A drug addict who received the most complicated sentence a Yukon judge had ever prepared was found to be in breach of it last week.

Shannon Wentworth, who robbed a cab driver of $50 at knifepoint last September, was given a number of strict rules to live by, as part of a four-month conditional sentence, to help the 18-year-old overcome her drug addiction.

As part of the sentence she received on Jan. 5, Wentworth was to undergo regular drug testing.

Three weeks into her sentence, Wentworth was found with cocaine, morphine and sleeping pills in her system.

Her sentence supervisor, Colleen Geddes, became suspicious mid-last week when Wentworth wasn't in her home, like she was supposed to be, between 5 p.m. and 8 a.m.

The next day, Wentworth was tested and found with the drugs in her system.

At the time of her sentence, territorial Judge Heino Lilles noted there would likely be slips.

That's why he was willing to give Wentworth a second chance today.

She was to return to her home today and continue attending Narcotics Anonymous sessions and courses at the Yukon College.

The judge had the option to force Wentworth to spend the rest of her sentence at the Whitehorse Correctional Centre (WCC), which he did not exercise.

Upon breaching her sentence, Wentworth had to spend the weekend in jail, while her support workers gauged her sincerity in wanting to change.

Her lawyer, Gord Coffin, said the time behind bars was also a chance for Wentworth to get a taste of what WCC is like.

In anticipation of getting out, before court got underway this morning, Wentworth asked a woman she knew in the gallery for $2. She needed the money to take the bus home.

Wentworth told the judge she intentionally sought the drugs out to help her deal with her pent-up emotions.

The 18-year-old said she was sorry for the breach, but Lilles said being sorry isn't good enough.

'You can spend the rest of the sentence in WCC being sorry,' said Lilles, raising his voice.

He reminded Wentworth that the conditional sentence was a period of custody to be served from her home.

'It's not probation. It's jail. It's intended to be strict,' he said.

In her sentence, Wentworth was ordered to answer her phone in the evenings, so Geddes could ensure the young woman is abiding by her curfew.

Wentworth hasn't been picking up the telephone because of other harassing phone calls she's been getting from someone in the drug community.

'That's why we told you to get an unlisted number. It was to provide you with that kind of protection,' said Lilles.

'The only way he could have gotten that number is from you. That was very poor judgment on your part.'

Wentworth was ordered to have no contact with any known drug traffickers or users.

'I can't enforce that,' said Lilles at the time of her sentencing. 'You have to enforce that. It's a very important term because you know that peer group is going to be a disaster to you.'

If any of those people are harassing her, Lilles told her, she should tell Geddes immediately instead of not answering her phone.

Wentworth had to do her college homework from prison to make up for the couple of days she missed while serving time at the WCC.

Geddes noted Wentworth can't be skipping school if she has a bad day. Attending college is part of her sentence.

Also as part of her sentence, Wentworth must abstain from unprescribed drugs and alcohol.

She is only permitted to get prescribed drugs from one doctor and is only able to use one pharmacy. All other pharmacies were ordered not to fill her prescriptions

Lilles based the sentence on what Wentworth wanted for herself. He also founded it on research that showed recovering addicts need structure.

Geddes and the rest of Wentworth's support team said they are only willing to help if Wentworth is willing to abide by the rules and put an honest effort into turning her life around.

At the time of the robbery, Wentworth told the cab driver she would kill 'if it came to that.'

Lilles noted at the time of the robbery Wentworth didn't even need the money, because she already had cash.

The robbery was a result of Wentworth's drug addiction.

Wentworth's conditional sentence will be followed by a 12-month probation period.
