Unpacking the Factors Behind Intoxication
Many people believe that different types of alcohol produce different kinds of 'drunk'—a boisterous tequila drunk versus a smooth vodka buzz, for example. However, scientific evidence indicates that these perceived effects are primarily influenced by psychological factors, drinking environment, and the rate of consumption, not the spirit's base ingredients. The key element determining your level of intoxication is the amount of ethanol in your system, which raises your Blood Alcohol Concentration (BAC). Since most standard vodkas and tequilas are bottled at 40% alcohol by volume (ABV), or 80 proof, a standard serving of either contains the same amount of pure alcohol.
The Role of Alcohol Content (ABV)
The primary driver of intoxication is the quantity of ethanol, measured by ABV, that enters your bloodstream. While most standard versions of both spirits contain 40% ABV, there are exceptions. Some high-proof vodkas and tequilas can exceed this, meaning a shot of a 55% ABV tequila will certainly get you drunker faster than a 40% ABV vodka.
- Standard Spirits: Most commercial vodka and tequila brands are 80 proof (40% ABV).
- High-Proof Variations: Specific brands or types, especially barrel-aged tequilas, may be bottled at higher proofs.
- Mixers Matter: What you mix your drink with can also affect intoxication speed. Carbonated mixers, like soda or tonic, can increase the rate of alcohol absorption, making you feel the effects quicker.
The Influence of Congeners
Congeners are complex organic molecules produced during fermentation that give spirits their distinct flavour, aroma, and colour. Clear spirits like vodka are highly distilled and have very low congener content. In contrast, tequila, especially darker varieties like reposado and añejo, contains more congeners.
While congeners don't alter the level of intoxication from the ethanol, they are linked to the severity of hangovers. Studies have shown that drinks with more congeners can lead to more intense hangover symptoms, potentially making drinkers feel worse the next day, which some may mistake for being 'drunker' during consumption.
How Consumption Affects Intoxication
Beyond the drink itself, several personal factors and drinking habits play a significant role in how intoxicated you become.
- Speed of Consumption: The faster you drink, the quicker your BAC rises, and the more intense the effects will be. A round of tequila shots will likely feel more potent and rapid than sipping vodka sodas over the same period.
- Body Weight and Composition: People with a smaller body mass or less muscle have less fluid to dilute the alcohol, leading to a higher BAC and quicker intoxication.
- Food Intake: Drinking on an empty stomach allows alcohol to be absorbed into the bloodstream much faster than if you have food in your stomach to slow the process.
- Tolerance and Expectancy: Regular drinkers build a tolerance, requiring more alcohol to achieve the same effect. Moreover, if you expect tequila to make you feel rowdy, this expectation can influence your behaviour, a psychological phenomenon known as expectancy.
Comparison Table: Vodka vs. Tequila for Intoxication
| Feature | Vodka | Tequila |
|---|---|---|
| Standard ABV (Proof) | Typically 40% (80 proof) | Typically 40% (80 proof), but can range higher |
| Primary Intoxicant | Ethanol | Ethanol |
| Congener Content | Very low (highly filtered) | Higher, especially in darker, aged types |
| Flavor Profile | Neutral, allowing mixers to dominate | Complex, from earthy to smoky |
| Perceived 'Drunk' | Often associated with a more neutral, predictable high | Can be associated with a more energetic, or wild high due to context |
| Hangover Potential | Lower, due to minimal congeners | Higher, due to higher congener content |
Practical Implications for Drinking
The perception that tequila makes you 'drunker' is likely rooted in how it is traditionally consumed. Tequila is often taken as shots during celebrations, leading to rapid alcohol intake and a sudden spike in BAC. In contrast, vodka is more commonly mixed into cocktails and sipped over a longer period, resulting in a slower rise in intoxication.
Ultimately, whether you choose vodka or tequila, the most important factors for controlling your level of drunkenness are moderation and mindful consumption. Pay attention to the ABV of your chosen spirit, avoid drinking on an empty stomach, and be aware of your personal tolerance levels. Responsible drinking is the key to managing intoxication, regardless of the bottle's contents.
Conclusion
To answer the question, "Does vodka or tequila get you drunker?", the most accurate response is that they don't, assuming equal alcohol content and consumption. The amount of pure alcohol (ethanol) you consume is the sole determinant of your intoxication level. While congeners in tequila can contribute to a worse hangover, they do not inherently make you more drunk during the consumption period. Personal factors, such as speed of consumption, food intake, and your own body's metabolism, are far more significant than the choice between these two spirits. The best practice for a responsible night out is to monitor your intake and be aware of how external factors influence your experience, rather than relying on folklore about specific liquors.

Frequently Asked Questions
Is it true that tequila makes you more energetic than vodka?
No, all types of alcohol, including tequila and vodka, are central nervous system depressants. The perception of different 'drunks' is largely psychological, influenced by the social context and expectation rather than the chemical makeup of the spirit.
What are congeners and how do they affect me?
Congeners are minor chemical byproducts produced during fermentation and aging. They are responsible for a spirit's flavour and aroma and can contribute to a more severe hangover. They do not, however, make you more intoxicated from the ethanol itself.
Why do shots seem to get me drunker than mixed drinks?
Shots typically involve consuming a concentrated amount of alcohol very quickly, causing a rapid spike in your Blood Alcohol Concentration (BAC). Mixed drinks are usually consumed more slowly, allowing your body to metabolize the alcohol at a more gradual pace.
Is 100% agave tequila better for avoiding hangovers?
100% agave tequila contains fewer sugars than 'mixto' tequilas, but it still contains congeners. While it might lessen the severity of a hangover compared to cheaper versions, clear, highly filtered spirits like vodka still have the lowest congener content.
Does drinking on an empty stomach make me drunker?
Yes. Food in your stomach helps slow the absorption of alcohol into your bloodstream. Without food, alcohol passes into your system much faster, leading to a quicker and more intense feeling of intoxication.
How does body weight affect intoxication?
Generally, a smaller person will become more intoxicated than a larger person from the same amount of alcohol. This is because the alcohol is concentrated in a smaller body mass, leading to a higher BAC.
What is the most important factor in how drunk you get?
The most important factor is the total amount of ethanol consumed and the rate at which you drink it. While other factors play a role, the volume and speed of alcohol intake are the primary determinants of intoxication.
