Mac is surrounding himself with junkies and lowlifes. Its a real tragedy, a source is quoted by the Enquirer as saying.
Another friend said those close to Culkin were afraid for him.
Macaulay Culkin is surely dying. Hes addicted to heroin, oxycodone, Percocet and Vicodin, they said.
I have witnessed his drug taking, which has escalated over the past year and a half to the point where he needs serious help.
Mac is still partying hard. I pray that he finds the courage and strength to clean up before its too late.
Culkins publicist, Michelle Bega, last night issued a statement saying the allegations were false.
The report in the National Enquirer that Macaulay Culkin is addicted to heroin and assorted hallucinogenics is not only categorically without merit, but it is also impossibly and ridiculously fictitious, she said.
Culkin started acting when he was four. Six years later, he starred as Kevin McCallister in Home Alone.
The film became an enormous box office success, propelling Culkin on to the A-list.
He was said to have been paid £70,000 ($NZ133,000) for the first movie, but that shot up to £3million (NZ$5.7m) for Home Alone 2, filmed two years later. At the age of 14, however, Culkin retired from acting.
At 18 he married childhood sweetheart Rachel Miner, but they divorced four years later. Culkin also became embroiled in a bitter court battle with his parents over the handling of his Home Alone fortune.
In 2004 he was arrested for drug possession, and in 2008 his sister, Dakota, was killed in a car accident.
He returned to acting as an adult, but never achieved the same success.
