If your state has passed a law banning indoor smoking, do NOT write or call some state official to find out if it is OK for you to use your e-cigarette indoors.
The chances are excellent that e-cigarettes are not included in the law as written. The only state that we know of that has a law on the books specifically including e-cigarettes in their smoking ban is New Jersey.
Someone asked the Virginia Department of Health if e-cigarettes were included in our recently passed law, and they decided to play semantic games and expand the scope of the law beyond what the legislature specified. We are still trying to get this misinterpretation of the law corrected.
