Drugs, Brains, and Behavior: The Science of Addiction

Individuals continue taking drugs to support the intense feel-good emotions the brain releases; this creates a cycle of drug use and intense highs. One way the brain compensates is to reduce the number of dopamine receptors at the synapse. In addition, sending neurons increase their number of dopamine transporters, more quickly clearing dopamine from the synapse. These changes make the brain less responsive to the drug, but they also decrease the brain’s response to natural rewards.

Depending on the drug taken, the effects can be prolonged for hours at a time. Even though you vomited, your brain is going to remember the euphoria you felt. As a result, your brain will “encourage” you to seek out this feeling again in the future.

Impact of Substances on the Brain

Secondly, the brain will start to numb the receptors in the brain that can interpret “pleasure” signals. EEGs are typically used to help individuals who have suffered traumatic brain injuries and can be helpful to individuals with obsessive compulsive disorder and other brain disorders. This therapy can also include meditation, guided imagery, and muscle relaxation.

Drinking also gives people bad breath, and no one enjoys a hangover. People who drink regularly also often have problems with school. Drinking can damage a student’s ability to study well and get decent grades, as well as affect sports performance (the coordination thing). If someone drinks large amounts of alcohol in a short period of time, they’re at risk for alcohol poisoning. Alcohol poisoning is exactly what it sounds like — the body has become poisoned by large amounts of alcohol. Violent vomiting is usually the first symptom of alcohol poisoning.

Slurred speech and physical imbalance are also attributed to the diminished use and inefficiency of the cerebellum and cerebral cortex which occurs due to alcohol use.

All drugs, including meth, cocaine, prescription painkillers, and everything in between, cause chemicals to be released in abnormal patterns in the brain. The effects of drugs on the brain are both immediate and long-lasting, especially with continued substance abuse. As a result of these adaptations, dopamine has less impact on the brain’s reward center. People who develop an addiction typically find that, in time, the desired substance no longer gives them as much pleasure. They have to take more of it to obtain the same dopamine “high” because their brains have adapted—an effect known as tolerance.

Dopamine Levels Increase

Different strategies for turning down alcohol work for different people. Some people find it helps to say no without giving an explanation, others think offering their reasons works better (“I’m not into drinking,” “I have a game tomorrow,” or “my uncle died from drinking,” for example). Teens who drink are more likely https://ecosoberhouse.com/article/essential-tremor-alcohol/ to be sexually active and to have unsafe, unprotected sex, which can lead to unplanned pregnancies and sexually transmitted diseases. The risk of injuring yourself, maybe even fatally, is higher when you’re under the influence too. One half of all drowning deaths among teen guys are related to alcohol use.

If someone uses Cocaine, for example, they will notice a feeling of euphoria. This occurs because Cocaine is Psychoactive and impacts the area of the brain that controls pleasure and motivation. There is a short and powerful burst alcohol vs drugs of dopamine, the chemical that causes many to feel euphoric. This feeling can be so intense that a strong desire to continue using may form. When someone develops an addiction, the brain craves the reward of the substance.
