[Michlib-l] E Cigarettes

I think this has been discussed on here before but I guess I didn't pay close enough attention to it.  What is your policy on the e cigarettes?  Do you allow them?  If not, on what basis?  I would like some samples of policies that include this.  Or maybe we don't need anything specific and just our "No smoking" policy is enough?  Thanks for any input. Lois Hartman Watervliet District Library
