Demand creates supply.
Prohibition was wrong , not only because it was unconstitutional at first lol, but more because removing supply does little to stifle demand, which creates the opportunity for being supplied a la bootleggers.
The 'War on Drugs' is obviously just as ineffectual in curbing the rate of 'illicit drug' use.
Alcohol advertisements and marketers don't try to induce alcohol consumption in general , just in particular i.e. Their brand, responsibly of course
The makers of Dewars,just as example, would rather you not consume alcohol if you do not purchase their product. That would mean no market share for their competitors and lesser costs in their supply chain.
Alcohol and other intoxicants aren't the enemy, just the Thing that wants them and that enemy can be stopped in Its tracks even while sitting in a castle make of cocaine bricks and surrounded by a moat of bourbon.
