Around 50,000 doses of illegal drugs were found along with £8,500 in cash when the Medicines and Healthcare Products Regulatory Agency and police offices raided properties in Knowbury and Cleobury Mortimer, in the south of the county.
A 31-year-old man has been arrested on suspicion of involvement in the sale of unauthorized drugs, possession of controlled drugs with intent to supply and money laundering.
A spokesman for the MHRA said those supplying illegal drugs were exploiting innocent and vulnerable people to make money and had no regard for the health and welfare of the public.
“Buying from unreliable suppliers greatly increases your risk of getting an inferior product and could harm your health,” they said.
“If prescription drugs are offered without a prescription it is not legal and the drugs supplied may not be licensed drugs in the UK meaning there is no guarantee that they meet quality and safety standards. Taking medicine that is falsified or unlicensed puts you at risk of serious harm. Put your health first and buy safely.
“If you think you have had an adverse drug reaction, are concerned about its safety or effectiveness, or think it is a questionable product, please report it to our yellow card system .”
“Self-diagnosis and self-medication can be very dangerous. If you have any concerns about your health, see your GP, get a correct diagnosis and if medication is prescribed, buy it from a legitimate source.
“Unlicensed medicines have not been approved for use by the MHRA, so we have not considered their safety and efficacy, or the quality of their manufacture. There are risks involved in taking any substance that has not been approved, including the potential to cause serious side effects.”
