What is nicotine classified as?

Nicotine is classified as an addictive and toxic substance found specifically in tobacco products. This classification is based on its physiological effects on the body and its potential to lead to dependence. Nicotine acts as a stimulant, interacting with the brain's reward pathways and creating feelings of pleasure. However, its addictive properties contribute to the difficulty many individuals face when trying to quit using tobacco products. Additionally, nicotine can have harmful effects on health, contributing to various diseases and increasing the risk of cardiovascular issues, making it toxic when consumed in certain quantities.

Understanding this classification is crucial in discussions surrounding smoking cessation programs and public health policies, as recognizing nicotine's addictive nature helps underscore the challenges associated with tobacco dependence.
