DULUTH, Minn. – Across the country, more localities are considering what restrictions should be placed on electronic cigarettes, and Duluth, Minnesota, is no exception. Recently, the City Council heard ordinances that would regulate the sale and use of the devices, the Duluth News Tribune reports.

None of the ordinances would outright ban e-cigarettes. Currently, more than 12 cities in Minnesota have approved regulations that place e-cigs on par with tobacco products for licensing and sales are concerned, as well as where e-cigarettes could be smoked.

The Duluth regulations would equate electronic cigarettes with cigarettes for use indoors and in particular outdoor venues, such as public parks. The devices would also be under current tobacco license restrictions. The council said it wanted to err on the side of health, even though the jury is out on what dangers, if any, e-cigs poise.

“We just don’t know yet,” said City Councilor Jennifer Julsrud. “If it’s determined it’s safe, we can change.” Three years ago, the U.S. Food and Drug Administration tried to make e-cig companies list the products as drug delivery devices, which would be under the regulations of the agency.

Electronic cigarettes have become increasingly popular lately, with record sales predicted in the coming years and retailers embracing the tobacco alternative. However, workplaces are beginning to regulate the use of electronic cigarettes as more people start to use the devices.
