6 Things Cannabis Users Still Get Wrong About the Law

South Africa’s Cannabis law is often described as “unclear.”
In truth, many of the rights are clear — they’re just poorly understood, unevenly applied, and frequently ignored by authorities.

Here are six common misunderstandings that continue to put Cannabis users at risk.

1. “Cannabis is fully legal in South Africa”

Cannabis is not fully legal.

The Constitutional Court ruled that adults may use, possess, and cultivate cannabis for personal use in private. Commercial trade and public sales remain unlawful.

This means cannabis is partially decriminalised, not broadly legalised.

Understanding the scope of that protection is essential.

2. “Private space only means your home”

This is one of the most widespread misunderstandings — and it’s incorrect.

The Constitutional Court recognised that privacy belongs to the person, not only to homeowners. A “private space” can include:

  • Bags
  • Pockets
  • Shoes
  • Vehicles
  • Personal belongings, including those of homeless people

In law, this means that Cannabis carried on your person can still fall within the protection of privacy.

The problem is not that the law is restrictive — it’s that police often fail to respect or understand this principle, leading to unlawful searches and arrests.

3. “Police are allowed to confiscate my Cannabis”

They generally are not.

Since the 2018 ruling, SAPS has issued directives instructing officers not to seize Cannabis that is possessed for personal use in a private space.

Confiscation still happens — but when it does, it is often:

  • Unlawful
  • Contrary to internal SAPS guidance
  • A result of ignorance or overreach

Many people comply out of fear or uncertainty, not because the seizure is legal.

4. “I can be fired just for testing positive for THC”

This is false.

South African labour law now clearly distinguishes between:

  • Presence of THC in the body
  • Actual intoxication or impairment at work

Courts have recognised that Cannabis metabolites can remain in a person’s system for weeks, long after any intoxicating effect has passed.

An employer must prove:

  • Impairment
  • Incapacity
  • Or a real safety risk

A positive test alone is not sufficient grounds for dismissal.

5.  “Legal reform fixed the harm of prohibition”

It didn’t.

Thousands of people still live with:

  • Criminal records
  • Lost employment opportunities
  • Travel restrictions
  • Long-term stigma

Expungement is possible in some cases, but it is not automatic, and many people remain excluded from the legal cannabis economy that now exists.

Legal reform without repair leaves historic injustice intact.

6.  “There is a legal limit on how many Cannabis plants I may grow”

This is one of the most widely repeated — and incorrect — beliefs about Cannabis law in South Africa.

Despite claims circulating online and even being repeated by police and officials, there is no fixed plant limit set out in the Act signed by the President in May 2024.

You will often hear numbers like:

  • “Four plants per adult”
  • “Eight plants per household”
  • “One flowering plant at a time”

These figures do not appear in the Act.

What the law regulates is purpose, not plant count.

Adults may cultivate Cannabis for personal use in private. The law does not reduce legality to a numerical formula. Instead, the question is whether cultivation is:

  • For personal use, or
  • For distribution or commercial purposes

Plant counting has become a shortcut used by authorities to justify arrests or seizures, even though quantity alone is not determinative in law.

This misconception persists because:

  • Older draft bills mentioned plant numbers that were never enacted
  • Police training has not kept pace with the law
  • People mistake informal guidelines for binding rules

The result is unnecessary fear — and unlawful interference — based on limits that do not legally exist.

Until the law explicitly sets numerical thresholds, plant numbers must be assessed in context, not treated as automatic evidence of wrongdoing.

Understanding cannabis law means reading what is actually written, not what is repeated.

When it comes to plant limits, the law is clear — even if the rumours are not.

WHY THIS STILL MATTERS

The biggest risk facing Cannabis users today is not the law — it is misinformation and misapplication.

People are still:

  • Arrested unlawfully
  • Having property seized without legal basis
  • Disciplined at work using outdated policies

Knowing your rights is essential.
So is recognising when those rights are being violated.

THE REALITY

South Africa’s Cannabis framework is progressive on paper and fragile in practice.

Until education, policing, and labour policy catch up with the courts, vigilance remains necessary — not because the law is against users, but because it is not consistently enforced in their favour.

The result is unnecessary fear — and unlawful interference — based on limits that do not legally exist.

Until and IF the law explicitly sets numerical thresholds in future, plant numbers must be assessed in context, not treated as automatic evidence of wrongdoing.

Understanding Cannabis law means reading what is actually written, not what is repeated.

When it comes to plant limits, the law is clear — even if the rumours are not.
