On a 4-1 vote, the Roswell City Council has given final approval to a measure outlawing the use of e-cigarettes and vapor pens in city parks.

The vote came amid uncertainty over the health risks of such devices, with a number of safety studies in progress. The Centers for Disease control says their use has skyrocketed among middle and high-school students, and worries the devices are a gateway to nicotine addiction, while supporters say the hand-held nicotine delivery systems have helped thousands of smokers to quit.

The council gave the plan first-round approval in August.

The council also considered a number of roadway matters, including authorizing city officials to sign a contract with Blount Construction to add the 2016 street resurfacing/sealing program for $1,8750,000.

It also approved a resolution instituting a pause in street light installation on Roswell roads.
