Cocaine? HELP?

Okay, first of all I do NOT do drugs. My problem started this morning, I was cleaning at work (a bar) and found a dollar on the floor, hey sweeper pay I thought. I pick it up and unfold it and shove it in my pocket. I sweep a little more and remember I still haven’t eaten my hashbrown from breakfast at McDonalds, so I go and grab it and eat it while I clean. My sinuses and allergy’s are acting up so I rubbed my nose about 15 times. Then my heart starts racing. I think I just need a break so I pull out my new found dollar and decide to go put it in the game. Well the dollar was covered in cocaine, I called 911, police, paramedics the whole 9 yards. I get rushed to the hospital, they tell me i’m having a bad trip and to just go home and ride it out. Now it’s 7 hours from time of incident and my chest hurts and I still feel the effects. Any suggestions on how to come down faster so I could go back to my normal life? I’m scared. I have never done drugs in my life, i’m 25.
The police tested it and it tested positive for cocaine. I know nothing about drugs so any help would work.
I am the manager of this bar, and my daytime barmaid called in sick so I had to clean. Well the amount of cocaine in this bill was alot. The bar is a gentlemens club and it looked as if someone had tipped one of my employees with a dollar and a gram or so of coke. I plan on reviewing security footage to see if I can pin-point who it came from. Right now I just want to fee good.
