The American Herbal Pharmacopoeia (AHP) released in December 2013 a formal
quality standards monograph for cannabis (Cannabis
spp.), the first such document to be published in more than 70 years.1
Although the herb’s reputation in the United States was tarnished by 20th
century propaganda campaigns and further vilified by President Nixon’s “War on
Drugs,” 20 states and the District of Columbia currently recognize and approve
the medicinal use of cannabis.2 Emerging data on the plant’s potential
medicinal effects, requests from consumer advocacy groups and regulators in
states seeking testing standards guidance, and evolving public attitudes
prompted AHP to develop the monograph in an effort to ensure a consistent and
quality product for informed patients.
“Due to the increasing approval of the medicinal use of cannabis by states,
there was an apparent shift in social policy as the cannabis conversation
became more mainstream, not in the ‘demon pot’ way of the 1970s, but with a
focus on potential medicinal use,” said Roy Upton, executive director of AHP and lead author of
the monograph (email, December 19, 2013). “With states approving medical use and many cannabis
advocates espousing innumerable potential benefits, it became clear the states
needed guidance on quality control, and consumers and health professionals
needed accurate information on efficacy and safety.”
The document is AHP’s 35th herb monograph, each of which is designed to provide
“standards of identity, purity, analysis, and quality, as well as information
on the cultivation and storage of the botanical and its preparations.”1
Spanning more than 60 pages, the cannabis monograph is divided into five main
sections: Nomenclature, Identification, Commercial Sources and Handling,
Constituents, and Analytical. The extensively referenced document
contains high-quality cannabis photographs for identification purposes,
information on potential contaminants or adulterants, and detailed descriptions
of the plant’s main chemical constituents.3
AHP’s standards monograph for cannabis will be followed by the publication of a
therapeutic compendium in mid-2014. According to AHP’s Cannabis Monograph Q&A, the
compendium will include “historical and traditional herbal medicine
[information] along with a review of modern scientific literature encompassing
indications, contraindications, side effects, dosing, preparations, safety, use
in pregnancy, and interactions with conventional medications.”4In development since 2011, the cannabis standards monograph was written,
edited, and reviewed by internationally renowned experts in analytical
chemistry, botanical nomenclature and identification, and law, among others.
AHP also received support and guidance from the medicinal cannabis patient
advocacy organization Americans for Safe Access (ASA) and researchers from the
University of Mississippi, home to the only federally approved cannabis
research program in the United States.5
During a time when consumers can purchase state-legal cannabis at dispensaries
for medicinal use — and in Colorado and Washington State for recreational use —
analytical and quality standards are essential to ensuring a safe and
consistent product.“[D]ifferent analysts are using different technologies and methods and
reporting their results, such as quantitation of THC [tetrahydrocannabinol, the
primary psychoactive compound in cannabis], in different ways that are often
not scientifically valid. They then use those analytical results to claim some
level of superiority, such as higher THC values, which dispensaries and
patients or product manufacturers use to influence buying decisions,” stated
AHP in its Cannabis Monograph Q&A.4 “Adherence to a monograph
standard ensures that results are consistent and findings are accurate.”
Despite its recent release date, the pioneering document already has been
incorporated into state cannabis laws. “The AHP cannabis
monograph was written into regulatory statute in Washington as a way to guide
labs in the appropriate testing of cannabis,” said Upton. Backers
of AHP’s monograph — and the forthcoming therapeutic compendium — hope that the
documents will have a direct and positive impact on the public, from patients
and consumers to physicians and lawmakers.
Upton, who maintains that AHP’s monograph is not “pro-cannabis” but rather
“pro-quality,” believes that disseminating impartial, scientific literature-supported
information to the public will help guide the cannabis debate in the United
States.
“[I]t is a starting place to have a rational conversation of what is real and
what is misconception on both the advocacy and opposition fronts,” said Upton.
“It is clear the conversation, and the monograph, will continue to evolve.”
