Rob Clarke and Mark Merlin are pleased to announce the upcoming publication of Cannabis: Evolution and Ethnobotany by University of California Press
September 1, 2013.
Cannabis: Evolution and Ethnobotany is a comprehensive, interdisciplinary exploration of the natural origins and early evolution of this famous plant, highlighting its historic role in the development of human societies. The plant Cannabis has long been prized for the strong and durable fiber in its stalks, its edible and oil-rich seeds, and the psychoactive and medicinal compounds produced by its female flowers. The culturally valuable and often irreplaceable goods derived from Cannabis deeply influenced the commercial, medical, ritual, and religious practices of human cultures throughout the ages, and desire for these commodities directed the evolution of the plant toward its contemporary varieties. As interest in Cannabis grows and public debate over its many uses rises, this book will help us understand why humanity continues to rely on this plant and adapts it to suit our needs.
Robert C. Clarke is a Cannabis Researcher, Projects Manager for the International Hemp Association in Amsterdam, and author ofMarijuana Botany and Hashish!.
Mark D. Merlin is a Botany Professor at University of Hawai’i at Mānoa, author of On the Trail of the Ancient Opium Poppy and co-author ofKava: The Pacific Drug.

ScienceDaily (May 15, 2008) — A variety of middle-class people are making a conscious but careful choice to use marijuana to enhance their leisure activities, a University of Alberta study shows.
A qualitative study of 41 Canadians surveyed in 2005-06 by U of A researchers showed that there is no such thing as a ‘typical’ marijuana user, but that people of all ages are selectively lighting up the drug as a
way to enhance activities ranging from watching television and playing sports to having sex, painting or writing.
“For some of the participants, marijuana enhanced their ability to relax by taking their minds off daily stresses and pressures. Others found it helpful in focusing on the activity at hand,” said Geraint Osborne, a professor of sociology at the University of Alberta’s Augustana Campus in Camrose, and one of the study’s authors.
The focus was on adult users who were employed, ranging in age from 21 to 61, including 25 men and 16 women from Alberta, Quebec, Ontario and Newfoundland whose use of the drug ranged from daily to once or twice a year. They were predominantly middle class and worked in the retail and service industries, in communications, as white-collar employees, or as health-care and social workers. As well, 68 per cent of the users held post-secondary degrees, while another 11 survey participants had earned their high school diplomas.
The study also found that the participants considered themselves responsible users of the drug, defined by moderate use in an appropriate social setting and not allowing it to cause harm to others.
The findings should open the way for further scientific exploration into widespread use of marijuana, and government policies should move towards decriminalization and eventual legalization of the drug, the study
“The Canadian government has never provided a valid reason for the criminalization of marijuana,” said Osborne. “This study indicates that people who use marijuana are no more a criminal threat to society than are alcohol and cigarette users. Legalization and government regulation of the drug would free up resources that could be devoted to tackling other crime, and could undermine organized crime networks that depend on marijuana, while generating taxes to fund drug education programs, which are more effective in reducing substance abuse,” Osborne added.
The study was published recently in the journal Substance Use and Misuse.

1. Gov. Romney wants to arrest medical marijuana patients
Last week, we encountered former Massachusetts Gov. Mitt Romney (R) for the third time. During our two previous encounters, Gov. Romney used our questions regarding medical marijuana as opportunities to discuss his overall opposition to drug legalization and to explain his plan for educating American youth about drug use. However, in regard to medical marijuana, he only said, “I will look at the issue … I will inform myself.”
Last week, during a July 25 town hall meeting in Bedford, when asked by an audience member about his thoughts on the war on drugs, he touched briefly on medical marijuana, saying, “People talk about medicinal marijuana. And you know, you hear that story that people who are sick need medicinal marijuana. But marijuana is the entry drug for people trying to get kids hooked on drugs. I don’t want medicinal marijuana; there are synthetic forms of marijuana that are available for people who need it for prescription. Don’t open the doorway to medicinal marijuana.”
After the event, GSMM volunteers, including a seriously ill patient in a wheelchair and a medical professional, approached Gov. Romney after the event to ask a follow-up question. After Gov. Romney ignored the patient’s repeated attempts to ask him a question, I asked him, “I was wondering why you don’t respect states’ rights when it concerns seriously ill patients who use medical marijuana in the 12 states that have approved its use. Why don’t you respect states’ rights in that situation, a life and death situation?” He responded, “Because synthetic marijuana is available by prescription. It’s very simple, very simple, very simple.”
When the medical professional with us introduced herself and explained to the governor that synthetic forms of marijuana are not effective for many patients, he disagreed, saying, “I have spoken with doctors and researchers, and the medical marijuana effort is an effort to try and legalize marijuana in this country, and it’s a mistake in my opinion to go in the direction of opening up the nation to medical marijuana … I am not in favor of medical marijuana. Other pain relievers are available in this country, and I support the use of those other pain relievers. And synthetic marijuana, with the elements that are essential, is available.”
2. Gov. Richardson won’t let federal raids continue on his watch!
New Mexico Gov. Bill Richardson (D) has been spending a lot of time campaigning in New Hampshire, and we always take the opportunity to thank him for his repeated pledges to end the federal raids on medical marijuana patients and for his support of medical marijuana legislation in his home state.
During our most recent encounter at a meet-and-greet in Concord, I him what he thought about the six Republican candidates who have said they would raid and arrest the sick and dying in medical marijuana states like New Mexico. Gov. Richardson responded with shock that anyone would want to arrest seriously ill people and said, “Don’t worry, if I’m elected that won’t happen. You know, there are people that are dying that just want their pain eased, and so they came to me in New Mexico, 199 human beings that said, look we just want it for medicinal reasons, to be able to use medical marijuana to ease our pain. And I said, ‘Okay, let’s find a way that there’s proper Department of Health safeguards that … we don’t have running rampant a bunch of gardens with you-know-what. Let’s do it right.’ And it’s working, it’s working. So we’ve got to do the right thing. That is the right thing.”

HEMP OIL AND PAINTING
Dutch masters used hemp oil in their paintings, but since then linseed oil has become much more common. When I heard this I tried using hemp oil in my own artwork, and brushed on a patch of each on to an oil primed canvas. (Which, as the name implies, was made of hemp – Cannabis sativa – but is now usually made from flax). After some months the linseed oil yellowed, but the hemp oil was clear.
Observing this, I turned to The Artist’s Handbook by Ralph Meyer, and this is what he had to say on the drying of oils:
“The drying properties of most oils are due to the presence of glycerides of linoleic and linolenic acids, which have the properties of combining spontaneously with atmospheric oxygen to start a chain of reactions which end in the conversion of the oil to the tough, durable film known as linoxyn. The action of the moisture on certain of the glycerides of linoleic acid, particuarly in the absence of daylight, is also one of the chief causes of the yellowing of oil films. Linseed oil has a larger percentage of linolenic acid and its glycerides than any other drying oil except perilla oil…compared with linseed oil, poppy oil containes a smaller total amount of these glylcerides, and little or no linolenic acid, and this minimizes one of the causes of yellowing of its films”.
p. 355, The Artist’s Handbook by Ralph Meyer, 1945 edition.
