Topical tobacco paste is sometimes recommended as a treatment for wasp, hornet, fire ant, scorpion or bee stings. An amount equivalent to the contents of a cigarette is mashed in a cup with about a 0.5 to 1 teaspoon of water to make a paste that is then applied to the affected area. It is claimed that if applied immediately, complete remission is common within 20–30 minutes. There is no scientific evidence that this home remedy works to relieve pain. For about 2 percent of people, allergic reactions can be life-threatening and require emergency treatment. For more on this, see bee stings.
