如何快速改正不良习惯

Smokers may have started smoking because their friends did or because it seemed cool. But they keep on smoking because they became addicted to nicotine, one of the chemicals in cigarettes and smokeless tobacco.

Nicotine is both a stimulant and a depressant. That means it increases the heart rate at first and makes people feel more alert (like caffeine, another stimulant). 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. According to many experts, the nicotine in tobacco is as addictive as cocaine or heroin.

But don't be discouraged; millions of Americans have permanently quit smoking. These strategies can help you quit, too:

Put it in writin
g. People who want to make a change often are more successful when they put it in writing. So write down all the reasons why you want to quit smoking, such as the money you will save or the stamina you'll gain for playing sports. Keep that list where you can see it, and add to it as you think of new reasons.

Get support.
People whose friends and family help them quit are much more likely to succeed. If you don't want to tell your parents or family that you smoke, make sure your friends know, and consider confiding in a counselor or other adult you trust. And if you're having a hard time finding people to support you (if, say, all your friends smoke and none of them is interested in quitting), you might consider joining a support group, either in person or online.
