I used to put a roach in the end...
But i just got tired of it and got good enough at rolling that it wasnt even an issue, i roll perfect mouthpieces and stuff so nothing comes out, its a skill you know.
Trick is to rolling is the actual rolling part... noot like blunts i keep the paper folded but not folded over and roll the bud in between my fingers for like 10 seconds
give it a good shape, and make it tight. perfect spread tight tho so it hits.
