70% smoked tobacco and 50% dope. But the dope is not correlated?
The entire article is very misleading.
If true it actually says more about the cause of tobacco promoting cancer in that the cause is obviously not known.
If this bears out it is a ajor finding in that it would indicate that they are wrong about what in tobacco causes cancer and the differences between dope smoke and tobacco can be used to perhaps find out what the actual causative agent is.
For example, there could be asbestos in tobacco but not dope.
As much as i like Hank Hill, I gotta hunch it's the propane fumes used as a dehumidifier/drying agent.
That's one major difference! Plus the advertising of propane, makes it sound like the second coming. If they're trying that hard to sell it (propane), there must be a reason!!!!
