Drugs can alter the way people think, feel, and behave by disrupting neurotransmission, the process of communication between neurons (nerve cells) in the brain. Many scientific studies conducted over decades have established that drug dependence and addiction are features of an organic brain disorder caused by drugsā cumulative impacts on neurotransmission. Scientists continue to build on this essential understanding with experiments to further elucidate the physiological factors that make a person prone to using drugs, as well as the full dimensions and progression of the disorder.
This infographic is to assist special populations, providers and organizations in explaining specific neurotransmitters, their affects, and specific drugs that affect them.
