@MetallicArcher,

The law of diminishing returns. Drink heavily long enough and your body gains the ability to handle and dismiss the toxic effects more and more quickly. Qrow has probably long perfected his ability to appear more intoxicated than he actually is.

Also, consider how much energy Huntsmen probably burn when using their Aura attribute boosts, their bodies probably eat through sugars like no-one's business. His little slap-fight with Winter probably purged his system of booze pretty effectively.
