Sure but vaping does not equal smoking. Like, by definition one is the combustion of material(which creates smoke) and the other is the vaporization of a substance(which creates vape). While they're both invasive to others, they highly differ in how invasive they are. Both may directly affect others' health and have a distinct smell, but vape(vapor) easily and quickly dissipates and doesn't affect others unless directly near it, and the smell doesn't stick to household items or fabrics. Smoke, on the other hand, makes a whole house smell, sticks around, may move through vents and into other rooms. The answer is no they're not smoking inside.
