    decarboxylation question

    how long did you heat it and at what temp
    darkside Reviewed by darkside on . decarboxylation question i was just wondering if decarboxylating (sp?) pot will have any extra effects when smoked? they say to do it to increase the thc for extacts, but does the thc get dcarbolated when it is smoked or does it happen over time? im think about doing it to a couple buds when i pick up tomorro, and wanted to know if it was worth it..

    you can weaken a polar carboxyl (hydrogen, for that matter) bond with ethers or alcohols, but you'd obviously ruin your marijuana. not to mention, it has to be done in the vapor phase (i think).

    stick with putting it in your pipe and smoking it.
    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.

    more detailed references of the cannabinoids chemistry can be found in:

    decarboxylation question

    I've tried this in the oven and it seemed to work for my schwag made it a bit dryer. I put it on 200 degrees for about 10-15 mins made it a hell of a lot dryer but I felt a noticeable change in the high making me more awake than tired. I thought putting it for a lesser amount of time like 5-10 mins in a pan broken up a gram or 2 and spread out but not too spread apart the point is to heat evenly.

    There are other ways which may be better though, I found these 2 links and 2 facts.


    Heating dried marijuana makes the carboxyl group convert into water (H2O) and carbon dioxide (CO2). When marijuana is smoked, the burning eliminates the carboxyl group. There are several ways to decarboxylate marijuana for use in extracts. A layer of marijuana buds or leaf can be placed in an oven at 150 degrees for 15 minutes. This is far below the boiling point of THC yet warm enough to evaporate the carboxyl group. Another method of releasing the COOH is by placing a bowl of buds in the microwave for 2 minutes. The waves will boil away the water. The boiling point of marijuana's active cannabinoids ranges from 260-392 degrees F.

    Decarboxylation

    and

    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.

    decarboxylation question

    thats a crazy idea... and it amkes complete sense as to why it would work... i think i might try this next time i pick up. Is it worth it to do it with headdies tho? It usually is cured prety well regardless

    decarboxylation question

    Ok, so putting bud in the microwave for like 2 minutes makes it more potent?

    decarboxylation question

    It will increase the amount of THC... if the weed were indica, it will become somewhat sativa-like (as the effects of indica ones are caused mainly by CBD, which is partially transformed to THC), more mental, and less couchlock, and if the weed were sativa, it will become stronger. If the weed were already cured or dry, the increase of potency can be low (as all the THCA already was transformed to THC).
    Anyway, its always worth the try, cause the increase sometimes is great :stoned:
