Understanding What Happens When You Quit Smoking

Before diving into the how-to steps, it helps to understand the remarkable quitting smoking benefits your body experiences. According to the American Lung Association, positive changes begin within minutes of your last cigarette:

  • 20 minutes: Heart rate and blood pressure begin to drop
  • 12 hours: Carbon monoxide levels in your blood return to normal
  • 2 weeks to 3 months: Circulation and lung function begin to improve
  • 1 to 9 months: Coughing and shortness of breath decrease
  • 1 year: Risk of coronary heart disease drops to about half that of a smoker

Your lungs are remarkably resilient organs. The cilia—tiny hair-like structures that help clear mucus and debris—begin regenerating within days of quitting. This is why many ex-smokers experience increased coughing initially; your respiratory system is literally waking back up.

Step 1: Set Your Quit Date and Prepare Your Support System

The first step in any successful smoking cessation journey is choosing a specific quit date. Research published in Addiction journal shows that smokers who set a definitive quit date are significantly more likely to succeed than those who try to "cut back gradually."

Here's how to prepare:

  • Pick a date within the next two weeks—far enough to prepare, close enough to maintain motivation

  • Tell friends, family, and coworkers about your decision

  • Remove all cigarettes, lighters, and ashtrays from your home and car

  • Identify your triggers (stress, alcohol, certain social situations)

  • Download a quit-smoking app to track your progress

Consider joining a support group or online community. The CDC reports that people who use counseling along with other methods have higher success rates. You don't have to do this alone—and having people who understand what you're going through makes the hard days manageable.

Step 2: Address Nicotine Withdrawal Support Naturally

The first few weeks are often the toughest. Nicotine withdrawal can bring irritability, anxiety, difficulty concentrating, and intense cravings. While prescription options exist, many people seek to quit smoking naturally using evidence-based natural approaches.

Natural strategies that support withdrawal:

  • Stay hydrated: Water helps flush nicotine from your system faster and reduces headache intensity
  • Exercise: Even a 10-minute walk can reduce cravings by releasing endorphins and improving mood
  • Deep breathing: When cravings hit, take 10 slow, deep breaths—this activates your parasympathetic nervous system
  • Oral substitutes: Sugar-free gum, carrot sticks, or sunflower seeds can help address the hand-to-mouth habit
  • Herbal support: Certain herbs like American ginseng and valerian have been traditionally used to support calm and reduce stress

A 2022 study in the Journal of Alternative and Complementary Medicine found that participants using natural stress-management techniques alongside their quit plan reported less severe withdrawal symptoms compared to those using willpower alone.

Step 3: Focus on Breathing Support and Respiratory Exercises

Your lungs are relearning how to function without constant smoke exposure. Supporting this process with intentional breathing exercises can make a noticeable difference in how you feel day-to-day.

Try these breathing techniques:

Diaphragmatic Breathing (5 minutes, twice daily)

  1. Sit comfortably or lie flat on your back
  2. Place one hand on your chest and one on your belly
  3. Breathe in slowly through your nose, letting your belly rise
  4. Exhale slowly through pursed lips
  5. Focus on keeping your chest relatively still while your belly moves

Pursed Lip Breathing (Use during shortness of breath)

  1. Relax your neck and shoulders
  2. Inhale through your nose for 2 counts
  3. Pucker your lips like you're blowing out a candle
  4. Exhale slowly for 4 counts
  5. Repeat until breathing feels easier

The Cleveland Clinic recommends these exercises for anyone looking to strengthen respiratory function. Over time, you may notice deeper breaths, better stamina, and less shortness of breath during physical activity.

Step 4: Choose the Right Lung Health Supplements

Supporting ex-smoker lung recovery often includes targeted supplementation. The right lung health supplements can provide your respiratory system with nutrients that support natural healing processes and maintain clear airways.

Key ingredients backed by research:

  • NAC (N-Acetyl L-Cysteine): This amino acid supports glutathione production, your body's master antioxidant. A 2020 review in Respiratory Medicine highlighted NAC's role in supporting healthy mucus consistency and respiratory wellness
  • Mullein Leaf: Used for centuries in traditional herbalism, mullein supports respiratory health and may help soothe irritated tissues. Available as a mullein tincture or mullein gummies for easy daily use
  • Vitamin D: Research shows many smokers and ex-smokers have low vitamin D levels, which plays a role in immune function and respiratory health
  • Elderberry: Contains antioxidants that support immune function during recovery

BetterLungs Capsules combine all of these ingredients in one doctor-formulated supplement: NAC (400mg), Mullein Leaf (300mg), Vitamin D (1000 IU), Maritime Pine Bark Extract, Elderberry, American Ginseng, and Reishi Mushroom. The formula was developed by Dr. Chris Jackson, PharmD, specifically to support lung health and respiratory wellness.

For those who prefer liquids, the BetterLungs Mullein + Chlorophyll Tincture offers fast absorption and has been clinically studied. In a 60-day Citruslabs clinical trial:

  • 81% of participants reported less frequent coughing
  • 77% reported clearer airways
  • 73% reported easier mucus clearance
  • 68% reported improved sleep quality

All Betterbrand products are third-party tested by Eurofins Scientific, made in a GMP-certified facility in the USA, and backed by a 365-day money-back guarantee. You'll find them at CVS, Walgreens, and GNC nationwide.

