What is Smoking Cessation?

Smoking cessation refers to the process of discontinuing tobacco smoking. It’s a challenging journey due to the addictive nature of nicotine, but with support, many can overcome this habit. Quitting reduces the risks of numerous health issues, from respiratory problems to cardiovascular diseases, ultimately leading to improved overall health and increased lifespan.

Nicotine Replacement Therapy

Nicotine replacement therapy (NRT) is a medically-approved approach to help people quit smoking. It provides the body with controlled doses of nicotine, without the harmful chemicals found in cigarettes.

The aim is to alleviate withdrawal symptoms and cravings by gradually reducing the nicotine dosage over time. When used as directed, NRT can significantly increase the chances of successfully quitting smoking.


Nicotine replacement therapy (NRT) is available in various forms to cater to individual preferences and needs.

The primary types of NRT include:

  • Nicorette Gum: This is a form of chewing gum that releases nicotine into the bloodstream through the lining of the mouth. It helps to reduce the intensity of cravings and withdrawal symptoms. Users gradually decrease the number of pieces they chew daily until they no longer need it.
  • Nicotrol Inhaler: This device allows the user to inhale a vaporized form of nicotine through the mouth, mimicking the hand-to-mouth action of smoking. It delivers nicotine through the lining of the mouth and throat rather than the lungs.
  • Nicotine Transdermal Patches: These are adhesive patches applied to the skin which release a steady, controlled amount of nicotine throughout the day. They come in different strengths, allowing the user to reduce the dose gradually over time.
  • Nicotine Nasal Spray: Administered through the nose, this spray delivers nicotine directly to the nasal membrane, providing rapid relief from cravings. It’s prescribed for those who require immediate nicotine release.
  • Prescription Medications: There are certain medications not based on nicotine that help with smoking cessation. Bupropion (Zyban) is an atypical antidepressant that reduces withdrawal symptoms and cravings. It doubles the chances of quitting successfully. Varenicline (Chantix) is a medication that works by reducing cravings and withdrawal symptoms. It also diminishes the pleasure derived from smoking, making relapse less rewarding.
  • Behavioral Counseling: This involves working with trained counselors or therapists to identify triggers and develop coping strategies. It aims to address the psychological aspect of the addiction, providing smokers with skills and tools to manage cravings, stress, and potential relapse situations. Combining behavioral counseling with NRT can significantly increase the chances of quitting successfully.

Note: Each type has its own advantages, and the best choice often depends on the individual’s smoking habits, preferences, and any underlying health conditions. It’s essential to consult with a healthcare professional before starting any form of NRT to ensure its appropriateness and effectiveness for the individual.

How to Calculate Pack-Years for Smokers

Pack-years is a term used to measure the cumulative exposure a person has had to cigarettes over time.

It’s a simple calculation that provides valuable information for healthcare professionals when assessing risks for diseases like lung cancer or COPD.

Here’s how to calculate pack-years:


Pack-years = (Number of packs smoked per day) × (Number of years smoked)


  1. Determine the Number of Cigarettes Smoked Daily: If someone smokes 20 cigarettes (equivalent to 1 pack) a day, then they smoke 1 pack per day. If they smoke 10 cigarettes a day, they smoke 0.5 packs per day, and so on.
  2. Determine the Number of Years: This is simply the duration for which the person has maintained the smoking habit at the rate determined in step 1.
  3. Multiply the Two Figures: Take the number of packs smoked daily (from step 1) and multiply it by the number of years the person has smoked (from step 2).


Suppose a person has smoked 1 pack (20 cigarettes) a day for 20 years.

  1. Number of packs smoked per day = 1 pack/day (since they’re smoking 20 cigarettes or one full pack every day)
  2. Number of years smoked = 20 years
  3. Pack-years = 1 pack/day × 20 years = 20 pack-years

This person has a 20 pack-year smoking history.

Knowing the pack-years can help clinicians assess the risk and make recommendations about screenings or interventions.

If a person’s pack-year history changes (e.g., they smoke more or less over time), the calculation can be adjusted accordingly by segmenting the years and then summing up the results.

What is a Respiratory Therapist’s Role in Smoking Cessation?

A respiratory therapist plays a vital role in smoking cessation, particularly given their expertise in lung health and respiratory care.

Their role encompasses several key areas:

  • Education: RTs educate patients about the adverse effects of smoking on the respiratory system, emphasizing diseases like chronic obstructive pulmonary disease (COPD) and lung cancer. By providing tangible information about how smoking directly harms the lungs, they can motivate patients to consider quitting.
  • Assessment: RTs can assess a smoker’s readiness to quit and determine the level of nicotine addiction. This assessment can help tailor specific cessation strategies for each individual.
  • Recommendation: Based on the assessment, RTs can recommend various smoking cessation aids, including nicotine replacement therapy (NRT) or medications, always ensuring they are appropriate for the patient’s respiratory health.
  • Behavioral Counseling: While it may not be their primary role, some RTs are trained in behavioral counseling techniques to help smokers identify triggers and develop coping strategies.
  • Follow-Up and Support: Once a patient decides to quit, regular follow-ups by RTs can provide much-needed support. These check-ins can help address any challenges, track progress, and adjust strategies as needed.
  • Lung Function Monitoring: RTs can conduct regular lung function tests, like spirometry, to show patients the tangible benefits of quitting over time, such as improved lung capacity and reduced symptoms.
  • Referrals: If a patient needs more specialized help, an RT can refer them to other professionals or support groups dedicated to smoking cessation.

Note: Respiratory therapists provide a unique blend of clinical expertise and patient support in the smoking cessation journey, making them instrumental in guiding smokers toward a healthier, smoke-free life.
