Nicole Taylor, 25, of Kershaw Street, Chorley, was sentenced at Preston Crown Court after an investigation by police.
In 2020 Taylor became the power of attorney after her grandfather’s health deteriorated and he was put in a care home.
She was asked to look after his home in Preston and was told she could use his bank card to pay for repairs or bills.
In a year, Taylor spent a total of £37,363.63 on mostly takeaways, tattoos and cash withdrawals, believed to have been spent on drugs, with her later admitting she had a drug problem.
The victim’s family became aware of the thefts, producing bank statements which were taken to police.
Taylor was given a summons to appear in court for the offence of theft. She pleaded guilty and was jailed for 14 months.
