A woman was caught trying to smuggle drugs and a mobile phone into Norwich prison.
Kiya Brownfield, 27, admitted bringing cocaine, heroin and cannabis into Norwich prison on May 29 this year.
Brownfield, of Ashwell Road, Bury St Edmunds, also admitted bringing in a mobile phone on the same date.
Jailing her for six months at Norwich Crown Court Judge Stephen Holt told her the most serious aspect was bringing in a mobile phone.
He said that smuggled mobile phones caused huge disruption to prison life and said: "It is a very serious problem A deterrent sentence has to be passed."
However he accepted Brownfield had been put under pressure to bring in the items.
Ian James, for Brownfield, said her use of drugs got her in contact with bad influences who had then "commandeered" her to take in the drugs and phone.
