Smoke weed without the additional residue that would come from smoking a joint!
Glass smoking pipes might be heavier, less discrete and might be easier to break - as a glass is more fragile. but they do not heat up on the outside as metal pipes do.
Glass smoking pipes generally burn faster than joints which tend to have a slow burn thus making it easier to get high.
One can see the smoke fill as the glass is lit, which tends to change the color of the pipe - Drawback is the cleaning of the pipe. Yet, the Glass pipe cheaper than a bong while a Bong is more expensive but gives a smoother and better hit.
