Dangerous Combination
Alcohol + Amphetamine is classified as unsafe. Amphetamine masks alcohol's sedative effects, leading to dramatically increased alcohol consumption without feeling drunk. This often results in dangerous levels of alcohol intake and severe hangovers. The stimulant wears off before the alcohol, causing sudden severe intoxication. Dehydration risk is compounded. Also increases cardiac stress.

Adderall (amphetamine) and alcohol is one of the most common dangerous combinations, particularly among college students and young professionals. The core danger is deceptively simple: Adderall masks the feeling of being drunk without reducing the actual physical impairment. You feel sober, alert, and functional while your blood alcohol level continues to climb. This leads to drinking far more than you otherwise would, dramatically increasing the risk of alcohol poisoning, blackouts, and dangerous decisions.
A 2013 study found that college students who mixed Adderall with alcohol were significantly more likely to binge drink and experience alcohol-related consequences. The combination is not a "hack" for drinking more -- it's a trap.
The experience feels like a supercharged version of being drunk: the confidence and social ease of alcohol combined with the focus and energy of Adderall. You feel sharp, talkative, and alert despite consuming drinks that would normally have you slurring and stumbling. The Adderall overrides the sedation and cognitive impairment signals that normally tell you to stop drinking.
The dangerous part: you don't realize how intoxicated you actually are. The stimulant masks the depressant's warning signs, but your liver is still processing the same amount of alcohol. When the Adderall wears off (and it will wear off first if you've been drinking for hours), the full weight of the alcohol hits at once. This is when blackouts, falls, and alcohol poisoning typically occur.
Amphetamine increases dopamine and norepinephrine release through VMAT2 reversal and reuptake inhibition at DAT and NET. This produces wakefulness, focus, and euphoria. Alcohol is a GABAergic depressant that impairs cognition, coordination, and judgment.
The combination creates a pharmacological tug-of-war. The stimulant masks the subjective feeling of intoxication without protecting the body from alcohol's toxic effects. The cardiovascular system is under particular stress: amphetamine increases heart rate and blood pressure while alcohol causes vasodilation. This push-pull on the cardiovascular system increases the risk of heart rhythm abnormalities.
Amphetamine is also hepatotoxic at high doses, and alcohol adds additional liver burden. Both substances are dehydrating.
The mask effect: Feeling alert and sober while actually intoxicated. This is the primary risk factor because it leads to drinking 2-3x more than you would without the stimulant.
Cardiovascular stress: Elevated heart rate from amphetamine + vasodilation from alcohol = irregular heartbeat risk, chest pain, and in rare cases, cardiac events.
Extreme dehydration: Both substances are diuretics. Combined dehydration can cause headaches, dizziness, and in severe cases, kidney stress.
The crash: When the Adderall wears off before the alcohol, you go from feeling alert to extremely drunk in minutes. This sudden onset of intoxication is disorienting and dangerous.
Blackouts: Significantly more common with this combination because blood alcohol levels reach higher levels than they would without the stimulant mask.
| Substance | Solo Dose | Combo Dose | Route |
|---|---|---|---|
| Amphetamine (Adderall) | 10-30 mg | Therapeutic dose only mg | Oral |
| Alcohol | 3-5 drinks standard drinks | 1-2 drinks max standard drinks | Oral |
This combination should be avoided. The fundamental problem -- stimulants masking alcohol intoxication -- cannot be solved with dose management. Even at therapeutic Adderall doses, the masking effect leads to drinking more.
If someone takes Adderall therapeutically (prescribed) and plans to drink: - Do not take an extra dose of Adderall to "handle" the alcohol - Limit alcohol to 1-2 drinks maximum, counting explicitly - Eat a full meal before drinking - Set a hard stop on alcohol consumption regardless of how sober you feel - Remember: feeling sober does not mean you are sober
Typical college scenario (illustrates the danger):
T+0:00 -- Take Adderall (20mg IR).
T+0:30 -- Adderall kicks in. Feel focused, energized.
T+1:00 -- Start drinking at a party. Feel great.
T+2:00-4:00 -- Continue drinking. Feel surprisingly sober despite 4-6 drinks. Think: "I can handle more."
T+4:00-5:00 -- Adderall begins to wear off. Suddenly feel very drunk. This is the danger window.
T+5:00+ -- Full alcohol effects hit. Potential blackout, nausea, loss of coordination.
The next morning: Severe hangover, dehydration, possible memory gaps, regret.
If you take Adderall therapeutically and want to drink socially: eat a full meal first, set a strict 2-drink maximum before you start, alternate every alcoholic drink with water, and tell a friend your limit so they can hold you to it. Do not rely on how you feel to gauge intoxication -- count drinks instead.
You are drunker than you think. This is the single most important thing to understand about this combination. Feeling alert and sober does not mean your blood alcohol is safe.
Do not drive. Your reaction time and judgment are impaired by alcohol even if the Adderall makes you feel alert.
Count your drinks. Do not use subjective feeling to gauge intoxication. Set a number before you start and stick to it.
Hydrate aggressively. Both substances are dehydrating. Drink water between every alcoholic drink.
Eat before and during. Food slows alcohol absorption, which is especially important when the stimulant is masking intoxication signals.
Cardiovascular warning signs: Chest pain, racing heart, heart palpitations, shortness of breath -- stop drinking immediately and seek medical attention.
The crash is real. When the Adderall wears off, have a plan: be somewhere safe, not driving, with people who know your situation.
Adderall and alcohol is a trap. You feel completely sober after 6 drinks and then the Adderall wears off and you're absolutely hammered out of nowhere.
I blacked out for the first time in my life mixing Adderall and alcohol at a party. I felt fine all night until suddenly I wasn't.
The trick is to NOT use your feelings as a gauge. Set a 2-drink max before you go out and stick to it no matter how sober you feel.
My cardiologist told me point blank to never combine these. The heart doesn't like being pushed and pulled at the same time.
