“Three out of four doctors would prescribe marijuana to a patient who was experiencing pain from cancer, according to the results of a poll published in the New England Journal of Medicine.”
“The point of the vignette was to illustrate the kinds of patients that show up on our doorstep who need help. This issue is not one you can ignore, and some states have already taken matters into their own hands,” said Dr. J. Michael Bostwick, a professor of psychiatry at the Mayo Clinic in Rochester, Minn.
“There are no 100 percents in medicine. There’s a lot of anecdotal evidence that this is something we should study more. Forgive the pun, but there’s probably some fire where there’s smoke, and we should investigate the medicinal use of marijuana or its components,” Bostwick said.
Marijuana comes from the hemp plant Cannabis sativa. It’s a dry, shredded mix of the plant’s leaves, flowers, stems and seeds. It can be smoked as a cigarette or in a pipe, or it can be added to certain foods, such as brownies.”
“Marijuana (Cannabis sativa L.) is one of the first plants cultivated by man. Shrouded in controversy, the intriguing history of cannabis as a medication dates back thousands of years before the era of Christianity.
Scientists believe the hemp plant originated in Asia. In 2737 B.C., Emperor Shen Neng of China prescribed tea brewed from marijuana leaves as a remedy for muscle injuries, rheumatism, gout, malaria, and memory loss. During the Bronze Age in 1400 B.C., cannabis was used throughout the eastern Mediterranean to ease the pain of childbirth and menstrual maladies.
More than 800 years before the birth of Christ, hemp was extensively cultivated in India for both its fiber and healing medicinal properties. William Brooke O’Shaughnessy, an Irish physician famous for his investigative research in pharmacology, is credited with introducing the therapeutic, healing properties of cannabis to Western medicine. During the 1830’s Dr. O’Shaughnessy, working for the British in India, conducted extensive experiments on lab animals. Encouraged by his results, Dr. O’Shaughnessy commenced patient treatment with marijuana for pain and muscle spasms. Further experiments indicated that marijuana was beneficial in the treatment of stomach cramps, migraine headaches, insomnia and nausea. Marijuana was also proven to be an effective anticonvulsant.
From the 1840s to the 1890s, hashish and marijuana extracts were among the most widely prescribed medications in the United States The 1850 United States Census records 8,327 marijuana plantations, each larger than 2000 acres. Recreational use of marijuana was not evident until early in the 20th century. Marijuana cigarettes became popular, introduced by migrants workers that brought marijuana with them from Mexico. With the onset of Prohibition, recreational use of marijuana skyrocketed. During the early 1930s, hash bars could be found all across the United States.
Although protested by the American Medical Association, the 1937 Marijuana Tax Act banned the cultivation and use of cannabis by federal law. Under the law, cultivation, distribution and consumption of cannabis products for medicinal, practical or recreational was criminalized and harsh penalties were implemented.”

“Should Professors Cheech and Chong ever receive university tenure teaching the medical history of their favorite subject, the course pack would be surprisingly thick.
As early as 2737 B.C., the mystical Emperor Shen Neng of China was prescribing marijuana tea for the treatment of gout, rheumatism, malaria and, oddly enough, poor memory. The drug’s popularity as a medicine spread throughout Asia, the Middle East and down the eastern coast of Africa, and certain Hindu sects in India used marijuana for religious purposes and stress relief. Ancient physicians prescribed marijuana for everything from pain relief to earache to childbirth…
By the late 18th century, early editions of American medical journals recommend hemp seeds and roots for the treatment of inflamed skin, incontinence and venereal disease. Irish doctor William O’Shaughnessy first popularized marijuana’s medical use in England and America. As a physician with the British East India Company, he found marijuana eased the pain of rheumatism and was helpful against discomfort and nausea in cases of rabies, cholera and tetanus.”

“When talking about the drug, marijuana and cannabis both have the same meaning. When talking botanically – talking about the plant genus – we use the word Cannabis. Cannabis is a flowering plant genus that includes three acknowledged varieties:
The three types originally come from South and Central Asia.”
“Cannabis has been used for hundreds of years by humans, for fiber (hemp), seed oils, seed, medical treatment and recreationally.
This article focuses on cannabis’ medicinal and recreational aspects.”

