A former Burnie woman tucked part of a $40,000 amount of the drug ice in her bra, the Launceston Magistrates Court heard.
Monique Gracen Lester, 25, now of Western Australia, has pleaded not guilty to trafficking in methylamphetamine and to dealing with $1250 which was suspected of being the proceeds of crime.
The charges, which would normally be heard in the Supreme Court, went ahead in the lower court at the request of defence counsel James Kitto.

Mr Kitto said that Ms Lester had no knowledge of the largest bag of ice and the rest was for personal use.
Crown prosecutor Jennifer Slevin said Ms Lester was driving her maroon Holden Cruze along Westbury Road, Prospect, about 10.50pm on July 17, 2018, when she was pulled over by Constable Michael Poxon in an unmarked car.
Constable Poxon requested help from a female officer to conduct a search after she recorded a positive drug test.
Constable Kelly Hindle said she had seen a ziplock bag poking out of the left cup of Ms Lester's bra area.
"I asked what it was and she told me it was her nipple," Constable Hindle said.
"I said it wasn't her nipple and she said it was her nipple."
Constable Hindle said she removed the bag containing ice and Ms Lester told her it was bath salts.
Constable Poxon said the search found two glass smoking pipes, digital scales and unused ziplock bags.
A wallet contained $200, and there were several loose $50 notes in the console and $500 in Ms Lester's handbag-a total of about $1850.
Ms Lester told Constable Nathan Slater on the night that she had withdrawn the money at an ATM.
However, from the witness box on Wednesday Ms Lester said she had sold two rings to a friend for $2000.
An attempt to tender a letter from the friend acknowledging the transaction was objected to by the Crown, and refused by Magistrate Simon Brown, because the writer was not available for cross-examination.
Mr Brown heard that five sealed items found in the car contained amounts of ice varying from 0.03 grams to 27.8 grams for a total of 38.3 grams.
In a video recorded interview, Ms Lester said "no comment" to all questions relating to her movements on the night.
Forensic scientist Carl Grosser said Ms Lester's DNA was found on the digital scales.
Mr Grosser said Ms Lester was also the strongest contributor of DNA on a ziplock bag.
Cross-examined by Mr Kitto, Mr Grosser said a wallet found that a man had left DNA.
Ms Lester told the court that she had lent her car to that man for about 20 minutes on the day of the search after she picked him up from the Airport.
Detective-Sergeant Glenn Evans said the ice could have been worth up to $40,000 if sold in "points" - the 0.1 gram amount commonly purchased by users.
He said users rarely bagged their own drugs and that the bag sizes were larger than a user would normally carry around.
Ms Lester said the bag of drugs in her bra was given to her by Mr Davies for personal use.
"It was given to me for personal use and I had no intention of trafficking," she said.
Cross-examined by Ms Slevin about why she told police the bag was her nipple she replied: "I don't think it was a lie, my nipple was there."
She said she was high on the night and very nervous.
Ms Lester disagreed that the ice, scales and cash was hers for trafficking.
Ms Lester is required to prove on the balance of probabilities that she did not intend to traffic.
Mr Brown adjourned the case for decision on July 28 at 3pm.
