1) In the movies when someone ingests cyanide, they keel over fairly quickly. How fast would the antidote have to get to someone to save his life?
2) What would be the most effective way to administer amyl nitrite as an antidote to said cyanide - inhalation? Something else?
3) Amyl nitrite is described as having a "penetrating odour" - what, exactly, does it smell like? How far does ths smell carry - ie, would people across the room be able to smell it, or just people close by? Would the smell linger for any length of time?
4) I'm given to understand that amyl nitrite "poppers" of various brand names are sold in some sex shops. Are they illegal anywhere? Does anyone know of a database with this information? And perhaps most important, is there any reason why poppers wouldn't work as a cyanide antidote in a pinch?
