Whether you stored it away intentionally or forgot about an old stash, most pot consumers have wondered whether or not their weed has gone bad at some point. The short is answer is no — but that depends on your definition of “bad,” as well as the method in which you stored it.
Technically, weed doesn’t go bad in the sense that it will have a negative effect on the user. Antique pot won’t poison you or have a dramatically different impact on your body. But its potency can certainly decrease or, at the least, be altered if not stored properly.
Marijuana plants have a number of chemical compounds known as cannabinoids present in their flowers. When these buds are dried out and subsequently heated, the cannabinoids are converted from biosynthetic acids into the weed’s psychoactive substances in a process known as decarboxylation.
Tetrahydrocannabinol (THC) starts life as an acid, called THCA. Decarboxylation, which occurs through heating and drying, transforms non-psychoactive THCA into THC.
THCA can be converted into a different cannabinoid called CBNA (and thus CBN) if the cannabis is exposed to excessive heat or sunlight. CBN is less psychoactive than THC, meaning its consumption does not get the user as high. While CBN can get you high, its effects are less euphoric and more soporific (sleepy). It also doesn’t last as long.
How to Store Your Cannabis For Maximum Shelf Life
When cannabis is first harvested, it must be dried and cured. This process is important for a few reasons: it helps break down chlorophyll resulting in a much more pleasant flavor and odor, it improves the cannabinoid profile which makes it more potent, it reduces the chances of a harsh or rough inhale and the likelihood of mold growth during storage.
When you purchase your marijuana from a dispensary, the bulk of the curing process will be done for you; all you have to do is store it properly. If you’re growing your own, however, you will need to dry and cure your harvest thoroughly before it can be stored. You will do this by drying trimmed buds upside-down or on a wire rack for around two weeks (or until the thickest stem snaps) then adding them to an air-tight container. Store containers in a cool, dark location and “burp” or open the lid once every day or so. Once the buds have been fully-cured, you’re ready to move on to your next step.
Prepare your stash for the long-haul by storing it in an air-tight container in a cool, dark location (the same place used for your initial curing phase will be perfect). At this point, you can continue the curing process for about six months by burping your jar (allowing air in) every month or so.
If you plan on storing your cannabis longer than six months, vacuum sealing the product might be the best option if you want to maintain the same cannabinoid profile (provided that it is completely dry). If you need to add moisture to the buds, you can do so using a Humidipak, but not before long-term storage.
For the best (and safest) results, you should store your cannabis in a secure location well away from children. Though there are many options for cannabis storage, we recommend using STASHLOGIX stash boxes. These customizable cannabis storage containers are discreet, secure and portable. They also feature an odor-absorbing liner to help keep the aroma at bay. Whether storing your marijuana long-term or just until your next session, StashLogix can help you keep your weed both secure and organized.
