Cancer and Marijuana

Since I’ve not managed to make a grand unified Marijuana posting, I’ve decided to “move on” and do it in chunks. Some things are amenable to the “one full story”, others more to “bits and pieces”.

So the latest news is just that the National Institutes of Health have decided to throw in the towel on PC and admit that it kills cancer cells. Details to elaborate over many years, no doubt.

Marijuana destroys Cancer Tumors says NIH and new Study
By Mark Wachtler

July 25, 2014. Norwich, England. (ONN) The US federal government and the National Institutes of Health (NIH) have quietly confirmed what some of us have known for years – that marijuana somehow fights cancer cells without harming healthy cells. Now, and the NIH have actually published that fact, reversing four decades of disinformation and propaganda against the natural remedy on behalf of multi-national pharmaceutical corporations. And to top it off, the results of a just-released study demonstrates how it happens.

Now I cite this 2014 article because this story was just now reaching the ‘regular news’. I saw it on some “cable” TV news channel just about a week ago. Clearly some news travels faster than other to your TV set…

Study discovers how marijuana shrinks tumors

Cancer is big business and big money. Many have long suspected that the cure for cancer has always been held hostage by the powers that be so Wall Street corporations can continue to rake in $125 billion a year fighting the disease with radiation, pills and endless surgeries. The National Cancer Institute alone has taken in and spent an estimated $90 billion allegedly trying to find a cure for cancer. Image, all they had to do was ask a teenager or just test a documented 3,000-year-old medical treatment. Marijuana is the first known medical treatment used by humans, literally dating back to roughly 1,000 BC.

So what’s some of the “story behind the story”? You know, that technical stuff most reports glaze at…

Note this is from 2002. Not exactly “new news”.

Targeting CB2 cannabinoid receptors as a novel therapy to treat malignant lymphoblastic disease.

McKallip RJ1, Lombard C, Fisher M, Martin BR, Ryu S, Grant S, Nagarkatti PS, Nagarkatti M.

In the current study, we examined whether ligation of CB2 receptors would lead to induction of apoptosis in tumors of immune origin and whether CB2 agonist could be used to treat such cancers. Exposure of murine tumors EL-4, LSA, and P815 to delta-9-tetrahydrocannabinol (THC) in vitro led to a significant reduction in cell viability and an increase in apoptosis. Exposure of EL-4 tumor cells to the synthetic cannabinoid HU-210 and the endogenous cannabinoid anandamide led to significant induction of apoptosis, whereas exposure to WIN55212 was not effective. Treatment of EL-4 tumor-bearing mice with THC in vivo led to a significant reduction in tumor load, increase in tumor-cell apoptosis, and increase in survival of tumor-bearing mice. Examination of a number of human leukemia and lymphoma cell lines, including Jurkat, Molt-4, and Sup-T1, revealed that they expressed CB2 receptors but not CB1. These human tumor cells were also susceptible to apoptosis induced by THC, HU-210, anandamide, and the CB2-selective agonist JWH-015. This effect was mediated at least in part through the CB2 receptors because pretreatment with the CB2 antagonist SR144528 partially reversed the THC-induced apoptosis. Culture of primary acute lymphoblastic leukemia cells with THC in vitro reduced cell viability and induced apoptosis. Together, the current data demonstrate that CB2 cannabinoid receptors expressed on malignancies of the immune system may serve as potential targets for the induction of apoptosis. Also, because CB2 agonists lack psychotropic effects, they may serve as novel anticancer agents to selectively target and kill tumors of immune origin.

Key takaway here being that it is both THC and Cannabinoids that have activities, just in different parts of the biochemistry. The argument for “the whole package” instead of drug extracts has some merit.

When we get to 2012, things are continuing to develop.

Cannabidiol inhibits lung cancer cell invasion and metastasis via intercellular adhesion molecule-1.

Ramer R1, Bublitz K, Freimuth N, Merkord J, Rohde H, Haustein M, Borchert P, Schmuhl E, Linnebacher M, Hinz B.

