Researchers are discovering that drug addiction can be prevented. Community leaders, medical professionals, and families have developed nationwide programs to help put a stop to drug abuse. It’s important for everyone to understand the risks involved when people take drugs. It’s a serious problem in our country, and people need to be aware of it. Most people believe that the majority of people spending time in jail are addicted to drugs, alcohol, or both. It’s important for the community to know that drugs are dangerous. However, by the same token, drug addiction can be prevented as along as people don’t abuse drugs in the first place.
Through years of study, researchers are beginning to understand how drugs interfere with the brain’s communication system. The nerves in your brain are responsible for calling, sending, receiving, and analyzing information. Drugs actually interfere with the brain’s natural communication system in many ways. Interestingly, drugs imitate the brain’s messengers. For example, heroin and marijuana have the same structure as the brain’s chemical messengers, so they are capable of imitating those messengers.
The chemical messengers in your brain are referred to as neurotransmitters. Since drugs have a similar structure as the neurotransmitters, they transmit abnormal messages and fool the brain. Drugs like meth and cocaine transmit large amounts of these messages to the brain.
Drugs also stimulate the reward portion of the brain with a neurotransmitter called dopamine. Dopamine is responsible for controlling peoples actions like movement, emotion, and motivation. It also makes the brain respond favorably to behaviors like eating, sleeping, and spending time with loved ones. Heroin and marijuana over stimulate the brain’s reward and produce a feeling of joy to the user. Drug users describe it as a feeling of euphoria.
In order for drug users to re-experience a feeling of euphoria, they continue to abuse drugs. After repeated usage, the brain reduces the amount of dopamine receptors in the brain. When this happens, it becomes more difficult for the user to achieve the same high as before, which is the reason why people take larger quantities of drugs.
