Charged with manufacturing drugs? What the offences are
The Controlled Substances Act 1984 (SA) contains a group of offences about making drugs and the chemicals and equipment used to make them. This guide sets out manufacturing drugs SA law: what manufacture means, when a person takes part, the precursor and equipment offences, how quantity is worked out, penalties and sentencing. It states the law current to 5 November 2026.
The Drug Offences SA guide explains how the drug charges fit together. Selling the finished drug is covered in drug trafficking. Making cannabis resin or oil is covered in manufacturing cannabis resin or oil, and growing cannabis in cultivating cannabis.

What does manufacturing a drug mean?
To manufacture a controlled drug is to undertake any process by which the drug is extracted, produced or refined, or to take part in that process (section 4). Extraction covers pulling a drug out of another substance, production covers making it, and refining covers purifying it.
The Act creates two main manufacturing offences:
| Offence | What must be proved | Section |
|---|---|---|
| Manufacture for sale | Manufacture of the drug, intending to sell any of it or believing another person intends to sell any of it | Section 33 |
| Manufacture | Manufacture of the drug, with no sale element | Section 33J(1) |
Manufacture for sale is graded by quantity in the same three tiers as trafficking. If the prosecution proves that the person manufactured a trafficable quantity, or attempted or conspired to do so, they are presumed to have had the intention or belief about sale, in the absence of proof to the contrary (section 33(4)).
When does a person take part in manufacture?
A person takes part in the process of manufacture if they direct, take or participate in any step in it, or cause a step to be taken (section 4(4)). When done for the purpose of manufacture, the steps include (section 4(6)):
- acquiring, storing, carrying, guarding or concealing equipment, substances or materials used in the process;
- providing or arranging finance; and
- providing or allowing the use of premises.
This is why a manufacturing charge can be laid against people who never handled a chemical. It is also why the purpose of the step matters: the prosecution must prove it was taken for the purpose of manufacture.
A step need not complete the process. In R v Randylle [2006] SASC 318, a five judge Court of Criminal Appeal said the taking-part provisions should not be read narrowly, given the clandestine and mobile character of drug production ([5], [36]). It held that a step can be taken by someone who does not have all the equipment or chemicals, before any chemical reaction, and that acquiring or assembling equipment or consumables can be a step ([43], [47]). Bringing all the equipment and most of the chemicals together at one place, intending to use them there shortly, had gone beyond merely preparatory acts ([48] to [49]).
Randylle was decided under the provisions in force before 2007. The current section 4(4) and (6) describe taking part in similar terms and list acquiring and storing equipment and providing premises as steps.
Preparation is not always a step. Whether conduct is a step in the process or only preparation depends on all the proved circumstances (Randylle [37] to [38], [42] to [44]). The Court left open whether buying a single piece of glassware could be enough ([33], [45]).
Is making drugs for personal use an offence?
Yes. Section 33J(1) makes it an offence to manufacture a controlled drug, whatever the purpose. The maximum for the basic offence is $30,000 or 7 years, or $75,000 or 15 years for a serious drug offender.
The sale element is what separates section 33J(1) from section 33. If the amount made, or being made, is a trafficable quantity, section 33(4) presumes an intention or belief about sale, and the charge can become manufacture for sale. The drug trafficking guide lists the trafficable quantities, such as 2 grams of methylamphetamine.
What are the precursor and equipment offences?
A controlled precursor is a substance the Regulations declare to be one (section 4). The Act also refers to prescribed equipment. The Controlled Substances (Controlled Drugs, Precursors and Plants) Regulations 2014 (SA) list the precursors, the quantities and the equipment.
Four groups of offences deal with them:
- Possession intending to manufacture. Possessing a controlled precursor or prescribed equipment intending to use it to manufacture a controlled drug (section 33J(2)).
- Selling precursors. Selling a controlled precursor, or possessing one intending to sell it, believing the buyer or another person intends to use it to unlawfully manufacture a controlled drug, graded by quantity (section 33A(1) to (3)).
- Making precursors. Manufacturing a precursor intending to make a drug for sale, or intending to sell the precursor while believing it will be used to unlawfully manufacture a drug (section 33A(4) and (5)).
- Prescribed quantities. Possessing or supplying a prescribed quantity of a controlled precursor without reasonable excuse, or a prescribed quantity together with another precursor or prescribed equipment (section 33LB(1) and (2)).
The section 33LB offences have no element of intention to manufacture. The burden of proving a reasonable excuse lies on the person charged (section 33LB(1)). A related offence covers possessing or supplying a document containing instructions for manufacturing a controlled drug without reasonable excuse (section 33LAB).
How is the quantity worked out in a laboratory case?
Quantity decides which section 33 offence is charged. In a laboratory case the drug may never have been finished, so the question is often what the process would have produced.
Manufacture is a process. In R v Vaccaro [2017] SASCFC 10, the commercial quantity charge was particularised as acquiring, storing, carrying and transporting 375 packets of pseudoephedrine medications ([8]). The Full Court said manufacture of methylamphetamine is a process in which a person can take part continuously, intermittently or by a single act, but the facts must establish one manufacture ([41]). The prosecution did not have to prove that more than 100 grams was to be produced in a single batch; several batches may form one offence ([42]).
Complete or incomplete. Because of the extended definition, a section 33(2) offence may be complete, where a commercial quantity was produced, or incomplete, where a step was taken towards producing it. Either way, the process must be one that results, or if completed would result, in a commercial quantity ([43]). The appeal was dismissed ([61] to [62]).
Pure and mixed. Where the Regulations prescribe more than one measure, the one that applies is the one the charge alleges (section 33OA(1)). Since 29 September 2022, a drug or precursor is taken to be contained in a mixture unless it is proved beyond reasonable doubt that it was not, or that it was pure (section 33OA(3)).
Quantity is not a mental element. The prosecution need not prove the person knew the quantity involved (section 33P(2)).
What must the prosecution prove?
The elements depend on the charge, but most manufacturing cases turn on four questions:
| Question | Why it matters |
|---|---|
| Was there manufacture, or a step in it? | The conduct must be a step in the process, not mere preparation (Randylle). |
| Was the step taken for the purpose of manufacture? | Storing goods or lending premises is a step only if done for that purpose (section 4(6)). |
| Did the person know it was a controlled substance? | Knowledge or recklessness that the substance was or was to be a controlled substance must be proved, but not its identity (section 33P(1) and (2)). |
| Was there a sale element? | Required for section 33, and presumed only where a trafficable quantity is involved (section 33(4)). |
In Kingston (a pseudonym) v The Queen [2022] SASCA 90, the Court of Appeal said knowledge or recklessness that a substance is a controlled substance suffices under section 33P, and the accused need not know its identity ([46]).
Possession of precursors, equipment or the drug itself is proved in the same way as any drug possession: knowledge and an intention to control. The drug possession guide explains it.
What is the penalty for manufacturing drugs?
Each maximum depends on whether the person is a serious drug offender and whether the offence is aggravated:
| Offence | Basic offence | Serious drug offender | Aggravated offence |
|---|---|---|---|
| Manufacture of a large commercial quantity for sale (section 33(1)) | $1,000,000 or life | $1,000,000 or life | $1,000,000 or life |
| Manufacture of a commercial quantity for sale (section 33(2)) | $200,000 or 25 years | $500,000 or life | $500,000 or life |
| Manufacture of any quantity for sale (section 33(3)) | $50,000 or 10 years | $75,000 or 15 years | $75,000 or 15 years |
| Manufacture (section 33J(1)) | $30,000 or 7 years | $75,000 or 15 years | $75,000 or 15 years |
| Possessing a precursor or prescribed equipment intending to manufacture (section 33J(2)) | $20,000 or 5 years | $30,000 or 7 years | $30,000 or 7 years |
The precursor offences carry these maximums:
| Offence | Basic offence | Serious drug offender or aggravated |
|---|---|---|
| Selling a large commercial quantity of a precursor for unlawful manufacture (section 33A(1)) | $200,000 or 25 years | $500,000 or life |
| Selling a commercial quantity (section 33A(2)) | $75,000 or 15 years | $200,000 or 25 years |
| Selling any quantity (section 33A(3)) | $50,000 or 10 years | $75,000 or 15 years |
| Manufacturing a precursor (section 33A(4) and (5)) | $50,000 or 10 years | $75,000 or 15 years |
| Prescribed quantity of a precursor without reasonable excuse (section 33LB(1)) | $15,000 or 3 years | $20,000 or 5 years |
| Prescribed quantity with another precursor or prescribed equipment (section 33LB(2)) | $20,000 or 5 years | $30,000 or 7 years |
| Instructions for manufacture without reasonable excuse (section 33LAB) | $10,000 or 2 years | $20,000 or 5 years |
A serious drug offender is a person with the prior drug convictions described in section 4, and an aggravated offence is one connected with a criminal organisation (section 43). The drug trafficking guide explains both.
