The dark sticky substance that forms when tobacco is burned is known as tar. Tar is a byproduct of burning tobacco and is a mixture of solid particles and liquid droplets that can accumulate in the lungs and other parts of the respiratory system when tobacco smoke is inhaled. It is a major contributor to the harmful health effects of smoking, as it contains numerous toxic and carcinogenic compounds.
