Standard 5- and 10-panel drug tests do not include kratom alkaloids. Kratom-specific tests (immunoassay for mitragynine) do exist — detection window is approximately 6–9 days for regular users (2020 study). Kratom does not cause false positives on opiate panels — different molecular structure. Check with your testing administrator if you're in an industry that may use expanded panels.

Kava does not appear on standard 5-, 10-, or 12-panel urine drug tests. Kavalactones are structurally unrelated to tested-for substances and don't cross-react with standard immunoassay antibodies. No documented false positives from kava use. Specialized GC-MS tests can detect kavalactones if specifically ordered, but this is not part of routine employment or legal screening.

Kava (GABA-A mechanism) vs kratom (opioid receptor) for relaxation: kava better for social relaxation (maintained clarity + anxiety reduction); red vein kratom better for deep physical/muscle relaxation and heavier sedation. 2013 RCT confirmed kava's anxiolytic effect; 2019 survey confirmed kratom's sedative benefits. Combining both is possible at low doses but additive sedation requires caution.

CBN is a THC degradation product with weak CB1 activity (~25% of THC). 1975 study found CBN + THC combination more sedating than THC alone — the basis for CBN's sleep reputation. Alone at moderate doses: mild relaxation, not strong sedation. Combined with CBD or delta-8: more reliably sleep-promoting. Stack with melatonin for both circadian and sedative sleep support.

Kratom's energy effect comes from mitragynine's adrenergic activation at low doses (2–4g). 2019 survey: energy was a top-3 reason for kratom use. Best strains: White Maeng Da (strongest energy), White Borneo (milder, longer), Green Maeng Da (energy + anxiolytic balance). Duration: 2–4 hours peak. Smoother and less anxious than caffeine, but builds tolerance faster.

CBD vs kanna for anxiety: CBD better for generalized daily anxiety management (79% response in 2019 study, broad safety record at 25–175mg). Kanna better for social anxiety specifically (2014 RCT directly reduced amygdala threat-response). Both are non-intoxicating. Combinable safely. Neither should be combined with SSRIs/MAOIs (kanna's serotonin reuptake inhibition creates interaction risk).

A hemp COA (certificate of analysis) should include: cannabinoid potency panel, pesticide panel, heavy metals panel, residual solvents. Must be from an ISO 17025-accredited third-party lab (not brand in-house) and batch-specific (matching the lot number on your product). 2022 analysis found widespread label inaccuracy — COA verification is the primary quality check in the unregulated hemp market.

Green vein kratom is balanced between white (stimulant-dominant) and red (sedative-dominant) — best for social situations, moderate daytime anxiety, mild pain during active hours, and beginners. Effect at 2–4g: mild energy, mood lift, reduced anxiety. At 4–7g: shifts toward anxiolytic/mild sedation while maintaining more alertness than red vein. Green Maeng Da most popular; Green Malay longest duration.

Red vein kratom has the highest 7-OH/mitragynine ratio due to extended drying — most sedating, analgesic, and opioid-receptor-active type. Best for: pain management, sleep (4–7g), muscle relaxation, evening anxiety. Not for daytime/functional use. 2019 survey: pain management was kratom's top reported use case. Red Bali (most available) and Red Maeng Da (most potent) are top strains.
