Question: how much 40 percent alcohol to get drunk?
Answer: However if he shares it with you, you could probably drink about a shot (1.5 fluid ounces) per hour without getting really drunk. If you drink the 40% (80 proof) faster than that, it could happen very fast. About 4 or 5 shots (drink) in an hour would probably get a 15 year old (not familiar with drinking) very drunk.
