Ok so here is the deal. You smoke a good 5-10 blunts. You take the roaches of those blunts and roll them into another blunt. There you have a generation blunt. Then you save the roaches of 5-10 generation blunts and you have another generation blunt. If you keep the rotation going you could smoke the same weed in ten years. Even with your grandkids. If I wasn't so high right now I'd do the math.
