Does it cause cancer like the other ones do?
;)
Sugar has 16 times greater risk of promoting cancer than saccharine, but the law was written such that sugar was regarded as a "natural" substance while saccharine was man made, and therefore had to be regulated.
Always exercise caution with new items-- it may take 10 or more years to find out what the problems are. Good example, aspartame caused fainting or even seizures after it was released.
Technology is our friend, but it's up to us to take care of ourselves :)
Yes, but don't worry, you wont know about that for another 15-20 years.
