'She’d Stockpile Drugs So She Wouldn’t Run Out': New Details of Whitney Houston’s Drug Habit, Spent Thousands of Dollars a Week

Further reports of drug use have surfaced involving the late Whitney Houston.

The singer, who passed away on February 11 at age 48, reportedly returned to a life of serious substance abuse after claiming sobriety in 2010.

Most recently, The Daily Beast offered an even further in-depth look into the Grammy winner’s addiction through the years, with a friend of Whitney’s claiming the singer would “spend thousands of dollars a week buying drugs and stockpile it in the house so she wouldn’t run out."

So, why didn’t her friends and family step in?

“The family was afraid of the embarrassment on some level and wouldn’t confront her early on,” Monique Houston, who married Gary Houston and divorced him in 2001, tells the Beast. “Her mother would always say, ‘I don’t understand this drug thing.’ And she didn’t. They let it get too bad before they understood she needed serious help, and then it was too late.”

As for the assumption that Whitney was introduced to drugs by her ex-husband Bobby Brown, Monique says that isn’t the case. “Drugs were around her for years before she met Bobby and continued after he left. It was worse when they were together, but he didn’t cause it.”

Bobby reiterated this claim during his interview with Matt Lauer on TODAY this week. However, a close friend to the late singer spoke out about the couple’s tumultuous relationship and the ups and downs they shared while they raised their daughter Bobbi Kristina, now 19.
