Kanna (Sceletium tortuosum) is a South African succulent with a long history of traditional use for mood enhancement and stress relief. Now available in various forms in smoke shops, kanna has gained popularity for its unique effects. Here's what you need to know.
What Is Kanna?
Kanna is a succulent plant native to South Africa, where it's been used by indigenous peoples for centuries. The San and Khoikhoi people traditionally fermented and chewed it for mood elevation, hunger suppression, and stress relief.
Active Compounds
- Mesembrine: The primary alkaloid; a serotonin reuptake inhibitor (SRI)
- Mesembrenone: Additional alkaloid with SRI and PDE4 inhibitor activity
- Mesembrenol: Contributes to overall effect profile
- Tortuosamine: Minor alkaloid
How Kanna Works
Kanna's primary mechanism is as a natural serotonin reuptake inhibitor (SRI):
- Increases serotonin availability in the brain
- Also inhibits PDE4 (an enzyme associated with mood regulation)
- Effects are milder than pharmaceutical SRIs
- Onset is faster than pharmaceutical antidepressants
Important: Because it affects serotonin, kanna has significant drug interactions (see Safety section).
Effects of Kanna
What to Expect
- Mood elevation: Improved sense of wellbeing
- Reduced anxiety: Calming without heavy sedation
- Increased sociability: Some report being more talkative and open
- Mild euphoria: Pleasant feelings, especially at moderate doses
- Stress reduction: Better ability to handle stressors
Dose-Dependent Effects
- Low doses: Mild stimulation, mood lift, focus
- Medium doses: Stronger mood elevation, euphoria, sociability
- Higher doses: More sedating, potentially introspective
Duration
- Onset: 15-30 minutes (insufflation faster)
- Peak: 1-2 hours
- Total duration: 1-4 hours depending on method and dose
Methods of Consumption
Sublingual (Under Tongue)
Most common method:
- Place extract powder or chewed plant material under tongue
- Hold for 5-10 minutes, then swallow
- Allows direct absorption into bloodstream
- Good bioavailability
Insufflation (Snorting)
Faster onset but shorter duration:
- Use finely ground extract powder
- Effects within minutes
- Can cause temporary nasal discomfort
- Popular for social situations
Oral/Swallowed
- Capsules or mixed with drink
- Slower onset (30-60 minutes)
- Lower bioavailability than sublingual
- Convenient and easy to dose
Smoking/Vaporizing
- Possible but less common
- Very fast onset
- Short duration
- Harsh on throat for some
Dosing Guidelines
Extract Powder (Standardized)
- Low: 25-50mg
- Medium: 50-100mg
- Higher: 100-200mg
Raw Plant Material
Requires higher amounts due to lower alkaloid content—follow product-specific directions.
Start Low
Kanna affects people differently. Start with a low dose and increase gradually. First-time users often feel little effect—this is normal and doesn't mean it "doesn't work."
Safety Considerations
Drug Interactions (CRITICAL)
Because kanna is an SRI, it can interact dangerously with:
- SSRIs/SNRIs: Risk of serotonin syndrome—potentially dangerous
- MAOIs: Potentially dangerous interaction
- Tramadol: Increased seizure risk
- Other serotonergic substances: MDMA, certain opioids, etc.
Do not use kanna if you take antidepressants or other psychiatric medications without consulting a healthcare provider.
General Precautions
- Don't drive or operate machinery until you know how kanna affects you
- Avoid alcohol combination (amplified effects)
- Not for pregnant or nursing women
- Not for those with heart conditions
Side Effects
- Headache (especially with high doses or dehydration)
- Nausea (usually from higher doses)
- Mild appetite suppression
- Occasional anxiety in sensitive individuals
