The brain is a complex series of neurons that communicate with one another in different parts of the brain and central nervous system. They communicate by sending neurotransmitters back and forth. A neurotransmitter is a chemical impulse that sends a specific message, but they can be altered by the introduction of other chemical substances.
How Drugs Affect the Brain
There are some drugs, such as marijuana, that artificially activate certain neurons in the brain, causing false messages to be sent. Since this is an artificial activation of the neuron, the message that neuron sends to other neurons in the brain or central nervous system will be different. This can also cause the neuron to send out large amounts of a neurotransmitter. This is a common issue with the use of cocaine or amphetamines. As a result, the responses from the receiving neurons will be exaggerated or maximized.
Which Parts of the Brain Suffer From Drug Use?
The basal ganglia, extended amygdala, and prefrontal cortex are the parts of the brain that are most commonly affected by drug use. These areas of the brain control pleasurable feelings, emotional health problems, and problem solving skills. Prolonged use can negatively affect these areas of the brain by normalizing the presence of the chemicals in the drug. Over time, an individual will need more of the drug just to feel “normal” in their daily lives.
Why Are Drugs So Addicting?
The process of addiction starts with the euphoric sensation that the drug creates in the brain. As the drug attaches to neurons, it promotes the transmission of endorphins, which are commonly known as the “feel good” neurotransmitters. That’s because the endorphins are responsible for creating the euphoric sensation in the basal ganglia. As the brain becomes accustomed to the presence of the endorphins through more frequent use of the drug, it will crave more to achieve that same euphoric sensation. This is why you need to use a drug more frequently and in larger quantities to achieve that same feeling.
If you socially drink or use drugs recreationally, it’s important to pay close attention to your use patterns. If you notice that using a particular substance doesn’t affect you in the same way, this is an early sign that you’re developing an addiction. A treatment facility can help you stay clean before the addiction worsens.
