Morphine Addiction-
Morphine is a potentially highly addictive substance. It can cause psychological dependence and physical dependence as well as tolerance, with an addiction potential identical to that of heroin. When used illicity, very serious narcotic habit can develop in a matter of weeks, where as iatrogenic morphine addiction rates have, according to a number of studies, remained nearly constant at one case in 150 to 200 for at least two centuries.
Morphine is highly addictive. Tolerance (the need for higher and higher doses to maintain the same effect) and physical and psychological addiction to Morphine develop quickly. Withdrawal from Morphine causes nausea, tearing yawning, chills, and sweating lasting up to three days. Morphine crosses the placental barrier, and babies born to Morphine-using mothers go though Morphine withdrawal.
