Yea, I always suspected that the first hit must be the more potent one, but then again, as Marevix pointed out in his post, the stuff on the bottom gets resinated, so subsequent hits may be just as strong or stronger than the first. That makes total sense, which is why the question was asked.

And, yes, once you ash most of the bug in the bowl, you get that particular taste that slipknotpsycho was talking about. It's indeed disgusting, but then again, if you don't use all the weed in the bowl, you may risk wasting some at the bottom.

I know a few friends that will pack the bowl several times (at least 2 or 3) during a session of "average" size, depending on how many they are sharing with, etc. To be efficient with dank weed is important, especially if you are paying a premium. Here were I live, I get some medical grade stuff, purps, widow, and other strains which contain +25% THC. It's pricey shit, but well worth it.
