<human>: Can you condense the text into a few key points?

Recently, I was hit over the head with a bottle while at a rave. I vaguely know the guy who hit me; he's someone who I went to school with who has pretty serious anger problems and does not like me because we dated the same girl.

That night, I went to the ER and got stitches (my wounds weren't too serious, fortunately, though injuries from a glass bottle can get really bad). The next morning, I called the cops and filed a police report. I plan to press charges at least to some degree; mostly, I'm worried that I might run into this guy again and I don't want to have to worry about that.

Here's the catch. The police are currently investigating, and asked for my medical records from the ER. I had taken mdma (molly) the night of the rave, and had noted this at the ER. (Though I was not rolling very hard, it was obvious that I had taken some drugs due to my massive pupils, and I figured honesty was the best policy). The hospital records note that I said I had taken mdma.

Should I be worried about getting in trouble for the drug use? Should I send the hospital records to the detective to assist the investigation of my assault, or is it too risky since they say that I used an illegal drug?
<bot>: Got hit with a bottle while on molly, want to press charges, cops want the hospital report that says I was on molly.
