"before smoking took off, the only know cases of lung cancer were pretty much limited to coal miners."
Really??
"Oldest Descriptions of Cancer
Cancer has afflicted humans throughout recorded history. It is no surprise that from the dawn of history doctors have written about cancer. Some of the earliest evidence of cancer is found among fossilized bone tumors, human mummies in ancient Egypt, and ancient manuscripts. Bone remains of mummies have revealed growths suggestive of the bone cancer, osteosarcoma. In other cases, bony skull destruction as seen in cancer of the head and neck has been found.
Our oldest description of cancer (although the term cancer was not used) was discovered in Egypt and dates back to approximately 1600 B.C. The Edwin Smith Papyrus, or writing, describes 8 cases of tumors or ulcers of the breast that were treated by cauterization, with a tool called "the fire drill." The writing says about the disease, "There is no treatment."

Yeah really, I was talking lung cancer as your own quote of me shows and you posted back something totally different.
Yeah really!!!! There is no **historic reference** to lung cancer in that article at all you linked. The ONLY reference is to how a lung cancer is different from another cancer, which has nothing to do with what I said.
Thanks for trying, but consider reading what I post first and then go so far as to even read the article you are linking to me.
In a way, your post may have just made a major statement about cannabis though, thanks.
