The shelf life of marijuana is important for many reasons. It only lasts so long, even if it is still unused in a baggie or stored properly. Some people would try to smoke or use it anyways, but there are some general guidelines to follow when thinking about the true shelf life of medical marijuana that may be helpful. Check out these tips on assessing the quality of the weed in your home and whether or not marijuana can ‘go bad.’
Why Shelf Life Matters
Under ideal conditions, cannabis can stay fresh for a long time. When harvested, dried, and stored, weed can stay fresh anywhere from six months to a year. This can stretch a little bit but flexibility depends on the type of cannabis and how well it is stored. Humidity, storage containers, and light or temperature can all impact the shelf life of cannabis. Here are some helpful hints about cannabis shelf life:
- Use it within six months of purchase
- Invest in quality storage equipment
- Speak with a budtender or dispensary before using any questionable cannabis products lying around
Can Marijuana Go Bad?
A common question to ask is whether or not marijuana can go bad.
The chemicals in marijuana break down over time. Like any product (except, maybe, Twinkies), the chemical makeup changes and makes the product less effective over time. The cannabinoids and terpenes found in cannabis lose potency. This can be dangerous for people using it medicinally, where they need full potency to fight cancer, chronic pain, or other issues. Old weed also tastes bad and won’t smell the way it used to. This can impact how a person uses or perceives the use of it. Old, worn-out bud, won’t be as potent but also can be wasted when left lying around. Be sure to use it in the right amounts rather than saving some. Fresh is always better.
Signs of Cannabis Gone Bad
Cannabis is like food. It has a certain smell and flavor when it goes bad. Here are a few things to look for when testing out whether that cannabis in the closet is still good:
- Check for mold that may have developed
- If it is dried out, or dusty, it is too old to use
- Crisp, fresh weed is going to smell brighter than old cannabis
- Cannabis is spongy and doesn’t make sounds. If it is crunchy or breaks apart, it is too old
To keep cannabis fresher longer, it helps to limit exposure to light and open air. Anywhere from 54 to 63 percent humidity is acceptable. Mason jars and containers specifically made for marijuana are always helpful. This will support a better product and keep it fresh as long as possible. Write the date of purchase on the lid or a label and maybe approximate shelf life to be aware of how long you have to use it until it goes bad.
How to Increase the Shelf Life of Weed
If you’re wondering what the best ways are to prevent cannabis from going bad and preserve that precious weed, look no further. There are some great ways to increase shelf life and maximize its usefulness.
Cut the Light
Light is a form of radiation meaning UV rays ionize and degrade organic material (like cannabis). Try to keep weeds out of direct light of any kind by using opaque storage containers and keeping them in a dark space.
Go for O2
Plants need oxygen and cannabis is no different. If oxygen levels are high, it might trash your stash. Too low and it can affect the humidity in storage which may ruin the cannabis. An airtight seal can help take care of oxygen issues.
Humidity Control
Cannabis shelf life is better with good humidity control. This keeps away mold or mildew from your stash. Too little and it can dry it out. Relative humidity should be between 59 and 63 percent for the best maintenance of consistency, color, aroma, and flavor.
Storage Material
To keep cannabis fresh, it helps to have good storage containers. Stay safe from plastic or bags that increase humidity. Glass or ceramic containers with an airtight seal are the most ideal for keeping products dry and cool. Also, make sure it is opaque and keeps the light out.
The shelf life of your weed stash can be longer and more consistent with a few tweaks. Everyone can benefit from learning how to store it properly and keep it fresher and longer. With these few simple tips and rules, it should help.
