Regulations and the ever increasing price of cigarettes are making the taking up of smoking too expensive for teenagers nowadays. Never mind the price of e-cigs. They just cannot afford them.
So I think our generation is the last to smoke or even vape. People won't start vaping if they have never smoked.
Just a thought. I sell cigarettes from my shop and just checked my cigarette purchases per week 2 and 3 years ago.
Purchases was R3600 to R4000 pw. Now it is +- R1200 pw.
