if i were you, I'd take the filter from a cigarrette, remove the spongey inside so you only have that traditional "orange" (may be different for you) tip. Roll a joint in a cylidrical shape, put some tobbaco at the very end so you can cover that part with the orange strip. .... do you follow?, if only i oculd show you
just buy the empty ciggeretes and use a ciggerete rolling machine to pack weed instead of tobacco... Rafaela your idea wont work, because even the best roller cant roll a joint in a normal rolling paper to be as tight and even as a but.
done this tons man. roll the cig between your thumb and forefinger to empty out all the tobacco and then pack it tightly with herb. use tweezers to remove the "spongey" filter from inside the end of the cig. Take something to make a tab with(like a business card) and roll it to where air can pass through. stick that into the end so it will act as a new filter.
that shit works that what i smoke and ive used the machine with bud instead of backy, also put tabacco at the end of it so it looks just like a cigarette
only problem with emptying cigarettes is that the chemicals in the tobaccoo of the cigs gets onto the cigarette paper as well
