EV-001Campaign impact
Official evaluation
CDC Tips: Impact and Results
Supports
Estimated quit attempts, sustained quits, deaths and costs averted.
Limitation
Population attribution and modelling; not proof for an individual viewer.
Open source ↗Health · safety · safeguarding young people
Do not “trust us”.
Check.
Every visual story sits beside its source and inference boundary. No staged photograph proves causation for an individual.
EV-014COPD
Official synthesis
WHO: Chronic obstructive pulmonary disease
Supports
Symptoms, causes, everyday burden and population attribution.
Limitation
Does not establish the cause of one person’s illness.
Open source ↗EV-015Cessation and lungs
Clinical study
Lung Health Study
Supports
Sustained cessation was associated with slower subsequent mean FEV1 decline.
Limitation
A group outcome in the studied population, not an individual promise.
Open source ↗EV-017Vapes and quitting
Living systematic review · 2025
Cochrane: electronic cigarettes for smoking cessation
Supports
Trials of regulated nicotine e-cigarettes found higher quit rates than nicotine-replacement therapy.
Limitation
Applies to adults who smoke in cessation contexts; long-term safety and newer devices need more evidence.
Open review ↗EV-018Heated tobacco
WHO evidence brief · 2023
Heated tobacco products
Supports
HTPs heat tobacco and produce an aerosol containing nicotine and toxicants; they are not harmless.
Limitation
Lower levels of selected chemicals do not establish lower long-term disease risk.
Open WHO brief ↗EV-021Genetics
Multi-ancestry GWAS meta-analysis · 2024
Genetics of tobacco use disorder
Supports
Identifies genetic associations and overlap with other smoking phenotypes.
Limitation
Association is not destiny and does not make a polygenic score an individual clinical answer.
Open study ↗EV-022Psychoactive substances
WHO official topic review
WHO: Psychoactive drugs
Supports
Non-medical use carries significant health risks and can lead to drug use disorders.
Limitation
Risk varies substantially by substance, dose, combinations and context.
Open source ↗EV-023Dependence treatment
WHO/UNODC international standard
International Standards for Treatment of Drug Use Disorders
Supports
Evidence-based medical, psychosocial and recovery interventions, including special needs of adolescents.

Open standard ↗EV-024Anabolic steroids
Endocrine Society scientific statement
Adverse Health Consequences of Performance-Enhancing Drugs
Supports
Summarises cardiovascular, endocrine, psychiatric, hepatic, renal and other risks.
Limitation
Much of the evidence is observational because supraphysiologic doses cannot ethically be assigned in trials.
Open statement ↗EV-025Online recruitment
Europol intelligence notification · 2024/2025
Recruitment of young perpetrators for criminal networks
Supports
Describes recruitment and tasking through social media, coded language and gamification.
Limitation
A European law-enforcement context; warning signs do not prove recruitment in one case.
Open source ↗EV-026Alcohol
WHO official review · 2024
WHO: Alcohol
Supports
Alcohol is toxic, psychoactive and dependence-producing, with links to disease and injury.
Limitation
Risk varies by amount, frequency, health and context; this does not estimate one person's risk.
Open source ↗EV-027Gambling
WHO official review · 2024
WHO: Gambling
Supports
Describes mental-health, relationship and financial harm and the recognised features of gambling disorder.
Limitation
Global estimates are limited and only a qualified professional can diagnose an individual.
Open source ↗EV-028Road safety
WHO official review · access checked in 2026
WHO: Road traffic injuries
Supports
Evidence on speed, alcohol, phones, seat belts, helmets and child restraints.
Limitation
Population estimates do not reconstruct a specific crash or replace national road rules.
Open source ↗EV-029Online abuse
UNICEF policy brief · 2024
Protecting children from violence in the digital environment
Supports
Describes technology-facilitated violence, privacy protection and accessible psychosocial support.
Limitation
Legal classification and a safe response plan vary by country and situation.
Open source ↗Corrections
An error becomes a record,
not a silent rewrite.
A material correction should retain the old claim, new claim, reason, date and reviewer. A named responsible editor and public correction channel remain an organisational release gate.
