Marcus conducted an experiment to investigate public perceptions about whether a teenager who vapes is more likely to engage in underage drinking than a teenager who does not vape. He gave participants from a local community centre two different scenarios about a teenager's weekend activities.
In the first scenario, the participants had to rate how likely it was that the teenager, who does not vape, would engage in underage drinking (Condition A). In the second scenario, the same participants rated the likelihood for the teenager, who does vape (Condition B).
The participants were asked to provide a rating score from 1 to 10, where 1 was 'not at all likely' and 10 was 'extremely likely'.
