"[Poirier] is shown smoking extremely briefly ... Although super-brief, you do see a nice snap inhale that looks IRL. Unfortunately, the director cut before the exhale. :("
"[Eastwood] has a smoking scene where she's sharing a cigarette with Kim Poirier in the mall gallery. However, it's hard to tell if it's a joint or a regular cigarette. One drag, but no exhales [due to] too many cutaways to other characters."
