It is recommended that you can quit smoking abruptly.
Smoking kills 4 million people in the world every year and mainly causes digestive, respiratory, cardiovascular diseases and various cancers. The earlier you quit smoking, the lower the impact on your body, so quitting smoking suddenly is not harmful to your body, but you may experience withdrawal symptoms, such as poor sleep quality, anxiety and other discomforts. However, these symptoms will gradually decrease and disappear after 2 weeks.
Of course, it is best to quit smoking slowly and gradually, so that the body can effectively relieve the discomfort.
If you experience withdrawal symptoms or feel unwell after quitting smoking, you can go to a smoking cessation clinic in a hospital to help you quit smoking through behavioral and cognitive changes and medication.
Behavioral and cognitive modification methods include stimulus control and relaxation training. Medication includes nicotine replacement, bupropion extended-release, and varenicline. The two work better together. Medications should be used under a doctor’s supervision.
