A British woman has returned from Dubai after spending eight weeks in jail for having codeine in her body.
Tracy Wilkinson was prescribed the painkiller for a back injury
Tracy Wilkinson, 43, from Balcombe, West Sussex, was cleared of wrongdoing on Sunday when it was proved the painkiller was prescribed in the UK.
The drug, banned in the United Arab Emirates, was found in her urine when she was held over a passport error.
Arriving at Heathrow she said there were times she thought she would never be freed and feared she could even die.
Mrs Wilkinson was freed when her GP provided the Emirates authorities with written evidence she was given the painkiller and temazepam for a back problem she was suffering.
When she arrived at Heathrow she said: "I can't describe how disgusting it was - the way I was treated, the way I was held.
"Obviously I missed my children, I missed loads of things.
"But you try and think 'I'm going home tomorrow' - which they promised me since virtually the third day I arrived there.
"In the end you think 'who's kidding who here - are you ever actually going to go home?'
"At one point they handcuffed me in this tiny cell for about six hours, I was handcuffed so I was kind of dangling and could not reach the floor.
"I thought I'm going to die here. I couldn't breathe."
After being cleared, she was told she might have to wait up to another 15 days for prosecutors to decide whether they would lodge an appeal but on Wednesday the prosecution waived their right to appeal.
The mother-of-two, a sports osteopath, had faced a four-year jail sentence if found guilty.
