Smoking - Help! Swim's pot is awful

[Mystopia2000]

Swim's pot is garbage. It's weak, tastes terrible, and is full of stems. Swim has bought an oz on three occasions from one particular supplier. The first oz was fantastic, the second was terrible, the third is even worse. Swim hasn't gotten more than slightly buzzed with this stuff yet. Tonight, Swim has spent two hours just trying to smoke enough in every possible way. He tried: bong; pipe; joint; waterfall bong; shotties. Swim got many fantastic rips and should be just floored, but the pot is just so bad. Swim doesn't mean to rant, he just wants to give a bit of background for his questions:

If none of these smoking methods worked for Swim, is there anything he can do with the pot to make it worthwhile?
Perhaps baking brownies or something? but if the pot is really weak, will that just make bad tasting ineffective brownies?
Or is there an easy and effective way to perform an extraction?

Also, does it mean anything that the pot tastes like swamp-ass? It's just not the taste Swim is use to.

Thanks!
