Roll-your-own refers to a cigarette made from loose tobacco and rolling papers. Roll-your-own products are sold as a pouch of tobacco for rolling hand-rolled cigarettes, sometimes with the rolling papers provided in the pouch. Loose filters can also be bought and added to the rolled cigarettes. Hand-rolled cigarettes also give smokers the ability to roll cigarettes of any size they choose. Like all tobacco products, use can cause various diseases. Roll-your-own cigarettes are also preferred by some smokers because they are cheaper than machine-made cigarettes.
