San Mateo County Becomes First Bay Area Jurisdiction to Ban Kratom and 7-OH Products

Why it matters

San Mateo County's decision to ban kratom and 7-OH products sets a precedent for Bay Area regulation of largely uncontrolled substances linked to addiction and overdose deaths. This local action addresses a regulatory vacuum while state legislation moves slowly.

The big picture

Kratom has shifted from traditional leaf products to high-potency concentrated extracts, particularly 7-hydroxymitragynine (7-OH), which acts as a potent opioid with up to 22 times greater receptor affinity than morphine. California has documented 27 kratom-related deaths from 2020-2022. San Mateo County's ban applies to both traditional leaf and synthetic products, though some advocates argue for differentiation between natural and concentrate forms.

Key findings

• San Mateo County supervisors voted 5-0 to ban all kratom and 7-OH products in unincorporated areas
• Violations are treated as misdemeanors with fines up to $1,000 and six months jail
• Retailers face permit and license revocation
• Products are widely sold in smoke shops, gas stations, and online despite FDA warnings
• 27 documented kratom-related deaths in California 2020-2022

What they say

Supervisor Ray Mueller: "People are going in to stores and really finding an opioid that is readily present, available and being marketed and, in many cases, being marketed to youth." Dr. Kismet Baldwin-Santana, San Mateo County Health Officer: "There are known health risks due to kratom and its alkaloid derivatives, including overdoses, deaths and other adverse effects."

Bottom line

**San Mateo County's comprehensive ban reflects growing consensus that unregulated kratom, especially concentrated forms, poses unacceptable public health risks requiring local intervention when state action stalls.**
