In 2016 researchers created a variety of "dissuasive cigarettes" to find out which kind was the biggest turn-off. "A 'minutes of life lost' stick was the most aversive of the stimuli tested," reported the researchers.
From Weird Universe (which has a photo of the cigarettes described below):
One of these cigarettes had a "smoking kills" warning printed directly on it. Two others were unpleasant colors: "slimy green" and "faecal yellow-brown." The fourth was printed with a graphic depicting "15 minutes of life lost."
