Is alcohol a hallucinogen? In short, no. But, alcohol is a drug, and it does affect the brain similarly to how hallucinogens do, changing how certain sensations are perceived and impacting motor function. Some people combine alcohol and hallucinogens for a more intense “buzz.” This is extremely dangerous and should be avoided at all costs. Keep reading to learn more.

How Does Alcohol Affect the Brain?
Alcohol impacts brain function much more severely than most people realize. Several studies  show a link between excessive alcohol use and damaged brain function, leading to conditions like:
- Learning deficits
- Memory problems
- Mental disorders
- Other forms of cognitive damage
When excessive alcohol use continues for a prolonged period, the brain can suffer permanent impairment. The good news is, with treatment, you can reverse the damage and start to heal your brain.
When large amounts of alcohol are consumed over a long period, it can produce deadly effects as the drug impacts:
- Several regions of the brain
- The Central Nervous System, including the brain, nerves, and spinal cord
What’s more, alcohol’s depressive properties have the ability to suppress breathing and lower body temperature to dangerous and even life-threatening levels.
If you don’t consider yourself a ‘binge drinker,’ you may be breathing a sigh of relief right now. But, unfortunately, that sigh of relief will be short-lived. Even short-term alcohol use impacts the parts of the brain that control cognitive and motor functions and causes them to slow down. Anybody who has drank alcohol before knows how alcohol impairs memory, judgment, coordination, and sleep.
The stages of alcohol intoxication as they relate to brain function are as follows:
- Subliminal intoxication — The first stage of intoxication happens when your BAC reaches between 0.01-0.05. Although you may not appear “drunk,” your reaction time, behavior, and judgment are all beginning to be altered. It takes the average person only one drink to enter this initial stage of intoxication.
- Euphoria — Once you’ve had your first drink, your brain begins to release more dopamine, the chemical that’s linked to pleasure . This explains why people love the initial buzz that comes with drinking. Although you will likely feel happy, calm, and confident, your reasoning and memory are becoming more impaired as you continue to drink.
- Excitement — Once your BAC reaches between 0.99 to 0.25, you are legally intoxicated, and the brain’s occipital lobe, temporal lobe, and frontal lobe are all being impacted. The more you drink, the more side effects you’ll see from each lobe, including blurred vision, impaired judgment, and slurred speech.
- Confusion — During this level of intoxication, you’ve become disoriented as the cerebellum, the part of the brain associated with coordination, is affected. This is why drunk people stumble. This is also the stage where blackouts happen as the hippocampus, the part of the brain where new memories are made, is not performing optimally.
- Stupor — Once the BAC reaches 0.25, concerning signs of alcohol poisoning crop up as all mental, physical, and sensory functions become severely impaired. In this stage, the risk of passing out, suffocating, and being injured skyrockets.
- Coma — You are at risk of entering a coma during this stage when the BAC gets to 0.35 due to the compromised breathing and circulation, reflexes, and responses that the alcohol has caused. During this stage, you are at risk of dying.
- Death — If your BAC bypasses 0.45, you risk death by alcohol poisoning or the brain failing to control your body’s vital functions.
How Do Hallucinogens Affect the Brain?
Similar to alcohol, hallucinogens impact the brain in concerning and potentially life-threatening ways, including by:
- Interfering with activity in the prefrontal cortex — This part of the brain is responsible for helping us process complex thoughts and information, set and accomplish goals, stay focused, manage emotional stress, and plan for the future. When hallucinogens interfere with this activity, people have a hard time focusing, processing information, and paying attention. For example, instead of perceiving a wall as a blank white wall, someone on hallucinogens may perceive it as a hot pink wall that’s flashing blue. As the cognition levels drop, people stay in this hallucinatory state until the drug wears off.
- Interfering with the brain’s neural circuits that use serotonin — Groups of neurons working together to carry out brain functions are referred to as neural circuits . Hallucinogens interfere with the neural circuits that use serotonin, which start to impact all functions that rely on serotonin. As this happens, the user’s mood, appetite, body temperature, and sleep patterns all change. They may also experience difficulty controlling their muscle movements and their sensory perception declines, making them experience:
- Visual disturbances
- Glutamate level disruption — Glutamate is a brain chemical that works to regulate a wide range of functions, including learning, emotions, response, and pain perception. This disruption causes people to have abnormal responses to their environments, most commonly in the form of dissociative effects. For example, feeling as if bugs are crawling on their skin and even hallucinating the bugs crawling on them, or feeling as if they’re floating.
Long term effects of hallucinogens on the brain include:
- Persistent psychosis — which causes paranoia, mood swings, disorganized thinking, and visual disturbances 
- Hallucinogen Persisting Perception Disorder (HPPD)
What Can Happen if You Mix Alcohol and Hallucinogens?
The effects of hallucinogens are unpredictable. Remember, alcohol is a drug, so it can also be hard to predict what will happen each time someone drinks an excessive amount.
So, it’s impossible to predict exactly how each hallucinogen will react with alcohol. But, we do know one thing, the combination is high-risk and can be deadly. Symptoms of mixing the two substances include:
- Feeling faint
- Increased heart rate
- Lost consciousness
- Dangerously high body temperature
- Increased chance of suffering a “bad trip,” in which scary hallucinations and extreme depression happen