Cannabinoids inhibit cancer cell invasion via increasing tissue inhibitor of matrix metalloproteinases-1 (TIMP-1). This study investigates the role of intercellular adhesion molecule-1 (ICAM-1) within this action. In the lung cancer cell lines A549, H358, and H460, cannabidiol (CBD; 0.001-3 μM) elicited concentration-dependent ICAM-1 up-regulation compared to vehicle via cannabinoid receptors, transient receptor potential vanilloid 1, and p42/44 mitogen-activated protein kinase. Up-regulation of ICAM-1 mRNA by CBD in A549 was 4-fold at 3 μM, with significant effects already evident at 0.01 μM. ICAM-1 induction became significant after 2 h, whereas significant TIMP-1 mRNA increases were observed only after 48 h. Inhibition of ICAM-1 by antibody or siRNA approaches reversed the anti-invasive and TIMP-1-upregulating action of CBD and the likewise ICAM-1-inducing cannabinoids Δ(9)-tetrahydrocannabinol and R(+)-methanandamide when compared to isotype or nonsilencing siRNA controls. ICAM-1-dependent anti-invasive cannabinoid effects were confirmed in primary tumor cells from a lung cancer patient. In athymic nude mice, CBD elicited a 2.6- and 3.0-fold increase of ICAM-1 and TIMP-1 protein in A549 xenografts, as compared to vehicle-treated animals, and an antimetastatic effect that was fully reversed by a neutralizing antibody against ICAM-1 [% metastatic lung nodules vs. isotype control (100%): 47.7% for CBD + isotype antibody and 106.6% for CBD + ICAM-1 antibody]. Overall, our data indicate that cannabinoids induce ICAM-1, thereby conferring TIMP-1 induction and subsequent decreased cancer cell invasiveness.

So the cannabinoids also slow the spread and inhibit invasiveness.

Then there are the other things it does that can make pain and inflammation less. (Frankly, if they come out with a THC reduced high CBD variety that reduces arthritic inflammation a whole load of folks will be lining up, me included.)

Have any preclinical (laboratory or animal) studies been conducted using Cannabis or cannabinoids?

Preclinical studies of cannabinoids have investigated the following:

Antitumor activity

Studies in mice and rats have shown that cannabinoids may inhibit tumor growth by causing cell death, blocking cell growth, and blocking the development of blood vessels needed by tumors to grow. Laboratory and animal studies have shown that cannabinoids may be able to kill cancer cells while protecting normal cells.

A study in mice showed that cannabinoids may protect against inflammation of the colon and may have potential in reducing the risk of colon cancer, and possibly in its treatment.

A laboratory study of delta-9-THC in hepatocellular carcinoma (liver cancer) cells showed that it damaged or killed the cancer cells. The same study of delta-9-THC in mouse models of liver cancer showed that it had antitumor effects. Delta-9-THC has been shown to cause these effects by acting on molecules that may also be found in non-small cell lung cancer cells and breast cancer cells.

A laboratory study of cannabidiol (CBD) in estrogen receptor positive and estrogen receptor negative breast cancer cells showed that it caused cancer cell death while having little effect on normal breast cells. Studies in mouse models of metastatic breast cancer showed that cannabinoids may lessen the growth, number, and spread of tumors.

A laboratory study of cannabidiol (CBD) in human glioma cells showed that when given along with chemotherapy, CBD may make chemotherapy more effective and increase cancer cell death without harming normal cells. Studies in mouse models of cancer showed that CBD together with delta-9-THC may make chemotherapy such as temozolomide more effective.

Stimulating appetite

Many animal studies have shown that delta-9-THC and other cannabinoids stimulate appetite and can increase food intake.

Pain relief

Cannabinoid receptors (molecules that bind cannabinoids) have been studied in the brain, spinal cord, and nerve endings throughout the body to understand their roles in pain relief.

Cannabinoids have been studied for anti-inflammatory effects that may play a role in pain relief.

Animal studies have shown that cannabinoids may prevent nerve problems (pain, numbness, tingling, swelling, and muscle weakness) caused by some types of chemotherapy.

Nausea and vomiting

Cannabinoid receptors found in brain cells may have a role in controlling nausea and vomiting. Animal studies have shown that delta-9-THC and other cannabinoids may act on cannabinoid receptors to prevent vomiting caused by certain types of chemotherapy.

Anxiety and sleep

Cannabinoid receptors found in the brain and other parts of the nervous system may be involved in controlling mood and anxiety.
Anti-anxiety effects of cannabidiol (CBD) have been shown in several animal models.

