To store cannabis edibles properly, it's best to use airtight containers or freezer bags and store them in a cool, dry place. Silicone containers, glass jars, and the freezer are all popular options. Edibles with sugar, oil, or flour are best kept in the fridge. It's important to pay attention to the expiration date and to look out for signs of spoilage, such as discoloration, mould, and changes in texture or smell. If you eat expired edibles, you may experience a loss of potency or other unpleasant effects.
