Tequila is not a stimulant. Like every other alcoholic drink, it contains ethanol, which is classified as a central nervous system depressant. There is no compound in tequila, agave-derived or otherwise, that reverses this basic pharmacology. The belief that tequila is “an upper” persists because the real story of how alcohol affects your brain is more interesting than a simple label like “depressant” suggests, and because the way people tend to drink tequila creates a perfect illusion of stimulation.
Why Alcohol Feels Like a Stimulant Before It Doesn’t
Ethanol acts on multiple brain pathways simultaneously, altering activity across several neurotransmitter systems at once.1PubMed. A review on alcohol: from the central action mechanism to chemical dependency The net result is depressant, but the experience along the way is not a straight line downward. Researchers describe alcohol’s subjective effects as biphasic: stimulation comes first, sedation follows.2PubMed Central. The neurobiological markers of acute alcohol’s subjective effects in humans
The timing maps closely to what your blood alcohol level is doing. During the ascending phase, when your blood alcohol concentration is rising, people report feeling more energized, happier, and physically active. One study found that both physical activity and self-reported stimulation increased while blood alcohol was climbing.3PubMed. The biphasic effects of alcohol: comparisons of subjective and objective measures of stimulation, sedation, and physical activity A randomized trial measuring mood after moderate drinking with a meal found a similar split: within the first hour, participants felt happier and more stimulated, with happiness and stimulation scores peaking around the same time blood alcohol peaked, roughly 30 minutes in. After about 90 minutes, the picture reversed. Sleepiness and sedation took over as blood alcohol declined.4PLOS ONE. The Biphasic Effects of Moderate Alcohol Consumption with a Meal on Ambiance-Induced Mood and Autonomic Nervous System Balance: A Randomized Crossover Trial
This is the key to the tequila myth. The stimulating phase is real. It just has nothing to do with tequila specifically. It happens with every alcoholic drink. The reason tequila gets the credit is tied to how and when people drink it.
Spirits Hit Your Bloodstream Faster
One factor that makes tequila feel different from, say, a beer is how quickly spirits raise your blood alcohol level. A controlled study comparing spirits, wine, and beer at equivalent alcohol doses found that peak blood alcohol concentration was reached significantly earlier after drinking vodka and tonic, about 36 minutes, compared to 54 minutes for wine and 62 minutes for beer. Peak levels were also substantially higher after spirits.5PubMed Central. Absorption and Peak Blood Alcohol Concentration After Drinking Beer, Wine, or Spirits
A faster, steeper rise in blood alcohol means a more compressed and intense ascending phase, the exact phase where stimulation lives. Tequila consumed as a shot is about the fastest delivery system for ethanol short of an IV. You get a rapid spike in blood alcohol, a pronounced burst of stimulation, and your brain links that rush to the tequila rather than to the pharmacological mechanics of a steep ascending curve. If you sipped the same amount of ethanol as a light beer over an hour, the stimulation would be far more muted because the ascent would be gentler and the peak lower.
The Dopamine Release Behind the Buzz
Part of the early stimulation comes from dopamine. Even low doses of alcohol can trigger dopamine release in the brain’s reward circuitry, which contributes to the pleasurable, rewarding feelings people associate with drinking.6PubMed Central. Alcohol and dopamine This dopamine burst can reduce negative feelings and satisfy cravings, creating a transient state of elevated mood that feels genuinely energizing.7PubMed. Relationship between dopaminergic neurotransmission, alcoholism, and Reward Deficiency syndrome
Your body also responds to alcohol by ramping up sympathetic nervous system activity. In one study, alcohol increased heart rate from about 59 to 66 beats per minute and boosted sympathetic nerve activity by more than double.8PubMed. Effects of alcohol on sympathetic activity, hemodynamics, and chemoreflex sensitivity Another study confirmed similar increases in heart rate and muscle sympathetic nerve activity after alcohol compared to placebo.9PubMed Central. Influence of acute alcohol ingestion on sympathetic neural responses to orthostatic stress in humans A pounding heart and a surge of adrenaline-related activity feel stimulating because they are stimulating at the peripheral level, even though the brain itself is being depressed. This mismatch between what’s happening in your nervous system and what’s happening in your higher brain functions is part of why the “tequila is an upper” narrative feels true. Your body is genuinely revved up, even as the drug responsible for it is working to sedate your thinking.
The Setting Where You Drink Tequila Matters More Than the Tequila
Think about when people drink tequila. It’s rarely alone on the couch on a Tuesday. Tequila shows up at parties, at bars, in rounds of shots with friends, on vacation. That context is doing enormous work on your subjective experience, and the research on this point is remarkably consistent.
