Benefits of Vaporizing with Butane

 

The hydrogen from the burned butane created water. This water is now in the form of a little extra humidity. Humidity increases heat transfer, exactly why a damp cold feels colder than a dry cold. It works the same for heat i.e. steaming food. This superheated steam can vaporize better than drier air.

Humidity also discourages burning (oxidation). This will improve the quality of your actives. CBN the non-psychoactive cannabinoid is produced by the oxidation of THC, this will preserve THC levels. Cannabinol

Since some of the oxygen in the air was used to burn the butane there is less oxygen to oxidize the THC.
