Spectrum News Four-Part Kratom Investigation: From Leaf to Lab, What the Science Actually Shows

Why it matters

A national news organization launched a four-part investigative series on kratom the same week as the DEA's scheduling notices, providing one of the most comprehensive mainstream media examinations of the plant, its derivatives, and the competing claims about safety — reaching millions of cable subscribers.

The big picture

Kratom has been sold in U.S. gas stations for about a decade, but public understanding of what it actually is remains limited. Spectrum News assembled testimony from leading researchers, users, retailers, and addiction specialists to examine both the leaf's legitimate uses and the risks posed by concentrated 7-OH products. The series debuted as state-level bans and federal scheduling actions were reshaping the kratom market.

Key findings

• University of Florida medicinal chemistry professor Christopher McCurdy, considered the world's leading kratom expert, describes kratom leaf as having paradoxical dose-dependent effects -- stimulant at low doses, sedative at high doses
• Products labeled as kratom at gas stations and vape shops often contain concentrated 7-OH, which McCurdy calls 'pure opioid in its function' and more potent than morphine
• The DEA's 2016 attempt to schedule kratom was withdrawn after significant public and congressional backlash; use surged afterward
• Clemson University researcher Bryan Denham found people attempting to quit prescription painkillers are more likely to use kratom
• The four-part TV special 'Kratom: From Leaf to Lab' premiered on Spectrum News stations July 16, 2026

What they say

"However, it has this paradoxical effect where it gives you a stimulant and sort of endurance-like effect during the day at lower doses. And if you consume more of it, it can give you a more relaxing, sedative, sort of like alcohol or opioid, effect," — Christopher McCurdy, professor of medicinal chemistry, University of Florida

Bottom line

Spectrum News' four-part national investigation illustrates how mainstream media coverage of kratom shifted dramatically in July 2026, driven by federal scheduling action and growing state-level bans.
