What is tobacco?
Cigarettes and Chewing Tobacco
Tobacco is an agricultural crop that is used to make cigarettes. It is grown all over the world and supports a billion-dollar industry. Tobacco is dried and processed, then either placed into cigarettes and processed, or manufactured for chewing tobacco. The psychoactive ingredient is nicotine, a stimulant, but more than 4,000 other chemicals (2,000 of which are known to be poisonous) are present in cigarettes.
Tobacco is a nervous system stimulant that triggers complex biochemical and neurotransmitter disruptions. It elevates heart rate and blood pressure, constricts blood vessels, irritates lung tissue, and diminishes your ability to taste and smell.
