Cannabis Inhalation Associated With Spontaneous Tumor Regression, Study Says

    Cannabis inhalation is associated with spontaneous brain tumor regression in two subjects, according to a pair of case reports to be published in Child’s Nervous System, the official journal of the International Society for Pediatric Neurosurgery.

    Investigators at the British Columbia Children’s Hospital in Vancouver documented the mitigation of residual tumors in two adolescent subjects who regularly inhaled cannabis. Authors determined that both subjects experienced a “clear regression” of their residual brain tumors over a three-year-period.

    “Neither patient received any conventional adjuvant treatment” during this time period, investigators wrote. “The tumors regressed over the same period of time that cannabis was consumed via inhalation, raising the possibility that cannabis played a role in tumor regression.”

    Researchers concluded, “Further research may be appropriate to elucidate the increasingly recognized effect of cannabis/cannabinoids on gliomas (brain cancers).”

    A 2006 pilot study published in the British Journal of Cancer previously reported that the intratumoral administration of the cannabinoid THC was associated with reduced tumor cell proliferation in two of nine human subjects with brain cancer.

    Separate preclinical studies assessing the anticancer activity of cannabinoids and endocannabinoids indicate that the substances can inhibit the proliferation of various types of cancerous cells, including breast carcinoma, prostate carcinoma, and lung cancer.

    Commenting on the two new case reports, researcher Jahan Marcu — who has previously documented the inhibitory effects of cannabinoids on human glioblastoma cell proliferation and survival — wrote in the blog Freedom Is Green: “Can marijuana contribute to the regression or remission of certain cancers? Given the slow progress of clinical trials for whole plant Cannabis, it can be frustrating waiting for years, even decades, trying to answer these vital questions. But for the two young women with brain cancer in (this) report, a shift to a cannabis lifestyle may have made a difference.”

      Current situation with cannabis/medicinal cannabis legalization shows that the dangerous philosophies of “radical pragmatism”, shared by both Marxists and Nazis, are well and alive in contemporary America when it comes to anti-cannabis policies! The extremists currently in charge of the DEA will stop at nothing to derail the medicinal cannabis program and the Will of Voters who voted for it. I wish I could see the day when the senseless and shameful witch-hunts against citizens over a natural medicinal plant cannabis finally end, and they will! I predicted a long time ago that anti-cannabis repression will lead to increased hard drug and alcohol abuse because they are not “easily” detected in random drug screens, especially when it comes to the “window” of their detection. All these so-called “random drug screens” unfairly target the users of the safest substance of them all – cannabis! I can’t wait to see the day when these shameful and senseless witch-hunts against citizens in connection with cannabis medicinal plant will stop altogether. I stressed many times already that no system, no matter of how repressive, can survive on a series of “un-realities”. Current undisguised assault by the “radical pragmatists” from the DEA on the will of the people of Montana (and now also Hollywood) demonstrate their delusional thinking their attempts in suppression science (and people’s will) will be more successful than those of Inquisition, Gestapo, or KGB! I wish I could live to see these people’s miserable and disgraceful failure! Everything that the DEA and its allies use to intimidate citizens (and politicians) about the remarkable cannabis plant is based on unreality: cannabis is NOT physically addictive, the so-called “gateway drug theory” is NOT scientifically valid, smoking cannabis does NOT lead to increase in the risk of lung cancer, legalization in other countries did NOT lead to increased cannabis use, and in addition it is proven that cannabis use suppresses violent behavior. To claim that drug Marinol is the same as medicinal cannabis is to make yet another break from reality. Cannabis is immeasurably safer than alcohol, (and most currently used prescription drugs – do we even notice their devastating potential side effects at their TV commercials?), and be so ignorant as to say that cannabis plant does not have medicinal value is to be out of touch with “reality” altogether. Legalization of medicinal cannabis is non-partisan because all of us can get sick and be able to take advantage of its remarkable medicinal properties. Let’s reject the prohibitionist fear-tactics as they have no substance to them, and legalize cannabis in all 50 States without further delay!

      Well, there goes the old ” Doing it for the safety of our children” arguement. A. What could be more beneficial than a substance that literally can not be over-dosed? B. Which leads me to believe that if you are fighting a tumor by means of Cannabis consumption–then you would not have to worry about over-medicating in order to beat the tumor. C. Therefore allowing the mrdication(cannabis), to kick cancer-@ss faster & with less down time in between treatments(since the body isn’t spending time recouping from radiation/toxins). Which also means the tumor has less time to rebound before the next wave of medication is sent in to fight.

      A leads to B, leads to C.

      This is great news. But I’m a little worried… if a study showed the opposite, would you post it? It’s getting hard to tell whether cannabis is really a purely benevolent miracle drug, or whether my sources of cannabis news are completely biased…

      With the Increase of Evidence of Positive health benefits, and the increased evidence of the harms of Prohibition I think it is time to put together a complete documentary about the total cost of continued prohibition. All of it, Let’s really ramp up the debate among ourselves and if the government jumps in great, But I say it is no longer necessary for them to be here. Let their actions or the lack thereof speak for them.

      Hmmmmm. This got me thinking. I know there are many probable benefits (and many more PROVEN benefits) from using cannabis. Particularly regarding cancer(s).

      With the problems the Japanese are having with the release of radiation from their nuclear power plants, and the near certainty of even more leaking, there will undoubtedly be many cases of cancer eventually linked to their situation.

      Why not connect the dots? Let’s send some MEDICAL cannabis to the Japanese. I’m sure growers would be able (and more than willing) to dedicate at least a plant or two to the effort. Let’s send enough so that those that want to use it for MEDICAL reasons have a supply to do just that.

      The US government should relax the restrictions on, (or flat out legalize) cannabis. This is a HUMANITARIAN relief effort. Let our planters plant. Let our growers grow. To refuse this is to refuse to provide humanitarian relief to another nation in a time of national crisis. (Depending on how bad this gets, it could in fact be a worldwide crisis).

      Just say it’s OK, and give us an address in Japan to send our ‘relief’ medication to. We can handle the rest. There would be NO COST to EITHER of our governments. A true humanitarian effort by true humanitarians.

      Will our government give us the OK to help? Or will they ignore the evidence, and condemn the Japanese people to a life with cancer? Heck, if they’d let them plant even JUST hemp in Japan, that would absorb the radiation on and in the soil.

      My question is, ‘what is it going to take?’. Do we need to watch thousands and thousands of people die now and in the future, because our government has an illegal and unsubstantiated view of cannabis?

      Well, it’s worked for the last 70 years, so why not deny the sick and dying one of the safest and arguably most effective medicines on the planet?

      The majority of our politicians don’t care. After all, it isn’t THEIR kids that will be getting sick and dying. I guarantee you, if it were, cannabis would suddenly be legal!

      JUST SAY OK.

      My 2¢.
