Temple University academic advisor Marguerite Jackson maintains she knows Andrea Constand isn't telling the truth about her alleged 2004 encounter with Cosby.
However, the defense team's toxicology expert, Dr. Harry Milman, spent an extended amount of time reading from the back of a Benadryl box and its warnings. The company's website shows that an "allergy plus congestion" variety now comes in blue.
Jurors could soon hear Bill Cosby's testimony about giving Quaalude (Mandrax) to women before sex. Rohrig said they made people act intoxicated while Milman said they could not make someone black out immediately, as some of Cosby's accusers described from the witness stand last week.
Cosby, 80, says any sexual contact with Constand was consensual.
Cosby, best known as the star of the 1980s TV hit "The Cosby Show", is being retried in a Pennsylvania court on charges of giving three blue pills to Andrea Constand and raping her at his home near Philadelphia in 2004.
But a different expert called by Cosby's defense team said she couldn't have felt those symptoms so quickly or severely from the Benadryl that Cosby said he gave her. They got to talking about Cosby after the comedian offered to buy her a drink and promised, "I won't put anything in it", she recalled.
Kimberly Harjo, a former executive assistant for the Brokaw Company, testified about itineraries she prepared for Cosby in late December 2003 for his events in January 2004.
Mesereau said Russell has knowledge that Constand was "addicted to magic mushrooms", and frequently smoked marijuana during his friendship with her between 2000-01.
Cosby said he gave Constand 1½ tablets of the cold and allergy medicine Benadryl to help her relax, then fondled her breasts and genitals, according to the police transcript, which also was read to the jury on Tuesday.
Constand said Cosby knocked her out with the pills, penetrated her with his fingers and guided her hand to his penis.
Cosby, in a 2005 deposition read to jurors by a police detective, said he obtained seven prescriptions for quaaludes from his doctor in Los Angeles in the 1970s, ostensibly for a sore back, but added he did not use them himself because they made him exhausted. The jury has also heard Cosby's own statements admitting that decades ago he obtained Quaaludes to give to women before sex.
Prosecutor M. Stewart Ryan, during cross-examination, said Montgomery County District Attorney Kevin Steele prosecuted a drug case in 2002 that resulted in the seizure of thousands of illegal Quaaludes.
Alcohol, Rohrig said, would intensify the effects of Benadryl. Cosby paid Constand almost $3.4 million in 2006, and his lawyers call her a "con artist" who set him up. They said she'd show that Constand "could not have been the unwitting victim" prosecutors have portrayed.
Cosby's lawyers lost their fifth bid for a mistrial over the prosecution's treatment of Jackson. Jackson told Cosby's lawyers she was Constand's roommate for more than one road trip with the team.
Ryan highlighted differences between the January 22 affidavit and one that Jackson wrote on her own past year, getting Jackson to concede that Cosby lawyer Kathleen Bliss had her add quotes and make other changes to the second document.
Judge Steven O'Neill said there were "simply no grounds for a mistrial". He added that it didn't appear the defence did anything wrong, nor were prosecutors wrong to question their involvement.
But, that same man, who said he was "more than a close friend", also testified he didn't even know Constand had moved to the United States or worked at the college.
