I dont think decarbing is even close to the result you want in cobbing.decarbing isn't the "aim" of the sweating process at all?
I have never believed in decarbing myself there is a lot of stuff taken as fact by the cannabis community that I find hard to understand.
All you need is pot that has the effects your after, cob curing just amplifies those effects and makes it smoother to smoke.
All the things @Taima-da mentioned above have some effect on what you feel when chewing cob.
I dont understand the science behind it and dont care to know. But I know heavy smoking tolerance has a lot to do with it from first hand experience and that of heavy smokers I know.
The most critical is good pot well cured.
Just having a go at making a cob or two and then having a go at chewing it is so far from a good cure it has fail all over it.
You need commitment and talent both in growing and curing before you get results.
Although you can still smoke a badly cured cob you cannot get results from chewing it instantly.
It is worth persevering though. The chewed effects are a new experience and very different to smoking.
If you post pics of your buds and your cobs during the process experienced member here can guide you.
If your truly interested in this new experience we can def help you.