How are manufacturing offences sentenced?
The court must consider the matters in section 44(1), including the nature and quantity of the drug, the person’s circumstances, and any commercial motive and likely financial gain. For manufacture for sale under section 33, it must also consider whether a child was present (section 44(1)(daa)). All controlled drugs other than cannabis are treated as equally very harmful (section 44(2)).
Danger to the community. In R v Sarandoglou [2010] SASC 190, extracting pseudoephedrine at home caused an explosion and fire. Doyle CJ said home laboratory production of methylamphetamine is part of a broader picture of drug trading with significant adverse social effects ([8]). The risk of injury to innocent bystanders makes general deterrence of considerable importance ([14]).
Deterrence over personal circumstances. In R v Modra [2006] SASC 106, a sophisticated shed laboratory produced ecstasy ([40] to [41]). Perry J said the need for general and personal deterrence in drug sentencing is substantial, so there is less scope to give weight to personal circumstances ([45]).
Both decisions concerned offences under the provisions in force before 2007, but they state sentencing principles that do not depend on those provisions. Modra also treated ecstasy as a mid-range drug ([30] to [31]). Section 44(2) now requires all drugs other than cannabis to be treated as equally very harmful, so this guide does not rely on that part of the reasoning. In R v Young [2016] SASCFC 102, the majority said that rule is limited to the physiological effects of drugs ([43]).
Role. A person who took one step in someone else’s operation is in a different position from the cook or the organiser. The evidence of who did what, and for what reward, is often as important at sentence as at trial.
What happens to a house used as a laboratory?
Property used in an offence can be an instrument of it under the Criminal Assets Confiscation Act 2005 (SA). In Director of Public Prosecutions v George [2008] SASC 330, Doyle CJ, giving the leading judgment in the Full Court, said property is an instrument if it is used in a way that facilitates, assists or contributes to the offence, and that land used as a home can also be an instrument ([62] to [65]). A suburban block whose shed, water and electricity were used for hydroponic cannabis was an instrument ([67] to [78]). Vanstone J took a narrower view of what an instrument is ([167] to [169]).
Prescribed drug offenders. A conviction for manufacturing a commercial or large commercial quantity for sale (section 33(1) or (2)) makes the person a prescribed drug offender, as does a third conviction for a serious drug offence within 10 years in the circumstances section 6A describes. All property the offender owned or effectively controlled on the day of conviction is then forfeited, except protected property such as household contents and personal effects (section 56A). In Donnelly v Director of Public Prosecutions (SA) [2024] SASCA 45, Kourakis CJ described the purpose of the scheme as punishing prescribed drug offenders severely by forfeiture of all their property, however acquired ([13]).
The criminal assets confiscation guide explains restraining orders, deadlines and exclusion applications.
How similar cases tend to play out
Three illustrations of how the manufacturing provisions apply on ordinary facts. They are not predictions. The result depends on the evidence, the person’s role and record, and the court.
Lower range. A university student buys glassware and chemicals online to try to make a small amount of a drug for himself. Police find the parcel at his flat before anything has been made. If the chemicals are a controlled precursor or the glassware is prescribed equipment, the likely charge is possession intending to manufacture under section 33J(2), with a maximum of $20,000 or 5 years. The prosecution must prove the intention to manufacture; there is no sale element.
