Reefer Madness Was Abundant At Kansas Medical Marijuana Hearing
There was a hearing today in Kansas dealing with medical marijuana. From what news reports out of Kansas are saying, the meeting was mixed, although I encourage people from Kansas to put their perspective in the comments so that others can know the local scoop. One thing that I read that is really bothering me is the anti-medical marijuana propaganda that was spread by Eric Voth, a physician and the chairman of the Institute on Global Drug Policy. An article from the Topeka Capital-Journal stated, "Voth also said much of Oregon had to halt pre-employment drug screenings after medical marijuana because "they had no usable work force."” Mr. Voth, you are a liar, plain and simple. I live in Oregon, I have applied for jobs in Oregon, and I can assure you that pre-employment drug screenings are considered the standard here, not the exception.
During the meeting, Kansas Representative Ed Trimmer stated the following:
"Do we have any evidence on either side from sources like the National Cancer Institute, the American Medical Association, the New England Journal of Medicine, the American Opthamological Association Journal?" Trimmer asked. "I would hope that we have something in the medical profession that tells us whether these things work or not. I like to base policy on sound research." This is a classic response by people that are uneducated about marijuana. Long gone are the days when politicians can stick their heads in the sand and act like there is no science to back up medical marijuana. Below is ONE of MANY articles out there about the scientifically proven medical benefits of marijuana. Before anti-medical marijuana spin doctors try to spout lies and delay tactics in the future, they should really do their homework:
From NORML Website:
Gliomas (tumors in the brain) are especially aggressive malignant forms of cancer, often resulting in the death of affected patients within one to two years following diagnosis. There is no cure for gliomas and most available treatments provide only minor symptomatic relief.
A review of the modern scientific literature reveals numerous preclinical studies and one pilot clinical study demonstrating cannabinoids' ability to act as antineoplastic agents, particularly on glioma cell lines.
Writing in the September 1998 issue of the journal FEBS Letters, investigators at Madrid's Complutense University, School of Biology, first reported that delta-9-THC induced apoptosis (programmed cell death) in glioma cells in culture. Investigators followed up their initial findings in 2000, reporting that the administration of both THC and the synthetic cannabinoid agonist WIN 55,212-2 "induced a considerable regression of malignant gliomas" in animals. Researchers again confirmed cannabinoids' ability to inhibit tumor growth in animals in 2003.
That same year, Italian investigators at the University of Milan, Department of Pharmacology, Chemotherapy and Toxicology, reported that the non-psychoactive cannabinoid, cannabidiol (CBD), inhibited the growth of various human glioma cell lines in vivo and in vitro in a dose dependent manner. Writing in the November 2003 issue of the Journal of Pharmacology and Experimental Therapeutics Fast Forward, researchers concluded, "Non-psychoactive CBD ... produce[s] a significant anti-tumor activity both in vitro and in vivo, thus suggesting a possible application of CBD as an antineoplastic agent."
In 2004, Guzman and colleagues reported that cannabinoids inhibited glioma tumor growth in animals and in human glioblastoma multiforme (GBM) tumor samples by altering blood vessel morphology (e.g., VEGF pathways). Writing in the August 2004 issue of Cancer Research, investigators concluded, "The present laboratory and clinical findings provide a novel pharmacological target for cannabinoid-based therapies."
More recently, investigators at the California Pacific Medical Center Research Institute reported that the administration of THC on human glioblastoma multiforme cell lines decreased the proliferation of malignant cells and induced cell death more rapidly than did the administration of WIN 55,212-2. Researchers also noted that THC selectively targeted malignant cells while ignoring healthy ones in a more profound manner than the synthetic alternative.
Most recently, Guzman and colleagues reported that THC administration decreases recurrent glioblastoma multiforme tumor growth in patients diagnosed with recurrent GBM. In the first ever pilot clinical trial assessing the use of cannabinoids and GBM, investigators found that the intratumoral administration of THC was associated with reduced tumor cell proliferation in two of nine subjects. "The fair safety profile of THC, together with its possible anti-proliferative action on tumor cells reported here and in other studies, may set the basis for future trials aimed at evaluating the potential antitumoral activity of cannabinoids," investigators concluded. Several additional investigators have also recently called for further exploration of cannabis-based therapies for the treatment of glioma.[8-10]
In addition to cannabinoids' ability to moderate glioma cells, separate studies demonstrate that cannabinoids and endocannabinoids can also inhibit the proliferation of other various cancer cell lines, including breast carcinoma,[11-15] prostate carcinoma,[16-18] colorectal carcinoma, gastric adenocarcinoma, skin carcinoma, leukemia cells,[22-23]neuroblastoma, lung carcinoma,[25-26] uterus carcinoma, thyroid epithelioma, pancreatic adenocarcinoma,[29-30], cervical carcinoma, oral cancer, biliary tract cancer (cholangiocarcinoma) and lymphoma.[34-35]
Studies also indicate that the administration of cannabinoids, in conjunction with conventional anti-cancer therapies, can enhance the effectiveness of standard cancer treatments. Most recently, investigators at the University of California, Pacific Medical Center reported that cannabinoids possess synergistic anti-cancer properties -- finding that the administration of a combination of the plant's constituents is superior to the administration of isolated compounds alone.
Consequently, many experts now believe that cannabinoids "may represent a new class of anticancer drugs that retard cancer growth, inhibit angiogenesis and the metastatic spreading of cancer cells."[38-39]
