Justin Bieber's skate ramp in the backyard of his home, which has a lot of graffiti might have given early warning signs about his addiction to "sizzurp".
According to TMZ.com, the graffiti has a "double cup", which is a code for lean mixed with double the amount of codeine.
It was earlier revealed that Bieber has been deep into codeine and promethazine mixed with Sprite and a Jolly Rancher, in addition to abusing Rx drugs, booze and weed.
