Drug Offences in Mauritius Under the Dangerous Drugs Act 2000

The Dangerous Drugs Act 2000 is Mauritius’ principal statute for controlling dangerous drugs and prosecuting drug offences. It separates unlawful consumption and possession from supply, dealing, importation, manufacture and related conduct; the substance, alleged activity, custody or control, purpose and evidence determine the charge. A person should therefore work from the charge sheet and current legislation, not from a generic description such as “a drug case”.

Structure of the Dangerous Drugs Act 2000

The Dangerous Drugs Act is Act 41 of 2000. Its early Parts classify controlled substances and regulate authorised cultivation, import, export, prescription, supply and possession. Part III then creates offences, investigative powers, evidential rules and sentencing consequences. The First, Second and Third Schedules identify dangerous drugs, while other schedules address precursors and procedural matters.

The Act has been amended since 2000, including by the Dangerous Drugs (Amendment) Act 2022, only specified parts of which were proclaimed in December 2022. This matters because a later amendment, a medicinal scheme or a rule applying to one scheduled substance must not be generalised to every drug. The Act also addresses driving after unlawful dangerous-drug use; alcohol-based driving offences are dealt with separately in our guide to drink driving in Mauritius.

Possession, consumption and supply offences

Section 21 prohibits possession unless the person is authorised under the Act. Section 34 makes it an offence unlawfully to consume or self-administer a dangerous drug and also covers unlawful possession, purchase, an offer to purchase or transport. Possession is therefore not confined to an item found in a pocket: the statutory definition extends to custody or control and, in defined circumstances, drugs held by another person or kept in controlled premises or a vehicle.

Supply allegations occupy different provisions. Section 35 concerns offering, selling or distributing a drug for another person’s personal consumption. Section 30 covers a much broader group of drug-dealing activities, including import or export, production, sale, delivery and transport, as well as possession or purchase for the purpose of such an activity. The dividing issue may be alleged purpose rather than physical possession alone; the practical distinction is developed in Drug Trafficking or Possession?

Presumptions and how they shift the burden

The Act does not contain one all-purpose presumption that converts every drug discovery into trafficking. It contains several targeted rules. Section 21 defines circumstances in which a person is deemed to possess a drug through custody or control. Section 46 places on a person the burden of proving lawful authorisation when that specific question arises. Section 50 creates rebuttable premises-related presumptions after specified findings on a warranted search.

A different provision, section 41, contains a deeming rule concerning “drug trafficker” status by reference to the statutory street-value test. That is not a universal weight threshold, and it should not be described as a rule that any stated number of grams automatically proves sale. Before any targeted burden or deeming rule can operate, its own gateway facts still have to be established. Counsel should identify the precise rule invoked, the facts said to trigger it and its effect on the live charge.

Quantity, purity and expert evidence

Quantity may affect how the prosecution characterises the alleged purpose, the asserted street value and the eventual sentencing position, but it does not replace proof of the charged conduct. Packaging, scales, communications, cash, movements and the location of the item may be put forward as surrounding evidence. Each item must be proved and assessed in context; an inference is not made reliable merely by listing several suspicious features.

Section 58 sets safeguards for seized drugs. It provides for sealing in the accused’s presence, or before two witnesses if that is impossible, numbering and labelling the items, recording the discovery and weight, safe storage and a written record of later movement. It also contemplates an expert report on nature, composition and active principles. The defence should compare the seizure report, labels, seals, movement record, weighing material and laboratory result. Our guide to evidence and witnesses in Mauritian courts explains the wider trial setting.

Penalties on conviction

There is no single penalty for “drug possession”. The statutory range changes with the offence, the drug’s Schedule, whether dealing is proved, any prescribed aggravating circumstance and the court hearing the case. A section 30 dealing conviction is treated much more seriously than unlawful use under section 34. Section 41 identifies aggravating circumstances such as violence or a weapon, involvement of a child, particular protected locations and a relevant prior drug conviction.

For unlawful use under section 34, the Act permits the court, where it considers this appropriate and subject to the statutory conditions, to consider treatment, education, aftercare, rehabilitation or social reintegration instead of imprisonment. That route is not an automatic entitlement. The Act also provides for forfeiture of the drugs and connected articles or money, and may permit forfeiture of a vehicle used for unlawful transport or distribution. If alleged violence produces a separate charge, read the distinct guide to assault, wounds and blows.

Defences and mitigation

A defence begins with the exact averments. Relevant questions may include whether the substance was proved to be the scheduled drug alleged; whether the accused had the custody or control required by section 21; whether lawful authorisation is in issue; whether a dealing purpose is proved under section 30; and whether search, seizure and expert evidence support the prosecution account. Section 30 expressly permits an alternative finding of simple possession under section 34 where dealing purpose is not proved, so defeating the more serious purpose allegation does not necessarily end the case.

Mitigation is different from a defence and is prepared only in a manner consistent with the plea and findings. Verified medical material, treatment engagement, personal circumstances, role and other admissible information may be relevant, but unsupported claims can damage credibility. Do not alter messages, discard packaging, approach a prosecution witness or reconstruct an account with other suspects. Preserve original material and obtain advice before making consequential decisions.

Bail and pre-trial issues in drug cases

Bail is determined under the Bail Act 1999 and the applicable constitutional framework, with attention to the actual grounds advanced against release and whether workable conditions address them. A serious drug charge may produce objections based on attendance, interference, evidence or alleged further offending, but the offence label alone is not a complete bail analysis. A proposal should use a verifiable address, accurate information about ties and sureties, and conditions the accused can genuinely follow.

The Dangerous Drugs Act also contains a special police-custody provision for specified dealing allegations. Any restriction under it must satisfy its own statutory conditions and be assessed alongside constitutional safeguards. At the pre-trial stage, obtain the charge, custody documents, search warrant where applicable, seizure report, laboratory material and bail papers. Record what occurred while memory is fresh, without contacting witnesses or interfering with evidence.
