The ruling came on Tuesday after a provincial high court in 2017 found out that the use of cannabis in private space should be allowed.
He says the users of alcohol and tobacco are allowed to use these substances however they wish.
These are all popular misconceptions and people should inform themselves with the truth.
Deputy Chief Justice Raymond Zondo ruled that the right to privacy should not be limited to the home or private dwelling and should be extended to any private space.
For the cultivation of cannabis, he says the exact same rules should apply.More news: Canadian pot users could get flagged at U.S. border
A South African marijuana strain called Durban Poison has been rated among the "20 greatest marijuana strains of all times", by the United States cannabis publication High Times.
It will, however, remain illegal to use cannabis in public, and to sell and supply it.
In political terms, the landmark ruling emphasises the primacy of South Africa's constitution, which brushed aside the united opposition of numerous government ministries at a time when the authority and credibility of many of this young democracy's other institutions have been eroded by corruption and poor governance.
Zondo said the Constitutional Court would give parliament 24 months to correct the constitutional defects in the Drugs Act and the Medicines Act.
But what exactly does private use entail? The ruling means it will not be a criminal offence for South Africans adults to use dagga in private or to grow the plant at home for private use. "It's important for Parliament to make its position known as soon as possible", Meshoe said.
