Six days later, she boarded a plane for New York to audition for a play.
Her stay in New York proved to be her downfall, as she found cocaine easily in nightclubs.
Shortly thereafter, a friend of Barrymore's and the friend's mother entered the house and whisked her into a waiting car.
Barrymore's second stay at the clinic was less effective in the long term than the first.
In March 1989, she went out to celebrate six months of sobriety.
She was already a regular at the notorious Studio 54 as a young girl, smoking cigarettes at the age of nine, drinking alcohol at age eleven, smoking marijuana at age twelve and snorting cocaine at age thirteen.
Barrymore later described this period of her life in her autobiography, Little Girl Lost.
Barrymore currently stars with Timothy Olyphant in the Netflix comedy series Santa Clarita Diet (2017).
