The act of burning cannabis to consume it, producing smoke that is inhaled, as in joints, blunts, pipes, or bongs.
Combustion is the process of burning cannabis to produce smoke for inhalation. It is the oldest and most widespread method of cannabis consumption, used in joints, blunts, pipes, bongs, and other smoking devices. Combustion occurs at temperatures above approximately 450 degrees Fahrenheit (232 degrees Celsius).
How It Works
When flame is applied to cannabis flower, the plant material ignites and undergoes combustion, rapidly converting solid matter into smoke, ash, and gases. This smoke contains vaporized cannabinoids and terpenes alongside combustion byproducts including tar, carbon monoxide, polycyclic aromatic hydrocarbons, and fine particulate matter. The cannabinoids are absorbed through the lungs into the bloodstream within seconds, producing rapid onset of effects.
Combustion vs. Vaporization
Combustion is less efficient than vaporization because the high temperatures destroy a significant portion of the cannabinoids and terpenes before they can be inhaled. Research suggests that combustion converts only about 25% of available THC into inhalable form, compared to 45% or more with quality vaporizers. The smoke produced also contains harmful compounds that are absent from vapor. Despite these drawbacks, combustion remains popular due to its simplicity, accessibility, and the ritualistic satisfaction many consumers find in the smoking experience.
