An old way of saying you smoked a cigarette. It was like inhaling glass because the filters were made of fiberglass.

My grandpa used to eat glass every day. He was a real old-school smoker.

They called it eating glass because the filters were made of fiberglass.

Smoking was like eating glass. It was gross and confusing.
