Demi Moore was rushed to the hospital after inhaling a "dangerous amount" of nitrous oxide, according to TMZ.
The site claims a friend called 911 after the 49-year-old actress went semi-unconscious from doing whip-its.
A whip-it (aka laughing gas or nitrous oxide) is commonly used by younger people who are looking to get a quick high.
A source tells Radar that Moore is being treated for anorexia, as well.
Moore will also no longer make a cameo in the Linda Lovelace biopic Lovelace, according to Deadline. The actress was set to play the role of feminist activist Gloria Steinem.
Moore and Ashton Kutcher split last November after six years of marriage. The Two and A Half Men star allegedly had an affair with San Diego native Sara Leal.
