He faces a felony charge of administering a drug with the intent of having sex. Halstead and Grishuk were having a business dinner at an Orange County hotel last month.
Grishuk says she suddenly felt like she was going to die then discovered a partially dissolved pill in her glass of wine.
"Through my whole body I started getting the shakes and my lips started getting numb," recounts Grishuk.
Grishuk saved what was left of the pill, and she was taken to the hospital.
The drug was identified as Nimetazepam, which is similar to the date rape drug GHB.
Halsted never admitted putting the drug in her drink, but did admit taking Viagra in the hotel restroom.
