Smoking involves inhaling and absorbing nicotine into the body. Nicotine is a poisonous, addictive chemical found in tobacco.

What is going on in the body?

In the 1960s, medical research began to show that cigarette smoking was quite bad for a person's health. At least 70% of smokers in the United States have made at least one attempt to quit smoking. The nicotine in tobacco is as addictive as cocaine. It is because of this addiction that smoking cessation can be so difficult.

What are the causes and risks of the condition?

People quickly become dependent on nicotine when using tobacco products. Anyone who uses these substances is at risk of experiencing withdrawal symptoms. A trigger is anything that creates an impulse to use tobacco. Triggers can be feelings, such as stress, anxiety, depression, or boredom. They can be visual, such as a picture of a poised glamorous movie star taking a long, seemingly satisfying drag. Triggers can even be certain times of the day, such as work breaks or meals.
