Built for smokers

Quit smoking for real.

Cigarettes are one of the most researched addictions in history — and quitting is still brutally hard. ClariLung knows the cigarette-specific milestones, the 72-hour wall, and the triggers that catch you off guard. Every breath without smoke is your lungs rebuilding.

What do you smoke?

Your cigarette. Your plan.

Marlboros aren't menthols. Roll-your-own isn't a pack-a-day. ClariLung accounts for your cigarette type.

Regular

Full flavor filtered — the classic. High chemical load, well-studied recovery curve.

Light / Ultra Light

Low-tar, filtered. Often smoked more deeply — not actually less harmful.

Menthol

The menthol numbs the throat irritation, making it easier to inhale more, more often.

Roll-Your-Own

Hand-rolled tobacco. Users often underestimate intake — tracking matters.

Why cigarettes are hard to quit

Decades of conditioning don't quit easily.

The chemical and psychological hooks in cigarettes are uniquely powerful. Knowing them helps.

7,000+ chemicals

A cigarette delivers over 7,000 chemicals with each smoke, including ~70 known carcinogens. The body normalizes to these quickly and protests when they stop.

Deep-set ritual

The smoke break is woven into work schedules, social life, after-meals, and morning coffee. The habit isn't just chemical — it's structural.

Withdrawal peaks at 72 hours

Physical nicotine withdrawal peaks around 72 hours. The third day is the hardest — knowing that helps you prepare rather than surrender.

Social cues are relentless

Other smokers, certain venues, specific emotions — decades of conditioning mean cues can trigger urges years after quitting.

Your recovery timeline

What happens when you stop smoking.

Recovery typically begins within the first 20 minutes. These milestones are specific to cigarette smokers — sourced from CDC, NHS, and American Lung Association cessation research.

20 minutes
Blood pressure easing
Within about 20 minutes, heart rate and blood pressure typically begin to normalize.
8 hours
Oxygen levels rising
By around 8 hours, carbon monoxide roughly halves and blood oxygen rises.
24 hours
Heart attack risk beginning to fall
After a day, carbon monoxide has cleared and heart-attack risk begins to fall (per public-health data).
48 hours
Taste & smell recovering
Around 2 days, many ex-smokers notice taste and smell improving as nerve endings recover.
72 hours
Nicotine has cleared
By about 3 days, nicotine has cleared and bronchial tubes tend to relax.
2 weeks
Two weeks strong
Around two weeks, circulation often improves and activity tends to get easier.
1 month
One month clear
By a month, the lungs' cilia are typically regrowing.
3 months
Three months free
By three months, lung function often improves notably and coughing tends to ease (per public-health data).
6 months
Six months smoke-free
Around six months, airways are usually much less inflamed.
1 year
One year free
At a year, the excess heart-disease risk is about half that of a smoker (per public-health data).
5 years
Five years free
By around five years smoke-free, stroke risk approaches that of a non-smoker (per public-health data).

ClariLung for smokers

Everything between cigarettes.

Six tools built around how cigarette addiction actually works.

Cigarette-by-cigarette tracking

Log each cigarette. Watch daily count drop. Know your worst trigger windows — coffee at 8am, stress at 3pm.

AI Coach for the 72-hour wall

The hardest part is day three. The AI Coach knows this and is ready — with your history, your patterns, and strategies that worked before.

Taper plan: cut gradually

Reduce cigarettes per day along a quadratic curve. Less shock to the system, better long-term adherence than cold turkey alone.

Lung recovery milestones

From 20 minutes (heart rate and blood pressure typically begin easing) to 5 years (stroke risk approaching a non-smoker's, per public-health data). Real data for cigarette smokers specifically.

Craving tools at the peak

Cravings last 3–5 minutes. Breathe through it with a guided exercise, or tap to log it and watch it pass.

Money saved — visible and real

A pack-a-day habit at $10/pack is $3,650 a year. ClariLung shows your savings in real time, day by day.

Common questions

An individual craving usually passes within three to five minutes whether or not you smoke. The first few days are the hardest; physical withdrawal typically peaks around 72 hours and fades over the following weeks. ClariLung helps you get through each craving and keeps the longer trend visible.
Recovery starts fast. Within a day, most nicotine has cleared and heart rate and blood pressure begin easing. Over weeks to months, circulation and lung function often improve and coughing tends to settle. ClariLung lays out these milestones, sourced from the CDC, NHS, and American Lung Association.
Both work; the best method is the one you'll stick with. Cold turkey suits some people, but a gradual taper — optionally paired with nicotine replacement therapy — is easier for many. ClariLung builds a personalized taper plan and lets you log NRT so you see your real reduction.
Yes — most people who quit for good have several attempts behind them. ClariLung treats a slip as data, not failure: it logs the moment, learns your high-risk windows, and helps you start the next streak prepared.
