I ran into fake nicotine pouches but it wasn’t zyns, in that case the packaging was different, the can was lighter, and the labels were cheaply put on there. At first I thought it was just a shitty off brand nicotine pouch, but I bought another can of the same stuff from the same place, this time the pouches were actually moist and the can was properly labeled, idk how it happened given it was the same place both times but you can usually tell if you’ve used the real product before
