Cosby accuser Beverly Johnson speaks out on drug admission

Beverly Johnson told NBC on Wednesday she was far from surprised to learn of Bill Cosby's bombshell 2005 deposition in which he admitted drugging women he intended to sleep with.

One of the first women to come forward about Cosby's behavior, Johnson spoke bluntly to "Today" about a time she says Cosby drugged her coffee.

"After the first sip, the room began to spin. I was woozy. I took another sip and it increased from there," she said.

When Johnson realized she had been drugged, she says she got "survival instincts" – yelling and screaming until Cosby backed down.

Johnson says this new information doesn't make her feel vindicated, but that she hopes it will encourage women to use their voice in these types of situations.

"I'm very happy for the victims that they have some sense of peace and validation," she said.

The complete interview is available on NBC's website.
