It's the first thing anyone asks about kava, usually with a slightly hopeful expression. The answer is more interesting than a straight yes or no, because kava sits in a category most people don't have a word for.
No, kava doesn't get you high the way cannabis or alcohol does. There's no euphoria to chase, no distorted perception, no altered sense of time, and your thinking stays clear throughout.
What kava is, though, is psychoactive: it changes how you feel by acting on your nervous system, producing deep physical relaxation and a quiet mind.
At heavy doses it does become genuinely impairing, just not in a way anyone would describe as fun.
Here's the distinction that actually matters, plus the drug-test question everyone's really asking.
Psychoactive, but not intoxicating
Kava changes how you feel without producing a recreational high. There's nothing to chase and no buzz to build on.
Quick Takeaways
- Kava is psychoactive but doesn't produce a cannabis- or alcohol-style high.
- No perceptual changes, no time distortion, no impaired judgment at normal doses.
- Heavy doses are impairing, but wobbly and sleepy rather than euphoric.
- Kava isn't screened for on standard drug tests.
- It can, however, trigger a false positive for amphetamines on an initial screen.
Does Kava Get You High?
Not in the sense people mean by the word. Kava has no recreational ceiling to climb toward.
With cannabis or alcohol, more produces a different and often more intense state, which is what "getting high" describes. Kava doesn't work that way.
Take a moderate amount, and you feel relaxed and sociable.
Take considerably more, and you don't get higher; you get sleepy, wobbly, and eventually nauseous. The curve flattens and then turns unpleasant.
That's why kava never really established itself as a recreational drug outside its traditional context, despite being legal, widely available and psychoactive. There isn't much of a party in it.
Psychoactive vs Intoxicating: The Difference That Matters
These two words get used interchangeably, and confusing them is why this question is so muddled.
Psychoactive means it changes how you feel. Intoxicating means it impairs how you function.
Caffeine is psychoactive. So is chamomile, in a mild way. Neither gets you high. Kava is firmly in that category at ordinary doses: it alters your mental state toward calm without clouding judgment, distorting perception or affecting your ability to think straight.
Alcohol and THC are both psychoactive and intoxicating. Kava is the former, and only becomes meaningfully the latter when you significantly overdo it.
What Kava Does Instead of a High
The experience is closer to the feeling of a weight coming off than to anything recreational.
What you do get
- Muscles releasing tension
- Mental chatter going quiet
- Mild lift in mood
- Easier, warmer conversation
- A numb, tingling mouth
- Clear thinking throughout
What you don't get
- Euphoria you'd chase
- Visual or perceptual changes
- Distorted sense of time
- Impaired judgement
- Memory gaps or blackouts
- Paranoia or anxiety spikes

Why Kava Isn't Like THC or Alcohol
Different receptors, different outcome. The pharmacology explains the whole thing.
THC produces its effects by binding cannabinoid receptors, which is what generates the altered perception and time distortion people associate with being high.
Alcohol boosts GABA while suppressing glutamate and flooding the reward system with dopamine, which is what erodes judgment and drives its addictive pull.
Kava's kavalactones enhance GABA-A activity, block sodium and calcium channels, and reversibly inhibit MAO-B. No cannabinoid receptors, no opioid receptors, and notably not the benzodiazepine binding site either.
The result is calm without the cognitive cost, which is exactly what the pharmacology would predict.
Can You Take Too Much Kava?
Yes, and the result is instructive: it doesn't get better, it gets worse.
Push well past a sensible amount, and you reach what kava drinkers call being "krunk". That means heavy limbs, wobbly coordination, eyelids you're fighting, a strange sensation when you move your head quickly, and often nausea.
Anxiety typically disappears entirely, which is the appealing part, but the rest is closer to being unwell than being high.
It's uncomfortable rather than dangerous, and it resolves on its own. It's also entirely avoidable by dosing sensibly, which we cover in our guide to kava dosage.
Does Kava Show Up on a Drug Test?
Kava itself isn't screened for on standard drug tests. There's an important complication though, and almost nobody mentions it.
Standard 5-panel and 10-panel urine tests look for substances like THC, opiates, amphetamines, cocaine, and PCP. Kavalactones aren't on those panels, so kava won't show up as kava, and it won't cause a positive for THC, opiates, or benzodiazepines.