“Marijuana is not a “gateway” drug that predicts or eventually leads to substance abuse, suggests a 12-year University of Pittsburgh study. Moreover, the study’s findings call into question the long-held belief that has shaped prevention efforts and governmental policy for six decades and caused many a parent to panic upon discovering a bag of pot in their child’s bedroom.
The Pitt researchers tracked 214 boys beginning at ages 10-12, all of whom eventually used either legal or illegal drugs. When the boys reached age 22, they were categorized into three groups: those who used only alcohol or tobacco, those who started with alcohol and tobacco and then used marijuana (gateway sequence) and those who used marijuana prior to alcohol or tobacco (reverse sequence).
Nearly a quarter of the study population who used both legal and illegal drugs at some point — 28 boys — exhibited the reverse pattern of using marijuana prior to alcohol or tobacco, and those individuals were no more likely to develop a substance use disorder than those who followed the traditional succession of alcohol and tobacco before illegal drugs, according to the study, which appears in this month’s issue of the American Journal of Psychiatry.
“The gateway progression may be the most common pattern, but it’s certainly not the only order of drug use,” said Ralph E. Tarter, Ph.D., professor of pharmaceutical sciences at the University of Pittsburgh School of Pharmacy and lead author of the study. “In fact, the reverse pattern is just as accurate for predicting who might be at risk for developing a drug dependence disorder.”
In addition to determining whether the gateway hypothesis was a better predictor of substance abuse than competing theories, the investigators sought to identify characteristics that distinguished users in the gateway sequence from those who took the reverse path. Out of the 35 variables they examined, only three emerged to be differentiating factors: Reverse pattern users were more likely to have lived in poor physical neighborhood environments, had more exposure to drugs in their neighborhoods and had less parental involvement as young children. Most importantly, a general inclination for deviance from sanctioned behaviors, which can become evident early in childhood, was strongly associated with all illicit drug use, whether it came in the gateway sequence, or the reverse.
While the gateway theory posits that each type of drug is associated with certain specific risk factors that cause the use of subsequent drugs, such as cigarettes or alcohol leading to marijuana, this study’s findings indicate that environmental aspects have stronger influence on which type of substance is used. That is, if it’s easier for a teen to get his hands on marijuana than beer, then he’ll be more likely to smoke pot. This evidence supports what’s known as the common liability model, an emerging theory that states the likelihood that someone will transition to the use of illegal drugs is determined not by the preceding use of a particular drug but instead by the user’s individual tendencies and environmental circumstances.
“The emphasis on the drugs themselves, rather than other, more important factors that shape a person’s behavior, has been detrimental to drug policy and prevention programs,” Dr. Tarter said. “To become more effective in our efforts to fight drug abuse, we should devote more attention to interventions that address these issues, particularly to parenting skills that shape the child’s behavior as well as peer and neighborhood environments.”
Indeed, according to the study, interventions focusing on behavior modification may be more effective prevention tactics than current anti-drug initiatives. For example, providing guidance to parents — particularly those in high-risk neighborhoods — on how to boost their caregiving skills and foster bonding with their children, could have a measurable effect on a child’s likelihood to smoke marijuana. Also, early identification of children who exhibit antisocial tendencies could allow for interventions before drug use even begins.
Although this research has significant implications for drug abuse prevention approaches, Dr. Tarter notes that the study has some limitations. First, as only male behaviors were studied, further investigation should explore if the results apply to women as well. Also, the examination of behaviors in phases beyond alcohol and marijuana consumption in the gateway series will be necessary.
Other study authors include Michael Vanyukov, Ph.D., and Maureen Reynolds, Ph.D., and Levent Kirisci, Ph.D., also of the University of Pittsburgh School of Pharmacy; and Duncan Clark, M.D., Ph.D., of the University of Pittsburgh School of Medicine. The research was funded by the National Institute on Drug Abuse.”

“Chemicals found in cannabis could prove an effective treatment for the inflammatory bowel diseases Ulcerative Colitis and Crohn’s Disease, say scientists.
Laboratory tests have shown that two compounds found in the cannabis plant – the cannabinoids THC and cannabidiol – interact with the body’s system that controls gut function.
Crohn’s Disease and Ulcerative Colitis, which affect about one in every 250 people in Northern Europe, are caused by both genetic and environmental factors. The researchers believe that a genetic susceptibility coupled with other triggers, such as diet, stress or bacterial imbalance, leads to a defective immune response.
Dr Karen Wright, Peel Trust Lecturer in Biomedicine at Lancaster University, will be presenting her soon-to-be published work at The British Pharmacological Society’s Winter Meeting in London today (Thursday).
She said: “The lining of the intestines provides a barrier against the contents of the gut but in people with Crohn’s Disease this barrier leaks and bacteria can escape into the intestinal tissue leading to an inappropriate immune response.
“If we could find a way to restore barrier integrity in patients we may be able to curb the inflammatory immune response that causes these chronic conditions.”
Dr Wright, working with colleagues at the School of Graduate Entry Medicine and Health in Derby, has shown that cells that react to cannabinoid compounds play an important role in normal gut function as well as the immune system’s inflammatory response.
“The body produces its own cannabinoid molecules, called endocannabinoids, which we have shown increase the permeability of the epithelium during inflammation, implying that overproduction may be detrimental,” said Dr Wright.
“However, we were able to reverse this process using plant-derived cannabinoids, which appeared to allow the epithelial cells to form tighter bonds with each other and restore the membrane barrier.”
The research was carried out using cell cultures in a dish but, interestingly, when the team attempted to mimic the conditions of the gut by reducing the amount of oxygen in the cells’ environment, much lower concentrations of cannabinoid were needed to produce the same effect.
Dr Wright added: “What is also encouraging is that while THC has psychoactive properties and is responsible for the ‘high’ people experience when using cannabis, cannabidiol, which has also proved effective in restoring membrane integrity, does not possess such properties.”
The British Pharmacological Society (BPS) – the primary UK learned society concerned with research into drugs and the way they work – is hosting its annual Winter Meeting in London, attracting experts from across the world.
The three-day conference, running from 15 to 17 December 2009, will hear presentations on the latest pharmacological developments to tackle a range of conditions and diseases.”
“Hemp seeds have a plethora of nutrients necessary to the healing process which makes them one of the most nutritious foods on our planet. When we talk about hemp seeds we mean hulled seeds from the hemp plant. Although in the same genus of plants as Marijuana, Hemp does not possess high enough levels of the medicinal and analgesic (pain relieving) compound Tetrahydrocannabinol, also commonly known by its acronym THC, to be considered the same plant. This article is about the healing medicinal value of hulled hemp seeds with respect to their content of essential amino acids (raw protein) and highly unsaturated essential fatty acids…
The fat content and balance of essential fats in hemp seeds is superior to almost every other seed and nut. Hemp has a ratio of Omega-6 to Omega-3 of 3.75 to 1, which according to the World Health Organization is close to perfect for effective metabolism. Hemp also contains other very important co-factor nutrients including chlorophyll, Vitamin E, a complex of B Vitamins including Folic Acid, as well as Phosphorous, Calcium, Magnesium and Potassium…”

