Thanks to
legalization advocates, an issue mostly confined to scholarly and legal debates
-- that of the scheduling of drugs as laid out in the Controlled Substances Act
(CSA) -- has recently gained prominence.
I address this
at length in a recent Law Review article I wrote called "Much Ado About Nothing."
In short, the
reason marijuana hasn't been rescheduled is because no product of whole, raw
marijuana has a "currently accepted medical use" in the U.S., which
is part of the legal definition of Schedule I defined by the Controlled
Substances Act.
By contrast,
Schedule II substances have a currently accepted medical use in the U.S. or a
currently accepted medical use with severe restrictions (and, like Schedule I
drugs, a high potential for abuse).
More
importantly, regardless of the schedule, any substance may be prescribed by
physicians and dispensed by pharmacists only when incorporated into specific
FDA-approved products.
That is why
Schedule II opioid products can be obtained in pharmacies by prescription, but
raw opium, despite being in Schedule II, cannot be prescribed.
This fact is
sometimes articulated as follows: "Schedule II substances may be
prescribed."
This
abbreviated description, however, is incomplete and has caused significant
confusion. "An approved product comprised of a Schedule II substance may be prescribed" or even "An approved product based on ingredients found in Schedule I substances can be prescribed" would be accurate statements.
So why doesn't whole marijuana have a "currently accepted medical use"?
Well, there
have not been scientific studies, of adequate size and duration, showing that a
product comprised of raw, whole marijuana (smoked or vaporized or otherwise
ingested) has medicinal value.
FDA has never approved crude plant materials as
a prescription medicine, partly because there is no way to administer it in
defined doses and without any toxic by-products.
However, there
have been studies showing that components or constituents within marijuana have
medical value.
This is where
many people get confused.
That is why
both statements "marijuana has no medical value" and "marijuana
is a medicine" are both untrue.Which components within marijuana have accepted medicinal value?
At least one,
and maybe even more than that.
Right now, a
capsule, Marinol, entirely containing lab-made THC, the active ingredient in
marijuana (e.g. what gets you high) is in Schedule III and widely available
(though not often prescribed) at pharmacies.
Marinol was
approved first for nausea/vomiting from cancer chemotherapy and again during
the height of the AIDS epidemic, specifically for people who could not eat
(scientists have long known that THC boosts appetite).
THC has also
been tested (but not yet approved) as an analgesic - meaning it helps lessen
severe pain (like the pain associated with cancer).
But we know
that THC isn't the only interesting component in marijuana.
Recently
scientists have discovered that CBD (Cannabidiol) has powerful anti-seizure and
other therapeutic properties.
CBD does not
get you high and barely exists in the modern marijuana found on the street
today.
Some US
state-sanctioned medical dispensaries do contain expensive, specially grown
strains of smoked/ingested/extracted (in an oil, for example) marijuana with
very high levels of CBD (and low levels of THC - not enough to get you high).
These products
have not been properly tested and standardized, however.
So what about
CBD as a product?
Almost
two-dozen countries have approved a product comprised of an extract of
marijuana that mainly contains CBD and THC called Sativex.
Sativex is an
oral spray that does not get you high, and has been shown to have positive
effects on spasticity associated with MS and severe cancer pain.
Sativex is
currently in late-stage Phase III trials with the FDA.
So where does
that leave us?
While raw
marijuana does not meet criteria for a Schedule II drug, that doesn't mean we
can't harness the medicinal value contained within it.
We do this with
several drugs today, including a drug like GHB (a powerful Schedule I drug
associated with date-rape).
A product
called Xyrem is not Schedule I and is based on the active ingredient
in GHB, prescribed for narcolepsy and loss of muscle control.
The issue of
"scheduling" is distracting and essentially meaningless, since the
differences between Schedules I and II are mainly technical.
That is why
rescheduling marijuana would mainly serve as a symbolic victory for marijuana
advocates - since it would do nothing to change marijuana's non-placement in
the pharmacopeia or even decrease marijuana-specific penalties for use or
trafficking.
Marijuana's
components have medicinal value, though, like the Institute of Medicine (IOM)
concluded in the most sweeping independent review of this issue, its future as
a medicine does not lie in its smoked or ingested raw form.
Rather than
promote a non-accountable system of "dispensaries" run by non-medical
staff with ties to the underground economy and who sell marijuana to anyone
with a pulse, groups like Project SAM (Smart Approaches to Marijuana) are
trying to work with federal and state agencies to ensure we can study
marijuana's medicinal value and develop pharmacy-obtainable medications that
are safe and effective, with reliable dosage and known composition.
In the meantime
we could even enroll the seriously ill into research programs, as long as they
understand potential risks, so they can get these promising products today
(including children with uncontrollable seizures).
Don't the
seriously ill deserve at least that much?
