In September, Katherine was guest on "The Late Show with David Letterman" where she chatted about her battle to quit smoking. She revealed that she had switched to using an electronic SmokeStik® and credited the device with helping her stop using conventional cigarettes.

When manufacturer SmokeStik® discovered she was a fan, they created a special model called The PitBull and will donate a percentage of the proceeds from the sale of the device to benefit the Jason Heigl Foundation's Compassion Revolution program.

The electronic device simulates the smoking experience, without the tobacco, tar and many of the chemicals that are found in a traditional cigarette. It does not have carbon monoxide, tar, or any other known cancer-causing chemicals and is free of ashes and stubs as it has no open flame. The user is essentially "smoking" a mist or vapor. This vapor is created as liquid glycerine, propylene glycol, nicotine (if chosen by the user) and food grade flavorings are vaporized by a tiny component called the atomizer.
