Dwight T Janerich was the Yale academic who designed and implemented the study of spousal and workplace smoking (using NCI data) which was used by one of his PhD students to create the Varela Study. After the premature death of Varela, the tobacco industry seized on this sub-study (used in Varela's PhD thesis) as evidence supporting their claim that there was no linkage between second-hand smoke and lung-cancer in non-smokers.
Janerich re-interpreted the study using all his available data (not just Varela's) and showed that there was a link.
The Varela Study was one of the tobacco industry's main defensive weapons to counter the EPA's ETS Risk Assessment.
