Former Olympic ice dancer Pasha Grishuk was drugged with GHB in a ritzy Orange County, California hotel on Tuesday.

Grishuk was attending a business meeting at the St. Regis Monarch Beach on April 12 when she evidently began to feel ill and numb.

When eating dinner, Pasha says she spotted a partially dissolved pill in the bottom of her drink. Investigators later found another dissolved pill in the bottom of a drink she ordered in the hotel's lounge.

Toxicology tests that came back Tuesday were positive for GHB, but no one seems sure how the pills got there.

"How somebody was able to do that, I honestly don't know, but it appears that somebody, for whatever reason, attempted to drug her," sheriff's spokesman Jim Amormino said.

GHB, or gamma hydroxy butyrate, is a common date rape drug. It can cause breathing problems, loss of consciousness, seizures, drowsiness, coma and death.

The U.S. Drug Enforcement Administration labels GHB a "predatory drug" that can be mixed with alcohol to reduce resistance from a victim before a sexual assault. It is also popular with teenagers at raves and is sometimes used by bodybuilders for its anabolic effects, according to the DEA.

The 36-year-old Grishuk is a Ukrainian native who now lives in Los Angeles. She won the gold medals for Russia in ice dancing in 1994 and 1998.
