A court was told Justine Siebenaler would no longer be able to pursue a career in law after being convicted of having Class A drugs.
Siebenaler, 26, wept in the dock yesterday as a security officer described how she pulled two bags of drugs out of her underwear during a search.
Tina Spence, 34, was carrying out searches on people entering the music festival when Siebenaler and her friend raised suspicions by behaving oddly.
Ms Spence said: "They were acting very suspiciously. They wouldn't look us in the eyes. I told her I had suspicions and that what I was going to do was get the police.
"I said to her the best thing to do was to tell me what she had. She pulled bags from her trousers, from her underwear, and showed me what she had in the bags. There were five pink tablets and a substance that looked like herbal cannabis. She was starting to get upset and was crying.
"I told her we had had a briefing before T in the Park with G4S Security and we were told these pink pills were killing people before T in the Park, so if anyone was found with them we had to inform the police."
Ms Spence added: "She told me she was taking them in for her brother. I handed the drugs over to the police. She started telling the police they were hers."
Ms Spence told Perth Sheriff Court: "I remember her sitting and crying and telling me she was a law student. She was sitting for 10 minutes asking me not to call the police."
Fellow security officer Charlene Baird, 24, said: "We did have suspicions that drugs paraphernalia were present. She said they didn't have anything on them.
"We advised them the police would have to be called because they had refused a search. The female came forward and pulled something from her trousers. It was a bag of pink pills and also a bag of cannabis. She said she was studying to be a lawyer and stated this could go against her. She started getting very upset."
Siebenaler, of Argyle Street, Glasgow, was found guilty of possessing ecstasy at T in the Park at Balado Farm Estate, Kinross-shire, on July 9 last year. A second charge, of possessing cannabis, was dropped by the Crown. Solicitor David Holmes, defending, said Siebenaler had recently graduated in law but that career path would "now be closed to her" as a result of her conviction.
Sheriff Eric Brown said it would be a matter for the professional body to decide and he fined Siebenaler £200.
Siebenaler had tried to have the case against her thrown out when witnesses failed to turn up to give evidence but the bid was rejected by another sheriff.
