Seattle Times: fact-check, anyone?

The Seattle Times joins the growing chorus in support of I-901. In the middle of an otherwise bland editorial, this bomb gets dropped:

In Helena, Mont., a study found that the number of people going to the emergency room for heart attacks dropped by almost half after smoking was eliminated for six months in bars, restaurants and other workplaces.

Wow. That study has been so thoroughly debunked that recycling it is a form of palpable idiocy.
