Purpose and description
Enable an agent to recognise tobacco-smoking activity, record its pattern and context, distinguish direct participation from smoke exposure, and identify relevant constraints or requested support.
Tobacco smoking is the practice of drawing smoke from burning tobacco into the mouth, with or without inhalation into the lungs, and is a tobacco-specific form of smoking.
It can be Classify a reported episode as tobacco smoking, mixed-substance smoking, another activity or unresolved.; Record product-specific episodes and summarise smoking frequency over a stated period.; Separate smoking participation from other people's smoke exposure.; Check a proposed smoking location against sourced, applicable rules.; Compare reported smoking patterns across time while preserving units and uncertainty.; Record a person's requested change and connect them to appropriate cessation-support resources..
Distinguishing features
The consumed material contains tobacco; nicotine content or a cigarette-like appearance alone does not establish tobacco smoking.
The episode involves combustion of tobacco; a product's marketing name does not establish whether it is smoked.
The participant draws tobacco smoke into the mouth or respiratory tract; simply being near smoke is exposure rather than smoking participation.
Deep inhalation is not required for inclusion, so reported cigar or pipe smoking without inhalation remains within scope.
An episode involving tobacco mixed with another substance belongs here for its tobacco-smoking component and also requires a link to the other substance-use activity.
Scope
+ Tobacco-smoking episodes involving cigarettes, cigars, pipes, waterpipes or other combustible tobacco preparations.
+ A person's tobacco-smoking pattern over an explicitly stated observation period.
+ Tobacco content, product form and smoking apparatus as attributes of an episode.
+ Smoking settings, shared participation and pathways by which smoke reaches other people.
+ Reported intentions, changes in smoking activity and requests for cessation support.
- The broader smoking model, which owns features shared across smoking different substances.
- Vaping, smokeless tobacco use and products operated by heating without combustion.
- Tobacco cultivation, manufacture, retail and product composition as independent subjects.
- Nicotine dependence diagnoses, tobacco-related diseases and clinical treatment plans.
- Passive smoke exposure as an independent exposure history rather than an act of smoking.
- Smoking cannabis or other non-tobacco substances, except for identifying mixed-substance episodes.
Characteristics
- Tobacco-content evidence
- Confirmed tobacco-containing; reported tobacco-containing; confirmed tobacco-free; unknown Establishes whether the episode belongs to this specialisation of smoking.
- Product and apparatus
- Manufactured cigarette; roll-your-own cigarette; cigar or cigarillo; tobacco pipe; waterpipe; other specified; unknown Distinguishes forms of tobacco smoking whose episode boundaries and consumption units differ.
- Combustion status
- Observed combustion; reported combustion; heating without combustion; uncertain Separates smoking from neighbouring activities involving heated tobacco or aerosols.
- Smoking frequency
- Smoking days per stated number of days, with observation dates Makes intermittent and daily patterns interpretable without relying on an undefined smoker label.
- Product-specific consumption
- Cigarettes, cigars, pipe bowls, waterpipe sessions or grams of tobacco per stated interval; retain the original unit Records consumption without treating unlike products or shared sessions as equivalent quantities.
- Smoke-drawing pattern
- Mouth draw only reported; inhalation reported; variable; unknown Describes participation without excluding smoking that does not involve reported inhalation.
- Smoking setting
- Links to location, enclosure, people present and applicable site rules Connects an episode to other people's potential exposure and location-specific constraints.
- Smoking-pattern status
- Current daily; current non-daily; former; never; uncertain, each qualified by definition, reference date and evidence Prevents status labels from silently substituting for an explicit history or classification rule.

