'''Nicotine''' is a pyrodlidine alkaloid found in the plants of the Solanacae family, especially the [[tobacco]] plant. Its [[chemical formula]] is C<sub>10</sub>H<sub>14</sub>N<sub>2</sub>. It was first isolated by the German chemists Poiselt and Riemann. When it comes into the body's system it is absorbed into the [[blood]]stream as continine, which remains in the system for 48 to 96 hours. Nicotine has been shown to be more addictive than [[cocaine]] and even [[heroin]]. Nicotine is used medicinally to treat ulcerative colitis, [[breast cancer]] among women with the high risk BRCA gene, Kaposi's sarcoma, schizophrenia, and asthma. Nicotine is also used to treat headaches.
