One of the most obvious questions that comes up when you are activating cannabis to use for various products or to smoke or vape is “how long does cannabis stay fresh after decarb?” As with most marijuana inquiries, there are many different opinions on how long you can store weed after decarboxylating before THC and CBD degrade/how long cannabis will stay potent after activation, but only the science provides reliable proof.
The results below show two different strains, one THC dominant and the other CBD, both decarbed in the NOVA and then stored in a plastic bag in a cool, dark drawer for a little under six months. Check out the results and let us know in the comments if they match your hypothesis or not!
We decarbed some Sour Apple back in June, and tested a portion of it immediately after. Analysis of the remaining batch tested six months later in early January showed no significant loss of THC during the storage period. In fact, aside from a tiny amount of CBN (a degraded form of THC that can make you groggy/helps with sleep), the two samples are nearly identical with over 19% THC (190mg of THC per gram of cannabis).
Lilly Hill was our strain of choice for a CBD test. After 6 months, we found mild CBD degradation – a reduction of about 30 mg per gram – from 18.5% CBD in the fresh sample (185 CBD mg per gram) to 15.84% CBD (158 mg CBD per gram) in the 6 month post-decarb sample. Despite this bit of loss, there is still significant CBD in the decarbed cannabis that was stored for 6 months.
In summary, while we recommend consuming freshly decarbed cannabis, especially when it is so easy to decarb anytime or anywhere with NOVA, these latest results indicate fresh doesn’t necessarily mean best. If stored in a cool, dry and dark place, decarbed cannabis can have a more than adequate shelf life.
