Federal Court Strikes Down Residency Requirement for Those Seeking State Marijuana Licensure

Augusta, ME: Federal court judges have ruled that a Maine law requiring licensed medical cannabis providers to be in-state residents is unconstitutional.

Judges for the US Court of Appeals for the First Circuit ruled 2 to 1 that the law was “facially protectionist” and thereby in violation of the Constitution’s dormant commerce clause – which seeks to discourage states from taking steps that excessively burden interstate commerce. The majority further determined that the medical cannabis industry is subject to the dormant commerce clause, even despite the federal prohibition of marijuana, because commercial activity in the marijuana market is routinely taking place absent any intervention from federal law enforcement.

They opined, “Congress’s enactment of the Rohrabacher-Farr Amendment in the wake of the CSA’s [Controlled Substances Act] passage … undermines the notion that no such interstate market exists. … [Further,] the prohibition that Maine’s Medical Marijuana Act seeks to impose on out-of-state actors entering that very market reflects the reality that the market continues to operate. That prohibition even indicates that the market is so robust that, absent the Medical Marijuana Act’s residency requirement, it would be likely to attract entrants far and wide.”

The majority concluded, “Why, then, would it be improper for us to apply the dormant Commerce Clause here? There is an interstate market, and a state is trying to protect its advantageous position with respect to it.”

The dissenting judge argued that the commerce clause’s protections ought to be applicable only to national markets involving goods or services that Congress has deemed legal.

Maine regulators had already dropped a similar residency requirement for those seeking licensure to participate in the adult-use market.

The case is Northeast Patients Group v. Maine Department of Administrative and Financial Services.

Analysis: Heavy Metals Frequently Identified in Unregulated CBD Products

Miami, FL: CBD-infused products commercially available in retail stores and online often contain heavy metals, such as lead, arsenic, and mercury, and typically contain less-than-advertised quantities of cannabidiol, according to data published in the journal The Science of the Total Environment.

Investigators affiliated with the University of Miami School of Medicine and with the Ellipse Analytics Testing Lab in Denver assessed 516 CBD products for cannabidiol content as well as for the presence of heavy metal contaminants. Of these products, 121 products were intended for oral consumption.

Consistent with prior analyses of unregulated CBD products, many contained impurities and inaccurate labeling.

Of the CBD-infused edible products analyzed, 42 percent tested positive for the presence of lead, 37 percent tested positive for mercury, 28 percent tested positive for arsenic, and eight percent tested positive for cadmium.

Over 40 percent of all of the products tested contained significant lower percentages of CBD than advertised on the products’ labeling. Among edible products only, 29 percent contained lower quantities of CBD than advertised.

“Low-level contamination of edible CBD products with heavy metals and phthalates is pervasive,” authors concluded. “There is substantial discrepancy between the product label claims for CBD potency and the amount measured in both edible and topical products, underscoring the need for tight regulations for CBD product label integrity to protect consumers.”

They added: “Given that the consumer demographic purchasing CBD products includes those afflicted with pain, insomnia, anxiety, and other health conditions, these findings could give consumers and medical practitioners hesitation about the benefits and potential harm of CBD use. If left unaddressed, these findings could lead to decline in consumer trust and public health concerns. CBD mistrust could lead to consumers and retailers abandoning this category of potentially efficacious medical therapies. … It is incumbent upon manufacturers to recognize the prevalence of misleading claims on labels, identify the sources of the discrepancies between label claims and measured CBD content, and improve label accuracy through a commitment to frequent and thorough independent testing procedures.”

Heavy metal contamination has also been identified in unregulated delta-8 THC vapor products.

More than three years following the passage of federal legislation legalizing hemp production, the US Food and Drug Administration (FDA) has yet to promulgate rules regulating the marketing and sale of commercial products containing hemp-derived CBD or other cannabinoids. Survey data compiled by the National Consumers League previously determined that more than eight in ten US voters desire greater federal regulatory oversight over the labeling and marketing of commercially available CBD products.

Survey: Cannabis Reportedly More Effective Than Prescription Anti-Emetics for Hyperemesis Gravidarum

Los Angeles, CA: Survey respondents who acknowledge having consumed cannabis to address symptoms of Hyperemesis Gravidarum (HG) frequently report that it is more effective than prescription medications at reducing severe nausea and vomiting.

A team of researchers affiliated with the University of California, Los Angeles and with the Hyperemesis Education and Research Foundation in Oregon surveyed 550 respondents who suffered from HG during their pregnancy. Among respondents, 96 percent acknowledged having used prescription anti-emetics; 14 percent reported having used cannabis. Most (71 percent) of those who acknowledged having consumed cannabis said that they did so because prescription medications inadequately managed their symptoms.

Of those who consumed cannabis, 82 percent reported HG symptom relief – a finding that is consistent with prior case reports and surveys. By comparison, only 60 percent reported obtaining relief from prescription anti-emetics. Moreover, among patients who reported experiencing weight loss during pregnancy, 56 percent of those who used cannabis reported gaining some or all of it back within two weeks of treatment, compared to 25 percent of prescription drug users.

Authors concluded: “This study adds to growing literature supporting antiemetic properties of cannabis and cannabinoid compounds while also suggesting their potential to treat HG. … A minority of respondents in this survey reported using cannabis for HG; however, those who used cannabis or CBPs [cannabis-based products] reported more frequent relief from HG symptoms compared to those who used prescription antiemetics. Furthermore, those cannabis users were more likely to report weight gain within two weeks of treatment than those who used ondansetron, reportedly the most effective prescription antiemetic for survey respondents.

“Cannabis products may be perceived as a more effective alternative, but more research is required to understand its mechanism and safety… In the meantime, providers must weigh unknown risks of recommending cannabis… with the well-established risk of adverse maternal and fetal outcomes for refractory HG.”

Study: CBG Administration Lowers Blood Pressure in Preclinical Model

Hershey, PA: Mice injected with the cannabinoid CBG (cannabigerol) experience a significant decrease in mean blood pressure, according to preclinical data published in the journal Frontiers in Physiology.

A team of researchers with Penn State College of Medicine assessed the cardiovascular impact of CBG compared to placebo in healthy mice. Animals in the study were injected in the abdomen with either CBG or a saline solution.

Authors reported, “[A]cute CBG administration elicits a significant decrease in blood pressure in phenotypically normal male mice, without altering heart rate or locomotor activity.”

They concluded: “The present study provides new mechanistic insight into the cardiovascular effects of CBG in the context of normal blood pressure. … Overall, these findings add to the growing literature regarding the role of cannabinoids in blood pressure regulation. Additional research on CBG is needed to define the precise molecular mechanisms and sites of action, effects of more chronic administration, and potential for therapeutic use to lower blood pressure in models of hypertension.”

A 2017 clinical trial previously documented the ability of oral doses of CBD to lower blood pressure in healthy volunteers, while a 2021 observational trial identified a link between long-term cannabis use and a reduction in systolic and diastolic blood pressure in elderly subjects.

Cannabinoids have long been known to influence cardiovascular function, though data regarding their effects has been conflicting. According to the results of a 2021 literature review of 67 studies published in the American Journal of Medicine, “[M]arijuana itself does not appear to be independently associated with excessive cardiovascular risk factors,” although authors did caution that “it can be associated with other unhealthy behaviors such as alcohol use and tobacco smoking that can be detrimental” to cardiovascular health.

Data assessing neonatal outcomes among children with in utero exposure to cannabinoids is inconsistent, with some studies highlighting potential links with pre-term birth and lower birth weight and other studies finding no such associations.
