Paula's statement in the article by Brittany Feagans was this regarding drugs:
[The people she was with] like to party, and I think it all stems from drugs, she said. Ive tried to tell these people that do drugs that I dont really care about the drugs. I dont care what youre putting in your veins or down your throat. I want Christina, and I want you to tell me things. Then you can go back to popping your pills or whatever.
What I don't understand is if they are told we don't care about your drug use, why wouldn't they tell what happened and help us find Christina? That is what doesn't make sense to me at all.
