Based on survey responses from 1,002 participants, this study evaluated how social media users assess, interact and engage with information related to the illegal sales of prescription medicines. Findings suggest that individuals generally perceive online pharmacies and social media platforms to be safe and respondents are confident in their ability to acquire legitimate medicines. The authors note that this false confidence has the potential to lead to patient harm given the prevalence of counterfeit and substandard medication available on these platforms.
