,” Dr. Tashkin notes. “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.”
The full paper will be available this month.
Although light and moderate ingestion of cannabis smoke poses nominal risks and does not suggest increased risks for development of lung or upper airway cancer, the evidence concerning heavy use is mixed. Dr. Taskin notes that the research of heavy use and possible carcinogenic risks has yet to be fully determined.
In this case, if you are a medical patient that medicates on a daily basis, it may be best advised to consider other means of cannabis ingestion. This includes Vaporization, Edibles, Raw Jucing and Tinctures.
