Bay Area slang for Promethazine with Codeine cough syrup. Typically available by prescription in three different sizes; 4oz, 8oz, and 12oz bottles with prices ranging from $30 for a 4oz, to 200 for a 12oz. In addition, a 16oz bottle (or "Brick" if u will) can also be obtained but it only comes available in the form of a pharmacists refill bottle and and therefore this size bottle is never prescribed for medicinal use. Typical street prices for a "Brick" range from $150 to $350.
