Hello,

Welcome to icliniq.com.

I can understand your concern.

It is highly advisable to quit smoking since it is the leading cause of global lung cancer. Continuing smoking can significantly impact survival rates if lung cancer develops.

Below are some tips to help quit smoking:

  1. Nicotine replacement therapy: Consider nicotine replacement therapy options such as nicotine patches, gum, lozenges (available over the counter), or prescription nicotine in nasal sprays or inhalers. Non-nicotine prescription drugs like Bupropion or Varenicline can also be discussed with a healthcare provider.

  2. Delay technique: When feeling the urge to smoke, try delaying it by at least 10 minutes. Distract yourself during this time by engaging in activities or going to smoke-free areas. This delay might help overcome the craving.

  3. Chew on it: To resist cravings, occupy your mouth by chewing sugarless gum, hard candy, raw carrots, nuts, or sunflower seeds. Something crunchy or tasty can help distract from the urge to smoke.

While electronic cigarettes (e-cigarettes) have gained attention, their safety and effectiveness compared to nicotine replacement medications are not yet established in helping individuals quit smoking.

Kindly consult a specialist, talk to them, and take the medications with their consent.

I hope this information will help you.

Thank you.
