F11 — Mental and behavioural disorders due to use of opioids: facilitator sheet
Teaching objective
As with every category in this block, the central question is whether the six dependence-syndrome features — desire/compulsion, control difficulty, tolerance, withdrawal, neglect of alternatives, continued use despite harm — cluster together, rather than whether opioid use is occurring at all (for example, a person can use prescribed opioids appropriately for pain without meeting these criteria). The second key question specific to F11 is severity triage: opioid withdrawal, however severe subjectively, is managed very differently from alcohol or sedative withdrawal precisely because it lacks the seizure/delirium risk those carry.

Worked example
Show scenario
A 55-year-old has been prescribed a strong opioid for severe chronic back pain for the past two years. Over that time the effective dose has been increased twice by her physician as pain control lessened. She takes the medication as prescribed, has never taken extra without approval, and manages her work and family life without disruption. She mentions mild discomfort if a dose is delayed slightly.
Reveal step 1
Step 1 — Check for control difficulty: she takes the medication exactly as prescribed, with no reported difficulty limiting or controlling use.
Reveal step 2
Step 2 — Check for neglect of alternative interests: work and family functioning are both intact, with no evidence of priorities shifting toward obtaining or using the medication.
Reveal step 3
Step 3 — Note tolerance and mild withdrawal-type discomfort: dose increases and mild discomfort with delay are expected physiological accompaniments of sustained opioid treatment, not evidence of dependence syndrome by themselves.
Reveal step 4
Step 4 — Weigh the overall cluster: only tolerance and a mild physiological dependence are present; the compulsion, control-difficulty, and continued-use-despite-harm criteria are absent.
Reveal step 5
Conclusion — This is best understood as appropriate, supervised medical opioid use, not F11 dependence syndrome, because physiological tolerance and mild withdrawal-type phenomena alone do not meet the fuller dependence-syndrome cluster.
Comparison points
F11 is distinguished from appropriate medical opioid use by the presence of the dependence cluster rather than supervised, indicated treatment; from F10/F13 by opioid withdrawal's characteristic symptom pattern and markedly lower acute medical danger; and its psychotic-disorder subtype from an independent psychiatric illness by temporal relationship to use.
Misconception prompt
Assuming every withdrawal state carries the same medical danger: "Withdrawal is withdrawal — if it's distressing, it must be dangerous."
Ask the class why this reasoning fails before revealing the explanation below.
Reveal why it fails
Across this block, withdrawal states differ sharply in medical danger even when they are similarly distressing. Alcohol and sedative/hypnotic withdrawal carry a genuine risk of seizures and delirium. Opioid withdrawal is intensely distressing but not typically medically dangerous by itself. Conflating subjective distress with medical danger leads to both over-treating low-risk withdrawal and, more seriously, under-monitoring genuinely high-risk withdrawal.
Discussion prompts
Prompt 1
Without looking back at the page, state why opioid withdrawal is generally considered less medically dangerous than alcohol withdrawal.
Prompt 2
Name one feature that would make you consider appropriate medical use rather than dependence syndrome in an opioid case.
Prompt 3
Explain in one sentence why tolerance and a mild withdrawal-type symptom alone are not enough to establish dependence.
Summary
The same six-criteria dependence-syndrome cluster applied to opioids, with a key added distinction: opioid withdrawal is intensely distressing but not typically medically dangerous, unlike alcohol or sedative withdrawal.
