Brief Summary

Heated tobacco products (HTP) are devices which heat, but not burn tobacco. They do not produce cigarette smoke but rather an aerosol. HTPs are marketed as less harmful alternatives to smoking. Use and awareness of these devices have grown exponentially in recent years, with probably millions of people currently using them. There is very little literature about them, so it is quite important to study the effects caused on the human body by these products. The benefits and risks of HTP use are uncertain. There is no research on the acute oral effects of HTPs in the scientific literature.
