Demi Moore’s late-night trip to the hospital Monday may have been the result of nitrous-oxide abuse, TMZ reports. Unnamed sources said that Moore was in her Los Angeles home doing “whip-its,” a low-quality street drug that typically involves inhaling the compressed gas used in whipped-cream cans, when she became semi-conscious. TMZ reported Tuesday that the 49-year-old actress was cared for by first responders in her home for half an hour before she was taken to an area hospital. Moore’s representative told TMZ that the Charlie’s Angels star, who split with husband Ashton Kutcher in November, was being treated for exhaustion. “Because of the stresses in her life right now, Demi has chosen to seek professional assistance to treat her exhaustion and improve her overall health,” the rep said.
