the MPR take:

A case study in the American Journal of Psychiatry reports on a 24-year-old man with a depressive disorder and a sexual identity disorder who attempted suicide via consuming liquid nicotine. The man attempted to poison himself by ingesting one capsule of liquid nicotine (used in electronic cigarettes) containing 180mg of nicotine. The patient requested an ambulance immediately after consuming the capsule and was given 3,000mg p.o. of charcoal. Although this is the first reported case of a suicide attempt using liquid nicotine, the authors warn that more cases could be seen because suicide guides on the internet often suggest this as a method of committing suicide.
