Like any other food product, weed gummy bears can expire over time. The shelf life of weed gummy bears depends on several factors, such as the ingredients, the packaging, the storage conditions, and the potency of the cannabis. In general, weed gummy bears can last for several months if they are stored in a cool, dark, and dry place, away from heat, light, and moisture. However, if they are exposed to high temperatures, humidity, or sunlight, they can degrade faster and lose their flavor, texture, and potency. Additionally, weed gummy bears can become contaminated with mold or bacteria if they are not sealed properly or if they come into contact with water or other substances. Therefore, it is important to check the expiration date on the package and inspect the gummy bears for any signs of spoilage before consuming them. If the gummy bears look or smell bad, have changed color or shape, or have developed a fuzzy or slimy coating, they should be discarded immediately. Consuming expired or spoiled weed gummy bears can cause adverse effects such as nausea, vomiting, diarrhea, and reduced effects of THC.
