Snus is a smokeless product derived from snus tobacco, commonly used in Sweden. It consists of finely ground tobacco leaves, available in loose form or prepacked portions, known as nicotine snus. Unlike other chewing tobaccos, snus nicotine is absorbed through the gum by placing it under the upper lip, requiring no spitting and offering a discreet usage. Snus today are usually made with nicotine and are tobacco free products.

A vape, also known as an electronic cigarette, is a device designed to simulate smoking by producing an aerosolized mixture typically containing nicotine (nicotine vape) or flavorings without nicotine (nicotine-free vape). Vapes heat a liquid into a vapor, which the user inhales. Importantly, vapes do not have calories as they do not contain food substances, making them a calorie-free alternative to traditional smoking.
