A 19-year-old from Staten Island, New York, has been jailed in Russia after she was caught with marijuana while on vacation with her mother.

Audrey Lorber was arrested at Pulkovo Airport in St Petersburg when Russian agents found 19 grams of marijuana - worth about $375 - on her person, according to a statement from the Moscow District Court of St Petersburg.

The teen has a prescription for medical marijuana in the US, which she showed to the agents. However, the Russian court said the prescription 'does not apply to the territory of the Russian Federation'.

The statement did not specify when Audrey was arrested but she is believed to have been in custody for at least two weeks.

She pleaded guilty to the charges and is now awaiting trial, according to the statement.

Audrey Lorber, a 19-year-old from Staten Island, New York, is being held in a Russian jail after agents at a St Petersburg airport found marijuana in her possession. Russian officials have not disclosed when Audrey was arrested, but she hasn't posted on social media since July 22, when she shared an Instagram photo (above) with her mom, Rochelle Lorber, in St Petersburg

Audrey's most recent Instagram post, dated July 22, shows her touring St Petersburg with her mom, Rochelle Lorber.

The pair are seen giggling at the edge of the Gulf of Finland, blissfully unaware of the legal trouble ahead of them.

Audrey's supervisor at Waterside Restaurant in Tottenville told the New York Post he talked to Rochelle two weeks ago as the mother was desperately working to get her daughter out of jail.

'She's hysterical,' Joey Guli said of Rochelle, a retired New York City school teacher.

'She moved out there and got an apartment just to try to get [Audrey] on house arrest, but they didn’t give it to her.

'It's disgusting what they did. They are trying to throw the book at her.'

Guli described Audrey as a stellar employee who has worked at Waterside for several summers in between terms at Pace University in New York City.

The film major is attending the school on scholarship and maintains a 4.0 grade point average, Guli said.

'She has a career ahead of her and wants to be in the movie industry,' he said. 'All my customers love her.'

Guli noted that he has never seen Audrey smoking marijuana or visibly high. It is unclear why she has a medical marijuana prescription.

Audrey's mother Rochelle shared several photos of their European adventure on Facebook. the teen's supervisor at Waterside Restaurant in Tottenville, New York, said he talked to Rochelle two weeks ago as the mother was desperately working to get her daughter out of jail

Russian officials said Audrey said the cannabis she was caught with in St Petersburg had been purchased in the US and that she used it for 'personal consumption'.

A US State Department spokesperson issued the following statement about Audrey's situation to DailyMail.com on Sunday: 'We are aware of reports of a U.S. citizen arrested in Russia. Whenever a U.S. citizen is arrested overseas, we stand ready to provide all appropriate consular services. Due to privacy considerations, we have no further comment at this time.'

Russia imprisons more people per capita for drug crimes than any other nation in Europe, with roughly one fourth of all prisoners jailed for drug-related offenses, according to the Moscow Times.

Most arrests - including Audrey's - are under Article 228 of the Russian Criminal Code. In 2018, 100,000 people were arrested for that charge, which carries a maximum sentence of three years.

Earlier this year American-Israeli citizen Naama Issachar, 25, was arrested in Moscow and charged with smuggling nine grams of marijuana into Russia.

Issachar was detained in the airport ahead of a connecting flight from India to Israel via Moscow. Her trial was set to start last week after more than four months in custody.

Despite its strict enforcement of drug laws, Russia allowed attendees of the 2018 World Cup to bring heroin, cocaine and marijuana into the stadium as long as they had a doctor's note written in Russian.

Audrey is currently studying film at Pace University in New York City
