In a new video Elizabeth Smart has revealed that pornography caused her kidnapper to become sexually aggressive and rape her in the nine months she was his captive.
The video, released by Fight the New Drug, an anti-pornography movement, was published on Friday.
In the five minute clip, Smart begins by reliving her 2002 kidnapping at the age of 14.
A montage of news coverage flashes on the screen as Smart, now 28, tells how her captor Brian David Mitchell took her from her bed and her home.
She begins to explain the abuse and goes on to say that she was frequently raped by Mitchell.
Smart says these rapes were highly exacerbated by Mitchell's use of pornography and that her kidnapping in the first place was due to his obsession.
"It just led to him raping me more, more than he already did, which was a lot.
"Looking at pornography wasn't enough for him.
"Having sex with his wife after looking at pornography, it wasn't enough for him.
"And then it led him to finally going out and kidnapping me.
"He just always wanted more. I can't say that he would not have gone out and kidnapped me had he not looked at pornography.
"All I know is that pornography made my living hell worse," Smart says in the video.
In the 13 years since Smart was returned to her family, she has become an advocate against abuse and against pornography.
"I have gone on to become an advocate for abuse prevention, an advocate against pornography.
"I witnessed firsthand just how damaging it is. When I take a step back and I look at my life as a whole, I have had a pretty incredible, wonderful life and I wouldn't trade it for anything.
"I'm happy now and I couldn't imagine my life any different from how it is now," she says.
