Human Development and Drug Addiction
Substance and drug abuse have inherent effects on human growth and development. This is more pronounced when users are addicted to some drugs like marijuana, cocaine, and alcohol, among other drugs. This study shows that various developmental aspects of a human being like the brain are affected by drug abuse. The physiological/biological, psychological, and social development is significantly affected by drug abuse and misuse as the study shows.
Drug profile overview and clinical applications
Drug addiction is a human issue that breeds physiological and psychological consequences. Drug addiction is marked by physical dependence, and is defined by the uncontrollable, compulsive urge to use a drug despite harmful consequences. Psychological responses to drug use may reflect anxiety, protective, and/or positive pleasure motivations. Physiologically, drug use affects the following areas of the brain: the brain stem, the cerebral cortex, and the limbic system. Of these, the limbic system perpetuates addiction as it reinforces the pleasure response associated with the release of dopamine that is subsequent to drug use. Five categories of drugs are discussed: stimulants, depressants, narcotics, hallucinogens, and cannabis. Prescription drugs are also considered for their addictive potential.
