What is the difference between heroin, codeine and morphine?

Chemically, nothing. All three of these drugs are derived from opium or the opium chemical structure and are in the Opiate class of drugs. The difference is primarily in the manner in which opium is refined or synthetically manufactured and the form and method of delivery. The body also changes codeine (used in some cold medicines) to morphine. Thus, the presence of morphine in the urine indicates heroin, morphine and/or codeine use.
