The mindset Singaporeans have nowadays is : Coz i dont like it,
the government should ban it. Gay parties, casinos, blogging etc.
are all really matters that have been blown out of proportion not
by the government, but by self-rightous people seeking to impse
their worldview on everyone else.
I say, learn to live with the smoke, avoid it as you have always
done, and encourage people to quit smoking. The government hasn't
put a foot wrong yet, and excise taxes have been very useful in
deterring new smokers.
