This TV commercial, from the National Cancer Institute of Thailand, aims to raise awareness of the realities of second-hand smoke. It is a simple demonstration that explains that when you smoke, so do others around you. It begins with a person taking a puff on a cigarette. The camera then tracks down the length of the cigarette to reveal a second filter on the other end with another person inhaling the smoke. A title appears that reads “YOU NEVER SMOKE ALONE.” This is followed by the logo from National Cancer Institute of Thailand.
