Document Summary
Drug: any substance other than food that affects our bodies or minds. *currently we use the term substance to include: alcohol, tobacco and caffeine. Substance intoxication: experience of significant maladaptive behavioral and psychological symptoms due to the effect of a substance on the cns. Substance withdrawal: experience of clinical significant distress in social, occupational, or other areas of functioning due to the cessation or reduction of substance use. Tolerance: with repeated use of a substance more of it is required to obtain the same effect. The first brain area affected is that which controls judgment and inhibition. Next affected are additional areas in the cns, leaving the drinker even less able to make sound judgments, speak clearly, and remember well. Motor difficulties increases as drinking continues, and reaction times slow. Fetal alcohol syndrome: this is heavy alcohol consumption during pregnancy--leading cause of mental retardation. Cranial, facial, and limb anomalies are produced. Also known as arnd (alcohol-related neurodevelopmental disorder).
