But it's now come to light that the aspiring fashion designer had three different kinds of drugs in her body including cocaine, xanax and cxycontin, according to the BBC . Coroner Shirley Radcliffe described the combination as "the perfect storm".

According to the BBC , it's been revealed that Flicit had a history of "recreational drug use over the years" which increased after her mother's death in 2016. Flicit was persuaded to complete a successful stint at an Egyptian rehab facility in Autumn 2018, but reportedly relapsed in 2019.
