Abstract: Drugs are chemicals. Different drugs, because of their chemical structures, can affect the body in different ways. In fact, some drugs can even change a person’s body and brain in ways that last long after the person has stopped taking drugs, maybe even permanently. Most abused drugs directly or indirectly target the brain’s reward system by flooding the circuit with dopamine. Dopamine is a neurotransmitter present in regions of the brain that regulate movement, emotion, cognition, motivation, and feelings of pleasure. When drugs enter the brain, they can actually change how the brain performs its jobs. These changes are what lead to compulsive drug use, the hallmark of addiction. Although initial drug use may be voluntary, drugs have been shown to alter brain chemistry, which interferes with an individual’s ability to make decisions and can lead to compulsive craving, seeking and use. This then becomes a substance dependency. All drugs of abuse - nicotine, cocaine, marijuana, and others - affect the brains “reward†circuit, which is part of the limbic system. This flood of dopamine is what causes the “high†or euphoria associated with drug abuse.
