Smokers often start smoking because friends or family do. But they keep smoking because they get addicted to nicotine. Nicotine is both a stimulant and a depressant. That means it increases the heart rate at first and makes people feel more alert. Then it causes depression and fatigue. The depression and fatigue — and the drug withdrawal from nicotine — make people crave another cigarette to perk up again. Some experts think the nicotine in tobacco is as addictive as cocaine or heroin.
