Alcohol Awareness Facts: What Every Adult Should Know

In the U.S., one standard drink has about 14 grams (0.6 fluid ounces) of pure alcohol. That's roughly:

Real pours are often bigger. A tall can of strong craft beer, a big glass of wine, or a mixed drink with two shots can each be two or more standard drinks.

NIAAA defines binge drinking as drinking that brings your blood alcohol concentration (BAC) to 0.08%. For a typical adult, that's about 5 or more drinks for men or 4 or more for women in about 2 hours.

NIAAA defines heavy drinking as 5 or more drinks on any day, or 15 or more a week, for men; and 4 or more on any day, or 8 or more a week, for women. Less is better for health.

In most states, driving with a BAC of 0.08% or higher is illegal for adults 21 and over. Utah's limit is 0.05%. Drivers under 21 face much lower limits, often near zero. Your driving skills start to slip well below 0.08. The only safe plan is not to drive after drinking.

Your body clears alcohol at a fairly steady rate. Coffee, a cold shower, food after drinking, or walking it off do not lower your BAC. Coffee can make you feel more awake while you're just as impaired. NIAAA warns these "fixes" don't reverse alcohol overdose and can make things worse.

Alcohol is still being absorbed after you stop drinking. Someone can get more drunk, even pass out, after the party ends. That's why "they just need to sleep it off" can be dangerous.

Alcohol slows the part of your brain that plans, pauses and thinks about later. That's why people say and do things drunk that they never would sober. It makes it harder to:

• Read other people's intentions (a look feels like a threat).
• Stop and think before reacting.
• Walk away from a fight.

Alcohol is involved in a large share of fights, domestic incidents and impulsive crimes. If anger or bad decisions are part of your story, alcohol is worth a hard look. See anger management techniques and impulse control techniques.

A drink after a hard day feels like relief. But alcohol disrupts sleep, and poor sleep makes stress and irritability worse the next day. Over time, needing a drink to relax can turn into needing more. Try other ways to unwind in our stress management techniques.

Alcohol plus sleep medicine, anxiety medicine, opioid painkillers or some allergy medicines can slow breathing and be deadly. Alcohol plus cannabis or energy drinks can hide how impaired you are. Read medicine labels and ask a pharmacist.

The minimum legal drinking age is 21 in every state. Teen brains are still developing, and people who start drinking young are more likely to have problems with alcohol later.

Over time, drinking raises the risk of liver disease, heart problems, several cancers, depression and injury. In 2025, the U.S. Surgeon General issued an advisory on the link between alcohol and cancer risk. Less is better.

Call 911 right away if someone who has been drinking has any of these:

• Confusion, or you can't wake them up
• Vomiting while passed out or very drunk
• Seizures
• Slow breathing (fewer than 8 breaths a minute) or long gaps between breaths
• Clammy, bluish or very pale skin; low body temperature

While you wait: don't leave them alone, keep them sitting up or on their side, and don't give them coffee or a cold shower.

Answer yes or no for the past year:

1. Have you ended up drinking more, or longer, than you planned?
2. Have you wanted to cut down but couldn't?
3. Has drinking caused problems at home, work or with the law, and you kept drinking?
4. Have you gotten into fights, said hurtful things, or made choices you regret while drinking?
5. Have you needed more to feel the same effect?
6. Have you felt shaky, sweaty, anxious or sick when alcohol wore off?

This isn't a diagnosis. But if you answered yes to two or more, it's worth talking to a doctor, or calling the free, confidential SAMHSA National Helpline at 1-800-662-4357, any time of day.

1. Count. For one week, write down every drink, in standard drinks. Most people are surprised.
2. Set a limit before you start: how many, and a stop time. Tell someone.
3. Slow down. Alternate each drink with water or a soda. Eat first.
4. Know your triggers. Certain people, places, feelings or times (payday, after a fight). Plan an alternative for each.
5. Set alcohol-free days each week, and a no-alcohol rule on hard days and before driving.
6. Get support. A friend, a doctor, a support group, or the SAMHSA Helpline. If you've been drinking heavily every day, don't stop suddenly on your own: withdrawal can be dangerous. Talk to a doctor first.
