Roofies - Should I report?

It was apparent that I had roofies put in my drink last night. i took a sip of a drink, and 10 minutes later, i couldnt stand. I blacked out for about 8 hours. Is there a point in getting tested to make sure? My friends watched over me the whole night because they knew that 2 cups of beer couldnt possibly make me fall over like that. Is it a waste of money to get tested just to see if it was roofies? I was at a frat at my friends school. there would be no way of tracing the guy who gave them to me anyway.
