The Mayo Clinic calls it addictive, unsafe and ineffective. Opponents call it “gas station heroin.” But for Patti Wheeler, it’s the tragic cause of death for her 27-year-old son Robert “Wyatt” Wheeler, who suffered a fatal seizure just six weeks after he began taking Kratom. With the U.S. Drug Enforcement Administration announcing July 1 that it is implementing a temporary, emergency ban on synthetic, concentrated forms of the drug — a compound called 7-hydroxymitragynine (7-OH) — we talk to Wheeler about her years of advocacy work and why she believes the ban needs to be broader and permanent. We also speak to a local recovery expert about the unique threats and challenges posed by ever-evolving formulas of synthetic drugs.