“Biological activity of cannabinoids is caused by binding to two cannabinoid receptors CB1 and CB2. Psychoactive is not only tetrahydrocannabinol (THC) but also: cannabidiol, cannabigerol or cannabichromen. Formerly, the usefulness of hemp was assessed in the relation to temporary appeasement of the symptoms of some ailments as nausea or vomiting.
Present discoveries indicates that cannabis-based drugs has shown ability to alleviate of autoimmunological disorders such as: Multiple sclerosis (MS), Rheumatoid arthritis (RA) or inflammatory bowel disease. Another studies indicates that cannabinoids play role in treatment of neurological disorders like Alzheimer disease or Amyotrophic lateral sclerosis (ALS) or even can reduce spreading of tumor cells.
Cannabinoids stand out high safety profile considering acute toxicity, it is low possibility of deadly overdosing and side-effects are comprise in range of tolerated side-effects of other medications.
In some countries marinol and nabilone are used as anti vomiting and nausea drug. First cannabis-based drug containg naturally occurring cannabinoids is Sativex. Sativex is delivered in an mucosal spray for patients suffering from spasticity in MS, pain relevant with cancer and neuropathic pain of various origin. Despite the relatively low acute toxicity of cannabinoids they should be avoid in patients with psychotic disorders, pregnant or breastfeeding woman. Cannabinoids prolong a time of reaction and decrease power of concentration that’s why driving any vehicles is forbidden.
Cannabis side-effects varies and depend from several factors like administrated dose, rout of administration and present state of mind. After sudden break from long-lasting use, withdrawal symptoms can appear, although they entirely disappear after a week or two.”
“Anecdotal evidence suggests a beneficial effect of cannabis on spasticity as well as pain. Recently, randomized, double-blind, placebo-controlled studies have confirmed the clinical efficacy of cannabinoids for the treatment of spasticity in patients with MS. Based on these data, nabiximols (Sativex), a 1:1 mix of Δ-9-tetrahydrocannabinol and cannabidiol extracted from cloned Cannabis sativa chemovars, received approval for treating MS-related spasticity in various countries around the globe. In this article we review the current understanding of cannabinoid biology and the value of cannabinoids as a symptomatic treatment option addressing spasticity in patients with MS.
Based on individual case reports, the consumption of plant parts, specifically, the resin of the Cannabis sativa hemp plant, has, for years, been attributed to the capacity to reduce the symptoms of multiple sclerosis (MS), such as spasticity, neuropathic pain, tremor, and disturbed bladder function. As characterization of the endocannabinoid system and its role in the motor system and pain processing continue to advance, there is increasing evidence of a scientific basis for the postulated therapeutic effect of cannabis derivatives.
The oromucosal administration of THC and CBD in a 1:1 ratio has proven to be a well tolerated therapeutic option for treating spasticity in patients with MS who respond poorly to conventional antispastic drugs. Assessment of the efficacy is limited by the fact that spasticity as a symptom is very difficult to measure reliably, objectively, and validly. Current study data support the position that the beneficial effects of nabiximols on subjective and objective endpoints in a selected patient sample outweigh the adverse pharmaceutical effects. The effects of long-term nabiximols treatment on neuropsychological processes and the structure of the endocannabinoid system need to be further characterized.”
