FABULOUS!
I use it, but nowadays only as a breath freshener.
My dear wife appears to burn 2 packs a day.
Well then perhaps it’s a regional thing, as I witness very few folks in these parts chewing gum…
There is certainly at least one bastard chewing gum in London - I didn’t see the freshly-chewed (and spat out) piece my seat on the Central Line and now my strides are in the freezer…
I’m posting from the same state you are… then again, I don’t know anyone besides my wife who chews gum.
Hell, I’ve seen priests chewing gum during Mass. (Usually when I went up for Communion, then you could see them subtly chewing).
I don’t know too many adults who chew bubble gum, though.
(When I was a kid, I liked getting Bubble Tape and putting the entire container in my mouth at once. Ugh, I can’t imagine trying that now.)
I can’t possibly be the only one who remembers Big League Chew - “Tasty Wads Of Shredded Bubblegum” (yes, the ads actually used the phrase “Tasty Wads”).
When I was a kid I used to mow through that stuff, a huge mouthful of that artifically grape-flavored stuff that had a strangely chemical aftertaste, like alcohol or acetone.
Made your whole head pucker. Mmm. I assume it went the way of bubblegum cigarettes since it was basically encouraging kids to pretend they were chewin’ tabaccy just like their favorite MLB players.
When I was about eleven I was chewing some ridiculous amount of Big League Chew in class. Like, half the size of my head, or something. The teacher called me up to the front of the class and actually took it out of my mouth with his bare fingers – then he took it around and showed it to everyone in the class. “Look at this! Look at the size of this!” From his tone, it was clear that he intended to expose me to the scorn and derision of my peers.
He failed to take into account the fact that they were all eleven-year-olds, too. 
Nope, it’s still around - in fact, my daughter was chewing some just a couple of months ago.
Not so much lately, but my habit used to be to pop in a piece of gum after every meal, and chew it until the next. Except, of course, while I was sleeping.
