Smoke emit slowly

How do you get a smoke exhale sim to begin as a wisp and not a ball of smoke that fills and then emits. I am trying to make smoke that slowly comes from the mouth that starts after they take a hit.
Hope everyone can contribute ASAP.

Hi there, can you provide a reference video so that I can better understand the look you’re trying to get? I think I can help but I want to be sure what direction you’re trying to go in.
