A Utah woman says she has buyer's remorse after finding cocaine in a box of recently purchased tampons.

Cindy Davidson, 39, told Salt Lake City police she bought the box of Boots tampons from NPS, a discount store that sells misdirected or damaged freight products, CBS News reported.

However, when she opened the sealed box she said two of the 16 tampons were replaced with a white powder wrapped in cellophane, Salt Lake City TV station KUTV reported.

"I started getting nervous because I thought it might have been a terrorist attack," she told Salt Lake City TV station KSL. "I called my sister first and said I was going to call the manufacturer the next day and she told me to call the police."

According to KUTV, police tested the substance and confirmed that it was cocaine.

NPS officials said they purchase their items from auctions and that they have no clue where the cocaine could have come from.

"Without knowing the customer, without knowing the product specifically on this situation we just have no information to try and figure out where it came from," Stan Alexander, NPS director of security, told Salt Lake City TV station KTVX.

Davidson said the whole situation is crazy, and that she still can't believe it.

"I've never seen anything like that, so it was weird," she told KTVX.
