From South Dakota bans to Arizona dispensaries, hemp-THC products are reshaping the fight for regulated MMJ markets.
The National Collision Between Hemp and Marijuana
Across the country, hemp-derived THC products are testing the limits of cannabis regulation. Gummies, drinks, and vapes containing delta-8, delta-10, HHC, and THC-O are sold openly in vape shops and convenience stores, their legality derived from a quirk in the 2018 Farm Bill that legalized hemp with less than 0.3 percent delta-9 THC. Chemists quickly learned how to synthesize intoxicants from hemp’s CBD, and an unregulated market worth billions emerged almost overnight.
For state-licensed cannabis businesses, the challenge is existential. While medical marijuana and adult-use programs require strict compliance—from lab testing to seed-to-sale tracking—hemp-THC products often face no such rules. Consumers can buy them without prescriptions, cards, or taxes, often at a lower cost. This dynamic pits heavily regulated dispensaries against hemp shops operating in a legal gray zone.
Several states have responded with bans or restrictions. Hawaii, Massachusetts, and Mississippi have prohibited the sale of intoxicating hemp products. Minnesota and Tennessee took a different approach, implementing rules on age, packaging, and lab verification. Yet at the federal level, Congress remains gridlocked, leaving the issue to play out state by state.
South Dakota’s $66 Million Test Case
In South Dakota, the stakes are especially sharp. The state’s medical marijuana program is projected to generate $66 million this year, but operators say unregulated hemp products are cutting into their patient base. Lawmakers attempted to plug the loophole with House Bill 1125 in 2024, banning the sale—but not the possession—of hemp-derived intoxicants like delta-8, delta-10, HHC, and THC-O.
Enforcement has followed, if unevenly. The Pennington County Sheriff’s Office staged sting operations in Rapid City, buying gummies and THC drinks from retail outlets. Sioux Falls police conducted compliance checks and now await lab results. In June, Rapid City police sent “courtesy letters” to 32 shop owners reminding them of the law before conducting random checks.
Violations carry Class 2 misdemeanors—up to 30 days in jail or a $500 fine per offense. For an industry with cash on hand and steady demand, these penalties may not be a strong deterrent. Yet the cannabis lobby, led by Jeremiah Murphy of the Cannabis Industry Association of South Dakota, is cheering the crackdown. Murphy represents 116 licensed MMJ businesses, and he argues that patients are abandoning the regulated system because unlicensed shops offer the same products with fewer hurdles.
As Murphy put it during a Medical Marijuana Oversight Committee meeting: “Why do I go to a doctor and pay him, and why go pay the state to pay even more money, when I can go to the vape shop, or I can go to the hemp store and they’re selling exactly what I need?”
Legal Uncertainty Shadows Enforcement
Despite the new law, South Dakota’s enforcement faces bottlenecks. Only the state health lab tests for chemical alterations, slowing down prosecutions. Retailers gamble that by the time products are tested, their shelves will already be restocked. Meanwhile, at least one company—Hemp Quarters 605—has sued the state in federal court, arguing the ban interferes with interstate commerce. A judge denied their injunction request, but the case continues.
The result is a patchwork enforcement climate: licensed MMJ operators fight for survival, police juggle testing delays, and hemp sellers keep pushing the envelope.
Where Arizona Fits Into the National Debate
For Arizona, the South Dakota battle isn’t just a distant policy fight—it’s a warning sign. Since legalizing adult-use cannabis in 2020, Arizona has built a billion-dollar cannabis market underpinned by testing, child-safe packaging, and tax revenue that feeds into public health and education funds.
Yet hemp-derived intoxicants circulate in Arizona as well, often sold at vape shops, gas stations, or through online delivery. The Arizona Department of Agriculture oversees hemp cultivation, but enforcement against intoxicating derivatives has been limited. Unlike South Dakota, Arizona has not banned the sale of delta-8 or related products, leaving them widely accessible.
For licensed dispensaries that invested heavily in compliance, this is déjà vu. Arizona operators echo the same concerns voiced in South Dakota: hemp shops sell intoxicating products without meeting the same standards, creating an uneven playing field. The cost difference can be significant. A patient who skips the dispensary avoids card fees, taxes, and the doctor visit, opting instead for a cheap hemp gummy from a corner store.
Regulators in Arizona have mostly leaned on consumer education, warning that hemp-derived THC products are not tested for safety, potency, or contaminants in the way dispensary products are. But dispensary owners say warnings aren’t enough. Without enforcement, hemp shops will continue to undercut the system.
A Tale of Two States, One National Problem
South Dakota’s aggressive ban contrasts sharply with Arizona’s laissez-faire approach, but both illustrate the same underlying conflict: how do regulated cannabis markets compete with unregulated hemp intoxicants? South Dakota has chosen enforcement. Arizona, at least for now, is watching and waiting.
The question for Arizona is whether waiting too long could erode public trust in the regulated system. If hemp products continue to capture market share, dispensaries that invested in legal compliance may find themselves squeezed out by an industry that plays by fewer rules.
Looking Ahead
The outcome of South Dakota’s enforcement efforts—and the lawsuits challenging them—will ripple far beyond its borders. If bans withstand legal scrutiny, more states may follow. If courts strike them down, hemp products could flood markets even more aggressively.
For Arizona, this national fight is not theoretical. The state’s cannabis program depends on balancing accessibility, safety, and economic sustainability. Whether Arizona regulators tighten oversight or let the hemp market expand unchecked may determine how resilient its billion-dollar industry remains in the years ahead.
