What is drug manufacture?
Drug Misuse and Trafficking Act 1985 (NSW), s 24: a person who manufactures or produces, or who knowingly takes part in the manufacture or production of, a prohibited drug is guilty of an offence. "Manufacture" includes the process of extracting or refining the drug.
The offence covers the whole process — synthesising, extracting, refining — and any step in it. There is no requirement that the process was finished or that usable drug was actually produced: taking part in the process is the offence.
That phrase, "knowingly takes part", is the reach of this charge. Under the Act, taking part includes taking or participating in any step of the process, providing or arranging finance for it, and providing the premises in which any step occurs. The person who rents the garage, buys the glassware, sources the chemicals or drives the equipment can face the same charge as the cook. What the prosecution must prove for each of them is knowledge — that they knew what the process was — and that contest is where many of these cases are actually decided.
Quantity tiers and penalties — mirroring supply
Manufacture uses the same Schedule 1 quantity thresholds as supply, and the tier alleged sets the maximum:
- Less than commercial quantity — maximum 15 years' imprisonment and/or a fine of $220,000 (2,000 penalty units); smaller matters can remain in the Local Court, where the sentencing cap is 2 years;
- Commercial quantity — maximum 20 years' imprisonment and/or a fine of $385,000 (3,500 penalty units), with a standard non-parole period of 10 years;
- Large commercial quantity — maximum life imprisonment and/or a fine of $550,000 (5,000 penalty units), with a standard non-parole period of 15 years.
For methylamphetamine — the drug in most NSW manufacture prosecutions — the commercial quantity is 250 grams and the large commercial quantity 1 kilogram. As with supply, commercial-quantity manufacture is a show-cause offence under the Bail Act 2013, so the bail position starts against you and needs to be prepared, not improvised.
The aggravation: exposing a child to the process
Where the offence is committed in circumstances in which a child under 16 was exposed to the manufacturing process — or to substances stored for use in it — the maximum penalties increase: from 15 to 18 years below the commercial quantity, and from 20 to 25 years at the commercial quantity. Courts treat the aggravated form with particular severity because of the toxicity and volatility of the process itself.
Precursor offences — charged before anything is made
Drug Misuse and Trafficking Act 1985 (NSW), s 24A: a person who has possession of a precursor intended by the person for use in the manufacture or production of a prohibited drug is guilty of an offence. Maximum penalty: 10 years' imprisonment.
The Act criminalises the supply chain, not just the laboratory. Possessing a precursor chemical — pseudoephedrine is the familiar example — intended for use in manufacture carries up to 10 years, with no completed or even commenced manufacture required. Related offences cover supplying precursors and possessing drug-manufacture apparatus.
The contested element is almost always intention. Many precursors and much of the equipment have entirely legitimate uses, and the prosecution must prove the unlawful purpose — usually by inference from quantity, combination, concealment and communications. Inferences can be tested, and alternative explanations put; this is precisely the territory where early advice changes the shape of a case.
Clan-lab prosecutions — the evidence, and where it is tested
A clandestine-laboratory brief looks formidable: forensic chemists, photographs of equipment, chemical inventories, fingerprints and DNA, telephone records. It is also a brief with recurring pressure points:
- Theoretical yield — where little or no finished drug is found, the alleged quantity is often a chemist's calculation of what the precursors could have produced. Yield calculations rest on assumptions about method and efficiency that can be — and are — challenged by competing expert evidence, and the tier of the charge can turn on them;
- What stage the process reached — whether what was found is manufacture, an attempt, or preparation is a real legal question, not a given;
- Presence versus participation — living at or visiting premises where a lab operates is not, by itself, taking part in manufacture. The prosecution must prove your knowledge and your act of participation;
- Continuity and contamination — clan-lab scenes are processed as hazardous sites; sampling, handling and the chain from scene to certificate are all examinable;
- The search itself — warrants and their execution are tested, and unlawfully obtained evidence can be excluded under s 138 of the Evidence Act 1995.
The defence task is to refuse the brief's first impression and test it expert against expert, element by element.
How Lenz Legal approaches manufacture charges
Dean Lenz has defended drug manufacture matters for more than twenty years. The approach is methodical and starts early: secure the bail position, obtain the complete brief — including the chemist's working papers behind any yield calculation, not just the certificate — and test the quantity tier first, because the tier drives the maximum, the court and the realistic outcome. Where the case against participation is thin, that is run; where knowledge is the real issue, it is confronted directly.
Where the realistic course is a plea, the work turns to the agreed facts — the stage the process reached, the role played, the quantity properly proved — and a subjective case built for the court. Roles in manufacture matters span an enormous range, and sentencing reflects that. Every matter turns on its own facts.
If premises connected to you have been searched, or police have asked you to come in over a suspected lab, get advice before any interview. Explanations about what you knew, offered without advice, are where these cases are most often decided against people.
Drug manufacture — your questions answered
What counts as manufacturing a drug?
Making or producing a prohibited drug, and any step in that process — including extracting and refining. Knowingly taking part is the same offence, which reaches people who provide premises, finance, equipment or transport for the process, provided the prosecution can prove they knew what it was.
What is the penalty for drug manufacture in NSW?
Below the commercial quantity, up to 15 years' imprisonment and/or a $220,000 fine (2,000 penalty units); at commercial quantity, 20 years with a 10-year standard non-parole period; at large commercial quantity, life imprisonment. Exposing a child under 16 to the process raises the maximums to 18 and 25 years respectively.
Is possessing precursor chemicals an offence?
Yes — possession of a precursor intended for use in manufacture carries up to 10 years under s 24A, with no completed manufacture required. Intention is the contested element: many precursors have legitimate uses, and the unlawful purpose must be proved, usually by inference. Inferences can be tested.
Can a manufacture charge be defended?
Yes. The process, your knowing participation and the quantity tier must each be proved, and each is contestable — particularly theoretical-yield calculations and the line between presence and participation. Which issue has real prospects is a judgement made on the full brief. Every matter turns on its own facts.
