Is strychnine still used in rat poison?
Strychnine is also used as a rodenticide, but is not specific to such unwanted pests and may kill other small animals. In the United States, most baits containing strychnine have been replaced with zinc phosphide baits since 1990. In the European Union, rodenticides with strychnine are forbidden since 2006.
What was strychnine used for?
In the past, strychnine was available in a pill form and was used to treat many human ailments. Today, strychnine is used primarily as a pesticide, particularly to kill rats. Uncommonly, strychnine is found mixed with “street” drugs such as LSD, heroin, and cocaine.
What happens in strychnine poisoning?
The onset of symptoms is 10 to 120 minutes after ingestion. Symptoms include seizures, a “sawhorse” stance, and opisthotonus (rigid extension of all four limbs). Death is usually secondary to respiratory paralysis.
How much strychnine is lethal?
In persons killed by strychnine, the highest concentrations are found in the blood, liver, kidney and stomach wall. The usual fatal dose is 60–100 mg strychnine and is fatal after a period of 1–2 hours, though lethal doses vary depending on the individual.
