Nearly ANYTHING is bad for you if given in large enough quantities...
It is worth noting that ASPIRIN could not get approval under current
FDA standards (which have killed far more people than have been saved by them)
OTOH, Thalidomide, (which has positive beneficial medical applications in patients OTHER than women of childbearing age BTW) cited as the FDA 'poster child' justification for our current US drug over-regulation, would probably have PASSED the initial approval tests depending on just which variety of lab rodent the tests were run on. I forget the exact details, but there was one standard critter type that had no negative impact, one that had human style birth defects, and one where it was lethal. In actual historical record, Thalidomide was pulled by it's manufacturer as soon as the problem was identified, not by any government agency.
It is worth noting that AFAIK, the cyclamate cancer studies that got it banned initially haven't been successfully duplicated, and that actual HUMAN use in most of the world for many years have not shown any significant issues in over 30 years, making cyclamates one of the oldest artificial sweeteners, and giving it one of the best records.
I'm just wondering how difficult it is, and what the best source would be, to get some of them down from Canada. I know there is getting to be a fairly heavy traffic in prescription drugs across the border, but how hard is it to get cyclamates across?
