Cannabis is the most widely used illicit drug in Australia. Most people who use cannabis don't develop dependence, but for the minority who do, daily use can affect motivation, mental health, sleep, and relationships. Treatment is usually outpatient and psychological.

You don't need to tick every box. Even a few of these — particularly from the right column — usually mean it's worth a call.
If signs from this column apply to cannabis use, please don't wait — call your state alcohol & drug line or talk to your GP this week.
Cannabis withdrawal is generally considered mild. Medical detox is not usually required, but a GP or addiction medicine specialist can help manage the early days — sleep, mood, and cravings — which is when most attempts to stop unravel.
The current standard of care for cannabis dependence in Australia integrates a stabilisation and assessment phase, evidence-based psychological therapy (cognitive behavioural therapy, motivational interviewing, and where relevant trauma-informed work), structured peer support, and aftercare planning that begins on day one rather than at discharge. Programs that follow this stack consistently produce better long-term outcomes than ones that rely on a single component — even if that component is residential rehab.
Quality signals worth looking for when evaluating a cannabis program: an addiction medicine specialist involved in care (not just a GP), routine assessment and treatment of co-occurring mental health conditions, a clearly described aftercare plan that runs for 12 months or more, family-inclusive options where appropriate, and honesty about cost. Programs that emphasise comfort or amenities over clinical depth, or that cannot articulate their aftercare model, are worth approaching with caution regardless of the price tag.
The first 90 days after stopping cannabis are usually the hardest. Acute withdrawal is typically uncomfortable rather than dangerous and resolves over 1 to 4 weeks. Post-acute symptoms — sleep disturbance, mood changes, cravings — can persist for months and are the most common period for relapse. Most people describe months 3 to 6 as the point at which their head genuinely starts to feel clear; months 6 to 12 as the period in which routines, relationships, and purpose are rebuilt.
The literature is consistent that aftercare engagement for at least 12 months after primary treatment is the single strongest predictor of long-term recovery — stronger than program length, sector, or any specific therapy modality. Strong aftercare for cannabis is rarely one thing: it is a stack of weekly counselling tapering over months, peer support (SMART Recovery, AA, NA, CA depending on fit), continued GP and addiction-medicine follow-up, ongoing relapse-prevention medication where relevant, and a written relapse-prevention plan that names triggers and responses you have rehearsed.
For the cost picture, see our 2026 rehab cost breakdown or the free rehab access guide. For the treatment-format question, the inpatient rehab guide, the outpatient programs guide, the medically supervised detox guide, and the at-home detox guide each cover one format in realistic detail. For the long-form articles on practical decisions, see how to choose a rehab and the articles index.
The right format isn't the most expensive one or the most marketed one — it's the one that fits the severity of dependence, the stability of your home environment, and the practical realities of work, family, and finances. There's no single right answer, but the framework below covers most situations.
Severe daily alcohol use, daily opioid use (heroin, oxycodone, fentanyl), and long-term high-dose benzodiazepine use all involve withdrawal that can be medically dangerous and shouldn't be attempted without supervision. Severe alcohol withdrawal can cause seizures and delirium tremens. Benzodiazepine withdrawal can cause seizures and prolonged neurological symptoms. Opioid withdrawal isn't usually life-threatening but is intensely uncomfortable and produces high relapse risk if unmedicated. For these substances the safest first step is a 5–10 day medically supervised detox in a hospital, dedicated detox unit, or supervised home-detox program — followed by rehab, not instead of it.
Residential (inpatient) rehab — staying onsite at a facility for 28 days to several months — is the right choice when home life is destabilising recovery, when previous outpatient attempts haven't held, when there's significant co-occurring mental health concern, or when the person needs a complete break from current routines to reset. Programs of 60 and 90 days consistently show better long-term outcomes than 28-day programs in the research, particularly for severe dependence. The trade-off is time away from work and family — 28 days minimum, often more — and cost in the private sector.
Outpatient programs — living at home, attending sessions 2 to 5 times per week — are the most common form of AOD treatment in Australia, not because they're a "lite" version, but because for many people they're the more clinically appropriate format. Outpatient suits people whose home environment is reasonably stable, who can keep working, who want to integrate recovery skills into normal life from day one, or whose dependence is at a level where the structure of residential isn't necessary. The core therapeutic content — CBT, group therapy, relapse-prevention skills — is the same as residential. The wraparound is what differs.
The single most consistent finding in addiction outcome research: people who engage with structured aftercare for 12 months or more after their primary treatment episode have dramatically better long-term outcomes than those who treat treatment as a one-off. Strong aftercare is rarely one thing — it's a stack: weekly counselling tapering over months, peer support (SMART Recovery, AA, NA, CA), continued GP and addiction-medicine follow-up, ongoing medication where relevant, and a written relapse-prevention plan. When evaluating any program, the question "what does aftercare look like in the 12 months after I leave?" is the single most predictive question you can ask.
Public (government-funded) detox and rehab is free at the point of access for Australian residents, though wait lists can range from days to several weeks. Private inpatient rehab typically costs $25,000–$45,000 for a 28-day program; some private health insurance funds cover a portion. We can help you understand your options on a free confidential call.
Detox (withdrawal management) is the short medical phase — usually 3–10 days — where the body adjusts to being without the substance. Rehab (rehabilitation) is the longer-term work that follows: counselling, group therapy, relapse prevention, and rebuilding daily life. Most people benefit from doing detox first, then rehab — going straight into therapy while still withdrawing rarely sticks.
No. People who seek help earlier — before losing housing, jobs, or custody — generally have shorter, easier recoveries. Waiting for rock bottom is one of the most damaging myths in addiction recovery. If your use is affecting any part of your life, that's enough.
Treatment in Australia is bound by strict privacy laws (the Privacy Act 1988 and state-specific health records legislation). Clinics cannot disclose your attendance to employers without written consent, and Medicare records of mental health treatment are not visible to employers. Many people take leave under general medical grounds without disclosing the specific reason.
It depends on the program. Outpatient programs let you continue work and family commitments, with sessions in the evenings or weekly. Residential (inpatient) programs require 28 days to several months away. Many Australians use accumulated annual leave, long service leave, or carer's leave. Some employers offer paid 'addiction leave' under EAP programs.
