It can lose its potency over time, yes. It takes a long time, though. If it's not wrapped up properly, it can start to deteriorate in a few months, but if it's wrapped up properly (like, in a sealed plastic bag inside a jam jar with the lid screwed on tight) it won't start losing its potency for at least a year (I think). If you have some that you don't plan on smoking for a long time, seal it up in a Ziploc bag, put the bag in a jam jar, and put the jar in the freezer.
