Cannabis könnte Lungenkrebsrisiko senken.

Der “New Yorker” berichtet über einige Drogen-Horrorgeschichten. In diesem Zusammenhang wird eine interessante Studie erwähnt, durchgeführt von Doktor Donald Tashkin.

Diese Studie beschäftigte sich mit dem Zusammenhang von Lungenkrebs und Cannabiskonsum. Kurz zusammengefasst:

“Tashkin and his colleagues at U.C.L.A. conducted a major study in which they measured the lung function of various cohorts for eight years and found that tobacco-only smokers had an accelerated rate of decline, but marijuana smokers—even if they smoked tobacco as well—experienced the same rate of decline as non-smokers. “The more tobacco smoked, the greater the rate of decline,” said Tashkin. “In contrast, no matter how much marijuana was smoked, the rate of decline was similar to normal.””

Übersetzt: Dr. Tashkin und seine Kollegen führten über 8 Jahre eine Studie durch, in welcher Sie die Lungenfunktion maßen.  Die Lungenfunktion liess bei nur-Tabakrauchern in beschleunigtem Maße nach, während bei Cannabisrauchern - selbst, wenn diese auch Tabak rauchten - die Lungenfunktion wie bei Nichtrauchern nachliess. Je mehr Tabak, desto schädlicher - im Gegensatz dazu hätte die Menge konsumierten Cannabis’ keine Rolle gespielt.

Okay, soweit so gut; bevor aber nun jeder zum Joint greift, erstmal etwas zum Nachdenken.

Auf der anderen Seite vom grossen Teich rauchen die Leute ihr Cannabis meistens pur, während hier in Deutschland mindestens zur Hälfte Tabak beigemischt wird. Tabak enthält in der Regel viele Additive, die vermutlich krebserregender sind als der Tabak alleine. Interessant wäre auch, wie diese Cannabiskonsumenten ihr Zeug rauchen - im Joint, per Wasserpfeife oder Verdampfer?.

Nun, wenigstens wissen wir jetzt dass Cannabis der Lunge weniger schadet als kommerzieller Tabak - ohne die Konsumform näher zu kennen, würde ich mich auf den Schutzeffekt nicht verlassen…

Cannabis *might* lower risk of lung cancer

The New Yorker reports about some drug stories. In that context they also mention Dr Donald Tashkin of U.C.L.A., who conducted an interesting study about the influence of Cannabis (aka marihuana) on lung cancer.

“Tashkin and his colleagues at U.C.L.A. conducted a major study in which they measured the lung function of various cohorts for eight years and found that tobacco-only smokers had an accelerated rate of decline, but marijuana smokers—even if they smoked tobacco as well—experienced the same rate of decline as non-smokers. “The more tobacco smoked, the greater the rate of decline,” said Tashkin. “In contrast, no matter how much marijuana was smoked, the rate of decline was similar to normal.” Tashkin concluded that his and other studies “do not support the concept that regular smoking of marijuana leads to COPD [Chronic Obstructive Pulmonary Disease].””

OK, sounds fine so far. But before you light up another one, i’ve got some things for you to consider first.

In the USA, most people smoke their cannabis pure, while at least from my experience here in germany joints consist at least half of tobacco. Furthermore, toacco contains a lot of additives which are propably more carcinogen then the tobacco alone. Also, it would be interesting to know which way those cannabis smokers consumed their stuff - in a joint, with a bong, or even with a vaporizer?

Well, at least now we know that cannabis has a less negative impact on our lung than commercial tobacco has - but without knowing the way those guys in the study smoked their cannabis, i wouldn’t expect it to protect me from lung cancer for sure…
