A:Vaporizers work by using heating elements rather than flames. Substances are heated to the exact temperature at which the active chemicals in herbs turn into vapor.
For example herbs and tobacco will actually vaporize into a ‘thin mist’. This mist is the vapor, comprising of active chemicals which are then captured in a small glass dome ready to be inhaled via the tube whenever you want to.
