Though it may be weeks until Casey Johnson‘s toxicology reports reveal what caused her death, RadarOnline.com has learned new details about the heiress’ drug-fueled final months.
Her friends have come forward to reveal the sad story of a vivacious but out-of-control woman who needed help but consistently refused it.
Johnson was taking a cocktail of prescription drugs along with snorting cocaine and partying almost every night of the week. No one knows yet if drugs killed her but all of her close friends know that she was abusing them badly months before she died.
RadarOnline.com has learned exclusively that in the last year of her life (and well before that), the heiress was using Oxycontin, Klonopin, Valium, Xanax, Ativan, cocaine, marijuana and Ecstasy.
Her closest friends are now wracked with guilt that they couldn’t stop her and watched her party lifestyle destroy her.
“I saw Casey do cocaine at least two times, and she was often mixing cocaine with the prescription drugs. She always had a dazed look about her,” a source who knew Johnson for more than 10 years told RadarOnline.com exclusively. “She went out five, six or seven nights a week.”
After partying with cocaine, Johnson would crash and sleep 16 hours straight, sources told RadarOnline.com.
One source revealed, “Casey was manic and she would stay up all night long ordering prescription medication over the internet. The drugs she was ordering, without a prescription, and that she was taking were Oxycontin, Klonopin, Valium, Xanax, and Ativan.”
She was also using marijuana and ecstasy.
