Summary TheDrug.Wiki TripSit PsychonautWiki

Kratom (Mitragyna speciosa) is a tropical tree native to Southeast Asia with leaves containing indole alkaloids including mitragynine and 7-hydroxymitragynine. Effects are dose-dependent: low doses produce stimulant effects while higher doses produce opioid-like sedation and analgesia. Potency varies significantly between strains, batches, and vein colors (red, green, white, yellow).

Perspectives

“Kratom is a remarkable botanical, but if you are going to use it, dose sensibly and be careful not to make a habit of it.”

— Dominic Milton Trott, The Drug Users Bible 5 g oral
