Biggest problem is that real Cotton Candy is made with 95-100% White Sugar.
Something we can't vape unfortunately, and the artificial sweeteners just don't cut it IMO.
Have you tried any TFA Circus Cotton Candy?
I've only used it a couple times awhile back, and I can't even remember what it tasted like, lol.
Brown Sugar, FA Meringue, FA Marshmallow, or other sweet flavors might help in small amounts like 0.5% each.
Probably still gonna need a bit of sweetener added.
Think I remember reading somewhere that some were just mixing like 10% Cotton Candy/EM.
Not positive on the amount tho, could have been even more, lol.
