Long ago when I was a child, I payed a visit to my grandmother (Father's side) and the place smelt absolutely foul and the wallpaper was tinted a disgusting brownish-yellow.
I tried smoking one of the cigarettes out of curiosity to see why people did it, and it was quite unpleasant. The place was littered with little plates overflowing with cigarettes.
That's the first and last time I visited my father's mother, who was also a binge drinker (Bonus information). It was very sad.
There's nothing wrong with being curious, but afterwards it is wise to learn from your experiences. Here is a website that goes into greater detail on the effects of smoking on the body:
