If you choose to drink, drink responsibly. You can reduce your risk of an alcohol-related problem and still have fun with just a little education. 

Lower-risk drinking tips 

Reduce your risk of experiencing an alcohol-related problem:

Eat before drinking: Food slows the rate of alcohol absorption. 
Reduce the rate at which you drink: Sip, don’t gulp! 
Keep track of how much you are drinking. Use an app such as Alcodroid Alcohol Tracker or Drink Control 
Avoid mixing alcohol with other drugs 
Alternate booze with nonalcoholic beverages to pace yourself and stay hydrated. 
Avoid sexual activity as decision-making skills and judgment may be impaired. Consider a “rain check” for a later date. 
Plan a sober way home, a rideshare or a designated driver who has consumed no alcohol. 

Setting a drinking limit

A “standard drink” refers to an alcoholic beverage that your body can process in about one hour. 
How much you pour for a standard drink depends on how concentrated your alcoholic beverage is.  
The higher the alcohol percentage, the less we pour for a standard drink size.  
Not all alcoholic beverages fit into these neat categories; some products contain higher concentrations of alcohol. To calculate the standard drink size for different alcohol products outside of the concentrations above, use this calculator.
Try to stick as close to one standard drink per hour as possible to reduce your risk of negative outcomes
Standard drink

Moderate drinking 

Moderate drinking is associated with fewer negative health outcomes. 
Aim for a limit under 4 drinks in 2 hours as a general guideline.  

Binge drinking

Considered a riskier form of drinking, in which a person consumes enough alcohol to reach a Blood Alcohol Concentration (BAC), of 0.08% or more. 
For individuals assigned female at birth*, this typically occurs after consuming 4 or more drinks in a 2-hour period.  
For individuals assigned male at birth*, this typically occurs after consuming 5 or more drinks in a 2-hour period. 
Avoid binge drinking to limit your risk of negative outcomes, including riskier sexual behaviors, accidents/injuries, and organ damage over time. 

*Assigned sex at birth is used only to help determine BAC and how alcohol may affect your body based on physiology. 

For all individuals, we recommend speaking with your doctor for personalized information about the impact of substances on your body.   

Blood Alcohol Concentration (BAC) & impairment

BAC:

  • Measurement of how much alcohol is in a person’s bloodstream.  
  • Indicates how impaired a person is from drinking  
  • Can rise quickly as a result of: 
    • Food: if a person drinks on an empty stomach, the alcohol will be absorbed into their bloodstream faster. This results in a sudden spike in BAC
    • Rate of consumption: the faster a person drinks, the quicker their BAC will rise. This is because the liver needs time to process the alcohol (about one hour per standard drink). Drinking games can be dangerous, as they encourage individuals to drink a lot of alcohol in a short amount of time
    • Weight: people who weigh less will have a higher BAC than those who weigh more, even if they drink the same amount of alcohol
    • Sex: sex assigned at birth impacts an individual’s BAC

Note: a person can develop a tolerance to alcohol. This means a person would need to drink more alcohol to feel the effects they used to feel. Tolerance can be dangerous, as BAC still rises at the same rate even if a person doesn’t feel the effects. 

Blood alcohol concentration (BAC)

The National Institute on Alcohol Abuse and Alcoholism (NIAAA) chart can be used to help estimate what a BAC might be depending on sex assigned at birth, weight, and number of drinks consumed after one hour of drinking.

Drinking and medications 

If you are taking prescribed or over-the-counter medications, talk with your doctor about possible interactions.   

Mixing alcohol with certain medications can:  

Reduce medication effectiveness 
Intensify impairment and cause side effects like vomiting, loss of consciousness, and breathing difficulties  
Increase the risk of overdose  
Commonly used medications and their interactions with alcohol 

Alcohol poisoning  

  • Signs of alcohol poisoning:
    • Puking while passed out 
    • Being unresponsive to normal attempts to awaken 
    • Noisy, slow, shallow, or stopped breathing 
    • Blue, cold, or clammy skin 
    • Seizure 
  • Set limits and pace yourself to help prevent alcohol poisoning 
  • One of these signs can indicate alcohol poisoning  
  • If you suspect someone is suffering from alcohol poisoning, call emergency services:
    • Off campus, call 911. 
    • On campus, call EST at (314) 935-5555. 
  • WashU has a Medical Amnesty and Bystander Protocol to reduce barriers to calling for help

Recognizing a problem 

Signs that a person might be drinking too much

You drink more or for a longer period of time than you intended
You attempt to cut down/stop drinking, but cannot
You continue to drink even though it causes health issues 
Loved ones have made comments about your drinking habits
Your drinking interferes with daily activities and relationships
You have experienced withdrawal symptoms when not drinking (ex: shakiness, sweating, anxiety, insomnia, etc.)

If you think that you or someone you know might have an alcohol problem, it is important to see a doctor or mental health provider. If you are concerned about a friend’s substance use, check out our tip sheet for starting a conversation. in our digital library.
