Short answer
Most cannabis edibles keep 6 to 12 months in a freezer set to 0°F (-18°C) or colder. Cold slows the loss of THC and CBD. It does not stop the loss. Baked goods hold 4 to 6 months. Gummies and chocolate hold 6 to 12 months.

What the freezer does
Two things degrade an edible: heat and oxygen. A freezer at 0°F cuts both. THC still oxidizes into CBN, a cannabinoid with weaker CB1 activity. Terpenes fade. Fat goes rancid. Moisture is the larger risk. Loose wrap lets ice crystals form on the surface of brownies and gummies. The crystals pull cannabinoids and sugar out of the matrix. The result is a dry, uneven product.
Storage times by type
- Baked goods, brownies, cookies, cake: 4 to 6 months. Fat and texture fail before potency does.
- Gummies and chews: 6 to 12 months. Pectin and gelatin hold shape. Sugar can crystallize.
- Chocolate: 6 to 12 months. Bloom shows as a gray or white film. Bloom is cosmetic, not mold.
- Cannabutter and infused oil: 6 to 9 months. Rancid fat is the limit.
- Alcohol tinctures: 12 months or more. Alcohol limits microbial growth.
How much potency drops
Loss depends on the recipe, the fat content, and the seal. Commercial labels list a best-by date. That date assumes room temperature storage. A freezer extends it by months, not years. Published tests on stored cannabis oil report measurable loss of THC over 12 months at cold temperatures. Treat any edible past 12 months as unknown strength. Start with half a normal dose. Effects from CBN lean toward sedation and body heaviness.

Signs to throw it out
- Mold: fuzzy green, blue, or black patches. Mold appears after thaw cycles, not at a steady 0°F.
- Rancid smell: crayon, paint, or stale nuts.
- Freezer burn: gray, dry, leathery patches.
- No date or dose on the package.
Freezer method
- Cut baked goods into single doses before freezing. Refreezing thawed items speeds spoilage.
- Wrap in plastic, then foil, then a freezer bag. Press out air.
- Write the date, dose, and product name on the bag.
- Store in a locked box away from food. Keep it away from children and pets.
- Thaw overnight in the refrigerator. Wait until the item reaches room temperature before opening the wrap. This keeps condensation off the surface.
Room temperature, for comparison
Baked edibles last 1 to 2 weeks at 68°F to 77°F in a sealed container. Gummies last 6 to 12 months. Chocolate lasts 6 to 12 months. Heat above 80°F shortens these windows.

THC and CBD labels
State rules require THC content on the label. CBD labeling rules vary by state. A frozen CBD gummy and a frozen THC gummy degrade in the same way. Store both the same way.
