Temperature is the most critical aspect to consider when you think about combustion and vaporization. Some vaporization devices heat the cannabis below the combustion point between 180-190 degrees Celsius (this is 356-374 Fahrenheit). With combustion, the lighter produces an open flame that goes beyond 315 degrees Celsius or 600 degrees Fahrenheit. The combustion process offers a very high temperature that takes off a substantial amount of cannabinoids and terpenes before the cannabis is even consumed.
