My mistake. It was indeed "iodide". I'm sure there's a big difference, but I'm not a chemist so I can't tell you what it is. However, we're talking about the treatment sometimes used for exposure to certain types of radioactivity. Whether that happens to be iodide or iodine.

Below is the ad I was speaking of. At the time I saw it, it was first up on the "Portal Page", which is where my browser goes first thing when I hit the ETS forums. So "front page" was probably the incorrect term for me to use too. Despite my mistakes, I think my point regarding advertising of this stuff in the US is still valid, even though I look a little stupid at the moment for using incorrect terminology.