Here’s an older study (2006) that is interesting as it specifically calls out angiogenisis. Typically a tumor starts growth without much blood supply. Later, blood vessels form to feed it (angiogenisis) and if that step doesn’t happen, it has a more limited future growth. In any case, these were folks with recurrent and essentially untreatable cancers who were given an experimental dose of THC mostly to see if it had horrid bad effects or if it was OK to test it on less terminal folks… Yeah, medicine is like that…

Δ9-Tetrahydrocannabinol (THC) and other cannabinoids inhibit tumour growth and angiogenesis in animal models, so their potential application as antitumoral drugs has been suggested. However, the antitumoral effect of cannabinoids has never been tested in humans. Here we report the first clinical study aimed at assessing cannabinoid antitumoral action, specifically a pilot phase I trial in which nine patients with recurrent glioblastoma multiforme were administered THC intratumoraly. The patients had previously failed standard therapy (surgery and radiotherapy) and had clear evidence of tumour progression. The primary end point of the study was to determine the safety of intracranial THC administration. We also evaluated THC action on the length of survival and various tumour-cell parameters. A dose escalation regimen for THC administration was assessed. Cannabinoid delivery was safe and could be achieved without overt psychoactive effects. Median survival of the cohort from the beginning of cannabinoid administration was 24 weeks (95% confidence interval: 15–33). Δ9-Tetrahydrocannabinol inhibited tumour-cell proliferation in vitro and decreased tumour-cell Ki67 immunostaining when administered to two patients. The fair safety profile of THC, together with its possible antiproliferative action on tumour cells reported here and in other studies, may set the basis for future trials aimed at evaluating the potential antitumoral activity of cannabinoids.

Keywords: cannabinoid; glioblastoma multiforme; pilot clinical study; antitumoral drug

So it didn’t cure the incurable, but did slow it down. At least in this trial. One wonders what a mixed THC / Cannabinoids would do…

Here’s a study from 2015 finding a cannabinoid component useful in breast cancer treatment:

Modulation of the tumor microenvironment and inhibition of EGF/EGFR pathway: Novel anti-tumor mechanisms of Cannabidiol in breast cancer

•CBD inhibits TNBC proliferation, migration and invasion.
•CBD inhibits EGF/EGFR signaling pathway and its downstream targets.
•CBD inhibits GM-CSF, CCL3 and MIP-2 secretion from cancer cells.
•CBD inhibits breast cancer growth and metastasis in two mouse models.
•CBD inhibit M2 macrophage recruitment to the tumor stroma.


The anti-tumor role and mechanisms of Cannabidiol (CBD), a non-psychotropic cannabinoid compound, are not well studied especially in triple-negative breast cancer (TNBC). In the present study, we analyzed CBD’s anti-tumorigenic activity against highly aggressive breast cancer cell lines including TNBC subtype. We show here -for the first time-that .CBD significantly inhibits epidermal growth factor (EGF)-induced proliferation and chemotaxis of breast cancer cells. Further studies revealed that CBD inhibits EGF-induced activation of EGFR, ERK, AKT and NF-kB signaling pathways as well as MMP2 and MMP9 secretion. In addition, we demonstrated that CBD inhibits tumor growth and metastasis in different mouse model systems. Analysis of molecular mechanisms revealed that CBD significantly inhibits the recruitment of tumor-associated macrophages in primary tumor stroma and secondary lung metastases. Similarly, our in vitro studies showed a significant reduction in the number of migrated RAW 264.7 cells towards the conditioned medium of CBD-treated cancer cells. The conditioned medium of CBD-treated cancer cells also showed lower levels of GM-CSF and CCL3 cytokines which are important for macrophage recruitment and activation. In summary, our study shows -for the first time-that CBD inhibits breast cancer growth and metastasis through novel mechanisms by inhibiting EGF/EGFR signaling and modulating the tumor microenvironment. These results also indicate that CBD can be used as a novel therapeutic option to inhibit growth and metastasis of highly aggressive breast cancer subtypes including TNBC, which currently have limited therapeutic options and are associated with poor prognosis and low survival rates.

In Conclusion

There ARE negatives to Marijuana consumption, especially for young boys where it can interfere in the testosterone / estrogen balance results (link in another article later). It also causes some degree of confusion (personal experience …) and it can even cause a minor kind of paranoia if you are sitting in a Denny’s at 1 AM scarfing down pancakes and 2 cops sit down at the counter across from your booth… but I digress…

So for me, it has never held a whole lot of interest. I “tried it” back in the ’70s and largely moved on.


It does look to have very definite medical properties in several areas and especially for anyone with terminal cancer, well ‘worth a shot’. I’d not mix it with any other cancer treatment without the M.D. saying “OK”, but once you have that “nothing more we can do” line in your face, it looks like a reasonable “well hell, why not” response.

I’ve found many other such articles, including one specifically about prostate cancer. It does look to be particularly effective in the cancers of the estrogen / testosterone sensitive tissues (my guess). Since just about any guy over 60 to 70 is looking at eventual prostate cancer formation, I expect we’ll be seeing a whole lot more old guys with red eyes in our future ;-)

I’d also expect we’ll be seeing a large number of derivative drugs come out of it as it gets processed through the drug industry.

I’m not going to be headed out to ‘score a baggy’ any time soon since among other things I have a tendency for it to just put me to sleep (part of why that ’70s experiment was a short one… pay a chunk of change to stuff down a whole bag of Chips and Dip and then fall asleep? Why?…) but it is pretty clear a lot of folks don’t react that way. For anyone on chemo, that might be a feature anyway…

So count me on the side of those who endorse legalization of Marijuana (for whatever use… you are an adult and it is your body, not mine and not the government’s and certainly not your employer’s…) even if it isn’t particularly attractive to me. Besides, some day I might need something that shrinks tumors, slows or stops their spread, and inhibits angiogeneses all while making chemo tolerable and getting me to eat even while feeling horrid.

In short, looks to me like it works at least as well as most of the stuff pushed on us by The Medical and Drug Establishment.

    Marijuana has very carcinogens substances in it, its anticancer properties stop every person practically getting cancer.

  2. p.g.sharrow says:

    The Federal Government knows about all this and has obtained patents on all medical uses of Cannabis. Pharmaceutical cannabanoids are being readied for production and marketing in the US by exclusive agreements to Big Pharma only…pg

  3. Ralph B says:

    They didn’t say the best way to use it…brownies? Pipe? :-)

  4. E.M.Smith says:

    @Ralph B:

    Since burning things makes all sorts of horrid and carcinogenic things, I’d vote for brownies or as an extract. Acetone nicely dissolves all the active agents and puts them into suspension, then evaporates rapidly (AWAY FROM IGNITION SOURCES AS IT BURNS EASILY AND WELL!!!) leaving behind a nice green ‘hash oil’. Mix with syrup and Drizzle on ice cream sounds good to me ;-)

    Oh, and I understand warm melted butter does an extract as well. Good for all sorts of baking…


  5. p.g.sharrow says:

    a dose of acetone extracted “wax” is 1 to 2 grains and is very difficult to immense in water based things. It dissolves in oils very easily. To extract with butter or oils is terribly wasteful of butter and cannabis. Cold Water can be used to separate the resin tricones from the vegetable matter and can yield a clean product but is wasteful of the total resin available. CO2 extraction yields the cleanest resin with the least loss, but requires sophisticated expensive equipment. Butane extraction is very easy and is VERY DANGEROUS! Don’t do it! Use Acetone if you must …pg

    Thinking back to the mid to late ’60’s at Humboldt. The Filthy Speech movement at Berkley was in full flower. One fellow was obviously quite bright, but got started on pot, and possibly other things. Over a period of about 4 or so months he went from vibrant leader to a bit of a veg. That soured me on any recreational application. I do know some who do the brownie or other food application in disease cases, and they say it helps. sometimes a lot. At least locally, there are now multiple stores selling it in WA. If it is medically effective, have at it. Went to the barber just before Christmas and he had gotten a tip in the form of a baggie. When you tip the barber with a baggie, acceptance has arrived.

  7. Lars Silén: Reflex och spegling says:

    Regarding your side comment about arthritis. Have you looked at Boron or more specifically Borax. If you look at Jamaica with extremely low levels of Boron and compare that to for example Israel with high levels of Boron you see that in Jamaica there is a 70% incidence of arthritis and in Israel it is only 1%. You find other similar examples elsewhere. For this reason I have started to take ca. 100 mg Borax (ca. 10 mg Boron) per day. I am not able to say anything specific yet due to the short time I have tested it. No adverse reactions though.

    I recently wrote an blog post about vitamin C, Iodine and Boron. The article studies the recommended levels of vitamin C, Iodine and Boron as given by the authorities. It is strange to notice that the recommended intake levels seem to be extremely low. Are these extremely low recommendations actually given to produce an endless flow of patients into the medical system?
    The blog post (unfortunately in swedish but with some interesting videos and references in English) is found here:

  8. E.M.Smith says:


    Yes, I looked at Boron some time back and it does seem to help. Tend to forget to take it, though, as I mix my own and that is like work ;-)

    Swedish isn’t that hard to read, with some study. Just a few words are unique with many others similar to English or German. I worked at Ericsson for over a year once. By the end I could decipher office memos in Swedish. Will be fun to refresh those old skills…

    The old Swedish movies are excellent, if a bit slow paced by modern standards. Though I need the captions to follow the spoken form. Ingmar Bergman, Max von Sydow, Ingred Bergman,… what’s not to like?

