For as long as I can remember, the American cancer society has waged a battle over smoking cigarettes.
They have spent millions on ads stating the consequences of smoking, including "second hand smoke".
I have yet to see them come out with even one word about smoking marijuana.
Why is this.
Smoke in the lungs is very often a killer, and it boggles my mind why they have not come out against marijuana.
Anyone have an idea as to why the ACS is so silent on this issue?
There is no good evidence that smoking marijuana causes cancer, and therefore no reason for the American Cancer Society to wage a campaign against it.
Smoke reaching the lungs is smoke, regardless of the source, and causes lung cancer.
Practically every ad put out by the ACS states smoking causes lung cancer, among other diseases.
Marijuana smoking is statistically miniscule compared to the history that tobacco smoking has, and most of it was underground. So there isn't a large cohort of subjects whose medical history is available to be studied. Plus, you smoke one or two marijuana doses per day - as a heavy user. You smoke 20 - 40 cigarettes per day as a heavy user. Apples and oranges.
The one thing I recall marijuana was more dangerous than cigarettes was that it burned at a higher temperature, so traumatic tissue damage in the lungs was more likely with marijuana than cigarettes. But that is the only study I'm aware of concerning the physical risks of smoking marijuana.
I have been smoking it daily for 40+ years, and I am cancer free. So are all my friends that are also long term users. In fact, of all the friends I have lost to cancer, none of them were long term daily users.
This is not an isolated case. There are millions of people like me in this country, and all over the world for that matter. Yet not one documented case of marijuana causing cancer. Here is someone who has smoked it for 50 years:
People who smoke it (even though there are other ways to ingest it) inhale no where near the amount of smoke per day that cigarette smokers inhale (not even close).
There is absolutely no reason to assume that marijuana smoke causes cancer like tobacco smoke does. I am wondering why you automatically assume there is?
Smoke reaching the lungs is smoke, regardless of the source, and causes lung cancer.
Perhaps, but that is not known with any certainty.
