Smoking's not allowed on Washington's Metro system. But what about e-smoking?
The week before last, I was riding on the Orange Line when I saw a woman holding what I thought was a high-end felt-tip marker. It had a round barrel that tapered to a narrower point. Then she stuck the narrow end in her mouth, sucked, and blew out a white cloud.
It didn't smell like cigarette smoke, at least from where I was sitting. It seemed like more of a vapor. And, indeed, that's what it was.
