If you ever need a FPR screen go to any place that sells rolling papers and ask them if they have pipe screens. Or go to a smoke shop. They sell packs of 5 for about 2 dollars. They come in brass or what they call silver, probably steel. You might be better off with brass. It should be easy to trim with sissors and wont rust like steel might. And after you get that all done, pack a bowl with some good weed and go for a nice ride!!!!!!!!!!!!!

I don't know about the weed smoke, but the screen idea is good.

 

im with the duck on this one, i prefer to get high off of diesel smoke!
