Sources we rely on
Health information on iquitnow.life is drawn from organisations that publish their evidence and methods. Our primary sources are:
- Cochrane Library systematic reviews on tobacco cessation.
- US Centers for Disease Control and Prevention, Office on Smoking and Health.
- NHS Better Health and NICE guidance.
- World Health Organization tobacco programme.
- Peer-reviewed journals indexed in PubMed, cited with their DOI or PubMed link.
- Manufacturer and regulator information for nicotine replacement products and prescription medicines.
How evidence is weighed
When sources disagree, we say so. A systematic review or a large randomised trial outranks a single observational study, which outranks expert opinion. Where only weak evidence exists, the article uses cautious language and does not present the finding as settled. Personal experience from quitters is marked as such and is never used to support a health claim.
Review before publication
Before an article is published, an editor confirms that every statistic, date and quotation matches its source, that links resolve to the page cited, that the article does not contradict current public-health guidance, and that any mention of the iQuit app is accurate about what the app does.
Review after publication
Articles with time-sensitive facts are rechecked when guidance changes and at least annually. Articles we can no longer stand behind are rewritten or removed, and the old address redirects to the current guide on the same topic.
Who writes here
Articles are produced by the iQuit editorial team. The byline on each article names the editor responsible for it, and their profile describes their background. Our editors are writers and researchers, not clinicians. Nothing on this site replaces advice from a doctor, pharmacist or a national quitline.
