Overdose

Closes down the respiratory center in the brain, almost paralyzing breathing and in many cases causing death

Stimulants

Substances that increase the activity of the central nervous system, resulting in increased blood pressure and heart rate, more alertness, and sped-up behavior and thinking

An addictive stimulant obtained from the coco plant and the most powerful natural stimulant known

Cocaine Intoxication

Symptoms are poor muscle coordination, grandiosity, bad judgment, anger, aggression, compulsive behavior, anxiety, and confusion

Some people have hallucinations, delusions, or both

Crashing

As the stimulant effects of cocaine subside, the user goes through a depression-like letdown, causing a pattern that may also include headaches, dizziness, and fainting

Genetic Predisposition

People may inherit a predisposition to misuse substances

Reward Circuit

A dopamine-rich circuit in the brain that produces feelings of pleasure when activated

Incentive-sensitization Theory of Addiction

As substances repeatedly stimulate this reward circuit, the circuit develops a hypersensitivity to the substances, contributing to future desires for them

Reward Deficiency Syndrome

People who chronically use drugs have a reward circuit that is not readily activated by the usual events in their lives, so they turn to drugs to stimulate the pleasure pathway, particularly in times of stress

Equifinality

The principle that different developmental pathways can lead to the same psychological disorder
