How much cannabis can an adult legally possess in South Africa? Is there a legal limit of 750 grams, or can adults grow five cannabis plants at home without breaking the law?
The answer depends on the distinction between current legal protections and proposed cannabis regulations.
Although South African law protects certain forms of private adult cannabis use and cultivation, there is still no operative statutory limit expressed as a specific number of grams or plants under the legal position described here.
The widely reported figures of 750 grams of cannabis and five plants come from proposed regulations, not rules that have come into force.
How Much Cannabis Is Legal in South Africa?
There is currently no operative statutory gram limit or plant limit that automatically determines whether an adult’s private cannabis possession or cultivation is lawful.
The Constitutional Court’s 2018 judgment established protection for private adult use and cultivation, while leaving Parliament to determine the appropriate quantities.
The following table summarises the position described as of 17 October 2026.
| Cannabis activity | Current legal position |
|---|---|
| Private cannabis use by adults | Protected in qualifying private circumstances |
| Possession for personal consumption in private | Protected in qualifying circumstances |
| Growing cannabis at home for personal use | Protected in qualifying private circumstances |
| Possessing exactly 750 grams | Not automatically unlawful solely because of that quantity under a statutory 750g limit; context still matters |
| Growing five plants | Not a universally established statutory safe limit |
| Selling cannabis commercially | Not generally authorised by the private use protection |
| Dealing in cannabis | Remains subject to criminal law |
Important: The absence of a fixed statutory quantity does not mean that every amount of cannabis is automatically legal.
The circumstances, purpose and evidence surrounding possession or cultivation may matter.
What Did the Constitutional Court Decide About Cannabis?
The starting point for understanding South Africa’s cannabis laws is the Constitutional Court’s judgment in Minister of Justice and Constitutional Development v Prince and related matters, delivered on 18 September 2018.
The Court found that criminalising an adult’s use or possession of cannabis in private for personal consumption, and cultivation in private for that purpose, unjustifiably limited the constitutional right to privacy.
The judgment resulted in protection for qualifying private adult cannabis activities.
What does the 2018 judgment allow?
In general, the judgment protects adults who:
- Use cannabis in private for their own personal consumption.
- Possess cannabis in private for personal consumption.
- Cultivate cannabis in private for personal consumption.
These protections are not a general legalisation of cannabis. They do not establish an unrestricted right to use cannabis anywhere, supply it commercially or sell it to other people.
The Court also did not prescribe a definitive quantity of cannabis that every adult may possess. Instead, it left the development of a legislative framework, including appropriate quantity rules, to Parliament.
Does the judgment mean adults can possess unlimited cannabis?
No. This is one of the most important distinctions in the debate about cannabis possession limits in South Africa.
The judgment did not establish an unlimited legal entitlement. The question of whether a particular quantity is genuinely intended for personal consumption may depend on the facts of a case.
For example, a person’s circumstances, the way cannabis is stored, evidence of distribution and other relevant facts could affect how authorities or a court assess the situation.
There is therefore a difference between saying that no fixed statutory quantity limit is in force and claiming that any quantity is automatically lawful.
Is the Cannabis for Private Purposes Act in Force?
The Cannabis for Private Purposes Act 7 of 2024 is a central part of South Africa’s attempt to establish a statutory framework for private adult cannabis use.
The Act received presidential assent on 28 May 2024. However, under the legal status position described as of 17 October 2026, its commencement has not been proclaimed.
This distinction matters because presidential assent and commencement are separate legal steps.
What does that mean in practice?
An Act can be signed into law but remain inoperative until its commencement date or proclamation takes effect, where the legislation requires one.
If the Cannabis for Private Purposes Act has not commenced, its provisions cannot simply be treated as operative offences or quantity limits.
Consequently, the Act’s existence does not by itself establish a current legal maximum for personal cannabis possession or the number of plants an adult may grow.
Anyone relying on the Act should check the latest official commencement proclamation and Government Gazette rather than relying only on the date of assent.
Are 750 Grams of Cannabis and Five Plants Legal Limits?
The figures of 750 grams and five cannabis plants have attracted considerable public attention.
However, the figures described here come from draft regulations published for public comment in February 2026.
They should not be confused with enforceable limits.
What do the proposed regulations say?
The proposals reportedly include:
- A maximum of 750 grams for possession or transport in a day.
- A maximum of five cannabis plants for private cultivation.
These proposals were intended to help establish clearer quantity rules for private adult cannabis activity.
However, a proposal does not become binding law simply because a government department publishes it for comment.
The applicable legislative and approval procedures must be completed, followed by the required final publication or commencement steps.
Under the status described in this article, the proposals have not completed those steps and are not operative limits.
Can an adult legally grow five plants today?
Five plants should not be treated as a guaranteed legal allowance or a definitive ceiling.
The relevant question remains whether the cultivation falls within the protection for private cultivation for personal consumption, alongside any other applicable law.
The proposed plant limit does not independently determine the outcome.
Likewise, growing six plants does not automatically establish criminal liability merely because a draft proposal mentions five!
The actual legal position and circumstances must be assessed.
Can an adult possess more than 750 grams?
The same principle applies to possession.
The proposed 750 gram figure is not an operative statutory limit under the legal status position discussed here.
Possessing more than that amount does not, by itself, establish that the person has committed an offence under a statutory 750 gram rule that has not come into force.
Nevertheless, a substantial quantity may attract scrutiny, particularly where there is evidence suggesting supply, distribution or commercial dealing.
The key point: Neither 750 grams nor five plants should be presented as a confirmed legal allowance or an enforceable statutory maximum without checking for a subsequent change in the law.
