Coffee is a stimulant and can make people feel alert. It can thus mask the level of intoxication the person has. The Centre for Disease Prevention and Control warns against mixing alcohol with coffee. This is because it may give you a false sense of security, making you consume more drinks and putting you in greater danger. Caffeine does not have any effect on alcohol metabolism and will not help you get sober quickly. People who consume energy drinks with alcohol are more likely to have alcohol-attributable harms, including unsafe driving and unsafe sex. Neither does it help one pass a blood or urine test. Water can increase the rate of elimination of alcohol, but it is a myth that water chugging can help you pass a test. It does not prevent alcohol from being positive in a urine sample. If you are worried about passing a test, please consider getting professional help. Alcohol-use disorder is treatable, and early treatment ensures quick recovery.
