What does “Lid” mean?
Common terminology used in the United States during the 1960s and 1970s to describe approximately an ounce of cannabis. While the origin of this term varies, many agree that it comes from the specific style of coffee cans used during the 1960s, the lids of which peeled off like sardine tins. A lid can also be equivalent to about four fingers' (measured horizontally against the container) worth of weed.
