I am older than you, @Hernamewaslola22 - I was born in the 60s - and my parents smoked all the way through my childhood, and my mum was still a heavy smoker right up until her death in 2022 (dad gave up when I was in my late teens).
Even when the news stories about the risks of cigarette smoke came out, mum didn't stop, and didn't stop smoking around dsis and me. She smoked in the car, and on long journeys this made me car sick and gave me a headache - but when I told her this, and asked her to stop, she refused.
I remember her coming to visit me, when I was a student nurse living in the Nurses' Home, and she lit up in my room, without even asking if I minded. By then, I'd been living in a pretty smoke free environment for a couple of years, and the way the smell stayed in the room afterwards horrified me - I hated it.
I can't help wondering how much damage was done to our lungs during childhood - they smoked around us while we were babies.
Even in her last years, whenever we visited her, she would smoke continuously around us - it didn't affect me much, because we live in Scotland, and she had moved to be near my sister (her favourite), more than 400 miles away from us. Dsis visited her a couple of times a week, and had to endure that smoky atmosphere every time - the woman is a cast iron saint!
