What's next?
Quitting smoking can be difficult,
especially if you have been smoking for a long time. It may take several tries
before you succeed, but even if you have a strong addiction, it is still
possible to quit. And even if you have smoked for many years, quitting smoking
now can still increase your lifespan and improve the quality of your
life.
The best way to stop smoking is to get help and to follow a
plan. Medicine that reduces cravings for nicotine, such as bupropion (Zyban),
varenicline (Chantix), or nicotine chewing gum, may also be helpful. For more
information about how you can quit smoking, see the topic
Quitting Smoking.
