The pouches - flavored Blue Raspberry and Fruit Punch - weren't nicotine. The event is hosted by Wip, a start-up behind flavored "energy pouches." The products are part of a fast-growing category of caffeine pouches marketed as a trendier, cheaper and more discreet alternative to coffee, energy drinks and pre-workout powders. In recent months the pouches, which have circulated in social media mentions for some time, have been popping up more frequently in the wellness sphere and in social settings. Though many brands, including Wip, say these products are intended only for adults, experts who study adolescent behavior have noted that as more young adults talk about these pouches on and offline, they're entering the teenage lexicon as well.
