In a shocking testimony in an inquest into the death of Daniel Smith, Anna Nicole's son, Larry Birkhead testified to the court that the late 20-year-old was a frequent drug abuser.

According to Larry, Daniel and his friends stole methadone from Anna Nicole in April 2006, which the former Playmate discovered after watching her surveillance cameras.

Daniel passed away on Sept. 10, 2006 from an accidental overdose of methadone, Zoloft and Lexapro. Until now, it was unknown as to how he obtained the methadone, a drug that was prescribed to Anna Nicole while she was pregnant with Dannielynn, now 18 months.

In addition, Larry was also questioned about his old claims that he witnessed mother and son smoke marijuana with Howard K. Stern, to which the 35-year-old photographer admitted he wasn't completely sure about what he saw.

What he was sure about was Daniel's change in behavior. Anna Nicole's first-born suddenly became hostile at the start of 2006, incessantly partying and once even tossing a television out the window.

Howard K. Stern testifies on Tuesday.
