there will be no problem with your friend coming, provided that he leaves the illegal substances elsewhere.
i can't think of any reason why a staff member would take a picture. that is not our policy.
just for the record: the club has property and staff in the area surrounding the club pretty much all the time. if you are caught doing something illegal there, you will not be allowed inside. if you show up at the front door obviously under the influence, you will not be allowed inside.
there are also police officers (both on duty and off) in the area pretty much all the time. what they do if they find you breaking the law is outside of our control.
when drugs are legal, i'm sure we'll sell them to you. until then, the use of illegal substances puts our license at risk. please just leave it at home.
