DOES CANNABIS EXPIRE?

DOES CANNABIS EXPIRE?

I know that some of our weed enthusiasts have asked whether cannabis has an expiry date. And, if it does expire, for how long can it last? The truth is that marijuana does go bad. Cannabis is a plant, and just like other plants, it is governed by the laws of nature. All living things die and decompose to feed other organisms and create room for a new life. 

Cannabis that is carefully and safely stored can last for between 12 and 18 months without losing its potency. Marijuana is best stored in mason jars because they are airtight. To prove that cannabis has an expiry date, an example is its sale in Canada. Health Canada has made it mandatory for all legal cannabis product labels to include the necessary information for an informed decision before use. Well, that information consists of the expiry date, even though it’s always labeled, "no expiry date has been determined." 

There are a lot of factors that determine the lifespan of dried cannabis flowers, one of them being its storage, as I mentioned earlier. Some of the factors to consider for proper storage include the container quality as well as exposure to light. Cannabis lasts longer when stored in glass containers as compared to plastic or paper-based bags. Furthermore, the glass containers come with lids. The containers should be kept in the dark closet, drawer, pantry, or top cupboard cabinet. This storage method reduces exposure to light, which can speed up the degradation of THC and terpenes.

Avoid storing cannabis in the fridge or freezer because you will compromise quality. Experts are of the view that since the temperature and humidity in refrigerators fluctuates, it may affect the cannabis quality. Additionally, refrigerating cannabis increases the chances of terpene and cannabinoid-rich trichomes breaking off from the buds.

As a cannabis user, you will know when the quality is degrading when your stash loses its smell, meaning that terpenes will be fading. Again, if your cannabis develops a new scent, like musty or mildew, it may mean that it’s growing mold. Always inspect your cannabis before consumption.

To clarify, it’s not only dried cannabis flowers that expire but even oils.  

Factors that Influence Cannabis Freshness

1. Humidity

Humidity enables the growth of mold spores, which can be poisonous when smoked. Extreme temperature differences can also cause air to release moisture, promoting the growth of mold. Due to this, you need to control humidity and avoid fluctuations in temperature.

2. Light

Sunlight is detrimental to marijuana. Cannabinoids oxidize and break down from the heat. 

3. Temperature

High temperatures break down cannabinoids, turning your THC to CBN. It would be best if you stored your bud at an average temperature of 25°C. again, if the temperatures are too cold, mold growth is also encouraged. Freezing temperatures will break off your trichomes and damage the chemical composition of cannabinoids.

4. Air

Air is essential for weed curation, but after that, too much air isn’t necessary. Oxygen steals electrons from matter, causing degradation such as rust or dry rot. Oxygen will also dry out oils that carry weed's cannabinoids, making them less potent and taste harsh. You need a small amount of dry oxygen with sealed weed containers, or no oxygen at all by using a vacuum-sealed container. 

There are ways by which you can keep your weed fresh for longer. Weed expires, but you can keep yours longer by following the tips below:

? Make sure that your weed is completely cured. In case your cannabis is wet or fresh, hang it upside down for about three days. After that, store it in a sealed container and be opening the lid every two days to release the humid air.

? Invest in a relative humidity monitor. The recommended relative humidity for cured cannabis ranges between 59% and 63%. You can maintain this by using desiccant products or investing in a particular humidor-type container.

? Store your weed in a sealed container.

? Avoid using plastic or cedar.

? Store cannabis in a cool and dark place.

Cannabis concentrates and hemp seed products.

Concentrates such as CBD oil are less organic as compared to plants; therefore, they hinder oxygen from touching everything but the surface. These characteristics make much less vulnerable to factors such as oxygen and humidity. However, this doesn’t mean that they are not vulnerable. The simplest way of knowing whether your CBD oil has gone bad is through the smell and taste. It may not come to that since its visual appearance alone will tell it all. 

Expired CBD oil appears murky and cloudy. Some people prefer storing their oil in refrigerators. I’m not saying its wrong, but it can lead to the thickening of the oil. When this happens, dip the bottle in hot water. Every bottle of CBD oil will also always have an expiry date. It would be best if you looked at it before consumption. 

Know that a low-quality product is not only dangerous but also unreliable in terms of longevity. CBD oil, for sure, can last for between one and two years. Hemp quickly absorbs heavy metals and toxins from the soil. Consequently, a hemp plant in low-quality soil will produce low-quality CBD oil. On the other hand, hemp in high-quality soil will give birth to a better product. This is referred to as hyperaccumulator.

Purity is also essential in determining how long CBD oil can last. Purity doesn’t guarantee a longer shelf-life, but rather the potency.

When it comes to hemp seeds, employ the same storage practices as in weed. Whole hemp seeds are quite vulnerable because they contain oils and fats that can go rancid after prolonged exposure to heat, light, or oxygen. 

What you need to remember, though, is that weed will never go bad or expire the same way as other food products such as milk and meat do. Again, it’s not going to get less potent or get better with age like wine. The fact of the matter, however, is that cannabis has an unspoken “use-by” date.
