How Long Does Alcohol Tolerance Last?

May 2, 2023

Alcohol tolerance is the body's ability to handle a certain amount of alcohol without feeling too drunk. This is a useful skill, especially for people who drink regularly and want to feel in control.

Your tolerance is affected by several factors including your age, size and gender. It also depends on the type of alcohol you're drinking.


Tolerance is a physical phenomenon that occurs as you drink alcohol over a period of time. The body begins to metabolize the substance at a different rate than it did when you first began drinking, so more alcohol is needed for a comparable effect.

The brain also changes at a cellular level as the body becomes more tolerant to alcohol. This heightened sensitivity to the drug is called functional tolerance and can lead to alcohol dependence.

People who are tolerant to alcohol often experience few signs of intoxication even when they drink large amounts. If they stop or reduce their alcohol intake, this tolerance could disappear.

Tolerance can be built over time, so it is important to take time to evaluate your drinking habits and decide whether you should continue drinking or reduce your consumption. It is possible to safely lower your tolerance, but you should be careful to do so in a way that does not cause withdrawal symptoms.

Physical Effects

The effects of alcohol on the body can be both short- and long-term. For example, drinking too much can cause alcohol poisoning and increase the risk of injuries. Chronic drinking can also cause damage to the liver and other organs.

Your alcohol tolerance depends on how well your liver can break down and remove the alcohol from your blood. It is influenced by your weight and if you drink regularly.

Some people develop a higher tolerance to alcohol than others. This is because different people have different metabolisms.

It may also be due to the way alcohol affects your brain. GABA, which controls impulsiveness, and glutamate, which stimulates the nervous system, are both affected by alcohol.

Tolerance can be a sign of an underlying addiction or a warning that you are developing an alcohol use disorder. If you have developed a high tolerance to alcohol, you should limit your consumption or seek treatment. This is because alcohol can be dangerous to your health, your job, and your relationships.

Mental Effects

Alcohol tolerance can develop over time, causing a person to need larger amounts of the drink to achieve the same effect as they used to. This can lead to problem drinking.

Psychologists can help individuals with problems involving drinking by using various therapies. These include cognitive-behavioral coping skills treatment and motivational enhancement therapy.

Some psychologists may also use 12-Step facilitation approaches in combination with these treatment options. These interventions can improve a drinker’s ability to cope with high-risk drinking situations and reduce his or her risk of alcohol dependence.

The effects of alcohol on the brain can last a long time, even after a drinker has stopped drinking. This is because the human brain must maintain a delicate balance of neurotransmitters in order to function properly.

Long-Term Effects

Alcohol is a sedative and relaxant, because it increases the brain's levels of GABA (gamma-aminobutyric acid). It also binds to certain receptors on your nerve cells, which helps control your emotions and body temperature.

However, over time, your tolerance for alcohol will grow and you may need more and more to achieve the same effects. This can lead to alcohol use disorder and/or addiction.

A person's ability to metabolize alcohol also plays a role in their tolerance. People who are larger can metabolize more alcohol than smaller individuals.

The effect of alcohol on your BAC or blood alcohol concentration, the amount of alcohol in your system, is related to your weight and how many drinks you drink. The longer you drink, the higher your BAC will be.

Tolerance also can be accelerated by environmental cues, such as the location where you drink. Rats that always received alcohol in the same environment and were accompanied by the same cues developed tolerance to the sedative and temperature-lowering effects of alcohol much faster than rats that received alcohol in a new room and were accompanied by different cues. This type of tolerance is called environment-dependent or learned tolerance.
