I think you mean 'nitrogen triiodide'. That's actually pretty harmless; it mostly crackles, and the biggest danger is getting an iodine burn from it. TATP is just stable enough to use as a terrorist explosive, but unstable enough only a suicide bomber would risk it. And you can make pounds of it from stuff you can buy in a hardware store. Much of the lore about it is crap, BTW, including about half of what's on the Wikipedia page.
We handle it in 200 mg quantities, tops.
