Sources & Methodology

How we build the milestones

The milestones (what happens in your body after 24 hours, 3 days, a month or a year) are not our guesses. We map them to published benefit timelines from recognized health organizations and label each milestone with its source. When their guidance changes, we update our content to match.

Health authorities

• NHS (National Health Service, UK)

  Timeline of benefits after quitting smoking, plus alcohol quitting guidance.

• CDC (Centers for Disease Control and Prevention, USA)

  Health benefits of quitting smoking and data on nicotine dependence.

• American Heart Association

  Cardiovascular recovery at each stage after your last cigarette.

• American Cancer Society

  Reduction in cancer risk and other long-term benefits of quitting over time.

• American Lung Association

  Lung and airway recovery after quitting smoking and vaping.

• GamCare

  Self-help tools and the course of gambling recovery (UK).

• NCPG (National Council on Problem Gambling)

  Treatment, relapse prevention and support for problem gambling (USA).

Every milestone shown in the app, with the time since your last dose and the authority it rests on.

Important note

StimuStop is a motivational and educational tool, not a substitute for professional medical care. The timelines describe a typical course — every body is different. For severe withdrawal symptoms (especially with alcohol), always consult a doctor.