Kava can trigger a false positive for amphetamines
A study published in the Journal of Analytical Toxicology documented three patients whose urine screened positive for amphetamine-type substances by immunoassay.
Follow-up testing by GC-MS found no amphetamines at all, but did find kavain, one of kava's main kavalactones.
When researchers tested kava powders and a kavain standard directly against the amphetamine immunoassay, they cross-reacted and produced false positives.
The reassuring part is that an immunoassay is only a preliminary screen. Confirmatory testing by GC-MS distinguishes the actual compounds and clears it.
If you face workplace testing and drink kava, it's worth knowing this can happen so you can ask for confirmatory testing rather than being blindsided.
This was reported as the first such case of kavain causing false-positive amphetamine results, so it isn't a common occurrence. It's simply useful to know it's documented.
Can You Drive After Kava?
The research here is more nuanced than the blanket warnings suggest, but the safe answer is still straightforward.
In a randomized, placebo-controlled, double-blind study using a driving simulator, a medicinal dose of 180mg of kavalactones did not impair driving performance, while 30mg of oxazepam, a benzodiazepine, produced significantly slower braking reactions.
Kava also caused fewer lapses of concentration than the benzodiazepine.
That's a real finding, and it supports the clear-headed reputation.
It doesn't mean driving after kava is fine. Kava-bar servings are frequently much larger than a medicinal dose; heavy amounts visibly affect coordination, and drivers have been cited after big sessions. The sensible rule: if you can feel it, don't drive.
And never drive after combining kava with alcohol.
Is the Kava Buzz Legal?
Yes. Kava isn't a controlled substance anywhere in the US.
It isn't scheduled under the Controlled Substances Act, so possessing or consuming it isn't a criminal matter.
The DEA lists kava as a drug of concern, a monitoring category for substances with psychoactive properties that aren't formally scheduled, which carries no restriction on buying or using it.
Being legal to consume doesn't make you legal to drive impaired, and it doesn't mean the rules are identical everywhere. Selling prepared kava drinks has run into local restrictions in some places, which we cover in our guide to kava's legal status.

Does Kava Get You High? The Bottom Line
Kava is psychoactive but not intoxicating, and that distinction is the answer.
It relaxes your body and quiets your mind without euphoria, perceptual changes, or impaired judgment, which is precisely why it never caught on recreationally.
Overdo it, and you get wobbly and sleepy rather than higher.
It isn't screened for on standard drug tests, though it can produce a false positive for amphetamines on an initial immunoassay that confirmatory testing will clear. Legal to use, sensible not to drive on.
Frequently Asked Questions
Does kava get you high?
Not in the cannabis or alcohol sense. Kava is psychoactive and produces relaxation and calm, but there's no euphoria, no perceptual distortion, and no impaired judgment at normal doses.
Is kava psychoactive?
Yes. It acts on your nervous system to change how you feel, mainly through GABA-A receptors. Psychoactive isn't the same as intoxicating, and kava sits closer to the caffeine end of that spectrum than the alcohol end.
Does kava show up on a drug test?
Kava isn't included on standard 5-panel or 10-panel tests and won't cause positives for THC, opiates, or benzodiazepines. It has been documented to cross-react with amphetamine immunoassays, though confirmatory GC-MS testing clears it.
Can you get drunk on kava?
No. Heavy doses make you sleepy, wobbly and sometimes nauseous, but without the disinhibition, impaired judgment or memory gaps that define being drunk.
Is kava a drug?
It's a psychoactive plant sold in the US as a dietary supplement. It isn't a controlled substance, though the DEA lists it as a drug of concern, meaning it's monitored but not scheduled.
Can you drive after taking kava?
Controlled testing found a medicinal dose didn't impair driving, but kava-bar servings are far larger; heavy doses affect coordination, and citations have been issued. If you feel it, don't drive, and never after alcohol.
Why doesn't kava get you high like other psychoactive plants?
Because of where it acts. Kava works on GABA-A receptors and ion channels rather than cannabinoid or opioid receptors, so it produces calm without the altered perception or reward-system effects that create a high.
Calm, clear, and completely sober.
