This was one of the biggest issues when i smoked crack everyday. Speaking of crack, I think the guy smoked it wrong. I used to used brillo and a stem or that not around a 12oz drinking can with some weed screens covered with ashes for the crack to melt a cool in the ashes with out vaporizing or it running str8 to the holes in the can and dropping inside, wasting it. I tend to use cans more because with small holes and a carb, the additional space inside the can for vapor would give huge hits, that you could share with others...second hand crack vapor yo. Well i'm off to wash my face and smoke a fresh bit of tina in a bleach,soap and iso cleaned pipe i PREPPED tUESDAY. :p NOMAD BLOODBATH
