Will the ban on importing e-cigarettes be overturned?

Prime Minister Scott Morrison is open to reversing a ban on importing e-cigarettes containing vaporiser nicotine.

Dozens of coalition government backbenchers have penned an open letter condemning the tough restrictions.

Mr Morrison said he would let the Minister for Health Greg Hunt deal with the blowback, but was keeping an open mind.

"I'm sure he'll be addressing that issue further with colleagues and take into account the various feedback that's coming back," Mr Morrison told 2GB radio on Friday.
