Huffing or Photographing?

Sunday night, my friends and I decided to do a nude photo shoot. It was pretty spontaneous but being the art and photography freaks that we were, we went with it. Jeff spray painted words onto my back and Courtney's back, and we showed it off. Ben photographed digitally to enhance his portfolio, and Jeff was the monkey (the one who does all the dirty work the photographer can't). After we finished the shoot, Courtney took a shower to get rid of the paint and I was sitting in my room wrapped in a towel, waiting to get in the shower. I got a knock on my door, opened it, and saw 3 police officers. I was so shocked and had no idea what I did wrong. But apparently my roommates and other people in the building had smelled the paint and thought we were in my room huffing it. They didn't knock on the door, didn't call, didn't say a word to me or tell me how they were feeling. Instead, they had called the police. Luckily, the police thought this was just funny and didn't press any charges. They all just laughed and checked our I.D.s.
I apologized to my roommates, but didn't get a very positive response. I guess I really screwed up on this one.
