If you’re searching this, you’ve probably noticed something that worries you. Maybe your friend drinks more than everyone else, gets defensive when it comes up, or has started canceling plans and missing responsibilities. The clinical term today is alcohol use disorder (AUD), and it exists on a spectrum from mild to severe. You can’t diagnose your friend, but you can learn to recognize the patterns that signal a real problem.
How Much Drinking Is Too Much
Before looking at behavior, it helps to know where the numbers stand. The NIAAA defines heavy drinking as five or more drinks on any day or 15 or more per week for men, and four or more on any day or eight or more per week for women. One standard drink is 12 ounces of regular beer, 5 ounces of wine, or 1.5 ounces of liquor.
Those numbers are lower than most people expect. A bottle of wine split between two people at dinner is already three drinks each, putting a woman over the daily threshold. If your friend routinely exceeds these levels, that alone doesn’t mean they have AUD, but it does place them in a higher-risk category. A large population study found that drinking roughly 12 or more standard units per week significantly increases the risk of liver disease, including cirrhosis.
Behavioral Signs That Point to a Problem
AUD is diagnosed when someone shows at least two of eleven specific criteria within a 12-month period. Two to three symptoms indicate mild AUD, four to five moderate, and six or more severe. You won’t be checking off a clinical checklist, but knowing these patterns can help you see what’s really going on.
Here are the signs you’re most likely to notice from the outside:
- Drinking more than intended. They say they’ll have one or two, then finish the bottle. Plans for a casual drink turn into a late night more often than not.
- Failed attempts to cut back. They’ve told you they’re going to drink less, done dry January, or switched to beer “to slow down,” but nothing sticks.
- Time lost to drinking. A growing chunk of their week goes to drinking, obtaining alcohol, or recovering from hangovers. Weekends revolve entirely around it.
- Dropping activities. Hobbies, friendships, gym routines, or social commitments they used to care about have quietly disappeared.
- Problems at work, school, or home. Missed deadlines, forgotten obligations, or repeated conflict with family tied to their drinking.
- Continued drinking despite consequences. They keep drinking even though it’s clearly damaging their relationships, health, or finances.
- Risky behavior. Driving after drinking, swimming drunk, or repeatedly putting themselves in dangerous situations while intoxicated.
- Cravings. A visible pull toward alcohol, restlessness when it’s not available, or an inability to relax without a drink.
Two additional clinical signs, tolerance and withdrawal, are harder to spot but worth understanding. Tolerance means your friend needs noticeably more alcohol to feel the same effect. Withdrawal means they experience physical symptoms like tremors, insomnia, nausea, or anxiety when they stop drinking, or they drink specifically to avoid those symptoms. Withdrawal-related sleep problems, mood swings, and fatigue can persist for months even after someone stops.
The “Functioning” Alcoholic Problem
One of the biggest reasons people hesitate to call a friend’s drinking a problem is that the friend still appears to have their life together. They hold a good job, pay their bills, and show up looking put-together. An estimated 20% of people with alcohol addiction fit this profile. Most are described as well-educated with good incomes.
This is exactly why the stereotype of someone who has “hit rock bottom” is misleading. People with high-functioning AUD often rationalize their drinking with logic that sounds reasonable on the surface: “I’m successful, so how can my drinking be out of control?” or “Everyone drinks like I do.” One psychiatrist who specializes in addiction treatment has noted that patients frequently insist no one at work knows about their problem, only to realize during treatment that alcohol had been causing significant professional issues for years. The damage is often invisible to the person doing the drinking long before it’s invisible to the people around them.
If your friend’s drinking bothers you enough to search for answers, trust that instinct. The fact that they still go to work doesn’t cancel out what you’re seeing.
Denial and Why They May Not See It
Denial is one of the most consistent features of problematic drinking. Your friend may genuinely not recognize how much they drink or how many of their problems trace back to alcohol. This isn’t necessarily dishonesty. Alcohol changes judgment, mood stability, and memory, so the person drinking often has the least accurate picture of what’s happening.
You might notice them getting annoyed or defensive when anyone mentions their drinking, feeling guilty about it (sometimes visible in how quickly they justify or explain it), or drinking first thing in the morning to steady themselves. These map directly to a well-known screening tool used in clinical settings, and any one of them is a red flag worth paying attention to.
How to Talk to Your Friend
Confrontation rarely works. Lectures, ultimatums, and listing their failures while they’re drunk will almost always trigger defensiveness and push them further away. What does tend to work is staying connected while being honest.
An evidence-based approach called CRAFT (Community Reinforcement and Family Training) is built around the idea that connection is the opposite of addiction. Rather than cutting someone off or staging a dramatic intervention, CRAFT teaches loved ones to use positive communication and clear boundaries. In practice, that looks like choosing a calm, sober moment to share what you’ve observed without labeling them. Say what you’ve noticed and how it affects you, not what you think they are.
For example: “I’ve noticed you’ve been drinking a lot more this year, and I miss hanging out with you when you’re sober” lands very differently than “You’re an alcoholic and you need help.” The first invites conversation. The second shuts it down.
Set boundaries around what you will and won’t participate in. You don’t have to ride in the car when they’ve been drinking, cover for them when they miss commitments, or pretend everything is fine. Being honest about your limits is not the same as being cruel.
Taking Care of Yourself
Worrying about a friend’s drinking is exhausting, and it can take over your own mental health if you let it. You are not responsible for fixing them. Support groups exist specifically for people in your position. SMART Recovery Family & Friends offers both online and in-person meetings led by trained facilitators who often have personal experience as someone affected by a loved one’s addiction. Al-Anon provides a similar community with a 12-step framework. Both are free and both focus on helping you develop coping strategies, not on controlling the other person’s behavior.
You can love your friend and still recognize that their drinking is beyond what you can solve with worry alone. The most useful thing you can do is stay informed, stay connected, and protect your own well-being while leaving the door open for them to get help when they’re ready.
