I work on a manufacturing site and we have a strict no-smoking policy. We do provide a designated smoking area for smokers on site.

Recently there has been an increase in employees using e-cigarettes and this has become an issue for us as we do not want them to use them in the offices, factory, etc. As they are considered non-smokers and therefore are still entitled to a smoke free environment, we are unsure how to address this problem.

Is anyone willing to share their experience in dealing with vaping or share their policy with me?
Any help is much appreciated.
