Tobacco discrimination at work

The speculation and rumors have been circulating for months now, but still no release of the 'official' new policy. The latest twist going around today is that not only are they going to ban smoking on company property (including in your own personal vehicle), but that no legal tobacco products will be allowed on the premises! At first I thought my coworker was just kidding around, trying to get me riled up - but 'twas not the case. How the feck will they be able to enforce this - mandatory oral cavity inspections to make sure someone isn't chewing, car searches to look for butts in the ashtray?!?
Although I've tried to not let it (as nothing is 'official' yet), this has upset me to the point where I can't get my mind to stop reeling - and it's beginning to effect my health in ways that smoking cigarettes never has. Anxiety attacks, trouble sleeping, mad at the world... although I know it sounds crazy, this may very well be the straw that breaks this camel's back.
Before posting a pro anti-tobacco comment, think long and hard about why someone could and should be upset about a policy like this.
Stay tuned for updates...