Middle range. A man lets an acquaintance store boxes in his shed. Police find glassware, residues and receipts for cold and flu tablets bought at many pharmacies. Providing premises and storing equipment are steps in manufacture only if done for that purpose, so his knowledge of what the boxes held is the central issue (section 4(6)). If he knew, Randylle shows that acquiring and assembling equipment can be a step even before any chemical reaction.
Upper range. Two men run a laboratory in a rented suburban house where a young child lives, producing methylamphetamine in batches over several months. If the batches form one process that would produce a commercial quantity, the charge is under section 33(2) (Vaccaro). The child’s presence must be considered at sentence (section 44(1)(daa)), the fire risk makes general deterrence important (Sarandoglou), and on conviction their own property is forfeited under section 56A of the Criminal Assets Confiscation Act 2005.
How we defend a drug manufacturing charge
Manufacturing cases are built on circumstantial evidence: residues, receipts, purchases, phone records and who had access to the site. We test each link the prosecution relies on.
| Stage | What happens | What we do |
|---|---|---|
| Search | Police and forensic chemists examine the site and seize equipment and chemicals. | Advise before any interview, and test the warrant or search power relied on. |
| Charge | The charge alleges manufacture, taking part, or a precursor or equipment offence. | Check the particulars: which step, which purpose, which quantity. |
| Expert evidence | Chemists give evidence about the process, the yield and the substances found. | Test the theoretical yield and whether one process was proved (Vaccaro). |
| Negotiation | The prosecution may accept a lesser quantity or a section 33J offence instead of section 33. | Put the gaps in the evidence of purpose, knowledge and quantity to the prosecution. |
| Trial or plea | A contested trial, or a plea of guilty. | Run the defence at trial, or present role, circumstances and rehabilitation at sentence. |
| Property | Restraining orders and forfeiture. | Advise on exclusion applications and their deadlines. |
We cannot promise a particular result, and no lawyer can. We can make sure the prosecution proves every step it alleges.

Case notes
R v Randylle [2006] SASC 318
The appellant was convicted of taking part in the manufacture of methylamphetamine under the provisions then in force. Doyle CJ, with the other four judges agreeing, said the taking-part provisions are not to be read narrowly ([5], [36]). His Honour held that a step can be taken by someone without all the equipment or chemicals and before any chemical reaction, and that acquiring or assembling equipment or consumables can be a step ([43], [47]). Bringing together the equipment and most of the chemicals, intending to use them there shortly, was such a step ([48] to [49]). The appeal was dismissed ([52] to [56]).
R v Vaccaro [2017] SASCFC 10
The charge of manufacturing a commercial quantity of methylamphetamine for sale was particularised as acquiring, storing, carrying and transporting 375 packets of pseudoephedrine medications ([8]). The Full Court said manufacture is a process in which a person can take part continuously, intermittently or by a single act, provided the facts establish one manufacture ([41]), and that several batches may form one offence ([42]). Because of the extended definition, a section 33(2) offence may be complete or incomplete, but the process must be one that results, or if completed would result, in a commercial quantity ([43]). The appeal was dismissed ([61] to [62]).
R v Sarandoglou [2010] SASC 190
Extraction of pseudoephedrine at the offender’s home caused an explosion and fire ([4]). Doyle CJ said home laboratory production of methylamphetamine has significant adverse social effects ([8]) and that the risk to bystanders makes general deterrence of considerable importance ([14]). His Honour described the 15-month head sentence as more than merciful ([16]). The appeal against sentence was dismissed by majority ([25] to [26]); Kourakis J would have reduced the non-parole period ([44]).
R v Modra [2006] SASC 106
The appellant produced ecstasy and MDA in a sophisticated shed laboratory ([40] to [41]). Perry J, with Duggan and Anderson JJ agreeing, said the need for general and personal deterrence in drug sentencing is substantial, leaving less scope for weight to be given to personal circumstances ([45]). The appeal against sentence was dismissed ([63] to [65]).
Kingston (a pseudonym) v The Queen [2022] SASCA 90
The Court of Appeal said that under section 33P, knowledge or recklessness that a substance is a controlled substance suffices, without knowledge of its identity ([46]). The appeals, against convictions for attempted trafficking in butanediol, were allowed on other grounds ([92]).
