9.3 Reviewing Patterns and Methods of Use

Key Takeaways

  • Task III.C asks counselors to review the client's patterns and methods of use in counseling, not only to score a screen: amount, frequency, route, context, and function.
  • Amount needs units the person and the record can share — standard drinks, milligrams, bags, or points — plus last use, because withdrawal and overdose risk hide in vague words such as sometimes.
  • Route and method change medical risk: injection raises overdose, HIV, and hepatitis C risk, especially with shared equipment; stacking alcohol, benzodiazepines, and opioids depresses breathing.
  • Context and function explain why the pattern persists — sleep, trauma numbing, social belonging, performance, or withdrawal avoidance — and they guide later coping work without moralizing.
  • Harm-reduction review (never use alone, naloxone, new syringes, do not mix depressants) is counseling, not permission; shaming the method shuts down the history you still need.

9.3 Reviewing Patterns and Methods of Use

Quick Answer: Task III.C is review the client's patterns and methods of use. In counseling you still need amount, frequency, route, context, and function. "Uses heroin sometimes" is not a pattern. Injection, using alone, and mixing depressants (alcohol, benzodiazepines, opioids) are high-risk methods that belong in the review even when the person is not asking for abstinence today.

Assessment instruments in Domain II collect much of this history. Domain III tests whether you can revisit and use it in treatment: to make risk visible, to match coping skills to the real slot in the day, and to update the picture when the story changes because rapport grew. Independent ADC prep by OpenExamPrep treats pattern review as a repeating counseling task, not a one-time intake field.

What a usable pattern contains

A complete counseling review can be remembered as AFRCF: amount, frequency, route, context, function. Add last use and periods of abstinence every time, because withdrawal and overdose sit on those two facts.

DimensionQuestion that produces dataVague report that fails the item
Amount"What is in a typical dose, and what is in a heavy day?" Convert alcohol to standard drinks (in the U.S., about 14 grams of ethanol: 12 oz of 5% beer, 5 oz of 12% wine, 1.5 oz of 40% spirits)"I drink socially" / "a little bit"
FrequencyDays per week, binge versus daily, morning use"Whenever"
Route / methodOral, smoked, snorted, injected (IV, IM, SQ), transdermal, rectal; crushed pills; shared equipment"I just use"
ContextAlone or with others, time of day, payday, after arguments, before work, in the car"It depends" with no example
FunctionWhat the use does: sleep, numb trauma, belong socially, perform, avoid withdrawal, feel pleasure"I have no idea" accepted without a probe
Last useSubstance, amount, time"A while ago"
Abstinence windowsLongest stretch, what helped, what ended itSkipping this because the person is using now

Worked conversion: "A pint of vodka most nights" is not a personality description. An 8.5 oz pint of 40% spirits is on the order of six to seven standard drinks, and "most nights" is frequency. If they also take clonazepam "to come down," you now have a method: stacked central-nervous-system depressants. That is counseling content for today, not a lecture saved for a later module.

Revisit the pattern when the alliance can hold more truth. A courtesy story in week one ("only weekends, only beer") may become "a fifth on weeknights, plus leftover Xanax" in week four. Updating the review is Task III.C, not an accusation that they lied.

Amount and frequency without a cross-examination

Tone stays curious. A calendar or typical-week map (visual channel from 9.1) often beats a demand for lifetime totals.

  • Pin peak and typical separately. Overdose and withdrawal hide in the peak. Function often hides in the typical.
  • For opioids, amount in "bags" or "points" is still data if you also ask what happens if they take less (withdrawal onset).
  • For stimulants, frequency may be binge days rather than daily milligrams; still get duration of the run and crash.
  • For cannabis, concentrates versus flower change amount; "I smoke weed" does not.

Closed questions belong after an open narrative: "Was that a pint or a fifth?" Stacking "how much, how often, where, why, and with whom" in one breath produces an answer only to the last clause.

Route and high-risk methods

Method of use is how the substance enters the body and how it is combined. Route changes onset, intensity, and medical risk.

