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 Emperor Shen Nuang (2838-2698 B.C.)

Bot. 1974;28:437-448 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 W. B.

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.

[Epub ahead of print] 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 Sewell RA, Halpern JH, Pope HG.

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 Thoth Press 2003 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).

Not in USA but may be illegal via banned analogue 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.
