following the publication of a study claiming saccharine was dangerous. If memory serves, a human would've had to drink over 1000 saccharine sodas a day for years to have a higher chance of developing bladder cancer. I couldn't help but think if the required dose was so high, saccharine must make it about the safest stuff on Earth. I never drank the stuff before that study came out.

There's a saying in medicine - the dosage makes the poison. Some substances, even ones considered very toxic, have little or no adverse effect in low dosages. Some may even be beneficial up to a point (vitamin A comes to mind). Beyond that point, they become very dangerous and even lethal.
