Ok, so I'm over 21 and I was visiting some guys I know. They are all 18 or older, but not 21 yet. We were all drinking in their apartment. Someone called the cops because of the noise. Luckily the cops were pretty cool and just gave us all warnings, but I got to wondering...would I have been contributing to the delinquency of a minor (they are technically adults) or face any other charges from this incident? I'm in Nevada. Thanks for any answers. I want to be very careful of this situation again.
