describe the effects narcotics have on the brain

Answer 1

Answer 2

Drugs are made of chemicals, many similar to the chemicals already in our system. Drugs alter the way nerve cells normally send, receive, and process information. They do this by imitating the brain’s natural chemical messengers, by over-stimulating the “reward circuit” of the brain, flooding the brain with excess chemicals, and binding to receptors in the brain.

For example, some drugs, such as marijuana and heroin, have a similar structure to chemical messengers, called neurotransmitters, which are naturally produced by the brain. Because of this similarity, these drugs are able to “fool” the brain’s receptors and activate nerve cells to send abnormal messages. This results in the “high” you feel when you take these drugs.

Other drugs, such as cocaine or methamphetamine, can cause the nerve cells to release abnormally large amounts of natural neurotransmitters, or prevent the normal recycling of these brain chemicals, which is needed to shut off the signal between neurons. This disruption produces a greatly amplified message that results in a different type of “high.”

Nearly all drugs, directly or indirectly, target the brain’s reward system. The overstimulation of this system, which normally responds to natural behaviors that are linked to survival (eating, spending time with loved ones, etc.), produces euphoric effects in response to the drugs. This reaction sets in motion a pattern that compels some people to repeat the behavior or abuse more drugs.

Answer 3

typically dopamine increases in response to natural rewards such as food. when cocaine is taken, dopamine increases are exaggerated, and communication is altered

Answer 11

While the specific physical and psychological effects of drug abuse and addiction tend to vary based on the particular substance involved, the general effects of abuse or addiction to any drug can be devastating. Psychologically, intoxication with or withdrawal from a substance can cause everything from euphoria as with alcohol, Ecstasy, or inhalant intoxication, to paranoia with marijuana or steroid intoxication, to severe depression or suicidal thoughts with cocaine or amphetamine withdrawal. In terms of effects on the body, intoxication with a substance can cause physical effects that range from marked sleepiness and slowed breathing as with intoxication with heroin or sedative hypnotic drugs, to the rapid heart rate of cocaine intoxication, or the tremors to seizures of alcohol withdrawal.
