yes, I've seen this many times.. here in Qatar and in many middle eastern countries..I also so some woman smoking cigarettes in the U.S. She was next to me in one of my classes.. and then went out for a smoke.. she told me that she smoked a pack a day...and she could never quit!
sadly, law can never do anything about this.. law doesn't even prohibit pregnant ladies from drinking alcohol, let alone smoking! Even though I think that if those ladies can't take care of their babies while in their womb.. then they can't take care of the baby when he/she's out!! period..
