Cannabis Personal Cultivation Limits in South Africa
Personal cultivation is decriminalized under Prince; statutory limits pending commencement.
This article is general information, not legal advice. Laws change; check current rules with official sources or a lawyer.
South Africa decriminalized private adult cannabis use in 2018, but has no official plant or quantity limits in force yet. The 'four plants' figure you see online is folklore, not law. A new Act passed in 2024, but its operative limits haven't been proclaimed yet. Until then, police and courts decide case-by-case whether your grow is personal use or dealing. Check the Government Gazette for updates before you plant.
Legal basis: the Prince judgment
On 18 September 2018, the Constitutional Court of South Africa handed down Minister of Justice and Constitutional Development v Prince ZACC 30, which declared unconstitutional the criminal prohibitions on the use, possession and cultivation of cannabis by an adult, in private, for personal consumption Strong evidence[1]. The Court did not set numeric limits. Instead, it read words into the Drugs and Drug Trafficking Act 140 of 1992 and the Medicines and Related Substances Act 101 of 1965 so that the prohibitions did not apply to private adult use, and gave Parliament 24 months to enact corrective legislation.
The judgment left it to police and prosecutors — and ultimately courts — to assess, case by case, whether a given quantity was consistent with personal use or indicative of dealing Weak / limited[1]. This is why, between 2018 and 2024, there is no official 'four plants per adult' rule in South African law, despite that number circulating widely online Anecdote.
The Cannabis for Private Purposes Act, 2024
President Ramaphosa signed the Cannabis for Private Purposes Act 7 of 2024 (CfPPA) into law on 28 May 2024 Strong evidence[2]. The Act is intended to give effect to the Prince judgment by creating a specific statutory framework for adult private cultivation, possession and use, and by expunging certain past convictions.
Crucially, most of the Act's substantive provisions do not commence on signature — they come into force on a date fixed by presidential proclamation in the Government Gazette Strong evidence[2]. As of 1 November 2026, the bulk of those provisions, including the schedules that will contain the numerical quantity limits, have not yet been proclaimed in force. Readers should check the current Government Gazette or a South African legal database (SAFLII, LexisNexis, Juta) for the latest commencement notice before relying on any specific number.
What the Act provides for quantities
The CfPPA is structured around 'prescribed quantities' for (a) cultivation, (b) possession in a private place, and (c) possession in a public place, distinguishing between one adult and multiple adults in a dwelling Strong evidence[2]. The Act refers to these quantities being set out in a Schedule. The Schedule attached to the Bill as passed listed specific plant counts and dried cannabis weights, but the operative Schedule can be amended by the Minister of Justice by notice in the Gazette Strong evidence[2].
Because those numbers may change on commencement, and because commencement has not yet occurred, this article does not list specific plant or weight figures. Publishing a number that may be incorrect is exactly the kind of misinformation Weedpedia tries to avoid. Once the CfPPA Schedule is proclaimed in force, readers should consult the Government Gazette notice for the authoritative figures.
What remains clearly illegal
Regardless of the CfPPA's commencement status, several things remain unlawful in South Africa:
- Dealing in cannabis — sale, supply, or offering for sale to another person, outside a licensed medicinal or hemp framework Strong evidence[1][2].
- Public consumption — smoking or consuming cannabis in a public place, including in a vehicle on a public road Strong evidence[2].
- Use or possession by children, and supply to a child, which the CfPPA treats as an aggravated offence Strong evidence[2].
- Cultivation or possession that is not for personal use — the personal-use qualifier from Prince still governs conduct Strong evidence[1].
- Driving under the influence, under the National Road Traffic Act 93 of 1996 Strong evidence[3].
Commercial cultivation and sale of cannabis for recreational purposes is not legalised by the CfPPA. A separate licensing regime exists for medicinal cannabis under the South African Health Products Regulatory Authority (SAHPRA) Strong evidence, and industrial hemp is regulated under permits issued by the Department of Agriculture.
Practical enforcement reality
Since 2018, South African Police Service practice has varied widely: some private growers have been left alone, others have been arrested and had plants seized, particularly where quantities were large or where neighbours complained Weak / limited. Courts have generally followed Prince in dismissing charges once it is established that cultivation was private and for personal use, but the burden of demonstrating that falls on the accused in practical terms Weak / limited.
Until the CfPPA's Schedule is in force, there is no bright-line 'safe' number of plants. A grower who keeps cultivation strictly indoors or in a private garden not visible to the public, at a scale consistent with personal consumption, and who does not sell or share commercially, is operating within the Prince framework. However, police discretion and prosecutorial judgment remain significant variables.
Not legal advice
This article is informational only and is not legal advice. South African cannabis law is in a live transition between the Prince judgment framework and the not-yet-fully-commenced Cannabis for Private Purposes Act. If you need to rely on the law — for example because you are facing a charge, planning a grow, or building a business — consult a South African attorney and check the current text of the CfPPA and any commencement proclamations in the Government Gazette.
Last verified: 1 November 2026. Readers finding this article later should assume the Schedule and commencement position may have changed.
