Botulin is the most poisonous substance known to humans, with a lethal dose of only 1-2 nanograms per kilogram of body weight. It is produced by the bacterium Clostridium botulinum and causes botulism, a deadly disease that can lead to respiratory failure and paralysis. Strychnine and nicotine are also highly toxic, but they are not as lethal as botulin. Coniine is a toxic alkaloid found in hemlock, but it is not as poisonous as the other three substances.
