LD<sub>50</sub>s are usually measured in g/kg, as the amount of toxin to kill something is usually linearly related with its mass. The lower the LD<sub>50</sub>, the more lethal the toxin. An LD<sub>50</sub> can be determined for almost any substance: for example, the LD<sub>50</sub> for sugar (in rats) is 29.7 g/kg. However, {{w|Botulinum}} toxin (commercially known as Botox in the beauty industry), the most acutely toxic substance known, has a LD<sub>50</sub> of roughly 1 ng/kg, or 0.000000001 g/kg, a vanishingly small amount. |

The worldwide average weight of an adult is 62 kg (137 lb), so the lethal dose would be 124 kg (273 pounds) of toxicology papers. Death is apparently caused by compression or smothering. |

A third method of delivering a toxin is by {{w|Subcutaneous injection|subcutaneous injections}} which are highly effective in administering vaccines and medications, but that number is omitted since they couldn't figure out how to do it (if they could, the amount of paper required to trigger a fatal blood vessel blockage would probably be fairly small). |
