Storing cannabis properly plays a big part in its quality and potency. 
The elements that affect cannabis include temperature, humidity, and exposure to air and light.
The best way preserve weed is to store it in an air-tight glass jar in a cool, dark place.

Whether you're a habitual or occasional smoker, knowing how to store weed properly is arguably just as important as knowing your preferred strains or consumption methods. 

For cannabis flower in particular, it's essential to remember that what you're consuming is a plant — one that's grown, dried, harvested, and cured before it's smokable. 

Not storing anything properly that is intended for consumption will have a negative effect on the quality of the product .This can impact potency, taste, and the overall desired effects.

There are many specialized storage containers on the market, but you don't need anything fancy to store your stash properly. 

Glass is widely considered the best material for weed storage over plastic or metal.Metal can affect the taste and aroma of your flower, and that plastic creates a static charge that causes the plant to break apart and lose its trichomes, or the crystal-like tips of the flower that contain a high concentration of cannabinoids and terpenes.  

For the best long-term results, an airtight glass container is your best bet — you can even go the extra mile and opt for a UV-proof glass container. But for most people, mason jars will do the trick — you'll just want to store the jar out direct sunlight in a cool, dry place. 

Besides that, make sure your stash fits snugly inside the container. Packing the jar as tightly as possible will leave little space for oxygen to get trapped inside, which can affect the quality and humidity. 

For joints, blunts, or any other kind of pre-rolls, your storage considerations are much the same as for unground nugs. Recommends keeping them in a cool, dark area, and once you open a pack, you should consume the contents within 30 days so that they don't dry out. 

You can even use the container you brought them home from the dispensary in, since the flower is already ground, you don't have to worry about it breaking apart. But if you'd like your pre-rolls to last longer, stick them in their own appropriately-sized mason jar and pack them as close together as you can to prevent airflow.
