A High Times reader asked why his cones burn evenly and his straight joints canoe. Josh Kesselman has a theory involving the Venturi effect, a whiteboard and a lot of arrows. The real answer involves airflow, packing density and the fact that cones forgive what cylinders punish.
“Please tell me why cones usually burn pretty straight and good but standard cylindrical doobies often burn uneven?”
That came in over email this week from a reader, Joe Pipe. It’s a good question and a more interesting one than it looks. The short answer is that a cone’s shape does real work that a straight joint asks the roller to do manually. The long answer involves Josh Kesselman, a whiteboard full of arrows and the limits of what we can honestly call science.
Josh has a theory
The founder of RAW and Publisher of High Times recently posted a video walking through why cones outperform straight rolls. He drew two joints on a whiteboard. One tapered. One straight. Same weight on both.

His pitch: a straight tube lets air pass through too quickly, which dilutes the draw. A cone narrows the flow, slows it down and concentrates what reaches the smoker. He invoked the Venturi effect, drew arrows showing rotational airflow, and landed on a number: “Cones = 18% more yield.”
An asterisk on the slide reads, in his own words: “Guestimated according to ChatGPT and my own personal experience.”
Josh built the disclaimer in. We’re going to respect it.

What’s actually happening in there
A joint is a small piece of combustion engineering. Air gets pulled through a column of shredded plant material wrapped in permeable …