MethodWhy it is high-risk in counseling reviewCounseling move
InjectionFaster, harder-to-control dose; overdose risk; HIV; hepatitis B and C; bacterial infections, abscess, endocarditis; vein damageAsk last injection, sharing of syringes, cookers, cotton, and water; offer sterile-equipment and never-use-alone information without treating the person as their route
Smoking / chasingRapid onset; lung injury depending on substance; still overdose risk with fentanyl-adulterated supplyDo not rank smoking as "safe" simply because it is not injection
SnortingMucosal damage; still systemic dose; sharing straws can spread blood-borne virus riskInclude in the method review; do not skip because it seems "less serious"
Oral stacking of depressantsAlcohol, benzodiazepines, opioids, and often gabapentin or sedating muscle relaxants add respiratory depressionTeach the combination as a method, not as proof of moral failure
Using aloneIf overdose happens, no one can give naloxone or call 911"Who is with you when you use?" is a pattern question
Unknown fentanyl supplyDose surprise even in pills or cocaine the person did not intend as an opioidFentanyl test strips and naloxone belong in the review where legally and programmatically available

CDC has long identified injection-drug use as the most commonly reported risk for new hepatitis C infections in the United States, which is why a counseling review that never asks about sharing equipment is incomplete. CDC's polysubstance-overdose teaching is the other hard fact: opioid-involved overdoses often involve other drugs or alcohol. Combinations of illegally made fentanyls with benzodiazepines, alcohol, other opioids, or stimulants are part of how people actually die. You do not need a memorized year-by-year percentage to use the clinical rule: stacking depressants is a high-risk method.

Harm-reduction review is still counseling. You can say, "I want you alive tomorrow," and still support an abstinence goal if that is the plan. Shaming injection ("real addicts shoot") both uses prohibited language and ends the history.

Context and function of use

Context is the setting. Function is the job the substance is hired to do. Same drug, different jobs, different later interventions.

FunctionWhat it sounds likeWhy the review matters
Withdrawal avoidance"I use so I can work and not get sick"Medical and MOUD pathways; this is not "they like getting high"
Sleep / shut-off"It is the only way my brain stops"Treating only willpower misses insomnia and trauma
Trauma numbingUse after flashbacks, after a partner's violenceSafety and later trauma-informed work (Domain III.H); do not demand a trauma narrative in the same breath as the amount
Social belonging"That is how my crew is"Refusal skills and network change, not a sermon about friends
Performance / energyStimulants for shifts, exams, weightSchedule and occupational context
Pleasure / boredom"I miss the feeling"Later coping must offer something for that slot, or the plan is empty

A person who drinks a pint alone at 5 p.m. to kill anxiety is not the same counseling problem as a person who injects on payday with friends and uses a little on weekdays. Frequency numbers could look similar on a bad form. Function and context are how you tell them apart.

Counseling review is not a diagnosis substitute

DSM-5-TR criteria (Domain II) still need a full assessment. Pattern review does not replace that. It also does not replace ASAM dimensional placement. What III.C adds is the living picture you use in session: risk, triggers, and methods you can actually plan around.

If the person describes a method that is likely to kill them today (a plan to inject a large unknown fentanyl dose alone, or to mix a fifth with leftover methadone and alprazolam), you are no longer only reviewing a pattern. You are at the edge of III.D crisis. Stay with the risk; do not finish the calendar first.

Worked counseling review

A 38-year-old in week three says, "I told intake I only drank beer." Rapport has grown. A typical-week map now shows a pint of vodka five nights, clonazepam from a friend on two of those nights, and two days of smoked fentanyl after a fight with a partner. Amount: pint plus unknown benzodiazepine plus fentanyl. Frequency: most days. Route: oral depressants plus inhalation. Context: evenings, after conflict, often alone. Function: sleep and numbing. High-risk methods: mixed depressants, using alone, unknown opioid potency. The counseling move is to make that pattern visible, offer naloxone and a never-use-alone plan, and ask what they want to change first — not to open with "See, you were lying," which would spend the alliance you just earned.

Exam traps

  • A DSM code does not replace amount, route, and last use.
  • Smoking is not automatically safer than injection for overdose if the supply is fentanyl.
  • Mixing alcohol with benzodiazepines is not a way to "balance" opioids.
  • Harm-reduction questions are not the same as encouraging use.
  • "Sometimes" is not a frequency.
