Nicotine
Nicotine or tobacco use recorded as an occurrence, separate from any protocol.
Evidence category: Clinical study. This describes the source category, not approval or certainty.
Regulatory statement in source: Not separately recorded; do not infer approval from the evidence category.
Logging nicotine or tobacco use as an occurrence mirrors how cohort studies quantify cigarettes smoked per day for mortality analysis. Two large prospective cohorts found that consistently smoking only a few cigarettes across adulthood still carried meaningfully higher mortality risk than never smoking.
Benefits reported in the imported source
- Logging each use creates an objective count that self-recall alone tends to underestimate.
- A visible log of occurrences can make patterns of use easier to notice over time.
- Cohort data show mortality risk drops substantially after smoking cessation, with earlier quitting linked to larger reductions in risk.
Risks and limits
- Large cohort studies found even long-term smoking of ten or fewer cigarettes daily linked with meaningfully higher all-cause and lung cancer mortality than never smoking.
- No level of cigarette smoking studied in these cohorts was free of added mortality risk.
- Nicotine use is linked with cardiovascular and respiratory disease risk that scales with cumulative exposure.
Source bottom line: Two large prospective cohorts found that even low-intensity, long-term cigarette smoking carried meaningfully higher mortality risk than never smoking, with no threshold identified as risk-free.
Uncertainty: Reference information only. Not medical advice.
