Mark Twain said, “Quitting smoking is easy. I’ve done it a thousand times.” Maybe you’ve tried to quit as well with little success. Why is it difficult for so many people to stop smoking and stay away from the negative effects of smoking? The answer is nicotine.
Nicotine is a drug found naturally in tobacco, and is as addictive as heroin or cocaine. Over time, a person becomes physically dependent on and emotionally addicted to nicotine, making it harder to stop. The physical dependence causes unpleasant withdrawal symptoms when you try to quit smoking. The emotional and mental dependence (addiction) make it hard to stay away from nicotine after you quit. Studies show that smokers must deal with both the physical and mental dependence to quit and stay quit.
