I was wondering what temperature does marijuana burn at? Also does anyone know what the ideal temperature for vaporizing is?

Cannabis herb is burnt during smoking, temperatures of approx. 500-700°C being reached during this process.
Vaporization of cannabis, on the other hand, involves the herbal material being heated to a minimum of 185°C, this being the temperature from which THC (tetrahydrocannabinol - the main active ingredient in cannabis) evaporates from the herbal material and blends with air (i.e. being transformed into an inhalable form).

The Merck Index lists the boiling point of delta 1 Tetrahydrocannabinol as 200° C (392° F) 365° F appears optimal for vaporizing.

You may want to try 365/370/375 to see which temp your vap works best with.

Marijuana produces THCA, an acid with the carboxylic group (COOH) attached. In its acid form, THC is not very active. It is only when the carboxyl group is removed that THC becomes psychoactive. When marijuana is smoked, the THC behind the hot spot is vaporized as the hot air from the burn is drawn through the joint or pipe bowl to the unburned material. The liquid THC and other cannabinoids have a boiling point of between 180-200° C (355-392° F). Before they turn gaseous, at around 106° C (220° F), the carboxyl group is released from the molecule as carbon dioxide and water vapor.

I have my thermostat set at 420F degrees.

thanks ill have to set the vap at 360 and work my way up.
