What Are the Effects of Nicotine on the Brain?

Nicotine, commonly known as nicotine, is an alkaloid found in the family Solanaceae (Solanum), an important component of tobacco, and a representative of N-choline receptor agonists. The central nervous system has effects and has no clinical application value.

The name Nicotine comes from the scientific name Nicotiana tabacum of the plant Nicotiana , which is named after Jean Nicot de Villemain, a Frenchman in Portugal.

In 1843, Melsens proposed the chemical formula of nicotine. In 1893, Adolf Pinner discovered the structure of nicotine. In 1904, A. Pictet and Crepieux successfully used the synthetic method to obtain nicotine.

Nicotine is not only found in tobacco leaves, but also in the fruits of many solanaceae plants. For example, plants such as tomatoes and goji berries contain nicotine, and these vegetables and herbs are considered to be healthy foods that are good for the human body. . Because of this, as early as the 1990s, the World Health Organization vigorously promoted "nicotine replacement therapy" worldwide to quit smoking, replacing the nicotine obtained from cigarettes in the past, helping people to physically and psychologically overcome their dependence on cigarettes, so that Chance to quit smoking more than doubles.

In June 2012, American scientists developed a new type of nicotine vaccine that can help smokers quit smoking, while also preventing non-smokers from developing this bad hobby. A single shot of this vaccine can give the recipient a lifelong immune response.
