ClariLung's 30+ health milestones aren't invented. They're drawn from decades of public-health research by the CDC, NHS, American Lung Association, NIDA, and WHO. This page explains our sources and what the evidence actually says.
ClariLung is not a medical device and does not provide medical advice. The health milestones shown in the app are general wellness information based on established public-health research. They are not a substitute for guidance from a qualified healthcare professional. If you have concerns about your health or withdrawal symptoms, please speak with a doctor.
ClariLung cites organizations — not individual studies. We reference well-established, verifiable bodies of research from the world's leading public-health institutions. We do not fabricate paper titles, author names, DOIs, or study URLs.
The CDC's Office on Smoking and Health publishes comprehensive data on cessation benefits, chemical exposure, and long-term cardiovascular and respiratory recovery. ClariLung draws on their published cessation timeline research.
The NHS publishes detailed timelines of what happens to the body after stopping smoking, used in public smoking-cessation programs across the United Kingdom. These timelines inform several of ClariLung's early milestones.
The ALA's research and advocacy work covers both tobacco and cannabis cessation. Their published health-benefit timelines for quitting smoking and vaping are directly referenced in ClariLung's milestone data.
NIDA publishes research on cannabis use disorder, THC clearance timelines, and cognitive recovery. ClariLung's weed-specific milestones draw on this body of work.
WHO reports on global tobacco use, health outcomes, and cessation effectiveness inform the broader context of ClariLung's health claims and risk-reduction framing.
What happens to your body when you quit — across all four substances ClariLung supports. Timeline items are labeled with the substance(s) they apply to.

ClariLung is not a medical device. These milestones are general wellness information, not medical advice.
Each milestone shown in ClariLung is drawn from established cessation research. We do not extend claims beyond what the public-health consensus supports. When the evidence covers cigarette smokers specifically, we label it that way.
Vaping, cigarettes, weed, and cigars each have different chemical profiles and different recovery timelines. Where the research is substance-specific — like THC clearance times or oral cancer risk reduction — we apply it to the right substance. We don't mix them.
We cite organizations, not specific papers. We do not manufacture paper titles, author names, DOIs, or study links. If you want to read the research, go to cdc.gov, nhs.uk, lung.org, nida.nih.gov, or who.int and search for smoking cessation.
ClariLung is a wellness and behavior-change application. It does not diagnose, treat, or cure any condition. It does not replace a doctor. For serious medical concerns or if withdrawal symptoms are severe, please speak with a healthcare professional.
