One of the most addicting chemicals in our environment is alcohol. It influences our brain directly and activates a number of neurotransmitters. For instance, it inhibits the release of glutamate in the brain, which lowers energy levels and brain activity.
However, the impacts it has on dopamine are the most important. Alcohol consumption increases when dopamine levels are affected.
This is so because the neurotransmitter dopamine regulates the brain's reward and pleasure regions. Alcohol initially causes the brain's dopamine to release more, creating a sensation of pleasure or delight. But with time, it weakens and lessens the function of dopamine receptors in the brain.
After some time passes, a person reaches a point where consuming more alcohol is necessary to get the same euphoric high or joy as before.
