Cork woman Vera Twomey has said medicinal cannabis she got on prescription for her daughter in Spain has been taken by customs officials at Dublin Airport.
Ms Twomey has been campaigning on behalf of her daughter Ava, who has a rare form of epilepsy, to get access to medicinal cannabis in Ireland.
Yesterday she travelled to Barcelona where she obtained a prescription for cannabis oil.
She was accompanied back on a flight from Spain by People Before Profit TD Gino Kenny and MEP Luke Flanagan.
However, the substance was taken from her and she was held by Customs officials for about an hour at the airport.
She described today's events as a complete injustice and said she is not doing anything wrong.
Last month, she met Minister for Health Simon Harris after she took the journey from her home in Cork to the Dáil by foot and in a wheelchair in protest at the situation.
In a statement the Department of Health says it remains open to the Minister for Health to consider granting a licence under the Misuse of Drugs Acts where the proposed course of treatment has been endorsed by a consultant.
But Ms Twomey says the compassionate access programme is not sufficient for families like hers.
She says nobody in Ireland has got a consultant to sign for medicinal cannabis and has called on Mr Harris to do something about the situation.
