i have blank cigarette tubes that i use for making my own cigarettes; can leave the filter in the cigarette and still get the same potential from the herb or do i have to take out the filter and put a roach in?
but in all seriousness, no, you should roll up a piece of cardstock in a spiral and insert it where the filter used to be so it holds its shape. no weed in the mouth either, since dropping weed down a hollow tube usually happens to do that.
i think he means does leaving the filter in take thc away. i leave it in and havent noticed a differnce. sometimes if i only have a little on me and a ciggy i take a little bit of tobacco out of the end and pack it back up with weed so just the end has it in it
