Usually people use herbal cigarettes,and the amount that they inhale depends on the actor, but they ARE smoking.
Keeping it in your mouth (cigar-style) instead of letting it go down into your lungs could be a strategy as well."
That would make a whole lot of sense. I do wonder, can smoking herbal cigarettes still damage the lungs or throat? I mean, in a show like Bonnie and Clyde where you have so many songs that require incredible endurance and a consistently high tessitura, how do they manage smoking?