Tobacco-smoking boundary Establishes what makes an episode tobacco smoking within the broader class of smoking activities.
Tobacco content, combustion and participation must be established separately to avoid confusing smoking with vaping, heating or passive exposure.
Tobacco and combustion
Identifies the material consumed and the process producing the smoke.
Episode inclusion evidence
Record evidence of tobacco content and combustion independently, retaining uncertainty when either is unclear.
- What establishes that the material burned in this episode contained tobacco? provenance
- Was the tobacco burned, heated without combustion, or used through an unresolved process? boundary
Participation and neighbouring activities
Separates the act of smoking from exposure and identifies activities that share an episode.
Participant role and overlap
Distinguish drawing smoke from being nearby, and link mixed tobacco preparations to any additional substance-use activity.
- Did the person draw smoke into their mouth or respiratory tract, or were they only exposed to smoke produced by someone else? boundary
- Did the preparation contain another substance that requires a linked activity record? boundary
Products and smoking episodes Describes how combustible tobacco products are used and how individual episodes are counted.
A cigarette, a partly smoked cigar and a shared waterpipe session cannot be represented reliably by an undifferentiated count.
Product and apparatus use
Connects the smoking act to the tobacco preparation and apparatus actually used.
Consumed product identity
Record product form, preparation and apparatus sufficiently to interpret the activity, linking detailed product properties to a product model.
- Was the tobacco smoked as a cigarette, cigar, pipe preparation, waterpipe preparation or another specified form? definition
- Which product or preparation details were observed, reported by the participant or inferred? provenance
Episode boundaries and quantity
Defines counting rules for completed, interrupted, resumed and shared smoking activity.
Interpretable episode count
Keep duration, product quantity and participant share distinct, and specify how relighting or sharing affects episode counts.
- What marks this episode's start and end, including interruptions and later relighting? definition
- What quantity did this person smoke, in which product-specific unit, and was the product or session shared? measurement
Smoking pattern and change Represents tobacco-smoking activity across time and the person's stated intentions about it.
One observed episode does not establish a long-term pattern, dependence diagnosis or desire to stop smoking.
Frequency and history
Records smoking days, consumption and dated transitions using explicit observation windows.
Dated smoking pattern
Derive any smoking-status label from a stated definition and history, preserving unknown periods and changes between product forms.
- On how many days in the stated observation window did the person smoke tobacco, and what did they consume on those days? measurement
- Which definition and dated evidence support any current, former or never-smoking classification? provenance
Intentions and support
Records reported reasons, attempts to change and assistance the person actually requests.
Requested smoking change
Distinguish intentions, attempts and observed changes; link clinical assessment or treatment requests to appropriate neighbouring services.
- Has the person stated an intention to stop, reduce or otherwise change tobacco smoking, and what outcome do they mean? definition
- What support has the person requested, and does fulfilling it require a cessation resource or clinical service? action
Smoking setting and constraints Connects tobacco-smoking episodes to shared environments, potential smoke exposure and applicable permissions.
Judging a smoking situation requires knowing where smoke is produced, who is present and which rules apply to that activity.
Shared air and exposure
Records the setting and people potentially reached by smoke without assuming a measured exposure dose.
Episode exposure context
Identify enclosure, proximity and co-presence, linking separately recorded exposure measurements when available.
- Was smoking indoors, outdoors or in a vehicle, and who shared the immediate airspace? measurement
- Is another person's smoke exposure measured, reported or inferred only from their presence? provenance
Location rules and permission
Links smoking decisions to current rules for the specific place and activity.
Applicable smoking constraint
Record the source, date and scope of a smoking restriction or permission rather than inferring it from customary practice or nearby smokers.
- Which dated legal or site-policy source governs tobacco smoking at this location? provenance
- Does the applicable rule permit this proposed episode, prohibit it or require further clarification? action

- vaping - Uses an aerosol generated by heating a liquid rather than smoke from burning tobacco.
- heated tobacco use - Heats tobacco to produce an inhaled aerosol rather than using the combustion characteristic of conventional tobacco smoking.
- secondhand smoke exposure - Describes exposure to smoke from others' smoking rather than personally performing the smoking activity.
- nicotine dependence - A dependence condition rather than an activity; it can arise from nicotine products other than smoked tobacco.

What the second pass must settle
- Which existing registry or world model owns generic smoking, and which shared activity features should this specialisation reference?
- Which smoking-status definitions should be supported for the intended use, particularly for occasional use and periods since stopping?
- How should resumed cigars, repeated pipe lighting and shared waterpipe sessions be counted consistently without obscuring individual participation?
- What evidence is sufficient to classify unfamiliar or hybrid products as involving tobacco combustion?
- Which validated product-specific measures, if any, support comparisons across smoking forms without implying that counts represent equivalent exposure?
