Drug Possession Defence

Drug-possession allegations require proof of possession and the necessary knowledge. Finding a substance in a house, vehicle, bag or shared space does not by itself resolve who possessed it or what that person knew.

KEY ANSWER

The position in brief

Section 5(1) Misuse of Drugs Act 1971 creates the offence of unlawful possession of a controlled drug. The prosecution must establish that the defendant possessed the substance and that it was a controlled drug.

Section 28 provides important knowledge-related protections. A defendant who genuinely lacked knowledge, suspicion or reason to suspect relevant facts may be able to raise the statutory defence, after which the prosecution bears the legal burden in accordance with the case law.

Legal issues

Key issues include legal possession, knowledge, the identity and classification of the substance, lawful authority or prescription where applicable, and attribution in shared premises or vehicles.

Evidence that matters

Evidence may include search records, body-worn video, fingerprints/DNA, forensic drug analysis, photographs, messages, location of the substance and evidence of who controlled the relevant area or container.

Reasonable lines of enquiry

Enquiries may include forensic attribution, identifying other occupants/users, reviewing search footage and continuity, obtaining prescription or lawful-possession documents and testing the prosecution theory of control.

What happens next

Possession offences are generally dealt with according to drug class, quantity, circumstances and record. Outcomes can range from out-of-court disposal in appropriate cases to court proceedings.

Immediate steps

Keep search and seizure paperwork, prescription evidence, ownership/access records and communications relevant to who controlled the location or item.

What should you send us?

Send the allegation/charge, search record, custody/bail papers, forensic result, prescription evidence if relevant, shared-access information and next date.

FREQUENTLY ASKED QUESTIONS

Questions about this issue

If drugs are found in my house, am I automatically in possession?

No. The prosecution must prove your possession and the required knowledge. Shared access and location can be important.

Does the prosecution have to prove I knew the exact drug?

The statutory knowledge rules are more nuanced than that. The precise facts and section 28 should be analysed in each case.

Can prescription medication be relevant?

Yes, where lawful possession or authority is in issue. The precise controlled-drug classification and prescription evidence should be checked.
