Excuse my ignorance but what are “lines” of codeine cough syrup?

I didn't know at first either. But I've heard it a couple times. It's an oz of lean. because when bought in baby bottles for example, the lines indicate an ounce. So to buy "2 lines" would mean that you get enough lean to fill up to the second line in a measuring container of sorts that marks ounces
