Australia had similar campaigns and decreases. We were the first to bring in plain packaging laws.
There are still people smoking but the price of a pack of cigarettes is astronomical($55-60) compared to 10 years ago and alot of smokers I know are moving to vaping.
The black-market for cigarettes is getting bigger too due to prices.
Couldn’t say, sorry mate. I’m pretty sure you need a doctor’s script for nicotine vapes these days(I think they have been classified as nicotine replacement therapy).
Most of my friends are buying liter bottles of concentrate off the net(not sure about legality of this) and filling their own carts. I don’t smoke or vape.
