The LD 50 of nicotine is 50 mg/kg for rats and 3 mg/kg for mice. 0.5–1.0 mg/kg can be a lethal dosage for adult humans, and 0.1 mg/kg for children.

Nicotine gum is a chewing gum containing a small dose of nicotine polacrilex. [1] It is classified as a short-acting (also called fast-acting) form of NRT because it relieves the cravings and symptoms that occur with smoking cessation more quickly than a long-acting NRT (i.e., the nicotine patch).
