In Delaware a legal way has been found around the smoking ban and several bar owners have beaten being cited for violations of it.
The statute specifically states TOBACCO........nothing else (remember cannabis is in a different statute, and so I'm not talking about that). Several enterprising bar owners have stopped selling tobacco products in their bars, thus denying the state of those revenues, and now only carry legal products that do not contain any tobacco.
The nannyists haven't figured out yet how to get around a little quirk in the Delaware Constitution regarding the "title" of sections of State Code, and so thus haven't figured out how to prohibt the smoking of non-tobacco products.
What products that can be smoked other than pot are you talking about?
