Adelaide’s Cassie Sainsbury releasing a new book, Cocaine Cassie, about her ordeal in a notorious Colombian prison

The convicted drug smuggler is turning the page with a new book about her ‘unimaginable’ ordeal in an infamous Colombian prison.

Convicted drug smuggler Cassie Sainsbury has written a book about her “unimaginable” ordeal in an infamous South American prison.

The Adelaide personal trainer says Cocaine Cassie will allow readers to “walk in her shoes as a prisoner in one of the most notorious prisons out there”.

“I’ve been keeping a secret from you all… and I’m finally ready to share it. It’s taken me four years to write this and to be okay with sharing my experiences in a very dark world,” she captioned an Instagram post.

“This journey is a way to deal with my traumas and to be at peace with some pretty unimaginable things.”

Sainsbury spent three years behind bars after being caught with a suitcase containing 5.8kg of cocaine in Colombia in April 2017, just minutes before she was due to board a flight home to Australia.

Last year she revealed she was raped during her time in Colombia’s El Buen ­Pastor jail and was sure she wouldn’t make it out of there alive.

“I was almost sure that someone would kill me there,” she said as a contestant on Seven reality show, SAS Australia.

“It was such a horrible feeling that I gave up all hope. I had a lot of time to kind of process having been manipulated and tricked by someone I thought was my friend … having been raped.”

Sainsbury said she also saw fellow inmates committing suicide.

In a September 2023 interview with The Advertiser, Sainsbury revealed she had been diagnosed with post-traumatic stress disorder, as the physical and mental scars from her ordeal in a Colombian prison continued to haunt her.

“It hit me quite hard, it was completely unexpected. I thought I was okay and then … I was having nightmares, I was reliving everything I went through in the last seven years,” she said.

It’s been two years since Sainsbury returned home to live in Adelaide alongside wife Tatiana, whom she met through mutual friends in a Colombian nightclub in 2021.

Sainsbury, who once owned a gym on the Yorke Peninsula, has since launched her own online fitness program, Cassie Leigh Fitness, with help from Tatiana.

The program helped Sainsbury drop a massive four dress sizes in five months.

Cocaine Cassie will be released on October 15.