R v Young [2016] SASCFC 102
In a trafficking appeal, the majority said section 44 does not stop courts distinguishing between drugs on grounds other than their physiological effects ([43]). The prosecution appeal was allowed and the respondent resentenced ([73] to [79]).
Director of Public Prosecutions v George [2008] SASC 330
Hydroponic cannabis was grown in a large shed on a suburban block, using the land’s water and electricity. Doyle CJ, giving the leading judgment, said an instrument is property used in a way that facilitates, assists or contributes to the offence, with no need for a substantial connection or causal link, and that land used as a home can be an instrument ([62] to [65], [67] to [78]). Vanstone J took a narrower view of instrument ([167] to [169]). The appeal was allowed, the order excluding the land was set aside, and other applications were remitted; Vanstone and White JJ agreed with those orders ([117] to [123], [175], [252]).
Donnelly v Director of Public Prosecutions (SA) [2024] SASCA 45
Kourakis CJ, with Doyle JA agreeing, said the manifest purpose of section 56A is to punish prescribed drug offenders severely by forfeiting all their property, however acquired, and to deter serious drug offending ([13]). The conditions for prescribed drug offender status are tested at the moment of conviction ([15]), and all of the appellant’s property on that day was forfeited ([23]). The declaration was varied to except a bank’s registered mortgage interest; the appeal was otherwise dismissed ([24] to [25]). Blue AJA dissented ([53] to [54]).
Frequently asked questions
What does manufacturing drugs mean in SA?
It means any process by which a controlled drug is extracted, produced or refined, or taking part in that process (section 4 of the Controlled Substances Act 1984). Taking part includes steps such as acquiring or storing equipment, providing finance or providing premises, when done for the purpose of manufacture.
Is making drugs for personal use an offence?
Yes. Manufacturing a controlled drug is an offence even without any intention to sell, with a maximum of $30,000 or 7 years for the basic offence (section 33J(1)). If a trafficable quantity is made, an intention or belief about sale is presumed (section 33(4)).
What is the penalty for manufacturing drugs in SA?
It ranges from $30,000 or 7 years for manufacture without a sale element to $1,000,000 or life for manufacturing a large commercial quantity for sale (sections 33 and 33J). Serious drug offenders and aggravated offences carry higher maximums.
Can I be charged if no drugs were made?
Yes. Taking a step in the process can be enough, and a commercial quantity offence can be incomplete if the process would have produced that quantity. Possessing precursors or prescribed equipment can also be an offence in its own right (sections 33J(2) and 33LB).
What does taking part in manufacture mean?
It means directing, taking or participating in any step in the process, or causing a step to be taken (section 4(4)). The step must be done for the purpose of manufacture (section 4(6)).
What is a controlled precursor?
A substance the Regulations declare to be a controlled precursor (section 4). Selling, making or possessing precursors can be an offence, depending on the quantity and the person’s intention or belief (sections 33A, 33J(2) and 33LB).
Is it an offence to have instructions for making drugs?
Yes, unless the person has a reasonable excuse, which they must prove. Possessing or supplying a document containing instructions for manufacturing a controlled drug carries up to $10,000 or 2 years for the basic offence (section 33LAB).
How is the quantity worked out when the drug was not finished?
The question is what the process would have produced. A section 33(2) offence can be incomplete if the process, once completed, would have produced a commercial quantity, and several batches can form one offence (R v Vaccaro).
Does a child living at the property make a difference?
Yes. For manufacture for sale, the sentencing court must consider whether a child was present (section 44(1)(daa)). Courts also treat the risk of fire and explosion to bystanders as a reason for general deterrence.
Can the house be taken if it was used as a laboratory?
It can. Property used to facilitate an offence can be an instrument liable to restraint and forfeiture, and a home can be an instrument. A conviction for manufacturing a commercial quantity for sale also forfeits all the offender’s property other than protected property (section 56A of the Criminal Assets Confiscation Act 2005).
Do I need a lawyer for a drug manufacturing charge?
Manufacturing charges turn on technical evidence about chemistry, yield and purpose, and they put property at risk from the first day. We can advise on the charge and the property at once. Call (08) 7094 2021.
