Subtypes of codeine cough syrup abusers.

This paper highlights the abuse potential of the codeine containing cough syrups, which may take two forms. One, experimental abuse in school or college students which later persists in a dependent pattern. Two, pre-existing opioid abusers, as a substitute which starts after the school or college years. The short term treatment outcome is better in the former group in that they are able to maintain abstinence for a relatively longer period.
