its a plastic hollowed out pen, with the metal part that went around the part you write with, taken out, then flipped and put back in to use as a make shift bowl. Is that metal safe? And when i light it, will the smoke passing through the plastic pipe be harmful? Thanks.
no unless you smoke for 1-2 hours strait it should be ok, better to be safe than sorry. better to get a 100% metal one
Better yet, get a glass one. Don't fuck with homemade plastic pieces, or aluminum in any capacity for that matter.
plastic melts at 212 degrees C and smoke is around 230 so unless you use it allot it should be fairly safe
