I grew up in a relentlessly smoking household - my father worked for Players, as did his brother and many of their freinds. The house was always full of free ciggies, and lotsa smoke. I started when I was about 18, though I'd taken puffs before that. My sister never started as she had bad asthma growing up [no doubt the smoke was a partial cause]. I took loads of time off school with bronchial and sinus problems. But almost everyone smoked in the 50s and 60s. My freebies made me really popular when I first went to university...
I finally gave up aged c28, following years of chronic respiratory disease, and I still suffer from all sorts of respiratory / ENT problems. Ciggy smoke crucifies me - I'm ethically totally against banning things, but cigarette smoke totally disables people prone to sinus and lung disease, even if it doesn't kill us. My father died of lung cancer, as did several friends and two of my ex-lovers, both chain smokeers all their lives. It's not a death I'd wish on anyone. The one who lived longest also had emphesyma for many years - a really horrible disease which cause dhim to cough up vits of lung after any sort of excercise [!!]. My dad had artereosclerosis from his 50s as well, so couldn't walk far, which really upset him too.
The matter of stinking clothes and hair and the foul smell of cigarette smoke - esp stale smoke, nasty though that is, is a small matter beside the damage that tobacco smoke does. So yes, I'm really looking forward to the day...
Btw, studies show 'black tobacco' as found in eg Gitanes, or Russian or Spanish brands, is far less harmful than the cured Virginia most people smoke. It's the curing and the chemical additive which kill, not tobacco itself. So if you must smoke, change your brand to black tobacco or even roll-ups which don't have so many chemicals in them
