@Willitneverend indeed, intrusive does not begin to cover it. There's a puritanical streak a mile wide in that society.
The cigarettes thing is a particlar farce. Everyone is still smoking, they are now paying over the odds, inhaling fuck knows what into their lungs and the government are getting no tax revenue from it. And they are hardly in a position to lose tax revenue at this point.
Their alcohol ban (fortunately they did now lift that) also included wine export abroad. Again more tax revenue gone, one of their major industries terribly damaged and tens of thousands of jobs lost.
I do get that SA has a huge problem with alcohol-based violence and it's attendent stresses on the healthcare system so I can see what the initial thinking behind a ban was but it's all been so badly thought through. Not to mention that there have now been a good couple of dozen deaths from bad homebrew.
And then there's the issue of the number of people murdered by the police for their own protection
