Barry Lambert is gazing out the picture window of his Sydney home at a multimillion-dollar beach view. Around him his grandchildren fiddle on their phones while his wife Joy sips tea. Lambert drinks a cappuccino he's just bought at the local café. It's a charming family scene – except for one thing. At the table beside him, his son Michael is committing a crime that carries a sentence of up to two years' jail.
Michael, 44, takes out a tube that says "Hemp Oil 20 per cent CBD", squeezes it and smears the brown paste onto a corn chip which he then gives to his daughter Katelyn, who is draped sleepily on her mother Saowalak's lap. Katelyn, Lambert's four-year-old granddaughter, wakes briefly and chews on the chip.
