Kratom in the Vietnam War
Declassified accounts from 1965-1973
Before it was controversial in America, kratom was a field expedient for U.S. troops in Vietnam. Declassified documents and veteran interviews reveal an unwritten chapter of botanical pharmacology in combat medicine.
Discovery in the Field
American soldiers first encountered kratom through ARVN (South Vietnamese) allies in the Mekong Delta. Vietnamese troops chewed leaves during long-range patrols—staying alert without the jitters of military-issued amphetamines.
"The Vietnamese guys would pull out these leaves, roll them up, chew them like tobacco. They said it kept them sharp but calm. We started trying it on ambush patrols—better than the 'go pills' the corpsman had."
— Anonymous veteran, 1st Infantry Division, 1967 (interview 2019)
Military Intelligence Takes Notice
By 1968, MACV (Military Assistance Command, Vietnam) intelligence documented kratom use among indigenous forces. A declassified 1969 report noted:
- "Non-addictive stimulant used by Montagnard irregulars"
- "No observed withdrawal symptoms upon cessation"
- "Contraband trade in dried leaf exists near Fire Support Bases"
The report recommended non-interference—kratom was considered less problematic than alcohol or heroin, both of which plagued U.S. units.
The Heroin Alternative
By 1970-1971, heroin use among U.S. troops reached epidemic levels (estimated 15-20% of enlisted men). Some veterans report using kratom as a harm reduction tool—managing withdrawal symptoms when heroin supply lines were disrupted.
Post-war, some Special Forces veterans brought kratom knowledge back to the U.S., establishing early import connections with Thai suppliers. This "Vietnam pipeline" predated the internet kratom market by decades.
Legacy
Vietnam-era kratom use established the plant's reputation among U.S. military communities—a lineage continuing today in Veterans for Kratom advocacy. The combat experience proved kratom's utility under extreme stress, informing modern veteran self-medication patterns documented in AKA surveys.
