Five key steps to quit smoking:
1. Make the decision to quit smoking and set a date to stop.
2. Get support from family, seek counseling, and join a support group.
3. Change your lifestyle by altering routines, eating and drinking habits, and engaging in relaxation.
4. Consult your doctor about medication to help you quit smoking.
5. Don't get discouraged if you fail initially, as relapse is common in the first three months, so keep trying if you slip up.
