The most recent numbers from the Centers for Disease Control show 1.78 million middle and high school students tried e-cigarettes in 2012.
The battery powered devices are largely unregulated and a growing concern for the medical community and school districts.
The Cumberland County School District is in the process of adding e-cigarettes to their tobacco policy.
Administrators have recently drafted the changes and will have the first reading at Thursday's school board meeting.
Cumberland County High School said e-cigarettes have been a growing problem for them this year.
The device heats up a liquid to give off vapor instead of smoke. Some have nicotine, others don't, but its difficult for administrators to tell the difference.
"We get phone calls saying we saw this student—on the bus or in the hallway—smoking and when we go to the student and see what they have it turns out to be an e-cigarette," said Principal Jon Hall.
Hall said they have been disciplining students caught with e-cigs the same way you would tobacco but right now there is no written policy to back him up. He and Director of Schools Donald Andrews hope the school board's approval will change that.
"I can understand that parents and students if you don't have certain things in writing people say you're changing the rules as you go you can become inconsistent," said Andrews.
"We felt it was best just to say it's not going to be a part of our school system."
In Tennessee, it is illegal for anyone under 18 to buy e-cigarettes, but they are not regulated on a federal level or online.
The FDA is expected to make announce regulations as early as this month.
The restrictions are expected to mirror those of regular cigarettes.
