Tricia smokes a colored (if I remember correctly) cigarette in only one scene and Patricia smokes in several scenes.
"Tricia also attempts to 'gross people out' by making herself look pregnant, then pulls out a can of snuff, and puts a dip in her mouth"
"Actually, it's Patricia who smokes blue colored cigarettes, in the role of a kooky art student. Tricia smokes medium-sized cigars in one or two scenes, with at least one good exhale. She is also seen holding a cigarette."
