getting the most out of weed

[Coelho]

Never heard of that whats the goal of it to concentrate the thc or somethin?

the weed, specially when its fresh, recently harvested, have great amounts of THCA (tetrahydrocannabinoic acid), which is inactive. with the passing of time, or by the process of curing, it slowly releases CO2, turning into THC. the decarboxylation we do is just to acelerate this process, heating the weed at a suitable temperature, to help this reaction to occur fast, and thus increase (sometimes dramatically) the amount of THC in the weed.

There are more details about it in this thread:
