Here is a list of definitions of various terms related to tobacco and other common addictions as to what do they actually mean. This will help to understand the nuances between the various terminologies. You are welcome to add to this list.
· Smoke is produced as a result of combustion (temperature > 800o C). When combustion occurs, new chemicals are formed via the process of oxidation. Hence, smoke contains several new chemicals different from those initially burned. Smoke can be produced by burning coal, wood, cigarettes, bidis, etc.
· Smoking is a practice in which a substance is burned and the resulting smoke breathed is absorbed into the bloodstream. The most common form of smoking is cigarette smoking or recreational drug use.
· Second hand smoke: Smoke that fills restaurants, offices or other enclosed spaces when people burn tobacco products such as cigarettes, bidis and water-pipes.
· Third hand smoke: It is not exactly smoke, but the “invisible” chemical residual of tobacco smoke contamination that sticks to clothing, wall, furniture, carpet, cushions, hair, skin and other materials in the environment after the cigarette has been extinguished.
· Vaping: Act of inhaling and exhaling a vapor or an aerosol. E-cigarettes do not produce tobacco smoke, but an aerosol, which is commonly termed as “vapor”.
· Vapor: When a substance becomes gaseous, at a temperature that is lower than its point of combustion (180-250oC), it is considered as vapor. Unlike smoke, the chemicals in vapor are the same as those found in the vaporized substance.
· Aerosol: Suspension of tiny particles of liquid, solid or both within a gas.
· Electronic nicotine delivery systems (ENDS) and Electronic Non-Nicotine Delivery Systems (ENNDS): Products that heat a solution to create an aerosol which frequently contains flavourants, usually dissolved into Propylene Glycol or/and Glycerin; the aerosol is inhaled by the user. Most common example are e-Cigarettes that that do not burn or use tobacco leaves but instead vaporise a solution the user then inhales. All ENDS (but not ENNDS) contain nicotine.
· Heated tobacco products: Also known as “Heat-not-Burn” products, they produce aerosols containing nicotine and other chemicals, upon heating of the tobacco, or activation of a device containing the tobacco, which are inhaled by users, through the mouth.
