This has upset me for years. I work in powerplants. To clean the coal tubes in powerplants, they use Saccharine, they do not let us in the same room they store the saccharine in, without an oxegen supplying resperator. But it is fine to drink in your coffee. I talked to a health dept. employee friend of mine, and they checked and said it was fine, because the sacchrine for your coffee is only a 4% strength. Glad i dont drink it.
