Juanita Raynor, 35, appeared before Suffolk Magistrates’ Court charged with possessing a class B controlled drug, theft, and fraud by false representation.
The court heard that on Christmas Day, Raynor was found in possession of amphetamine in Ipswich.
The drug was seized and magistrates ordered its forfeiture and destruction under Section 27 of the Misuse of Drugs Act 1971.
On the same day, Raynor, of Gippeswyk Road, admitted stealing several items including an American Express card, a Lloyds Premier card, a Lloyds bank card, a Greater Anglia rail card and a Platinum cashback everyday card.
The value of the items was not stated.
Magistrates were told that Raynor then used the stolen bank cards at different shops in Ipswich to purchase miscellaneous goods for herself.
Raynor admitted all of the offences when she appeared before court on Boxing Day.
She was fined £80 for the fraud offence, while no separate penalties were imposed for the theft.
In addition, Raynor was ordered to pay £110 in prosecution costs.
