Ecological Momentary Assessment

Capture cannabis use the moment it happens — not reconstructed days later

SmokingTracker uses EMA to log sessions, mood, and triggers in real time. Three taps. No cognitive load. No recall bias distorting your clinical data.

The recall problem

Cannabis affects short-term memory. Your clients aren't lying — they just can't recall.

Regular cannabis use impairs episodic memory encoding. By the time a client sits across from you, a full week of sessions, moods, and triggers has dissolved into a vague "about the same." EMA fixes this — by capturing it the moment it happens, not reconstructed in a clinical setting days later.

Three-tap logging

Minimum friction. Maximum compliance.

Cannabis use disorder clients often have impaired working memory during active use. A complicated logging interface guarantees low compliance. SmokingTracker's three-tap interface logs a full session in under five seconds — removing the barrier to real-time capture.

  • Three required taps — substance, amount, method
  • Optional: mood rating, craving score, trigger, location, notes
  • Works in any mobile browser — no app store download
  • Fast-use warning notifies the client in the moment

Client logging a cannabis session — three-tap interface
Mood & trigger capture

The data that vanishes without EMA

Research shows that craving, state anxiety, and social context predict use episodes — but only when measured in the moment. By the time a client sits across from you, these proximal triggers are gone. EMA captures them before they dissolve.

  • Mood rating tied to each session
  • Craving score logged independently of use
  • Trigger categories: social, stress, boredom, habit, pain
  • Location context captured automatically (optional)

Longitudinal statistics

Patterns that only emerge over time

Individual sessions are noise. Patterns are signal. SmokingTracker aggregates EMA data into weekly trends, time-of-day heatmaps, trigger frequency rankings, and mood-use correlations — giving both client and clinician a picture that no single session can provide.

  • Week-over-week consumption trends
  • Time-of-day usage heatmap
  • Top trigger categories by frequency
  • Smoke-free days calendar and streak counter

Evidence base

EMA is the gold standard for substance use research

SmokingTracker's logging methodology is built directly on peer-reviewed EMA research.

Ecological validity
EMA dramatically outperforms retrospective recall
Capturing behavior as it happens removes the systematic distortions of memory-based self-report. 1
Proximal triggers
Craving and social context predict use — in real time only
Associations between triggers and use episodes are only detectable in momentary data — they vanish in retrospective reports. 23
CUD-specific validation
EMA validated for cannabis use disorder specifically
Mood–craving–use dynamics in CUD are reliably captured by EMA — and missed entirely by structured clinical interviews. 6
Clinical outcomes
Timely real-time data improves treatment outcomes
Systematic, timely client feedback improves clinical outcomes in substance use disorder settings — the foundation of Measurement-Based Care. 45

How EMA logging works

From invitation to real-time data in minutes

No technical setup for the client. No app store required.

1
Clinician sends an invite
Create an invitation from the Practitioner Dashboard. The client receives a link — email, SMS, or manual handoff. No app download required.
2
Client logs in the moment
Three taps to log a session. Optional mood, trigger, and notes fields. The data is captured when it's accurate — not recalled later.
3
Clinician sees structured patterns
EMA data aggregates into trends, trigger patterns, and traffic light status. Session-ready before the client walks in.