Step 5: Optimize Your Diet for Ex-Smoker Lung Recovery

What you eat matters more than you might think. Research from the European Respiratory Journal found that certain foods contain compounds that support lung function and provide respiratory support.

Foods that support lung health:

  • Leafy greens: Spinach, kale, and Swiss chard provide chlorophyll and antioxidants
  • Berries: Blueberries, strawberries, and blackberries are rich in anthocyanins, which support healthy inflammatory response
  • Fatty fish: Salmon and mackerel provide omega-3 fatty acids linked to respiratory wellness
  • Tomatoes: High in lycopene, which may support lung tissue health
  • Beets: Contain nitrates that may help improve oxygen efficiency
  • Apples: Studies show regular apple consumption is associated with better lung function

Foods and drinks to limit:

  • Processed foods high in sodium (can contribute to water retention)

  • Excessive dairy (may increase mucus production in some people)

  • Sugary beverages

  • Alcohol (especially in early quitting stages, as it's a common trigger)

Consider incorporating BetterLungs Detox Tea into your routine—a caffeine-free blend of Mullein, Thyme, Rooibos, American Ginseng, Elderberry, and Ginger that provides natural respiratory support and makes for a soothing evening ritual.

Step 6: Create a Smoke-Free Environment

Environmental factors play a bigger role in lung health after quitting than most people realize. Your home should become a sanctuary for your healing respiratory system.

Steps to optimize your environment:

  • Deep clean your home: Smoke residue (thirdhand smoke) clings to fabrics, walls, and carpets. Wash curtains, steam clean carpets, and wipe down walls
  • Improve air quality: Use a HEPA air purifier, especially in bedrooms
  • Add houseplants: Spider plants, peace lilies, and snake plants can help filter indoor air naturally
  • Control humidity: Keep indoor humidity between 30-50% to support comfortable breathing
  • Avoid secondhand smoke: Politely ask smoking friends and family to smoke outside

A 2023 study from the National Institutes of Health found that indoor air quality significantly impacts respiratory recovery outcomes. Investing in your environment is investing in your lungs.

Step 7: Build Sustainable Long-Term Habits

Smoking cessation is a marathon, not a sprint. The natural lung detox process takes time—up to 15 years for your lung cancer risk to approach that of a never-smoker, according to the American Cancer Society. Building sustainable habits ensures you stay on track.

Long-term success strategies:

  • Celebrate milestones: Mark one week, one month, six months, and one year smoke-free
  • Save the money: Put what you would have spent on cigarettes into a visible savings jar or account
  • Stay active: Regular exercise continues to support lung capacity and reduce cravings
  • Maintain supplement routines: Consistent respiratory support becomes part of your wellness lifestyle
  • Plan for triggers: Holidays, stressful events, and social situations require advance planning
  • Be kind to yourself: If you slip, don't give up—most successful quitters try multiple times before succeeding for good

Remember: every smoke-free day is a victory. Your body is healing with each passing hour.

Frequently Asked Questions

How long does it take for lungs to heal after quitting smoking?

Lung healing begins within hours of your last cigarette, but the full recovery timeline varies by individual and smoking history. Most ex-smokers notice improved breathing within 1-9 months as cilia regenerate and inflammation decreases. Lung function continues to improve over years, though some changes from long-term smoking may be permanent. Supporting your respiratory wellness with breathing exercises, proper nutrition, and lung health supplements like BetterLungs can help optimize your body's natural healing process.

What supplements help with quitting smoking?

Several supplements may support the quitting process and lung recovery. NAC (N-Acetyl L-Cysteine) supports healthy mucus clearance and antioxidant production. Mullein leaf has been traditionally used to soothe respiratory tissues and support clear airways. Vitamin D supports immune function, which can be compromised in smokers. American Ginseng may help support stress response during withdrawal. BetterLungs Capsules combine these ingredients in one comprehensive formula formulated by Dr. Chris Jackson, PharmD.

Does mullein actually help lungs?

Mullein (Verbascum thapsus) has been used for respiratory support in traditional herbalism for centuries. Modern research suggests mullein contains compounds that may help soothe respiratory tissues and support natural mucus clearance. In a 60-day clinical trial of Betterbrand's Mullein + Chlorophyll Drops, 81% of participants reported less frequent coughing and 77% reported clearer airways. Mullein is available in various forms including mullein tincture and mullein gummies for convenient daily use.

What's the best way to clear mucus after quitting smoking?

Increased mucus production is actually a good sign—it means your cilia are recovering and working to clear debris from your airways. Support natural mucus clearance by staying well-hydrated (aim for 8+ glasses of water daily), using pursed lip breathing techniques, taking steam showers, and considering supplements that support respiratory wellness like NAC and Mullein. The BetterLungs Mullein + Chlorophyll Tincture was clinically studied and showed 73% of participants reported easier mucus clearance.

Can I use natural methods alongside nicotine replacement therapy?

Many people successfully combine natural stop smoking support methods with NRT (nicotine replacement therapy) like patches or gum. However, always consult your healthcare provider before combining approaches. Natural strategies like breathing exercises, dietary changes, and certain supplements can complement medical approaches to smoking cessation. Just be sure to disclose all supplements you're taking to your doctor to avoid any potential interactions.
