Nicotine pouches (also known as Zyns) are small, white bags that contain chemicals, flavourings and synthetic nicotine - the same addictive drug found in vapes and cigarettes. When placed between the lip and gum, nicotine pouches deliver a hit of nicotine into the body. Nicotine pouches can be marketed as 'tobacco-free', but you shouldn't be fooled into thinking that means they are safe.