People who drink in social groups report feeling more drunk, more stimulated, and more social than people who drink the same amount alone.10PubMed Central. In the company of others: Social factors alter acute alcohol effects Company and music independently increase both consumption and positive mood, meaning social drinking creates a feedback loop where your surroundings amplify the pleasurable feelings alcohol is already producing.11PubMed. Alcohol and ambience: social and environmental determinants of intake and mood A broader review of the literature concluded that social environments reliably enhance the emotional experience of drinking, with various social and contextual variables shaping how strong the effect is.12PubMed Central. A social contextual review of the effects of alcohol on emotion
The environment isn’t just a pleasant backdrop. It’s part of the pharmacological experience. An early study on this showed that alcohol consumption, the setting you drink in, and your personal expectations about alcohol all have independent and interacting effects on how you feel.13PubMed. Subjective effects of alcohol: the influence of setting and individual differences in alcohol expectancies So if you believe tequila makes you wild, drink it at a loud bar with friends, and do a shot that spikes your blood alcohol fast, the combination of expectation, setting, and steep ascending blood alcohol practically guarantees you’ll feel stimulated. That’s three forces pushing in the same direction, none of which are unique to the liquid in the glass.
Expectations Can Create the Effect All by Themselves
Perhaps the most striking evidence against tequila being pharmacologically special comes from placebo research. In group settings, people given drinks they believed were alcoholic but that contained no alcohol reported feeling intoxicated and stimulated at levels comparable to studies where people drank placebos while alone. The belief rate was almost universal: over 99% of participants who received a placebo in a group setting reported they had consumed alcohol.14PubMed Central. Using Placebo Beverages in Group Alcohol Studies
Even young adolescents with minimal drinking experience already hold different emotional expectations for different types of alcohol, associating certain beverages with certain moods before they’ve had meaningful experience with any of them.15PubMed. Do different drinks make you feel different emotions? Examination of young adolescents’ beverage-specific alcohol expectancies using the Alcohol Expectancy Task These beliefs are culturally absorbed. By the time someone does their first tequila shot, they may have seen hundreds of depictions of tequila as the party drink, the wild drink, the one that “makes you crazy.” Those expectations shape the experience from the very first sip.
Does Agave Chemistry Make Any Difference?
Tequila is made from the blue agave plant, which is a distinctive raw material. Agave plants are a natural source of fructans called agavins, which have been studied as potential functional food ingredients.16ScienceDirect. Processing of Fructans and Oligosaccharides from Agave Plants Tequila also has a complex aroma profile. Analysis of silver tequilas has identified over 70 odorant compounds, including several reported in tequila for the first time.17PubMed. Comprehensive Aroma Characterization of Silver (Blanco) Tequila
None of this translates to a stimulant effect. Agavins are mostly broken down during fermentation and distillation. The aromatic compounds make tequila smell and taste distinctive, but they exist in trace amounts far too small to have a psychoactive effect. The idea sometimes circulated on social media that “100% agave tequila won’t give you a hangover” or “acts differently because of the agave” conflates the raw plant with the finished spirit. By the time distillation is done, the relevant psychoactive molecule is ethanol, same as in whiskey, vodka, or any other spirit.
Congeners and the Hangover Question
One area where different spirits do genuinely differ is in their congener content. Congeners are the chemical byproducts of fermentation and aging: things like methanol, acetaldehyde, and various fusel alcohols. Darker, barrel-aged spirits tend to have more of them. A study comparing bourbon (high in congeners) to vodka (low in congeners) at the same ethanol dose found that hangover ratings were worse after bourbon.18PubMed Central. Intoxication with Bourbon versus Vodka: Effects on Hangover, Sleep and Next-Day Neurocognitive Performance in Young Adults
Where does tequila fit? A blanco (unaged) tequila is relatively low in congeners, similar to vodka. A reposado or añejo, which has spent time in barrels, picks up more. But congeners primarily affect how you feel the next morning, not how stimulated you feel while drinking. And even the hangover connection is not as tidy as it sounds. A separate study examining hundreds of episodes of moderate drinking found that alcoholic beverage type was not associated with whether someone got a hangover at all.19PubMed Central. The incidence and severity of hangover the morning after moderate alcohol intoxication The dominant factor was how much ethanol you consumed, full stop. Congeners may influence severity when a hangover does occur, but the drink choice is a secondary variable at best.
