When I was growing up both of my parents smoked cigarettes, so I was familiar with the concept. When I was about four, I was outside playing in the yard and heard my mother yelling at my older brother. She was getting after him about "smoking grass". I, of course, plucked a bunch of it out of the ground and wondered to myself "now why would anybody want to do that?"
