A 35-year-old man who pleaded guilty to intimidation and drug offences was remanded in custody by Worcester Crown Court.
Darren Richards admitted making threats of violence towards a prosecution witness in a court case.
He also admitted two counts of being concerned in the supply of class A drugs.
Richards, of Much Birch, was one of a group of people buying drugs in bulk to share among them, said Michael Gray, defending.
Recorder Roger Evans was told that Richards is due to be sentenced with Susan Thomas, a co-defendant in the drugs case, when both of them can be brought to court together.
