Morphine

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 through Morphine withdrawal.

Addictive drugs, such as Morphine activate the brain’s reward systems. The promise of reward is very intense, causing the individual to crave Morphine and to focus his or her activities around the taking of Morphine. The ability of Morphine to strongly activate brain reward mechanisms and its ability to chemically alter the normal functioning of these systems can produce a Morphine addiction. Morphine also reduces a person’s level of consciousness, harming the ability to think or be fully aware of present surroundings.

Morphine was first used medicinally as a painkiller and, erroneously, as a cure for opium addiction. Morphine quickly replaced opium as a cure-all recommended by doctors and as a recreational drug and was readily available from drugstores or through the mail. Substitution of Morphine addiction for alcohol addiction was considered beneficial by some physicians because alcohol is more destructive to the body and is more likely to trigger antisocial behavior. Morphine was used during the American Civil War as a surgical anesthetic and was sent home with many wounded soldiers for relief of pain. At the end of the war, over 400,000 people had the “army disease,” Morphine addiction. The Franco-Prussian War in Europe had a similar effect.
