How to Store Your Cannabis So It Stays Fresh

Cannabis starts losing potency the moment it is harvested, and how you store it at home has a real effect on how fast that happens. The three enemies of freshness are light, heat, and air exposure - all of which speed up the breakdown of THC into less potent CBN and cause terpenes (the compounds responsible for smell and flavor) to evaporate.

For flower, an airtight glass jar kept in a cool, dark place - a cabinet or drawer, not a sunny windowsill - is the gold standard. Avoid the refrigerator or freezer for regular storage; the humidity swings can encourage mold and damage trichomes. If you live somewhere humid, a small humidity-control pack (the same kind used for cigars) keeps flower in the ideal 58-62% relative humidity range without drying it out or letting it get too moist.

Edibles should be stored per their label - most have a shelf life similar to the food they are made from, and anything with dairy or fresh fruit should be refrigerated. Concentrates like wax and shatter are more heat-sensitive than flower and are best kept in a cool, dark spot in their original non-stick container; heat can cause them to melt together or lose consistency.

And always keep everything out of reach of children and pets, in child-resistant packaging when required by law - a rule DC, Maryland, and Virginia dispensaries all take seriously, and one worth taking just as seriously at home.
