Craig Shepherd, 26, and Maxine Turner, 41, both of School Knott Drive, pleaded guilty at Carlisle Crown Court to conspiring to supply both cocaine, a class A drug, and cannabis resin, which is class B.
Turner also admitted possessing cannabis resin with intent to supply it.
The court heard the pair – both long-term users – sold drugs as a way of raising the money they needed to fund their own habits.
Turner was jailed for four years.
Shepherd got three years.
