Alright. The roach is a different thing over here. Well, kinda. Most people use a little bit of card, rolled up, and put it in the end of the joint. Then smoke the joint upto the bit of card/roach. Saves losing out and stops any lip burning action.
Ok so you are referring to some kind of tip. Like what is on a black an mild? something like this.
I never have a problem with lip burning, I don't smoke the blunt down far enough to burn my fingers or lips, that is when it's time to put it out. There are people that smoke those things all the way down and it's crazy. It's usually the guy that doesn't throw down any weed and is just sitting in on the rotation.
I knew some people that referred to roaches as "doobies" which is odd since to most people a doobie is a joint. But to me a stick is a cigar. A roach is the leftover of a blunt or joint after you put it out.
I can split a stick very quickly with just my fingers by snapping apart the stick. If that makes any sense to you lol
