There are many smoke-free alternatives, for example, e-cigarettes and heated tobacco products and snus.
E-cigarettes heat liquids (that usually contain nicotine) instead of tobacco to create a vapor that is inhaled.
Heated tobacco devices heat tobacco to a temperature well below its burning point, releasing a nicotine vapor (and tobacco-like flavors) that is inhaled.
Snus is a smokeless tobacco product made from ground-up tobacco usually enclosed in a small pouch. It is placed between the gum and the lip.
