What does "Glass" mean?
Definition: Glass is the material most commonly used when smoking marijuana out of a pipe. Glass pipes can vary in color and size and can be decorated with unique designs and patterns. Glass pipes can cost quite a lot of money and sometimes break easily, but are considered much more desirable than metal pipes, which can get uncomfortably hot and give extremely harsh hits, or wooden pipes, which will not last as long and can get permanently stained with an unpleasant flavor.
