This is a new to me. Obviously I'm not reading the right journals :-)
But, how much of this is evidence based medicine (EBM).
Take some recent scares, dealt with rather badly I thought on the recent
Medi-Cassete:
Chloramphenicol eye preparations and aplastic anaemia - how many cases have been
reported in the last 40years?
Coal tar scalp/skin preparations and bladder cancers - how many cases have been
reported in the last 40years?
Etc.
How many cases of lung cancer have been reported in the last forty years to
smoking.
Etc
QED.
