"Dhavernas smokes numerous times, with well-lit exhales and up-close inhales. It's unclear whether she's IRL (she may not be) but she does a good job in this movie. Lewis steals a cigarette from Dhavernas in one scene and has a couple of drags, but she's not IRL. Walsh has one hit on a joint"
"Caroline smokes in 6 scenes: the film begin whith her exhale, several drags and exales. Holly, a non-smoker, smokes one time. Amanda smokes a joint"
