'Bill Cosby Show' dad, actor and entertainer Bill Cosby, has been accused of drug assisted sexual assault by 50 women.The list includes models Beverly Johnson, Jewel Allison, Lilli Bernard and Janice Dickinson along with several others.

Latest reports suggest that Bill Cosby had allegedly used his mistress and wife Camille Cosby to obtain the prescriptions for Quaaludes from Dr Macyln Wade, a gynecologist in Beverly Hills. Dr Macyln was the former head of obstetrics and gynecology at Cedas-Sinai Hospital, reported Mirror.

Vicki Hufnagel, a resident at the hospital claimed that she witnessed the physician write out a prescription while Cosby's wife Camille and his mistress were there for an appointment.

"As soon as she (his wife) left, (Bill Cosby) began thanking Dr Wade for making the arrangements for him," Vicki told RadarOnline. She added,"Dr Wade told Bill that it wasn't any problem, seeing both his wife and girlfriend at the same time... And then they both laughed."

Vicki also claimed to have seen the prescriptions for Quaaludes, while she was working at the hospital.

"She was also on bad terms with Dr Wade - who died in 2001," reported Mirror. "(She) brought a suit against him (Dr Wade) in 1985, claiming she fired him after she ended an affair."

In a 2005 deposition, Cosby who played 'Bill Cosby Show' dad admitted that he got seven prescriptions of Quaaludes from a doctor in Los Angeles. Cosby told that he took the drugs for a bad back.

"(The) court documents reveal the doctor (Dr Wade) knew he (Bill Cosby) wasn't just taking them for himself," Mirror reported.

"It was considered a party drug called 'disco biscuits' and it was something that was done frequently, not just by Mr. Cosby but other entertainers," Monique Pressley told Good Morning America.
