There isn’t much you can do if you wind up with annoying neighbors prone to making noise complaints, but there are a few ways to avoid making the situation worse. 1) Don’t answer the door holding a marijuana pipe. 2) When an officer asks about your peculiar odor, don’t say, “Oh, that’s weed.” 3) When asked for ID, don’t invite the cops into your apartment if you have five pounds of heroin sitting on your kitchen table. Frank Giardina, 49, of Flushing, Queens learned these lessons the hard way on Friday night, and he’s now facing up to eight years in prison for first-degree criminal drug possession.
