How long can marijuana edibles be stored? Will they lose potency over time? How about if you freeze them?
Edibles do not lose potency, so you can store them for however long the food itself is good. The same goes for freezing cannabis edibles. You can store for longer periods with no loss of potency.
Whenever possible I include freezing instructions with the recipes on this website and in my cookbooks. Prior to my cannabis career, I wrote The Complete Idiot’s Guide to Easy Freezer Meals. Knowledge of how to successfully freeze foods is handy for cannabis cooks, as you probably will not want to, nor should you, chow down on a big batch of edibles all at once.
Freezing can make portion and dosage control easier and it lets you keep edibles on hand for whenever you need them. Not all foods are suitable for freezing, but many are. A good freezer cookbook (like mine, wink, wink) can teach you those basics.
Know that you can also freeze your cannabis-infused butter and oil for longer storage. Try to use within 6 months as fats can still go rancid in the freezer, but freezing will extend their usable shelf life. I like to freeze small portions in ice cube trays, then pop the cubes into a plastic freezer storage bag. When you want to cook with cannabis, take out the amount you need and proceed.
