Public ‘at Risk’ from Illegal Weight Loss Drugs as Black Market Expands Rapidly
UK regulators have issued a stark warning that the public is "at risk" due to a rapidly growing black market for weight-loss drugs and illegally traded medicines. The Medicines and Healthcare products Regulatory Agency (MHRA) has highlighted the severe dangers posed by this illicit trade, which is now generating profit margins comparable to those of cocaine and heroin.
Massive Seizures and Genuine but Unsafe Products
In 2025, the MHRA seized almost 20 million doses of illegally traded medicines, with an estimated value of nearly £45 million. This included 81,000 doses of GLP-1 drugs over the last three years. Andy Morling of the MHRA revealed that 99 per cent of the seized GLP-1 drugs are genuine but unsafely produced, raising significant health concerns.
Morling emphasised that these seizures represent only about 10 per cent of the overall problem, indicating a much larger underground market. The black market's scale and profitability are alarming, with criminals exploiting high demand for weight-loss treatments.
Dangerous Sales Channels and Fatal Risks
Criminals are increasingly selling unlabelled weight-loss drugs through social media platforms and unlicensed beauticians. Some operations involve manufacturing fake products, including insulin-filled pens that authorities warn "could have killed people." This unregulated environment has led to tragic consequences.
The death of Karen McGonigal, allegedly after receiving an illegal semaglutide injection from a beautician, underscores the fatal risks associated with these illicit drugs. The public often struggles to differentiate between legitimate healthcare providers and illegal sellers, exacerbating the danger.
Regulatory Challenges and Public Awareness
Regulators face significant challenges in combating this "wild west" of weight-loss drugs. Morling stated, "We can’t arrest our way out of this," highlighting the need for broader strategies beyond enforcement. The MHRA is urging increased public awareness and vigilance to protect consumers from these hazardous products.
As the black market continues to thrive, authorities are calling for stricter monitoring of online sales and better education on the risks of unregulated weight-loss treatments. The situation remains critical, with ongoing efforts to curb the illegal trade and prevent further harm to public health.
