Melissa Reid, 20, from Lenzie and Michaella McCollum, also 20, from Dungannon, Co
Tyrone, face a maximum prison sentence of 15 years if convicted.
The pair have spent the last two weeks in custody over the drug trafficking allegations but are expected to be transferred to prison to await their trial.
They were pictured in handcuffs being escorted by officers from the National Police anti-drug headquarters for medical examinations.
Peruvian police said they found around 24lb of cocaine hidden inside food packages as the women attempted to board a flight from Lima to Madrid.
The women, who both deny the allegations, claim they were forced to carry the bags by armed men and are expected to enter not guilty pleas.
If refused bail, the women face up to three years in jail before their case comes to trial.
Ms McCollum’s lawyer,
Peter Madden said the women had been kept in harsh conditions but had been treated well.
“They are fairly tough conditions, there’s not an awful lot to eat there, but Michaella’s been treated fairly well by the police and by the people in the police centre,” he said.
Mr Madden said conditions facing the women were not good or clean. They had no blankets and were not offered any food.
Mr Madden said: “The conditions inside the holding cells are pretty grim. They are expected to lie almost on the floor. There is a sort of sponge bed which is not acceptable, it is not clean.
“They have not been offered any food. To me that is unacceptable.”
He said the two women had not been given anything since dawn as they were taken through the Peruvian justice system.
The women had travelled separately to the party island of Ibiza in search of work this summer and claim they were forced to travel to Peru under duress.
Before news of the arrests broke, Ms McCollum’s family, had launched an internet campaign, fearing she was missing.
Questions about their
version of events were raised following the emergence of photographs allegedly showing them posing on a balcony and on a beach with glasses of beer days before they were
arrested at Lima Airport.