Why Tequila with Energy Drinks Feels Especially Stimulating
Tequila is often mixed with energy drinks, lime-heavy cocktails with sugary mixers, or consumed alongside caffeinated sodas. When caffeine enters the picture, the subjective experience changes. A comprehensive review of studies on mixing alcohol with energy drinks found that the combination increased both stimulation and alertness, offset fatigue from drinking, and made people want to keep drinking longer.20PubMed. A comprehensive review of the effects of mixing caffeinated energy drinks with alcohol
One experimental study that tested this found that combining energy drinks with alcohol improved performance on an attention task compared to alcohol with a placebo drink. However, the subjective measures told a more complicated story: participants still felt just as impaired.21PubMed Central. The effects of energy drink in combination with alcohol on performance and subjective awareness Caffeine masks some of alcohol’s sedating effects without reversing the underlying impairment. If someone drinks a tequila and Red Bull and then attributes their energy to the tequila rather than the caffeine, the myth gets reinforced. The stimulation is real but it came from the mixer, not the agave.
Your Genetics Shape How Stimulated You Feel
Not everyone responds to alcohol the same way, and part of the variation is genetic. Research on a common variant in the gene for the mu-opioid receptor (OPRM1) has found that people carrying the minor G allele experience greater dopamine release in the brain’s reward regions after alcohol and report higher levels of subjective intoxication and sedation compared to those without it.22PubMed Central. Genetic Influences on Response to Alcohol and Response to Pharmacotherapies for Alcoholism This gene variant alone accounted for about 30% of the variance in brain response to alcohol in one imaging study.
What this means practically is that two people can drink the same tequila shot under the same conditions and have genuinely different subjective experiences. One person might feel a stronger reward signal and more euphoria, while another feels more sedated. Neither of them is responding to something special about the tequila. They’re responding to the same ethanol molecule filtered through different neurobiology. When a person who happens to be genetically primed for a strong stimulant response drinks tequila at a party and has an electric night, they attribute the feeling to the drink. If they happened to have been drinking gin, they’d attribute it to gin.
What Alcohol Does to Your Gut
One reason people sometimes feel differently after spirits versus beer or wine has nothing to do with brain chemistry and everything to do with the gastrointestinal tract. Regardless of type, alcohol relaxes the valve at the top of the stomach and can promote acid reflux. But fermented beverages like beer and wine also increase stomach acid production more than distilled spirits do. Low doses of alcohol speed up gastric emptying, while higher doses slow it down and reduce bowel motility.23PubMed Central. The effects of alcohol consumption upon the gastrointestinal tract
If someone switches from beer to tequila shots and feels “lighter” or more energized, it may partly be because they’ve dropped the stomach-distending carbonation and the higher acid secretion that comes with fermented drinks. Feeling less bloated is easily confused with feeling stimulated. The difference is real, but it’s a digestive one, not a neurological one. You’d get the same effect switching to vodka or rum.
The Cultural Engine That Keeps the Myth Alive
The “tequila is an upper” belief is self-reinforcing in a way that makes it almost impossible to debunk through personal experience alone. You believe tequila makes you energized. You drink it in exactly the circumstances most likely to produce stimulation: fast, in a group, at a party, sometimes with caffeine. You feel stimulated. Belief confirmed. The next time, you reach for tequila again when you want to feel a certain way, which means you’re again selecting for the social and behavioral conditions that produce stimulation. People who drink tequila quietly at home and feel sleepy don’t tell that story at brunch.
This feedback loop is powered by what researchers call beverage-specific expectancies, the idea that different drinks produce different emotional outcomes. These beliefs are absorbed culturally before they’re tested personally, and because alcohol is a drug whose subjective effects are genuinely shaped by expectation and context, the beliefs partially create the experiences that seem to confirm them. A placebo study found that people in group settings reported stimulation increases even when they received no alcohol at all.14PubMed Central. Using Placebo Beverages in Group Alcohol Studies If belief alone can produce stimulation without any ethanol, it can certainly steer how you interpret a tequila buzz versus a wine buzz when ethanol is present.
The myth is also commercially useful, which guarantees it keeps circulating. Tequila brands benefit from being associated with energy and excitement rather than sedation and hangovers. Marketing doesn’t need to make an explicit “tequila is a stimulant” claim. It just needs to show tequila in stimulating contexts, and consumers draw the conclusion themselves. The same mechanism has worked for other spirits in other eras: vodka was once “the clean drink,” rum was “the tropical party drink.” The attribution shifts depending on the decade and the brand strategy, but the pharmacology stays exactly the same.
