How much does a ghost hit smell?

I'm amazed you haven't tried a ghost hit just to answer that question. I'd say ghost hits do release the smell of smoldering cannabis into the air, the strength of the odor depends on how much smoke was in the hit and how distinctive the smoke from that particular bud smelled. Other factors include distance to the smeller's nose, air speed and direction, and the level of sophistication of the smeller regarding pot smoke. We could probably come up with a formula but since we don't have a number for sophistication that part would need to be estimated. In other words there is no definitive answer to your question
