The researchers identified the most popular episodic programmes through an online survey of 750 youth and young adults between the ages of 15 and 24 and found Netflix to be the most commonly-watched streaming service.
Researchers viewed more than 400 episodes and 350 hours of programming to document tobacco depictions from the shows' 2015-2016 and 2016-2017 seasons. Each image of a cigarette pack or individual product was counted as a separate incident — even if multiple packs or products were shown in the same scene.
Netflix hits Orange is the New Black and House of Cards both registered a high number of tobacco depictions, but researchers found Stranger Things to be the worst offender, with 100 per cent of the episodes they coded including tobacco.
A Netflix spokesperson told EW the company recognised that "smoking is harmful and when portrayed positively on screen can adversely influence young people".
"Going forward, all new projects that we commission with ratings of TV-14 or below for series or PG-13 or below for films, will be smoking and e-cigarette free — except for reasons of historical or factual accuracy. For new projects with higher ratings, there'll be no smoking or e-cigarettes unless it's essential to the creative vision of the artist or because it's character-defining (historically or culturally important). In addition, starting later this year, smoking information will be included as part of our ratings on the Netflix service so our members can make informed choices about what they watch."
