What is Drug Addiction?
Whether prescription, over-the-counter, or illicit, mood-altering substances can be physically and psychologically addictive, changing the brain’s chemistry and reward pathways.
No one starts using drugs intending to develop an addiction. People often justify experimentation as a way to relieve pain, have fun, or cope with stress. Over time, however, continued use can lead to physical dependency and psychological cravings.
According to the National Institute on Drug Abuse (NIDA), drug addiction over-activates the brain’s reward system, making it increasingly difficult to feel pleasure or satisfaction without the substance. Prolonged drug use can damage the heart, liver, lungs, and brain, depress respiration, trigger seizures, and in severe cases, cause cardiac arrest.
