One would think that this hypothesis could be easily checked out via animal studies: treat two groups of rats with the same amount of nicotine and then stop giving one group nicotine and see if there is any increase in cancer onset in that group. Of course, this won't verify David Warren's hypothesis of cave cooking for 5000 years producing biological mechanisms that cause cancer during suddent cessation of smoking.
A friend sent me the link to this article and asked me to take a look at it.
This research (as any other research) will stand or fall based on its merits i.e., whether others are able to replicate it or not. The following comments by gisurgeon are certainly noteworthy:
the above study by kumar-incidentally my friend for close to 30 years-is totally anecdotal-people who have smoked for 30 years -and i am one of them have already damaged their lungs and set in an irreversible chain of events-as doctors blogging on a laymans channel-i do feel we must be more careful about scientific conclusions-i heard this paper is being considered for the ignobel award-a befitting award-

As for David Warren, he doesn't sound like someone whose views can be taken seriously at all. To wit:
1. The "evolutionary argument" that he proposes [man's cooking in caves has resulted in a "biological mechanism (that) protects smokers" against nicotine and tar] seems to be wild speculation -- I guess anybody can propose "evolutionary arguments."
2. Warren is not only an "evolutionary theorist" but also is a "medical hypothesist":
> my own medical hypothesis, based on my own anecdotal evidence. Several deceased friends and family, starting with my paternal grandfather, perished shortly after they quit smoking -- not only from lung cancer, but from other causes ranging from previously-undiagnosed heart disease to industrial accident.
Now that is certainly cause for concern if industrial accidents result from sudden cessation of smoking.
3. > in the good old days, people instinctively understood things like that, without the need for medical research
This scarely needs comments.
4. > while, in astronomy, I remain convinced that the earth revolves around the sun, I would not put all my money even on that proposition, but, given attractively long odds, reserve a penny bet on the sun going round the earth.
Ditto.
Pavan,
Enjoyed this article.
This deserves better attention than it has received. If you had somehow sneaked in references to Ram-Sethu for instance, it would have garnered thousands of hits.
Most Indians (including myself) lack do-it-yourself/tinkering skills. It was a good thing that you played around with wiring a room.

> Anecdotal? I don't think so...number of patients is too huge for that...don't you think so?
It was gisurgeon who said that the paper was anecdotal.
