A pharmacist in the UK has raised concerns regarding the use of medications like diazepam and alprazolam by 4.8 million individuals. Recent findings from Oxford Online Pharmacy reveal that one-fifth of adults have acquired prescription-only drugs unlawfully, with anti-anxiety medications being the most prevalent.
Based on the latest estimates, approximately 4.8 million adults in the UK could fall into this category. Additionally, 10% of respondents admitted to being offered illegal medication from unauthorized sources, such as online vendors, salons, corner shops, or acquaintances, but declined the offer.
A survey of a nationally representative sample of UK adults revealed that over a third of those who acknowledged obtaining medication from illicit sources did so for anti-anxiety drugs like SSRIs, SNRIs, and benzodiazepines such as Valium and Xanax.
The primary origin of illicit medications is online sellers, including unlicensed internet pharmacies. In a significant operation by INTERPOL known as Operation Pangea in June 2025, the MHRA confiscated nearly 8 million doses of illegal medicines.
Kiran Jones, a Clinical Pharmacist at Oxford Online Pharmacy, issues a critical alert to individuals contemplating or already using black market anti-anxiety drugs. Anxiety is a prevalent mental health condition globally, affecting an estimated 4% to 5% of the world’s population at any given time. The rise of a black market for anti-anxiety medications, in addition to legally prescribed ones, is a worrisome trend.
Illegally obtained benzodiazepines may resemble authentic medications but could be counterfeit pills containing hazardous levels of synthetic opioids like fentanyl. Dependency risks are also high with these substances, particularly with prolonged use leading to tolerance and potential addiction.
Jones emphasizes the dangers associated with acquiring prescription medications from unlicensed sources, highlighting the absence of regulation and oversight in the black market. Financial and personal safety hazards, including identity theft and involvement in criminal activities, are significant concerns for individuals engaging with illegal suppliers.
Only taking anti-anxiety medications under medical supervision with a valid prescription is advised due to safety reasons. Jones underscores specific indicators to watch for when considering medication from unverified sources, such as discrepancies in appearance, packaging integrity, and payment methods.
If there are doubts about the legitimacy of an online provider like a pharmacy, verifying registration with the General Pharmaceutical Council is recommended. The UK Government’s FakeMeds campaign provides valuable insights on identifying suspicious online sellers.
Individuals should exercise caution when offered medications through social media or unverified channels, as licensed medical professionals and regulated pharmacies are the sole authorized sources. Suspected counterfeit medicines should be reported to the MHRA via the Yellow Card scheme. In case of adverse effects, whether from legally or illegally obtained drugs, seeking medical assistance promptly is crucial. In emergencies, dial 999 for immediate help.
