with cigarette in hand vs with a cigarette in hand

[anhnha]

Sitting in his large chair with cigarette in hand, he looks rather drawn and quite uncomfortable.
Can I use "a cigarette" instead of "cigarette" in the sentence above?
Could you tell me what is the reason for using "cigarette" not "a cigarette" in the sentence above?

You can use either.

It's a matter of style, not grammar.

I prefer it like that.
