CANNABIS DOSING AND TITRATION RECOMMENDATIONS
Children, Elders, and Cannabis, CBD and other cannabinoids
Primer for parents and other caregivers
NOTE: this is a work-in-progress. While written with my series of over 40 children with
seizure disorder and/or autism in mind, children are part of a larger group of
patients: the cannabis-naïve, those new to using cannabis, and the
medically-naive, (those who have used cannabis in the past, but now want to see
whether cannabis can help some illness or symptom that they have since
developed.
In
that vein, I will be editing these guidelines based on more experience,
feedback from patients, caregivers, and other practitioners, and further
advances in research and medicine
CBD dosing guidelines
DrFrank's CBD dosing guidelines:
I recommend starting at 0.5 mg/pound of body
weight/day into 2 or 3 doses each day, and gradually increasing up to 5
mg/pound/day.
NOTE: 5 mg/pound would be a very large dose for
THC, in my opinion.
But these numbers assume mostly CBD, with very
low THC levels.
The main side effects to monitor, while
increasing dose, are intoxication, sedation, tachycardia, and dysphoria
(opposite of euphoria). Fortunately, cannabis has an extremely good safety
profile, with no recorded deaths from overdose.
So when assessing the benefits versus risks, we
might exceed the “theoretical maximum” of 5 mg/pound/day, and go higher as
needed, and as tolerated.
Background info:
I have based my guidelines above on the
following 2 sources:
--Dr. Bonni Goldstein, pediatric emergency
physician and cannabis expert, who shared her experience at our quarterly
meeting of the Society of Cannabis Clinicians in September 2014, and
--GW Pharmaceuticals, who is supplying the
CBD-only tincture, Epidiolex, for it’s study on children with certain seizure
disorders.
Dr. Bonni Goldstein’s dosing::
0.5 mg/pound/day in 3 doses
increase 0.5 mg/pound/day at weekly intervals,
up to 2-6 mg/pound/day.
GW Pharmaceutical's Epidiolex:
5 mg/kilogram body weight/day divided in 2
doses (NOTE that this dosing is in KILOGRAMS (kg) of body weight, rather than
POUNDS.
When titrating, it’s Important to know:
Child’s weight
Actual MILLIGRAMS/dose of CBD, THC, and any
other cannabinoids (not just ratios), so we can evaluate what we might want to
increase or decrease, per volume of tincture or per piece of edible.
Caution/concern:
Some “CBD” sources are steering parents and
patients to other products containing significant amounts of other
cannabinoids, which may or may not be as useful, but add to the total
“cannabinoid load”, and can make it harder to titrate doses of CBD and THC, the
two cannabinoids we know the most about.
I feel it is important to see how optimal
dosing of CBD affects the patient’s symptoms or illness. I have concerns about adding too many
variables too soon, such as THC-A or CBG.
THC-A is “THC acid” which is the precursor of THC found in raw
cannabis. Apparently it is not
psychoactive, which may or may not be a good quality, but I am not sure how
pharmacologically active it is for seizure control
I believe that THC, and possibly also THC-A
also have their places, especially with some of the behavioral issues of
autism, which is a common co-factor in many of the seizure disorders I have
seen. But I recommend that until
you have titrated up to near the “theoretical maximum”* dose of CBD and
evaluated the effects, that you try to avoid adding other variables, such as
other cannabinoids.
DrFrank’s CBD info rap:
CBD vs. THC-Russo GW Tale of Two Cannabinoids
article
I'll try to simplify what I know.
THC is the more psychoactive of the many
cannabinoids in cannabis. There are over 70 identified, most in minuscule
amounts.
CBD is of low psycho-activity. I'm not sure I'd
say NO psycho-activity though, but much less than THC. I also think that
CBD-rich cannabis would cause less of the anxiety and/or paranoia that some
people experience with cannabis.
GW Pharmaceuticals is a company in the U.K.
that has extracted THC and CBD from the whole plant, and has been able to
market it in Europe and Canada as a 50:50 sublingual spray called Sativex.
It is NOT available in the U.S. at this time
Here is the url for the article by Ethan Russo
MD, and Geoffrey Guy MD of GW Pharmaceuticals:
A Tale of Two Cannabinoids
The therapeutic rationale for combining
tetrahydrocannabinol and cannabidiol
The salient sentence in the abstract is:
"CBD is demonstrated to antagonise some
undesirable effects of THC including intoxication, sedation and tachycardia,
while
contributing analgesic, anti-emetic, and
anti-carcinogenic properties in its own right."
