Unless you live in a "no smoking" building, there is nothing you can do. I know the smell is disgusting and I would hate it too.
But she pays her rent and she has every right to smoke on her balcony. I like the suggesting to put a fan pointed out your window. It might help.
Also if you can afford it, ask the management if you can put in a window air conditioner. That way you don't need to open your window.
