Don`t shoot me down in flames here for saying this, BUT whether you are vaping or smoking, everyone has the right not to be infused by any type of smokey cloud / vapour / cig smoke / weed, or whatever. This is the reason the ban was probably brought in.
Now, i wouldnt be so meek if they called for a vaping ban outright, but to do so indoors, i guess it is only fair to look at it from the other side of the fence too. Just my opinion ofcourse.
HOWEVER i agree, the government should get their dirty mitts off the vaping industry and the decision should have been left to the owners of these businesses / establishments.
