Wet pouches deliver faster nicotine release, stronger burn, and intense flavour, but fade quicker. Dry pouches release nicotine slower, last longer, and are more travel-friendly. Wet pouches are common in Sweden/Europe (e.g., Swedish ZYN), while dry pouches dominate North America (e.g., U.S. ZYN). If you want a stronger hit, go wet; for longer-lasting, go dry.
