Being a Ninja is key...
Not that I would ever vape in or around any government building or vehicle. <wink> That Memo really upset me, but it stipulates a "tobacco product", and my SD mkII doesn't contain a lick of tobacco. FDA, USAF, who ever wants to call it a tobacco product is down right wrong IMHO. When I got chewed out and handed the memo, I was asked if I had any questions, and simply put "No Sir" Because that memo says it's a tobacco product that looks like an analog. And my vape looks nothing like an analog. Since folks dip in the building, how on the face of this earth can some one with a clear mind chew out someone for vaping. It doesn't stink nearly as bad as dip, and doesn't leave nasty water bottle filled with spit all over the place.
I'll never ever yell at any of my Airman for it, but the official answer is "no".
