Reduced Harmful and Potentially Harmful Constituents (HPHCs)
Tobacco/botanicals and e-liquid are heated separately to maximize flavor while minimizing harmful chemical formation. In tobacco HPHC formation is a function of temperature. At temperatures approximately above 150 Deg C tobacco starts generating HPHCs. When heating other botanicals, the chosen heating temperature should maximize the formation of the desired active chemical compound(s) while minimizing or eliminating the formation of harmful chemicals.
