The 'Drug Education Agency' straight cylinder bong is a clean, simple, effective design from Black Leaf. At a crazy 20 inches tall, the tube has the 'DEA' logo on the front and will stack a massive amount of smoke before you clear it like a pro! They have given it a carb hole on the side but include a rubber plug for you to block it if you would rather just pull on the bowl to open it up for clearing. The removable downstem has an 18.8mm female ground glass joint and Black Leaf include an 18.8mm male ground glass bowl.
