Effects of Drug Abuse and Addiction
Drugs are chemicals. Different drugs, because of their chemical structures, can effect 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.
Depending on the drug, it can enter the human body in a number of ways, including injection, inhalation, and ingestion. The method of how it enters the body impacts on how the drug affects the person. For example: injection takes the drug directly into the blood stream, providing more immediate effects; while ingestion requires the drug to pass through the digestive system, delaying the effects.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.Know The FactsIllicit drug users make over 527,000 costly emergency room visits each year for drug related problems.One dollar out of every $14 of the nation's health care bill is spent to treat those suffering from smoking-related illnesses.Drug offenders account for more than one-third of the growth in the state prison population and more than 80 percent of the increase in the number of federal prison inmates since 1985.More than 75 percent of domestic violence victims report that their assailant had been drinking or using illicit drugs at the time of the incident.Substance abuse and addiction are fully treatable.
