Gambling is a risk. Because the result of that risk is unknown and there may be a chance to win back lost wages, people gamble. The sights and sounds of the casino start to excite the person and dopamine surges. Dopamine is a “feel good” chemical released by the brain. Then the real gambling begins. When gambling the brain releases even more dopamine which causes a feeling of satisfaction and excitement. So, when dopamine is released then lessens the craving for more dopamine rises again. To obtain the release of dopamine, that person gambles even more. This is a vicious cycle that many people get caught up in. They can lose money, jobs, and family because of it. One way that is shown to help with this addiction is by taking the medication Naltrexone.
