This thread got a renewed lease on life because of a post from somebody in the UK who can't seem to find TEA locally. Although TCS is a good supplier in the US, intercontinental shipping is likely to be impractical (if TCS would even do it; I haven't checked on this detail).

Anything can be dangerous. You can drown in a remarkably small amount of water.
There are various joke Web sites that talk about the dangers of "dihydrogen monoxide" (water by another name, of course). People sometimes take these seriously and make fools of themselves trying to get this "dangerous substance" banned.
