Reformed Miss USA Tara Conner admits to PEOPLE that she used cocaine and tried nearly anything and everything under the sun before checking herself into rehab two months ago.

“Cocaine was one of the drugs that I did use. It’s hard to look back at that,” she tells PEOPLE in its new issue. “I was an equal-opportunity [user] – I would try anything once.”

It was alcohol, she says, that had the biggest hold on her. Citing a family history of alcoholism, Conner says that for many years she was “a functioning alcoholic. If I got caught [drinking], I would stop – I was able to do that.”

Now the countdown until Katie Rees enters rehab begins.
