Prohibition Sg style? It will never work
It's got to be done gradually.
1st raise taxes on alcohol.
Limit it to home consumption.
Heavy penalties for transgressions.
Public education on downsides of alcohol with very negative stories.
Or
Go the other way.
Since alcohol is legal, make drugs legal.
Mandatory requirement that if you want to take alcohol, you gotta also take some drugs, like mRNA.
Gradual inclusion of more drugs+alcohol allowed.
No penalties for drink driving.
Drunk culture to be promoted.
Have dad-of-the-year competition to find the most drunk and deadbeat dads.
