Multiple corroborated reports indicate Chinese authorities moved to reclassify a commonly misused cough suppressant as a psychotropic substance and then introduced further tighter prescription and dispensing controls after young people shifted to alternative substances.

Media accounts and official statements cited in the corroborated material say authorities adopted additional restrictions in April of a recent year following earlier controls, and that Chinese officials launched campaigns and stepped up enforcement and regulatory measures in 2025–2026 aimed at reducing youth misuse of prescription drugs. The reported regulatory steps include tighter requirements for online pharmacies and prescriptions, such as real‑name verification and stricter prescription review procedures.

The corroborated reporting describes online chatrooms and social media as channels where teenagers share tips, recommended drugs and methods to obtain substances, which sources present as facilitating the behaviour documented in qualitative reporting.

International monitoring bodies and global reports are cited in the corroborated material as identifying non‑medical use of prescription drugs and regulatory challenges — including online sales — as concerns that call for improved controls, surveillance and cross‑sector cooperation. Academic literature and health surveillance studies cited in the corroborated context (including a 2015 multilevel analysis and other outpatient studies) indicate non‑medical use of prescription drugs among Chinese adolescents has been documented in prior years.
