Women also produce smaller amounts of enzymes, so the ethanol circulates in their bodies for a longer time. Certain genetic differences have caused different alcohol tolerance levels in many ethnicities. Most of the Asian population doesn’t have ADH, so they can’t metabolize the booze in their bodies. However, these enzymes work at a very slow rate, and they can’t metabolize acetaldehyde at all. Having a mild intolerance to alcohol or something else in alcoholic beverages might not require a trip to a doctor.

Reports showed that individuals who engaged in high-intensity drinking were 70 times more likely to have alcohol-related emergency unit visits than average users. Tolerance does not develop the same way for everybody and for every substance. Some drugs, like benzodiazepines, are highly addictive, and tolerance can be expected to develop within just the first few days of daily use. Other drugs, such as antidepressants, are not known to be habit-forming, and people do not generally develop a tolerance to them. That means they will continue to respond in the same way to the same amount of antidepressant no matter how long they take the medication.

Alcohol Tolerance Explained [CCFA’s Comprehensive Insights]

When someone has had enough to drink, they should be exhibiting some signs of behavioral impairment. If not, their tolerance to alcohol is allowing them to drink increasing amounts of alcohol. You can drink enough alcohol for a period of time that you can develop a tolerance to some of its effects. If you drink long enough, you may find that drinking the same amount you usually drink does not produce the same effect. Alcohol intolerance occurs when your body doesn’t have the proper enzymes to break down (metabolize) the toxins in alcohol. This is caused by inherited (genetic) traits most often found in Asians.

No one should assume the information provided on Addiction Resource as authoritative and should always defer to the advice and care provided by a medical doctor. Alcohol works by manipulating natural chemicals in the brain called GABA (gamma-Aminobutyric acid). GABA is a chemical messenger in the brain, and it’s part of your body’s rest and digest system. GABA binds to its receptors and opens a channel to a negative charge that slows down nervous system activity. Drinking alcohol, which is a chemical called ethanol, enters your brain and binds to GABA receptors.

Alcohol intolerance is caused by a genetic condition in which the body can’t break down alcohol efficiently. The only way to prevent these uncomfortable reactions is to avoid alcohol. how to build alcohol tolerance A lot of people are understandably concerned about their alcohol tolerance, as losing control of your actions and behaviors due to drinking can lead to undesirable results.

  • John C. Umhau, MD, MPH, CPE is board-certified in addiction medicine and preventative medicine.
  • Research has found that alcohol tolerance can be accelerated if drinking over a series of drinking sessions always takes place in the same environment or is accompanied by the same cues.
  • This term refers to the capacity of the body to tolerate or support large amounts of alcohol.
  • Though this type of tolerance might make heavy drinking seem harmless, people with functional alcohol tolerance have a high likelihood of developing alcohol dependence and addiction.
  • Because your drinking increases over time and you could be feeling fine, you might not think of these as being signs of alcohol dependence.

In this post, I will breakdown and discuss mechanisms behind the loss of tolerance towards alcohol and how to rebuild tolerance. Did a night of excessive drinking leave cans or bottles littering your living room floor? If you’re going to engage someone who’s been drinking and shown flashes of violence, don’t do it alone.


Well, it depends because the time required to change tolerance level varies from person to person. Decreasing the number of drinks per week may work for almost everyone; for others, a month without a drink works just fine to reduce someone’s tolerance. The first month is the hardest, but gradually decreasing the number of drinks per week can help bring down the tolerance level without suffering from withdrawals. Children of alcoholics have a high risk of developing tolerance because of exposure to alcohol from a young age.

In fact, this goes against the “listen to your body rule,” because you are artificially tricking it into thinking it’s better off than it is. This can lead to too much drinking, too fast, and serious black-out experiences. You’re also going to be drunker than you think you are and are more likely to do something stupid.
