i've done it both ways. i certainly got high when i smoked it with the filter. but it's definately much better without.

try pullin out the little tab on the interior front side of the top of the cig pack. rip it in half and roll it up. take out the filter on the cig and put that little roll of cardboard in it's place. the roll will expand, holding open the end of the cig. worked for me. happy tokin :stoned:
