The main drawback is that for some people, sports betting can be addictive. Like any addiction, be it food, sex, or alcohol; betting addiction can be a serious problem that costs a lot of money and is personally damaging. ******** stimulates certain receptors in the brain that trigger a pleasure response. Some people are programmed to want that chemical impulse over and over again. There is an argument that these people may have found an addiction elsewhere, no matter what, and that ******** is just a trigger.
