                                                          Jonesing is thought to come from "Harry Jones" which is a slang term for the drug heroin. Heroin is highly addictive, and therefore if someone is "jonesing" for something, they are craving it as one would crave a drug. However, "jonesing" does is not limited to craving drugs. One can be "jonesing" for candy, or food, or anything.
