It's great going to a frat party, smoking outside with my cardboard-filtered marijuana cigarette. It's funny to see all the naive people saying "Where is the weed coming from?" When I'm just chilling there with other cigarette (tobacco though) smokers and no one is the wiser. I've even had people ask me who was smoking weed, while I was smoking my filtered joint! I just tell them there was a guy smoking around the corner or something. Plus, it's great for functionality, you can lip it, shit doesn't get in your mouth, and it doesn't burn your fingers or mouth near the roach.
