Medical Cannabis vs Illegal Possession in NSW: What You Must Know

BySydney Criminal Lawyers

If you’re in New South Wales and prescribed medical cannabis by a registered practitioner, you might be concerned about potential legal complications. People regularly search for a medical cannabis lawyer Sydney, cannabis prescription defence Parramatta or possession cannabis lawyer Wollongong.

It’s vital to understand both your legal rights and the serious risks of illegal possession, even if what’s in your hand was medically prescribed.

While legitimate Australians can access cannabis through tightly controlled schemes (TGA SAS, Authorised Prescriber, approvals from NSW Health), possession without prescription remains a criminal offence, punishable under NSW’s Drug Misuse and Trafficking Act 1985 (DMTA).

There’s no ‘medical use’ defence to simple possession charges, even for patients. At National Criminal Lawyers®, our experienced team frequently helps concerned clients looking for a drug possession lawyer or drug supply lawyer.

How Medical Cannabis Is Legally Accessed

Medicinal cannabis in NSW is governed by:

Access must follow:

  1. A valid prescription under TGA Special Access Scheme or Authorised Prescriber scheme;
  2. Approval from NSW Ministry of Health for any compounded Schedule 8 product;
  3. The product must be legally imported or manufactured, not raw plant form under local cultivation.

Those accessing cannabis legally may still be prosecuted if in unauthorised possession, unless they satisfy strict access criteria.

Illegal Possession: Section 10 DMTA

Under Section 10 of the Drug Misuse and Trafficking Act 1985, possessing cannabis remains an indictable offence, with a maximum penalty of two years imprisonment and/or a $2,200 fine.

Courts have repeatedly held that:

“It is not a defence… that the person used the cannabis for a legitimate medical reason”.

However evidence of chronic illness or personal hardship may be considered during sentencing, though conviction is still possible.

Driving with Medicinal Cannabis is not a Legal Defence

Under Section 111 of the Road Transport Act 2013 (NSW), any detectable THC in your blood or saliva constitutes a drug-driving offence, regardless of impairment or prescription status.

As affirmed by the NSW Court of Criminal Appeal in Narouz, drug driving is an absolute-liability offence. This means no medical defence or honest mistake is allowed.

Even if you hold a prescription, a roadside saliva test showing THC can lead to arrest, licence disqualification, and court charges.

Cannabis Trends & Sentencing Principles

According to rulings under DMTA:

BOCSAR and NSW parliamentary reports show increasing calls for reform, including removing custodial sentences for minor personal-possession offences. However, for now, conviction remains possible even in small-scale cases.

Case Examples That Illustrate Legal Treatment

“Mr Hemp” (Aaron Armstrong, Coffs Harbour, 2025)

Charged with supply of cannabis and cannabis oil, Armstrong possessed over 1kg dried leaf and 1.8kg oil. Defence emphasised minimal THC (3%), medicinal use by patients, and no evidence of harm. The court handed down a 12‑month Community Corrections Order, acknowledging a shift in judicial approach for medically-motivated cases.

Illawarra Developer (Robert Mank, 2024)

Possession of nearly 100 cannabis plants amounted to a commercial operation, despite claims it was a personal “gardening project.” The court imposed a 26‑month intensive correction order, noting inability to justify such scale for medical use. General deterrence principles strongly influenced sentence.

These cases show judicial willingness to avoid prison in atypical medically nuanced contexts, but convictions for illegal possession still occur, even where health factors are present.

Related Offencaes & Legal Overlaps

  • Cultivation (s 23/23A DMTA): Growing cannabis, even for personal medical use without government approval, is criminal.
  • Supply (s 25 DMTA): Even gifting cannabis can trigger supply charges if quantity exceeds strict thresholds, deemed supply applies if over 300g leaf absent alternative explanation.
  • Drug driving offences under the Road Transport Act carry zero tolerance for prescription status.

Key Legal Insights & Recommendations

1. Medical prescription does not mean automatic protection:

Even valid access pathways can’t override criminal provisions under DMTA or RT Act.

2. Drug-driving detection is absolute-liability:

Detected THC in saliva, even from medically prescribed cannabis, leaves no defence.

3. Small possession may attract cautioning,

But caution eligibility is limited to cannabis leaf ≤ 15g, clean record, admission, no concurrent criminal history.

4. Mitigation is vital if charged:

Highlight medical diagnosis, TGA-approved supply, prompt disclosure, and lack of intent to traffic.

5. Judicial reform is possible:

NSW parliamentary bodies have recommended repeal of custodial penalties for small possession. Legislation may change soon.
