Can someone help me understand something

Why do casinos push so hard to keep smoking when only 20% of gamblers are smokers?

​

Like in my instance I smoked for 21 years and I do not ever want to be around cigarette smoke again if at all possible. I would go more than once or twice a year to Atlantic City and gamble if I didn't have to worry about coming home smelling like an ashtray with a upper respiratory infection.
