And those "reports" were undoubtedly produced by people or organizations with a particular agenda. This topic comes up regularly, and while I am NOT in favor of smoking on airplanes, I do prefer to deal in facts rather than spin/speculation/innuendo etc.

The cause of the fires in both of the accidents cited was never established; a discarded cigarette could not be ruled out neither could it be definitively shown to have been the source. If you read the AC797 report thoroughly you may find that the scenario for a cigarette starting the fire is so contrived as to be virtually impossible.

There have been other unexplained in-flight fires which could conceivably have involved a cigarette, but this has never been proven.
To reiterate, no airline crash has ever been shown to be as the result of smoking in the cabin. Not one.
