The difference, of course, is that there were a large number of symtoms,
very statistically significant differences in longevity, etc. with cigarette
smoking. Even with simple studies, it was easy to see.
With DDT, much more sophisticated studies were done. It's impossible to
prove that no-one is hurt by exposore to DDT, Roundup, etc. But, Roundup
has been subjected to the tumor prone mice study. What hasn't, is natural
supplements. It is likely that there are dangerous things sold in health
food stores that we could check for, but by law they are not checked because
they are natural.
