Weed in South Africa is decriminalised for private adult use. Selling and public smoking are still criminal offences under the Cannabis for Private Purposes Act, 2024. Cannabis is also the substance most often listed at admission in local rehab facilities. The facts below cover what counts as legal, how the market works on the ground and the addiction risks behind the headline numbers.

Is weed legal in South Africa?
Personal, private adult use of cannabis is no longer a criminal offence in South Africa. The Cannabis for Private Purposes Act, signed in May 2024, removed dagga from the country’s list of outlawed narcotics for adults using it in private.
Commercial sale stays prohibited outside the licensed medical pathway, but the picture on the ground is messier. Cannabis clubs and dispensaries have opened across Cape Town and other metros, operating as private member collectives that “share” cannabis among members rather than sell it commercially. SAHPRA and the SAPS still treat unlicensed retail as illegal, and several high-profile dispensaries have been raided since 2020.
Draft regulations published in February 2026 propose a 750-gram personal possession cap and a five-plant home-grow limit. A commercial licensing framework is targeted for the end of the 2025/26 financial year. Supplying cannabis to anyone under 18 remains a clear criminal offence regardless of any of the above.

Weed is the reason for the majority of people in rehab treatment for addiction
Cannabis is the substance most often cited at admission to South African addiction treatment centres, and the share is climbing. A 2026 analysis of SACENDU treatment data found that cannabis treatment demand among adolescents and young adults rose from 43.4% in 2020 to 56.2% in 2023. Across most provinces, between 60% and 72% of clients under 20 list cannabis as their primary substance.
Who uses weed daily in South Africa?
A 2024 synthesis of five national household surveys covering more than 89 000 South Africans found that past-three-month cannabis use rose from 1.5% in 2002 to 7.8% in 2017. Demographic data from the same surveys shows that daily cannabis users are more likely than non-users to:
- Be male: men in South Africa are about 11 times more likely than women to be daily weed users.
- Have a Grade 8-11 level of education: the study authors describe this as “concerning” because it shows that increasing cannabis use is associated with an increasing risk of leaving school without qualifications. Non-users were more likely to have a higher educational qualification.
- Never have been married: unmarried people are about three times more likely to be daily marijuana users than their married counterparts.
- Have an alcohol use disorder, the medical term for alcohol addiction.
- Use other drugs: people who used other drugs were 16 times more likely to be daily weed users compared to those who did not use other narcotics.
- Live in an urban area: a much higher percentage of urban dwellers used cannabis daily than those residing in rural areas.
Marijuana use is common in the country
Past-three-month cannabis use among South Africans aged 15 and over has risen from 1.5% in 2002 to 7.8% in 2017, the most recent year for which national household data is published. About 2.8% of respondents reported daily use. The authors put the high prevalence down to accessibility and price. The 2024 decriminalisation has done little to change either.
Cannabis is very cheap in South Africa
Cannabis sells across two parallel markets in South Africa. Outdoor-grown street dagga is widely available for R10 to R20 per gram in most metros. Indoor-grown, higher-THC products are priced closer to R150 to R200 per gram. That indoor format is the one most often associated with the rise in cannabis use disorder cases reported by treatment centres.
South Africa is a huge exporter of weed
South Africa’s cannabis sector has been valued at around R28 billion across formal and informal supply, with the national cannabis master plan published in 2021 projecting growth as licensing opens up. The country also ranks among the world’s largest illicit cannabis producers, with UNODC data estimating around 2 500 tons grown each year. Most of that volume sits outside the licensed medical and hemp markets, which is why street prices have stayed low.
When weed use becomes a weed problem
Cannabis use disorder is the medical term for cannabis dependence. It affects roughly one in ten regular users and rises to one in six for people who started smoking before age 18.
The pattern looks like any other addiction. The user loses control over how often they use. Attempts to cut down keep failing. Daily life starts to suffer.

Decriminalisation has not changed the clinical picture. Cannabis still drives more addiction-treatment admissions than any other substance in South Africa. Higher-THC indoor products are now the norm in the local market. If daily use is the new baseline at home, or if going without cannabis brings irritability and sleep disruption, marijuana addiction treatment is the next step.
