2 Chainz is blaming Justin Bieber for getting his codeine cough syrup of choice yanked off shelves -- but he's also giving the Biebs full hood status ... by accident.
The rapper joined the Drink Champs podcast with N.O.R.E and DJ EFN and openly talked about his lean habit, and bemoaned the fact his favorite brand, Actavis, is no longer for sale.
Chainz thinks JB, and a few others, are responsible for the drug's demise -- but watch what happens when he starts backing up the bus.
If this is true ... Bieber better get used to getting pulled over.
