DEC 01, DEC 07, There's a history - usually dated back to World War II - of spies carrying suicide pills, just in case they were captured.
These were reportedly called L-pills L for Lethal. The Encyclopedia of Espionage cites the case of a CIA mole in the Soviet Union, who eluded prison or worse by biting the cyanide loaded tip of a fountain pen.
If I'm following the Skyfall story right, though, the fictional spies of the British spy used the old fashioned cyanide-in-a-glass-capsule-hidden-in-a-tooth scenario. The idea was that the spy could crunch down if needed; if the capsule worked loose and was accidentally swallowed, the glass would contain the poison.
My guess is that this would be usually sodium or potassium cyanide, mostly because they are the versions usually found in pill or capsule form.
But, in the movie scenario, it's identified as hydrogen cyanide. And according to the script, it's not lethal but corrosive.
So - since my son wouldn't put up with me doing it - let's pick that apart here. Although hydrogen cyanide HCN is best known as a lethal gas it actually has a chemical warfare classification , it can also be found in liquid form, where it is usually referred to as Prussic Acid or hydrocyanic acid.
This is what I suspect the Skyfall scriptwriter grabbed onto when he chose it for his destructive suicide pill. It's worth noting that KCN and NaCN are considered mildly corrosive salts and tend to cause distinctive lesions the intestinal walls.
But, of course, they don't have that "acid" nomenclature. The problem is, though, that the word acid doesn't often equal to "melt your bones. Think of citric acid in fruits like oranges and limes. Antidotes for cyanide poisoning are most useful if given as soon as possible after exposure. Clinicians should treat suspected cases accordingly and not wait for laboratory confirmation.
The most important thing is for victims to seek medical treatment as soon as possible. Skip directly to site content Skip directly to page options Skip directly to A-Z link.

What cyanide is Cyanide is a rapidly acting, potentially deadly chemical that can exist in various forms. Cyanide is also known by the military designations AC for hydrogen cyanide and CK for cyanogen chloride. Where cyanide is found and how it is used Cyanide is released from natural substances in some foods and in certain plants such as cassava, lima beans and almonds.
Pits and seeds of common fruits, such as apricots, apples, and peaches, may have substantial amounts of chemicals which are metabolized to cyanide. The edible parts of these plants contain much lower amounts of these chemicals. Cyanide is contained in cigarette smoke and the combustion products of synthetic materials such as plastics.
Combustion products are substances given off when things burn. In manufacturing, cyanide is used to make paper, textiles, and plastics. It is present in the chemicals used to develop photographs. Cyanide salts are used in metallurgy for electroplating, metal cleaning, and removing gold from its ore.
Cyanide gas is used to exterminate pests and vermin in ships and buildings. If accidentally swallowed, chemicals found in acetonitrile-based products that are used to remove artificial nails can produce cyanide when metabolized by the body. Reports have indicated that during the Iran-Iraq War in the s, hydrogen cyanide gas may have been used along with other chemical agents against the inhabitants of the Kurdish city of Halabja in northern Iraq.
How you could be exposed to cyanide You could be exposed to cyanide by breathing air, drinking water, eating food, or touching soil that contains cyanide. Cyanide enters water, soil, or air as a result of both natural processes and industrial activities. When present in air, it is usually in the form of gaseous hydrogen cyanide. Smoking cigarettes is probably one of the major sources of cyanide exposure for people who do not work in cyanide-related industries.
