It seems smokers are a dying breed, with little fuss kicked up over the smoking ban in Brisbane's Queen Street Mall which began today.

Small groups of smokers huddled at each entrance to the mall, while a few continued to puff away in the mall oblivious to the change but most of them were not bothered by the new law.

Tina Small, 22, works in the mall and said she understood the ban.

"Honestly, smokers know how bad it smells and these days I actually get a bit self conscious smoking in the mall," she said.
