Four of the drug dealers – James Stubbings, Deborah Northwood, Gordon Smith and Andrew Morgan – were all said to have each benefited by £250,000 from the conspiracy.
In addition Kenneth Preston's benefit was calculated at £100,000, David Maloney's was valued at £48,000 and Ross Myatt at £50,000.
The figures were revealed during a series of Proceeds of Crime hearings at Birmingham Crown Court when applications for confiscation orders were made against the defendants following extensive financial enquiries by the West Mercia police economic crime unit.
Judge Michael Chambers QC imposed orders on all seven defendants to hand over monies – totalling around £105,000 – from their estimated available assets.
The realisable assets of 31-year-old Stubbings were said to be just £3,000 and including hidden assets.
Stubbings has until February next year to pay up or face a further two months in prison.
