badscience.net writes about at a formal review of a smoke associated effect that
found 43 [studies] in total, and overall, smoking significantly increases your risk of Alzheimers … 11 of the studies were written by people with affiliations to the tobacco industry. This wasnâ€™t always declared, so to double check, the researchers searched on the University of Californiaâ€™s Legacy Tobacco Documents Library, a vast collection of scanned material which has been gathered over decades of legal action.
I didn’t know of this collection. Although that topic was never a main scope of my research they collected nearly 300 documents mentioning my name, uhh. Maybe I haven’t been so much in the focus of this industry although I remember a phone call by a headhunter (I declined to work for them). Does that matter?
A lot: the risks of Alzheimers associated with smoking reported by these papers were on average about a third lower than those conducted by other researchers, and they produced many papers showing cigarettes were actively protective.
