<human>: Condense the text into a few key points

This happened a couple of nights ago. It has been pretty stressful this last week, so I toked a little before making dinner, which I never do. A little went much further than expected. I was eating dinner with my roommates and we heard tires squealing and then a very loud bang, and I ran outside calling 911 to get emergency services there.

My roommate ran down to see if he could help the guy, and the guy was completely shitfaced walking around outside of his car, which was destroyed beyond recognition. 

I had quit smoking cigarettes but the police officer wanted to ask me about what I saw/heard once they got done with getting the car out of the ditch, so I started smoking my roommates cigarettes to get the smell of weed covered up a bit.

I think he knew that something was up, but that also could just be common paranoia. The guy that was in the accident refused medical attention and was taken to jail.
<bot>: Drunk driver ran a stop sign going into a main highway, screeched into a downhill embankment and hit a tree, I was asked by the police for a statement while high since I called the emergency services.
