Soweto hosts first ever cannabis festival
I think there may be some confusion here. Soweto, a township in Johannesburg, South Africa, has not hosted a cannabis festival. While cannabis is legal for medical and recreational use in some countries, it is still illegal in South Africa, and there have been no reports of a cannabis festival being held in Soweto or anywhere else in the country.
However, there have been efforts to legalize cannabis in South Africa, and some organizations have been advocating for its legalization for medicinal and recreational use. In 2018, the South African government announced plans to legalize cannabis for medical use, and a bill was introduced to parliament to regulate the cultivation, possession, and use of cannabis for medical purposes.
It's possible that you may be thinking of a different event or location. If you could provide more information or clarify what you're referring to, I'd be happy to try and help you further.
