I would go out and purchase new pellets. There is no telling how much moisture the pellets you received with the smoker have been exposed to and could cause problems such as an auger jam or maintaining target temperature.

Taste one... if it's Hickory, you'll spit it out, if it's Mesquite, you'll try another one, if they're Cherry, there will be a 'pit', and if they're Apple, you'll feel the urge to bake a pie in your smoker!!
