Inauguration smoke of some sort

[ragrsrocalot]

I know Stevie is quoted as saying when it was confirmed that the Mac would be playing at Clinton's inauguration she said to " pack up the tranquilizers ", so we know we was tranqed out, but i noticed in this clip, Stevie exhaling smoke of some sort. Wonder if it was ciggies or weed? Stevie is sitting in the chair getting her hair done as Christine McVie looks on.
