A synthetic opiod that is both physically and psychologically addictive. Chemically related to Codeine, oxycodone (oxycontin, percodan, percocet) and Heroin. Found in prescription pain medications like
Lortab and Vicodin, usually mixed with
APAP which is toxic to your liver in high doses (if you are going to take Vicodin for fun, do a
coldwater extraction on the pills to get the APAP out).
