Decarboxylation makes marijuana more psychoactive than it is in it’s natural state. You are bringing out the most of it’s ability to give you a “high” or medicated effect when ingested. Decarboxylation happens very slowly when cannabis is curing, but we can use an oven to speed up the process. The decarboxylation process involves the conversion of THC(A) into THC (THC-A is the non-psychoactive form of THC – it produces no “high”). Decarboxylation also rapidly takes place as marijuana is being burned, or as it is evenly heated to a temperature of 222 F or higher. This comes in handy when you are going to ingest the marijuana without burning/heating/vaporizing it first.
Interesting temperature stats:
Decarboxylation: 105 C (220 F)
Boiling of Cannabinoids: 127-200 C (260-392 F)
Boiling of THC: 200 C (392 F)Flame on lighter: 1300-1977F
