As I understand it, actual smoke is not used in theatrics. The fog you see is a heated up combination of water, glycol-based or/or glycerin-based fluids that are relatively non-toxic. You will also see use of dry ice and LN2 for some ground applications.
Actual smoke has a host of health related problems, so I would not expect to see them use it in any fashion.
