The editorial take
The Benadryl challenge has circulated on TikTok since at least 2020, prompting multiple hospitalizations and at least one prior teen death. This case renews scrutiny of platform accountability for viral challenges targeting minors, particularly as the UK moves to ban social media for under-16s.
