Investigators found drugs and drug paraphernalia all over the place while serving a search warrant last week on the pint-sized hit maker, law enforcement sources told celebrity gossip site TMZ.com on Monday. Deputies investigating Bieber's alleged egging of a neighbour's house didn't touch any of the drugs because those finds would have been beyond the scope of their search warrant. They were only on the hunt for video equipment that Bieber might have used to record the alleged egging. While looking for those cameras, deputies saw two large cookie jars filled with marijuana, four or five empty codeine bottles and three bongs - one in the TV room and two more in the kitchen, according to TMZ. Bieber's home was also strewn with styrofoam cups used to drink the puny pop star's favourite cocktail, "Sizzurp" - a combo of codeine and a sweet soft drink, the site reported. While Sprite is often the mix of choice for "Sizzurp," Bieber is reportedly fond of pineapple Fanta for that concoction.
