San Diego banned kratom in 2016 over concerns that its active compounds behave like opioids, carrying risks of addiction, abuse, and death. The city was one of the first jurisdictions in California to act, and the ban remains in effect today. Since then, the legal landscape has shifted dramatically: California now prohibits the sale and manufacture of kratom products statewide, making the local ban part of a much broader restriction.
What San Diego’s 2016 Ban Covers
The City of San Diego passed an ordinance in 2016 that banned the manufacturing, sale, distribution, and possession of kratom, grouping it with other novel synthetic and psychoactive drugs. City officials cited the threat these substances pose to public health and welfare, and the law took effect immediately rather than going through a delayed implementation period.
The ban applies within San Diego city limits. San Diego County’s Board of Supervisors later took a separate step, declaring kratom a public nuisance in unincorporated areas of the county. Other cities within the county, like Oceanside or Chula Vista, were not automatically covered by San Diego’s city ordinance, though the statewide prohibition that followed has since closed those gaps.
The Health Concerns Behind the Decision
The primary justification was kratom’s opioid-like properties. Kratom contains mitragynine, a compound that acts on the same brain receptors as opioid painkillers. Officials pointed to data suggesting this exposes users to the risks of addiction, abuse, and physical dependence, similar to the risks associated with prescription opioids.
Local death statistics played a significant role. The San Diego County Medical Examiner’s office reported that mitragynine was associated with 10 deaths between 2014 and 2018. While “associated with” doesn’t necessarily mean kratom was the sole cause in each case (many kratom-related deaths involve other substances), the figures gave lawmakers concrete local evidence to justify action. County supervisors explicitly cited these numbers when declaring kratom a public nuisance.
Compliance Has Been a Problem
Despite the ban, enforcement proved difficult. A study published in Preventive Medicine Reports examined vape and smoke shops within the City of San Diego and found that 46% of the shops surveyed were still selling kratom in violation of the local ordinance. Out of 26 shops checked, 12 had kratom available on their shelves. This high rate of noncompliance suggested the city-level ban alone wasn’t enough to keep kratom out of local stores.
California’s Statewide Ban Changed Everything
The local debate became somewhat secondary when California enacted a statewide prohibition on kratom and 7-hydroxymitragynine (a more potent compound derived from kratom). Under current state law, it is illegal to manufacture or sell kratom products for consumption at any age anywhere in California. This isn’t an age restriction or a labeling requirement. It is a full ban.
Governor Newsom’s office reported in March 2026 that full enforcement began on February 9, with agents conducting over 4,500 visits to licensed businesses. The state announced 95% compliance, with 3,308 illicit kratom and 7-OH products removed from store shelves. Businesses that fail to comply face administrative action, including suspension or revocation of their alcohol and beverage licenses.
For anyone in San Diego, this means kratom is now prohibited at every level of government: city, county, and state. Even if the local ordinance were repealed tomorrow, the statewide law would still make kratom illegal to buy or sell.
What This Means If You’re in San Diego
You cannot legally purchase kratom at any retail location in San Diego, and businesses caught selling it risk losing their state licenses. The statewide ban covers dietary supplements, food products, and anything marketed for consumption that contains kratom or 7-OH. Online purchases shipped into California fall under the same restrictions.
If you’ve been using kratom for pain management or to manage opioid withdrawal, the ban doesn’t come with a medical exemption. Kratom is not classified as a controlled substance at the federal level, but California’s prohibition treats it as an illegal product regardless of federal scheduling. The practical reality is that San Diego was ahead of the curve in 2016, and the rest of California has since caught up.
