I believe you said:
"You two can keep cackling about sources all you like but you cannot change the fact that an interview is not a reliable basis for a study of this sort and you have not even bothered to challenge that."
Then I take a look at the study you provided us with:
To assess the current status of surviving cohort members, in mid-1999 we sent out a two page questionnaire on smoking and lifestyle to those participants with an address for 1995 or later on their driver's licence.
Hmmmmm, seems suspiciously like an interview to me.
