Janet Jackson says her entire family recognized her brother Michael had a drug problem, and tried to help, but she insists the King of Pop wasn’t ready to acknowledge he had a problem.

“You can’t make ‘em drink the water,” Jackson tells ABC News in an interview airing Wednesday.

“Of course (we intervened). That’s what you do. Those are the things that you do when you love someone, you can’t just let them continue on in that way and we did (try an intervention)… a few times… we weren’t very successful.” She adds, “(He) understood that it was (out of) love, because of caring, but when it’s something like that (drug addiction), people can tend to be in denial.”

Michael Jackson passed away June 25 after a powerful overdose of the prescription drug anesthetic Propofol.
