THC, the psychoactive compound found in marijuana, may also increase blackouts when combined with alcohol. Like alcohol, sedatives can impair your ability to think and make memories. This causes your body to slow down and become more relaxed. That’s because benzodiazepines like alprazolam (Xanax), and opioids like oxycodone (Ox圜ontin), activate the GABA neurotransmitter. Taking sedatives while also consuming alcohol can increase the likelihood that you’ll black out. This could cause them to choke and suffocate on their vomit.Ī blackout also makes you more susceptible to injury, such as from a fall or car crash. A person who has blacked out or overdosed on alcohol could throw up while sleeping due to the loss of reflex control. According to the National Institute on Alcohol Abuse and Alcoholism, alcohol delays signals in the brain that control the gag reflex and other autonomic responses. Having even one blackout can be dangerous. It’s thought that binge drinking can impair this part of your brain.īinge drinking can affect your ability to: Regular damage to the frontal lobe can impair your behavior and personality, how you perform tasks, and how you keep information. The frontal lobe also plays a role in short-term and long-term memory formation and recall. ![]() This is the part of the brain that controls cognitive function. It’s thought that chronic alcohol consumption can harm the frontal lobe. These effects range in severity from momentary “slips” in memory to permanent, debilitating conditions. Heavy drinking may have lasting effects on the brain. This seemingly aware state can make it difficult for other people to recognize if a person is in a blackout. They just can’t record any of the memories. They can still eat, walk, hold conversations, have sex, drive, and get into fights.

It’s important to remember that a blackout isn’t the same as passing out. This means it can’t create memories when a blackout occurs. The hippocampus can’t develop long-term alcohol toleration. The hippocampus is found deep within the brain. Although this part of the brain can build up long-term tolerance to alcohol, this isn’t true of the hippocampus. The reward pathway in the brain regulates these activities. It also lowers inhibition, hinders impulse control, and affects decision-making. What happens to the body during a blackout?Īlcohol impairs your ability to walk, speak, react, and remember events. It all comes down to the amount of alcohol in each drink you’ve consumed and the way the alcohol affects you. It’s important to note that there isn’t a set number of drinks that can trigger a blackout. There are several factors that can affect your blood alcohol level, including: You may not have any memory of the time that’s passed when your blood alcohol content is above that threshold. ![]() One study estimated that the odds of experiencing a blackout is about 50% when blood alcohol content reaches 0.22 percent. The amount of memory loss varies from person to person. It doesn’t erase memories formed before intoxication.Īs you drink more alcohol and your blood alcohol level rises, the rate and length of memory loss will increase. Alcohol impairs your ability to form new memories while intoxicated.
