The jury's out on e-cigarettes, touted as a viable alternative to smoking regular cigarettes.
According to Dr. Archelle Georgiou, e-cigarettes simply haven't been around long enough to determine if they're safe or unsafe. Her verdict? Smoker, beware.
As for effectiveness, Dr. Georgiou cited a Boston University study that looked at about 200 people and about 60 percent said they cut back on regular cigarette use while a third stopped smoking completely.
Here's the bottom line: There aren't any long-term studies that can determine how safe and effective e-cigarettes truly are. More research and regulations are needed, so in the meantime, proceed with caution.
