If you are looking for drug rehab in Sydney, the substance involved is important information for an assessment. It does not, on its own, tell you which service or length of stay is appropriate. Start by asking how a service assesses your circumstances and which parts of treatment it actually provides.
This guide helps you prepare that conversation. It does not recommend a withdrawal plan or confirm that any particular Sydney provider treats a substance.
Start with advice before changing your use
The Australian Government advises speaking with a doctor or specialist alcohol and other drug service before reducing or quitting drugs. Withdrawal can be dangerous and treatment needs differ. Explain all substances and prescribed medicines involved, rather than asking only about the drug that concerns you most.
If someone is in immediate danger, call 000. An online directory enquiry is not emergency care.
Separate withdrawal care from rehabilitation
NSW Health describes several treatment settings, including counselling, withdrawal management, day programs and residential rehabilitation. Many residential programs require withdrawal management to be completed before admission.
Ask the intake team:
Our detox and rehab guide explains the distinction in more detail.
Methamphetamine, ice and cocaine: ask about the assessment
NSW Health lists specialist stimulant treatment services as well as broader alcohol and other drug services. Do not assume a residential stay is the only route, or that a service has a dedicated stimulant program because it accepts enquiries about these drugs.
Ask what assessment covers your sleep, mental health, physical health and other substance use. Who provides that assessment? What happens if your needs are outside the program's scope? Ask the team to explain the proposed treatment and why it fits your circumstances.
Heroin and other opioids: discuss ongoing medicines
The NSW Opioid Treatment Program includes medicines such as methadone and buprenorphine and may run alongside counselling or rehabilitation. Discuss options with a qualified treating clinician.
If you already receive opioid treatment, ask a prospective program how prescribing, dispensing and appointments would be coordinated. Can the service support your current treatment? Who will speak with your prescriber before any admission? Do not change prescribed medicines to meet an assumed admission rule.
GHB, GBL and prescription medicines: get medical advice
GHB and GBL withdrawal is a medical emergency. Do not stop on your own, and do not plan a day program around it. If you are dosing around the clock - every two to four hours, including overnight - you are physically dependent. Stopping without medical cover can cause delirium, psychosis, seizures, dangerously unstable heart rate and blood pressure, and muscle breakdown severe enough to shut down the kidneys. It comes on faster than alcohol or benzodiazepine withdrawal, often within hours of a missed dose, and people die from it.
Australian clinical guidance is that anyone at risk of severe GHB withdrawal should be admitted as an inpatient, and that established severe withdrawal needs intensive care involvement. If you are dependent on GHB or GBL now, call 000 or go to an emergency department rather than waiting for a rehab assessment.
NSW Health's withdrawal guidance addresses different substances and care settings. A general rehab listing cannot establish a safe withdrawal arrangement.
Tell the assessing clinician about GHB or GBL use, prescribed medicines and any previous withdrawal problems. Ask which service should assess you and where care would occur. Avoid choosing a start date based on an online detox timetable.
Cannabis, MDMA and mixed use: confirm the service's scope
MDMA does not have an established physical withdrawal syndrome the way alcohol, benzodiazepines, opioids and GHB do. None of this applies to GHB or GBL - see above.
Ask whether the service assesses the substances you use, including combinations. What support is available for associated concerns? Which needs require another clinician or a different setting?
If mental health care is part of the enquiry, use our dual diagnosis questions to clarify who provides it. A program name does not answer these questions.
Prepare a Sydney admission enquiry
Write down what you want help with, current treatment and practical constraints. Ask about referral documents, assessment steps, proposed duration, support after discharge and who confirms the next step. Our GP referral guide and admission checklist can help.
Browse Sydney services and check each profile's published information. Private service enquiries use RehabFinder's callback process; publicly funded profiles provide direct contact options where published. An enquiry is a request for information, not a confirmed admission or clinical recommendation.
