Kanna, a natural plant from South Africa, has gained popularity for its mood-enhancing and anxiety-relieving effects. If you’re new to kanna or considering trying it, you might be wondering: How long does kanna stay in your system?
Understanding the duration of its effects, how your body processes it, and what to expect if you’re subject to drug testing can help you use kanna safely and confidently. This article breaks down everything you need to know in simple terms.
Table of Contents
Kanna effects usually last between 2 to 6 hours, with onset and intensity depending on the method of consumption.
It typically stays in your system for 24 to 48 hours, though most drug tests do not screen for kanna.
While kanna is generally safe, it may interact with medications that affect serotonin—so use with caution.
Kanna (Sceletium tortuosum) is a succulent plant native to South Africa, traditionally used by indigenous groups for its calming and euphoric properties. It contains active compounds like mesembrine and mesembrenone, which act as serotonin reuptake inhibitors (SRIs) and PDE4 inhibitors—affecting mood, stress response, and cognition.
While kanna is not a psychedelic, it’s often used for its uplifting, anti-anxiety effects. Depending on how it’s consumed, kanna can promote relaxation, sharpen focus, or enhance social interactions.

Kanna’s effects are short to moderate in duration. Here’s what to expect by method:
Sublingual (under the tongue): Fast onset, lasting ~2–4 hours
Snuff or nasal:Rapid onset, intense but shorter—~1–3 hours
Capsules or tea:Slower onset, longer-lasting—up to 6 hours
Smoking or vaping:Quick effects that fade within 1–2 hours
Most users feel the peak effects within the first 90 minutes, followed by a gentle taper.
There’s limited formal research on how long kanna stays in your system, but based on its active compounds and user reports, it’s believed to be cleared from the body within 24 to 48 hours.
Key factors that influence how long kanna stays in your system include:
Dosage (higher doses may linger longer)
Frequency of use (regular use may increase retention)
Your metabolism and body weight
Since kanna is not fat-soluble like THC, it likely doesn’t accumulate in fat tissue and doesn’t stay in your system for extended periods.
Kanna is not commonly tested for in standard drug panels (like 5-panel or 10-panel urine tests), which typically screen for:
THC
Cocaine
Opiates
Amphetamines
PCP
There’s currently no evidence that kanna or its alkaloids trigger a false positive on common drug tests. However, if you’re undergoing specialized testing for psychiatric meds or unknown substances, it’s wise to disclose kanna use.
If you're in the military or under strict employment drug policies, it's best to err on the side of caution. While kanna isn’t a scheduled substance in the U.S., its serotonin-affecting properties might raise concerns in regulated environments.
Kanna can produce a variety of effects depending on the dose and format.
Enhanced mood and sociability
Mild euphoria
Improved focus or calm alertness
Occasionally, sedation at higher doses

Some people may feel residual after-effects, such as calmness or light fatigue, especially after large doses.
There’s no indication that kanna builds up in the body with occasional use. However, regular high-dose usage could hypothetically lead to serotonin-related side effects or tolerance over time.
For safety, especially if you're taking SSRIs, MAOIs, or other medications, avoid daily kanna use without guidance from a healthcare provider.
If you’re hoping to minimize how long kanna remains active or detectable, consider these tips:
Hydrate well to support liver and kidney function
Limit dosage to reduce metabolic load
Avoid combining with other substances that slow metabolism
Exercise to support healthy elimination (though kanna is not stored in fat like THC)
In moderate doses, kanna is generally well tolerated. That said, you should avoid using kanna with certain medications, especially:
SSRI or SNRI antidepressants
MAOIs
Benzodiazepines or opioids
Combining kanna with serotonergic drugs may raise the risk of serotonin syndrome, a potentially serious condition.
If you’re wondering how long kanna stays in your system, the answer is: typically 1 to 2 days, with effects wearing off within a few hours. It’s unlikely to show up on drug tests, and it clears from the body relatively quickly—especially with responsible, occasional use.
While kanna can be a natural way to ease anxiety or elevate your mood, it’s important to respect its potency and interactions. Start low and go slow with your dosage, and be mindful of your body’s response.
Most of kanna’s compounds are eliminated within 24–48 hours, depending on your metabolism and dosage.
Unlikely. Standard drug panels don’t test for kanna, and no known cross-reactions exist.
The active effects last 2 to 6 hours, depending on how it’s consumed.
Kanna is not considered physically addictive, but some users may develop a psychological habit if overused.
Yes.Kanna is legal and unscheduled in most parts of the United States, but always check your local laws.
