Single question identifies most problem drinkers

Dawson D.A., Pulay A.J., Grant B.F. ‘A comparison of two single-item screeners for hazardous drinking and alcohol use disorder’. Alcoholism, Clinical and Experimental Research: 2010, 34(2), p. 364–374.

Can you get away with asking just a single question to identify risky drinkers and even dependent drinkers? When the thresholds are suitably adjusted, asking either about frequency of heavy drinking or maximum single-occasion consumption worked remarkably well in the US general population.
