A CAIRNS couple accused of using foreign drugs in a home abortion have been found not guilty after trial which sparked debate over Queensland's 111-year-old abortion legislation.

Police allegedly found three empty blister packs containing traces of the drugs in a walk-in wardrobe during a search of the couple’s Mount Sheridan home on February 1, last year, the Cairns Post reports.

Although the blister packs were empty, a Queensland Health forensic scientist told the court that upon testing, each was found to contain small traces of the drugs.

Constable Megan Johnston told the court she was standing by the kitchen table with the young couple when another officer emerged from a bedroom with the empty blister packs, a quantity of white tablets and notes written in a foreign language.

The court also heard there was no medical documentation confirming Ms Leach was pregnant in the first place.

Three general practitioners from the Cairns 24-hour Medical Centre said they gave referrals to Ms Leach for her to get blood tests and an ultrasound to confirm the pregnancy however, they never received the results.
