Under cross examination Wednesday morning, Levounis conceded that he never saw evidence that Jackson injected himself with narcotics, ever sought or used illegal drugs such as cocaine, meth or heroin, or abused drugs to produce euphoria or get high.
There was also no evidence Jackson used more painkillers than doctors prescribed, he said.
Jackson lawyers have never disputed the singer's drug dependence. In fact, they contend that AEG Live executives, including one who was Jackson's tour manager when he entered rehab, were negligent for paying a doctor $150,000 a month just to treat Jackson. The high salary created a conflict for the debt-ridden Murray, making it difficult for him to say no to Jackson's demands for drugs.
Paul Gongaware, the AEG Live co-CEO who was in charge of Jackson's 2009 "This Is It" tour, was also tour manager for his "Dangerous" tour in 1993. Levounis acknowledged in testimony Wednesday that there was evidence that Gongaware knew about Jackson's painkiller addiction 15 years before his death.
Levounis' testimony about the dangers of a doctor being too friendly with an addicted patient, which he said Murray was, could help the Jacksons' case.
"A very close friendship between an addicted patient and a doctor is problematic," Levounis testified. "It makes it much easier for a patient to ask for drugs and it makes it more difficult for a provider to resist."
The medical records of Murray's treatment of Jackson between 2006 and 2008 -- when the singer lived in Las Vegas -- showed no painkillers prescribed during seven visits. Murray's notes did show he treated Jackson's complaints of insomnia with a sedative in 2008.
