Traces of cannabis were also found on a set of scissors and cannabis residue was found inside two coffee containers in the kitchen.
McVeigh had $140 cash in her pocket and the same amount of cash was found stuffed inside a tea container on the bench.
The cash was all in $20 bills - a cannabis tinnie usually sells for $20. Police originally charged McVeigh with possession of cannabis for supply but after a further investigation which included analysing her text messages the charge was reduced to possession.
McVeigh pleaded guilty to the reduced charge and breaching home detention.
Her lawyer Craig Horsley, said his client, who was remanded in custody just over a month ago, realised how foolish she had been not only because of her loss of liberty but the impact on her children who are living with separate caregivers.
She wanted to bring her family back together sooner rather than later, he said.
Judge Ingram said he was mindful of McVeigh's desire to be reunited with her family as quickly as possible but prison had to be the outcome.
"I have tried to make it clear as I can be in this court time after time to people with alcohol and drug convictions not to touch prohibited substances and not to abuse the other conditions of their sentence or be prepared to face the consequences.
Imprisonment must inevitably follow for someone on home detention for drug offending who re-offends in the way you have."
The judge said by imposing two months' prison on McVeigh - effectively a time-served situation - he was taking into account that she had been very near completing her sentence at the time of her offending and was still subject to post detention conditions.
