Medford, Ore.-- Smoking an E-cigarette is what Tylor Arnold calls the safe alternative to tobacco.
"There's no arsenic, there's no cyanide, there's no tar, there's no smell," said Arnold.
Arnold also sells them about 200 hundred a month at Vapor Legends in Phoenix.
It's becoming a lucrative business, they range from $20.00 to $200.00 a pop.
"It's amazing it gets away from cigarettes, cigarettes and the what 2,500 carcinogens involved with it."
But not always amazing just Wednesday Medford Fire and Rescue said a woman had a close call when her E-cigarette overheated.
Medford Fire Marshal, Greg Kleinberg said, "She discovered a pillow was smoldering and she looked and the E-cigarette the battery fell and shot up to the ceiling level."
Kleinberg said it's second time an E-cigarette started a fire in just months.
Employees at Vapor Legends said the key to safety is keeping an eye on the charger.
"When it over charges it'll heat up inside of a metal case or it will discharge inside of a metal case. When a battery sweats it can get up to 4,000 degrees almost instantly," said Arnold.
An instantaneous moment that's led several states to ban E-cigs all together.
