You got that right. Alcohol is a straight up dirty drug that’s only around because it was simple to make and a part of Roman culture.
But getting a recreational drug « approved » for sale is difficult. But maybe not impossible.
And chances are the attributes that make it relatively safe in 500mL-beer-equivalents probably make it possible to consume 10x amounts for 10x pleasure but still 5x worse negative effects than that 500mL beer.
Alcohol’s side effects contribute to its self-limiting self-administration for a good chunk of the population.
