My father smoked a lot growing up but we never went without.
Granted we didn't have a lot of spare money as I came from a very large family but we were always well dressed, clean, fed and loved. My mum worked part time and dad worked all hours.
We never went aboard as the costs would have crippled anyone back in the 70s and 80s due to how big my family were but we spent our summer hols camping, sometimes for weeks on end (dad would leave to go to work on Sunday afternoon and come back late Friday night) and Christmas and birthdays our present piles would be sky high!
The house was filled with books and toys to keep us entertained. We always had new school uniform and back then you had to go to specialised uniform shops and wear blazers.
We went on weekend day trips with my older siblings if mum and dad were at work and go fishing with my dad at weekends (so mum could have the house to herself for a day!) we had a weekly pocket money and mum would always buy us a comic/ magazine on a Friday.
As I grew up and they had more cash it would be trips to Miss Selfridge for the coolest clothes and make up for me and game shops for my brother. I was so hip it hurt! 
We grew our on veg at an allotment and all chipped in.
The house was busy but always clean and decorated and any painting jobs needed was due to wear and tear from many people rather than the dreaded yellow stained tobacco walls.
It never occured to me growing up that my dad was "burning our money". He didn't drink or go to the pub or working mans club. He would be at home with all his family.
He worked his arse off all his life. Why would I ever begrudge him his "ciggie money". He even managed to quit overnight when he was older for his health.
As a grown up I realise how MUCH my mum and dad sacrificed so we never went without.
My memories are filled with happy thoughts and not that dad had spent money on himself instead of buying me the latest fad thing.
I know people who can afford to spend £10 a day on coffee and lunch without blinking an eye. I have friends who have a 12 crate of booze delivered each week and ones that go on holiday twice a year..
People budget for things, as do smokers. It's what adults have to do.
A packet of tobacco, filters and papers can set you back around £12 and unless you smoke like a chimney, can last a week.
There are liable to be more poor parents who go without eating so their children can eat than poor parents who spent their money on cigarettes than food for their children.
TV programmes about the poor can be very biased as you only get to see that one person who is being filmed and so you imagine all poor smokers to act like that.
You can be rolling in cash and be a non smoker but still be a rubbish parent.
I have no idea how my parents managed but they did and all with my dad smoking. 😱
I may have not had a foreign holiday until I was 14 but by god was I loved.
