A whiskey coke is typically 1:3 respectively, which ends up around 10% ABV and 0.0064% caffeine.
A oolong highball, very popular in JP and mentioned in many of those twitter replies, are typically 3:2 shochu(30% ABV):tea, which ends up around 12% ABV and 0.0088% caffeine.
Big variance on the caffeine level depending on the type of tea and source of data, with 0.004% - 0.012% between green and black teas.
1:1 of ASAP Club and Chamisul soju would be 10% ABV and 0.0104% caffeine
The infamous FourLoko was supposedly 12% ABV and 0.023% caffeine.
It's really less a problem of concentration than dose. A whiskey coke or highball is a standardized 250-350ml, but kids mixing alcohol (especially already flavored and heavily sugared soju/sake!) and energy drinks themselves tend to lead to overdrinking.
