Alcohol and Your Wellbeing

Part of your well-being journey is understanding how alcohol or drug use can impact your academic, personal, and social life. This page can provide effective education, prevention, and intervention resources to help reduce the negative impact of alcohol and other drug abuse on the MIT community.


Blood Alcohol Concentration (BAC) refers to the percent of alcohol (ethyl alcohol or ethanol) in a person’s bloodstream.

A BAC of .10% means that an individual’s blood supply contains one part alcohol for every 1000 parts blood.

The desirable effects of alcohol tend to occur in low doses, and the risk of experiencing the undesirable effects of alcohol increases as BAC rises. 

Factors that influence BAC include:

  • the amount of alcohol a drinker consumes
  • the rate at which a person drinks
  • the drinker’s weight and body mass
  • the amount of blood that is mixing with the alcohol
  • gender – women have less of the enzyme that metabolizes alcohol in their stomachs, on average they weigh less and they have less blood volume than men do, even at equal weight.
  • the amount of food in the stomach – a full stomach slows the pace at which alcohol is absorbed. However, eating before drinking will not prevent high BAC’s from occurring.

You can calculate your estimated Blood Alcohol Concentration by using this BAC Calculator. Visit the AmericanAddictionCenters website to learn more about BAC and the effects of alcohol on your body.

This means Alcohol produces two different effects based on dose.

With a BAC of .055% or less: People tend to feel a “buzz”, euphoria, and stimulant effects.

A BAC above .055%: The depressant effects of alcohol kick in – which may result in slurred speech, impairment, loss of memory, sickness, etc.

The Point of Diminishing Returns (BAC of .055) is the point at which drinking more will NOT make you feel better and will only make you more impaired. Any desirable effects of alcohol tend to occur in low doses, and the risk of experiencing the undesirable effects of alcohol increases as BAC rises. Any desirable effects of alcohol tend to occur in low doses, and the risk of experiencing the undesirable effects of alcohol increases as BAC rises.

It is important to factor in tolerance if you are planning to drink. After several drinking occasions, consumption of a constant amount of alcohol produces a lesser effect or increasing amounts of alcohol are necessary to produce the same effect.

BAC is not affected by tolerance. A drinker with a high tolerance may not feel as impaired as they actually are, despite having a high BAC.

Be familiar with the signs and symptoms of alcohol poisoning. If someone exhibits just one, you should get help by calling MIT Police at (617) 253-1212 or DIAL 100 (on a campus phone). MIT’s Good Samaritan Amnesty Policy means we treat this as a health and safety matter, not as a disciplinary incident. The call will be responded to by qualified EMTs and you or your friends won’t get into trouble, no matter how many times you make the call to help a friend.

Signs of alcohol poisoning and drug overdose:

Danger: Call for Help Immediately

  • Unconscious
  • Vomiting while sleeping or passed out
  • Not waking up after vomiting
  • Pale or bluish skin; skin is cold or clammy
  • Breathing irregularly with a few breaths and then nothing for a while
  • Breathing is slow or shallow

Caution: Still Call for Help

  • Unconscious
  • Vomiting while sleeping or passed out
  • Not waking up after vomiting
  • Pale or bluish skin; skin is cold or clammy
  • Breathing irregularly with a few breaths and then nothing for a while
  • Breathing is slow or shallow

MIT strives to empower students to make their own choices about alcohol – we focus on safety by reducing risk. Below are strategies that may help students to enjoy alcohol while minimizing the risk of experiencing negative consequences.

If you choose to drink, consider using these lower-risk drinking strategies:

  • Eat before and while drinking
  • Set a drinking limit near a BAC of .05
  • Keep track of how much you drink by counting “standard drinks”
  • Space drinks over time
  • Alternate alcoholic beverages and drinks without alcohol
  • Mix and measure your own drinks when consuming mixed drinks
  • Avoid or limit shots of hard alcohol
  • Avoid mixing alcohol with energy drinks
  • Avoid drinking games
  • ​​Use a “buddy system” with your friends
