McGowan is accused by Virginia Commonwealth prosecutors of felony possession of a controlled substance after a wallet she left behind on a January 20 flight to Washington Dulles International Airport on her way to the Women's March was found containing two small plastic bags with white powder that tested positive for narcotics, according to the warrant.
And now, the former "Charmed" star - who was later released on $5,000 bail - insists that despite handing herself in, she intends to prove she is innocent when the case goes to court.
The charges against the actor stems from a police investigation into her personal belongings which she left behind on a flight early this year.
After disembarking, Rose noticed her wallet was missing, and proceeded to file a lost-luggage claim to help recover the lost item.
Over the last several weeks, McGowan has become a leading voice against embattled movie mogul Harvey Weinstein, who has been accused of a range of sexual misconduct, from harassment to rape, by more than 80 women.
McGowan told the New Yorker in a Tuesday article that she did not respond to the February warrant for months out of worry she was being followed by people Weinstein had hired.
Police are investigating in Los Angeles, New York and in the United Kingdom, where seven women have told officers they were sexually assaulted by Weinstein between the 1980s and 2015.

It was recorded in the collection of King Charles I of England in 1649 but was auctioned to the Duke of Buckingham in 1763. CNN said the Salvator Mundi was sold at an auction in London in 1958 for just $59 because it was dismissed as a copy.
McGowan said she plans on fighting the charges.
Farrow, in addition to corroborating his sister Dylan Farrow's claims that his father Woody Allen molested her, has been reporting extensively on Weinstein's actions.
The 44-year-old handed herself into police in nearby Loudoun County, Virginia, on Tuesday after an arrest warrant was issued. She says she felt wary of the officer and was paranoid about possibly being followed by Weinstein's private detectives.
According to The New Yorker, an anonymous source associated with the Weinstein Company said that Weinstein privately discussed leaking the story of McGowan's arrest warrant in September.
McGowan has alleged that the cocaine may have been planted in an attempt to discredit her. I have been maligned, and you know what?
'I was going to but then things started to get really weird.
McGowan said that isn't into cocaine but that marijuana is her "jam".
