And alcohol has always been highly accessible. I have 5 stores within a 5 minute walk of me that I can get it from, and that's not to mention all of the restaurants and bars within that same radius.
Addiction is addiction. Alcohol is one object of that addiction. Sports betting can be another. Porn, food, drugs, etc.
What's to say sports betting addiction won't become as severe as alcohol now that it's becoming more accessible to the public?
