I can READILY understand gettin' rid of the Damn BUTTS...
Data's Calabash here...as a lifelong hater of anything to do with those "damn butts", if what New Zealand's military plans to do was STRICTLY limited to cigarette prohibition, I'd be 100% in favor of it.
The U.S. military, from the Revolution through the Civil War era, was more-or-less strictly clay churchwardens and stogies (pipes more-or-less constant through the whole period, with cigars coming in by 1861) and if it were to do the same, that would be a huge plus for the Department of Defense — and END one of the greatest causes (from cigarette self-pollution) of avoidable disease in military veterans, period.
Natural tobacco was the prevalent reality of smoking pleasure before 1865 (think about it, crude oil wasn't pumped out of the ground on a commercial basis ANYWHERE in the United States before 1859) before toxic petrochemicals arrived in "butt-stuffins" very shortly after the Civil War's conclusion...even today, for those of us who rightly choose natural-leaf-ONLY, hand-made cigars, and naturally-sourced, hand-blended pipe mixtures; simply avoiding consumption of any form of hard liquor "at-or-around" the time we're lighting up (as I don't touch that "hard-stuff" stuff in any way!) and staying away from those "damn butts" for my entire life as I've always done, can keep one from being harmed on the whole.
And I do remember speaking many years ago (1980s) having a very pleasant conversation in Braintree, MA with a USMC corporal from South Carolina who was enjoying his briar, and living south of Boston while he was serving at the now-closed Aouth Weymouth NAS, and had never touched those "damn butts" himself...I hope he's still with us (never caught his name, though)...I also hope he's been able to enjoy them ever since, and will still be able to enjoy his briars in the future, although he's most likely retired from the service by now.
If OUR servicepeople in uniform want to enjoy a pipeful or cigar in an appropriate situation and timeframe, they should CONTINUE to be able to enjoy them...if the Federal government simply wants them to be "damn BUTT-free" while still freely allowing them to enjoy a briar or stogie from time to time, though, that's just that much better.
