What is the most effective method to quit smoking?

Question

Hello doctor,

I am 35 and have been smoking around 10 cigarettes a day for almost eight years. I have tried quitting multiple times, but the cravings come back after a few days. I saw an anti-smoking awareness campaign at my workplace, and it really made me think about quitting seriously this time. My concerns are:

Are nicotine patches or gums actually effective compared to tablets like Varenicline?
Could I undergo a lung function test or scan to see if any early damage has occurred?
Does quitting suddenly (cold turkey) cause anxiety or mood swings?
How can that be managed during the initial phase?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I have gone through your query and completely understand your concern. The good news is that you are still at a stage where stopping smoking now gives you an excellent chance of completely avoiding long-term lung damage.

Nicotine patches and gums are effective tools. Among all available options, Varenicline tablets are usually the most effective single medication.

The next best option is a combination nicotine replacement therapy (NRT), which means using a daily patch for steady nicotine levels, along with a fast-acting form like gum or lozenge for

sudden cravings.

Combination NRT works about as well as Varenicline for many people. Using only one form (like just a patch or just gum) still helps, though it may be slightly less effective. The best choice depends on what you are comfortable using, your medical history, and how well you tolerate each method.

When you stop smoking, it is normal to experience withdrawal symptoms such as anxiety, irritability, poor sleep, or a low mood. These usually peak around days two to three and gradually settle within one to two weeks.

Medications like Varenicline or combination NRT help blunt these symptoms and make the process smoother.

You can also support your progress with a few simple coping steps:

Delay the urge, take deep breaths, sip water, and distract yourself for five minutes when a craving hits.
Avoid alcohol during the first month, remove all smoking cues like lighters and ashtrays, and try to get a bit more sleep.
A 20 to 30-minute daily walk can also reduce cravings and improve your mood.
Brief counseling or a quit-line program roughly doubles your success rate.

So, combining medication with some form of support is strongly recommended.

Since you have been smoking for a while, it is also wise to check your current lung health.

I suggest a spirometry test with a bronchodilator response, and if available, a diffusion capacity test (DLCO).

These can detect early airflow limitations from smoking even before symptoms appear. A chest X-ray may also help to give a general overview, though it would not reveal subtle early changes.

You have made a very important decision for your health, and you are in a good position to succeed.

Please feel free to reach out again if you have more questions or need support during this process.

Thank you.
