US and Canada have seen great decreases after big anti smoking campaigns in the 90s and laws in the 2000s. Apparently European countries have not. But I have no idea about Australia and New Zealand.
I thought this was an easy question to answer, but I realised that I don't really notice people smoking unless it's somewhere they aren't meant to (illegal to smoke in indoor public spaces including near eating areas or on public transport, and in a car if a kid is also in the car). But people smoked around me for most of my early childhood so it's just something that I've internally normalised and don't notice
The statistics bureau publishes stats every year or two on smoking and according to 2022s:
58.3% of adults have never smoked (including vapes and e-cigs)
10.6% of adults are daily smokers (half of what it was 20 years ago)
14.4% of adults vaped or used an e-cig
People in rurual/outer regional areas are almost twice as likely to smoke
People in areas of "most disadvantage" (ABS talk for poor places) are almost 4x as likely to smoke than those in areas of "least disadvantage" (ABS talk for rich places)
And apparently among daily smokers, the average amount per day is 11.8 cigs
The price of a packet of cigarettes isn't going to be the difference between them surviving and thriving, so they opt for the small amount of short term enjoyment.
I can dig it, I was that poor once. It's like I could go all week without any enjoyment whatsoever, and maybe in a few months I'll have enough to do something boring but sensible that might slightly improve my long term prospects.... Or I could blow the last few bucks in my bank account on a pack of ciggies and have some guilty pleasures immediately.
My brother quit smoking when he changed his job to one with scheduled breaks.
The money he saved allowed him to upgrade from a fourth-hand shitbox to a second-hand luxury 4WD.
A lot of people who smoke at a high-demand workplace as an excuse to have a break. My advice is to have a small water bottle or drinking glass and take a break to refill it.
I suppose - 10.6% of ~20 millionish is still a lot, but compared to how high it used to be, it has gone down a lot. In the 80s over 40% of adult men were smokers
