Episode notes
Dose Determines Kratom's Effects
- Kratom produces stimulant effects at low doses and opioid-like effects at high doses due to different receptor activity.
- This dose-dependent duality explains why users report wildly different experiences with the same plant.
Gym Anecdote Of Opioid Replacement
- Nick met a gym member who switched from prescription opioids to kratom for chronic back pain.
- The man appeared functional and consistent at the gym, suggesting kratom helped him stay alive and active.
Why Kratom Feels Like Coffee And Opioids
- Mitragynine and 7-hydroxymitragynine are Kratom's main alkaloids and act on opioid and adrenergic receptors.
- Partial opioid activation gives pain relief and drowsiness with less respiratory depression than full opioids.
