How long will nicotine extract keep its potency?

Nicotine extract can maintain its potency for about 1 to 2 years when stored properly in a cool, dark place and in an airtight container. Factors such as exposure to light, air, and heat can degrade its quality more quickly. For the best results, always check for any changes in color or odor before use. Proper storage conditions are crucial for prolonging its shelf life.
