i wasnt sure where to put this

i wasnt sure where to put this so ill put it here, when me and my bro started smoking we would empty a cigarette and fll the tube w/bud. would/does the filter remove thc or any other good stuff? any other opinions or thoughts?

whenever i did that and rolled up a cigaweed i would always take off the filter.

bump, i dunno it didnt seem to matter last night if i kept it on or off but it did seem like a waste of bud the cigarette paper made it burn alot quicker than a j imo. i was bored though lol. anyone else wanna chime in?
