A molecular model of cocaine (C17H21NO4), a stimulant and appetite suppressant drug, obtained from coca plant leaves, which produces low doses of anesthesia. Cocaine's properties allow it to pass through the blood-brain barrier more easily than other psychoactive chemicals. The drug's addictive nature makes more dangerous than other stimulants, as higher doses can lead to sudden cardiac death. Atoms are colored dark gray (carbon), light gray (hydrogen), red (oxygen), and blue (nitrogen).
