Early Historical Use of Cannabis
The first medicinal use is
recorded in a Chinese
document from the first 2
centuries AD, states passed
down from Emperor
Shen Nuang in the 3rd
millenium BC

Hildegard of Bingen (1098-1179)
Hildegard was the first major German mystic; a proliferative writer,
philosopher, prophet, poet, dramatist and physician. From age 6
began having visions, which she said came straight from God. Her
visions were pivotal in directing her to a life of mysticism.
From Physica-“Whoever has an empty brain and head pains may eat
it [cannabis] and the head pains will be reduced”
Introducing Cannabis into Western Medicine


Dr. O'Shaughnessy's 1839 paper caused a
sensation when it became widely
available in England. Physicians
throughout Europe and America tried
cannabis for a huge variety of illnesses.
Also introduced electrolyte
replacement for cholera and the
introduction of the telegraph to India
for which he was knighted by Queen
Victoria

Medical and Physical Society of Bengal, 8, 1838-40, 421-461. Reprinted in Mikuriya, 1973, 3-30.

First Cannabis use for Chronic Daily
Headache!
 “The headache to which I wish


to draw attention is of a dull,
continuous or subcontinuous
character, attended sometimes
with paroxysmal exacerbations”
“..may last weeks, months or
even years”
Describes a regimen of
increasing doses of cannabis,
twice daily.

students (white) smoking
[marijuana] and getting
sympathy with stories of racial
persecution. Result

Several reports note temporal

May also precipitate MI in those with
CAD
After MI, mortality rate significantly
higher in marijuana users
Enhances sympathetic tone
Marijuana increases heart rate and
blood pressure

Marijuana and Brain Abnormalities?
40 people aged 18-25 years. Half
used marijuana at least once
weekly (starting 14-18 years old),
other half did not use.
For marijuana users, found
greater density values in the
nucleus accumbens and
amygdala.

Limitations



No measures of cognitive performance or any other
behaviors. Impossible to interpret meaning of any
brain measure differences
Marijuana group used multiple other substances;
impossible to disentangle the effects of marijuana
form those of other drugs
Association is not causation! Authors repeatedly and
explicitly state a causative relationship between
marijuana use and anatomic changes, only to state 2nd
last paragraph no causative relationship can be
concluded due to the cross-sectional design!
Impediments to Cannabis Research


National Institute of Drug Abuse (NIDA) the sole
source of research grade cannabis for all US trials
NIDA contracts only with University of Mississippi
to grow the cannabis-dependent on their strains
DEA registration for a schedule 1 substance
IND application on file with the FDA
Privately funded marijuana studies must go through
Public Health Service review in addition to FDA—
an extra step that does not exist for research
concerning any other drug. That review is mandated
by the Department of Health and Human Services,
not DEA. REMOVED JUNE 2015
In the last year the Federal Government has
increased production from 46 pounds to 1400
pounds to ensure product for future trials!

Whiting PF et al. Cannabinoids for Medical Use. A Systematic Review and Meta-analysis. JAMA 2015;313:2456-2473
Conclusions
Moderate-quality evidence to
support the use of cannabinoids
for the treatment of chronic pain
and spasticity.
There was low-quality evidence associated with improvements in
nausea and vomiting due to
chemotherapy, weight gain in HIV
infection, sleep disorders, and
Tourette syndrome.

May offer oral cannabis extract (OCE)
for MS related symptoms of spasticity
and pain (excluding central neuropathic
pain) Level A and THC (Level B)
OCE probably ineffective for improving
objective spasticity measured (short
term) or tremor (Level B)
Might offer Sativex oromucosal
cannabinoid spray to reduce symptoms
of spasticity, pain and urinary frequency
(Level B)

Cannabinoids in Epilepsy


Despite >20 anti-seizure meds, 30% of people with
epilepsy still have seizures

endocannabinoid system in those with epilepsy
(lower levels of CSF anandamide)

Historically only 4 placebo-controlled studies
using cannabinoids and epilepsy- problems with
methodology, poor power and lack of blinding
Cannabidiol (CBD) -anti-seizure- independent of
endocannabinoid system
THC and synthetic THCs can provoke seizures

for headache

Experimental evidence with
Cannabinoids & Headache
Goadsby et al demonstrated
that an endogenous
cannabinoid receptor ligandanandamide was able to
inhibit dural blood vessel
dilation from electrical stim,
CGRP, nitrous oxide and
capsaicin and this was reversed
by a cannabinoid antagonist

Cannabinoid Receptor Evolution
Cannabinoid Receptor Evolution
Cannabinoid receptors occur
throughout the vertebrates- hence are
evolutionarily ancient.
Genes for such a receptor were found
in the deuterostomian invertebrate
Ciona intestinalis, but not in
protostomian invertebrates (e.g.
Drosophila).
Ciona intestinalis
(transparent sea squirt)
Likely that cannabinoid receptors
developed first in deuterostomian
invertebrates
Hallucinogens and Headache
The Beginings of Hallucinogen use
for Cluster Headache
Psilocybin cubensis growing in manure. Yum!
In 1998 a 35 year old
Scottish man wrote on
clusterheadache.com. He
had episodic cluster for
many years. One year he
skipped his fall cycle and the
only thing different was
recreational use of LSD
during summer and this
started to be discussed
Personal communication, Bob Wold, cluster headache sufferer and founder of a cluster headache website
Psilocybin or LSD for Cluster Headache
Survey of cluster headache (CH) patients who use one of these
agents as an abortive and to induce a remission.
21/53-chronic CH and 10/20 who used psilocybin reported a
complete cessation of attacks
2 chronic CH pts used LSD, at sub-hallucinogenic doses, both
stopped attacks

Legal Issues with Psilocybin Mushrooms
Possession of psilocybin
containing mushrooms is
illegal (Schedule 1).
What can happen!
Spores do not contain
psilocybin and are not
illegal in most US states.
Spores are illegal in CA,
Georgia and Idaho.
LSD and Migraine

Otto snow outlines his use of LSD
(pub. 2003) to treat migraine
attacks and with periodic use keep
attacks away.
He references Ling & Buckman
(1963) who detail the clinical use of
LSD for cases of anxiety, frigidity,
migraine, psoriasis, etc., based on
their treatment of over 350 patients
at Marlborough Day Hospital (in
London).

Doctor-Patient Communication and First
Amendment Rights



California- medical marijuana in 1996. After DEA threats,
physicians brought suit to prohibit the Government from
taking action against them for communicating with patients
about the medical use of marijuana.
Trial court-DEA action only permissible if Feds had substantial
evidence that the physician ‘aided and abetted the purchase,
cultivation, or possession of marijuana’.
In 2002- 9th Circuit Court of Appeals affirmed the injunction,
ruling that First Amendment prohibits the government from
punishing physicians “on the basis of the content [potential
usefulness of marijuana] of doctor-patient communications.
Little doubt the US Supreme Court would follow it today
