A college student has been put behind bars for supplying the £20 deadly drug that killed her friend.
Tragic Robert Chisholm, 38, died at his home on February 5 from a lethal combination of alcohol and morphine, or heroin.
His friend Sarah Thompson, who obtained the deadly dose of heroin from her dealer on his behalf, has now been jailed for a year.
Newcastle Crown Court heard the 27-year-old had supplied Mr Chisholm with the drug in the past and he went unconscious as a result.
Despite this, Thompson agreed via a text message exchange that she would supply him heroin on the day of his untimely death.
Prosecutor Neil Pallister told the court Mr Chisholm had joked "I will die lass" during the text conversation about how much he wanted.
The court heard when Thompson turned up at his house at South Durham Court in Sunderland with a £20 bag, she "showed him" how to find a vein so he could inject himself.
She then went to his bathroom to inject her share of the deal into her groin and found him passed out on the sofa when she came back.
The court heard she immediately alerted the emergency services but Mr Chisholm could not be saved.
Mr Pallister said: "Death was attributable to a combination of morphine and alcohol."
Thompson, of Chestnut Crescent, Sunderland, admitted supplying heroin and producing a small amount of cannabis found at her home.
Mr Recorder Ben Nolan QC said heroin causes "death and extreme misery".
The judge told her: "You are an intelligent young woman with a number of qualifications and the capacity to think clearly and intelligently.
"The effect of his ingestion of heroin was calamitous, he immediately collapsed and died.
"The post mortem report indicates the level of morphine injected into his blood was within potentially lethal range. His death occurred immediately after the heroin was administered.
"You are not, of course, charged with unlawfully causing his death and that must be recognised immediately.
"His death, immediately after taking the heroin which you supplied him, is an obvious and gross aggravating factor in relation to this offence.
"Particularly so because in interview you described a previous occasion when you supplied him with heroin and where he immediately overdosed and became unconscious.
"Having witnessed that, you continued to supply him with heroin and on this occasion there were the awful, tragic consequences which I have already referred."
The judge said the offence was "so grave" that an immediate jail term could not be avoided.
Vic Laffey, defending, told the court: "She is devastated at this man's death."
Mr Laffey said Thompson is now drug free and at college where she has obtained qualifications and made efforts to turn her life around completely.
Mr Laffey said Thompson made no attempt to deny her involvement in what happened and sought help as soon as she saw that Mr Chisholm was in trouble.
