Cues, craving and relapse
- Concept
People, places and moods linked to past drug use can trigger craving long after stopping; relapse is common and is a reason to adjust treatment.
What it is
Through classical conditioning, cues repeatedly paired with drug use (people, places, objects, times of day, emotions) come to trigger craving and body responses on their own; this is cue reactivity. Together with stress and re-exposure to a small amount of the drug, cues are the main triggers of relapse. Addiction is a chronic, relapsing condition: relapse rates are similar to those of other chronic illnesses such as hypertension and asthma. Relapse prevention teaches people to recognize high-risk situations and to cope with them, and after a period of abstinence tolerance is lost, which raises overdose risk.
Key facts
- Drug-cue associations last for years, which is why craving can return suddenly in a familiar setting.
- The abstinence violation effect: after a slip, thinking ‘I have ruined everything’ makes full relapse more likely.
- Craving can grow during the first weeks to months of abstinence before it fades, shown in animal studies and in people.
- Extinction of cues in the clinic does not always transfer to the real world, because extinction learning is context-dependent.
- Relapse prevention, mindfulness-based relapse prevention, contingency management and medications for opioid, alcohol and tobacco use disorders lower relapse.
Relapse triggers and responses
| Trigger | How it works | Coping example |
|---|---|---|
| Drug-associated cues | Conditioned responses to people, places, objects and times | Change the route home that passed the old bar; remove paraphernalia |
| Stress and negative emotions | Stress systems drive use for relief (negative reinforcement) | A planned call to a support person, exercise or a brief breathing practice |
| Priming (a small amount) | A single use reactivates drug seeking | Treat a slip as information and contact the treatment team quickly |
| Positive emotions and celebrations | Social cues and lowered vigilance | Plan alternatives in advance for parties and holidays |
Clinical notes
- People leaving detoxification, hospital or prison after opioid abstinence are at high risk of overdose; naloxone and fast linkage to treatment save lives.
- Asking a patient ‘what were the hours before the relapse like?’ often reveals a concrete trigger to plan for.
Test yourself
Think of the answer, then tap the question to see it.
What is cue reactivity?
Craving and body responses triggered by stimuli previously paired with drug use, through classical conditioning.
What are the three classic triggers of relapse?
Drug-associated cues, stress, and re-exposure to the drug (priming).
How do relapse rates in addiction compare with other chronic diseases?
They are similar to rates in hypertension and asthma, which supports treating addiction as a chronic illness.
Why is overdose risk high after a period of opioid abstinence?
Tolerance is lost, so the previously used amount can now be fatal.
