>>3763284Alcoholism isn't a mental health issue that you can prevent. It's a biological issue with the brain's reward mechanism that gives too strong a response for stimulants such as alcohol, making the person prone to addiction. In their brains, the reward for getting drunk overrides anything else.
There are treatments for this, such as the Sinclair Method, which uses reward blocking drugs to tone down the response to alcohol - or you can recognize that you have an overstated response to alcohol and abstain from using it. Either way, the stupidity is with the person for not recognizing and admitting the problem and seeking a remedy for it - despite facing adverse consequences for it. Insanity is doing the same failing action over and over and expecting a different result.