    So no need to apologise for using Swedish in your blog; think of it as an opportunity for cultural enrichment for the rest of us ;-)

  9. Lars Silén: Reflex och spegling says:

    The language of the blog is intentionally Swedish for several reasons. There are a number of really good blogs in English, among them your blog, but not very many sceptical, technical blogs in Swedish. I like your wide interests in very different topics … probably because I am similar in that respect :) !

  10. Lars Silén: Reflex och spegling says:

    I forgot to say that from a European point of view language and knowing several languages isn’t very strange and if I remember correctly you have your feet in at least two different languages and cultures. Many European languages are actually fairly close as you said /being able to quite easily decrypt Swedish memos . Swedish isn’t very difficult from an English starting point. A Swedish speaking person should understand Norwegian and at least written Danish. Knowing a little German, easy from a Swedish starting point, allows you to roughly read Dutch … the system is the same for the Latin languages.

    We are almost colleagues because I worked for Ericsson for roughly fifteen years in product design and as an innovation coach.

    I need to thank you for reminding me about boron. Did the short method of measure (damp finger tip, touch borax, lick off…) and discomfort dropped a lot inside 4 hours…

    FWIW: I had 6 years of Spanish in 5-8th grade grammar school, freshman and sophomore high school. 18 units of French, 6 of German and an attempt at Russian at University. Swedish and Norwegian via tapes at home ( with a brief flirtation with an Icelandic tape…), limited Italian from tapes for / on a business trip to Italy, some Portuguese as I was teaching English to kids from Brazil, looked at Esperanto and Ido and found other Romance languages mostly close enough to get the sense of it. (Catalan, Romanch, …) Oh, and a linguistics class along with a dozen or two computer languages. One weekend was spent with a “teach yourself Greek” book to some benefit and I’m presently working on beginners Latin.

    I’ve done a survey of (read about, with examples) a couple of dozen others, and can use Japanese for karate and ordering food :-)

    I seem to have a nack for languages… and yes, after the first 3 or so, others start to look like variations on a theme. English being a mix of German, Viking, French, Latin and bits of Greek with additions from all other languages is also decent preparation for variety… though my spelling is screwed up…

    I was at Ericsson in Menlo Park, California doing computer operations work and a site shutdown.

  14. andysaurus says:

    Sorry E.M. I have nothing to add, but am vastly interested in the topic as my wife has secondary breast cancer in her bones. Under control but painful. It seems that Mary Jane addresses all the aspects for which she is taking medication, including: rebuilding her spine, stopping metastasis, pain management, depression, diabetes, cardiac arrhythmia. If it fixed her coeliac disease she would be home free (once we overcame the legal aspects, that is).
    I don’t know how to follow the thread without posting something.

  15. To add to the MJ cure, maybe a good dose of the ‘flu or Dengue fever might be useful to burn out the cancerous cells, which don’t have the same resilience as normal body cells. The relevant links are and , but a search will likely find more. Anti-cancer drugs exploit the difference, and chemotherapy or radiotherapy are intended to poison you just short of death. That’s why people lose hair in the process, since the hair follicles are also less durable than other cells. There’s thus a reasonable basis for a fever doing the same thing, and it would be important to not take fever-reducing medicines such as Paracetamol/Tylenol to make it easier on the patient. Maybe a cooling water-jacket for the head would be a good thing, though, to keep the brain cooler than 42°C. If it’s a brain cancer, maybe a closer temperature control would be required.

  16. E.M.Smith says:


    No worries. You can feel free to comment at will, even if it is just “hi” or “ping!” :-)

    Btw, I have a ‘ posting in progress’ about wheat and coeliac disease. Short form: Try gluten free and see what happens. For some folks, that is the cause. (Avoid wheat, rye, triticale, barley. For a few folks, oats and rice too, though rarely.)

    I know of a person who is adding cannabis to their radiation/chemo with excellent results. There is a paper out (have to look it up) showing that cannabis in conjunction with radiation/chemo greatly reduces the amount of radiation chemo required.

    @M Simon; good set of links. It is strange to me that GOD has given us such a wonderful and inexpensive, easy to grow medication that works with our bodies, While Government Bureaucrats and politicians do everything possible to eradicate it. Meanwhile require us to use medications that destroy our health. This WAR on the people must be stopped.
    Bureaucrats always destroy the society the manage, ALWAYS. They must be brought to heel. It is them or us. We don’t need them to survive. Without us they starve…pg

  22. E.M.Smith says:


    Feel free to post more links here. I have nothing against it. ( I just don’t want them spread over a dozen unrelated articles as then I can’t find them easily in the future…). Every link you post is a bit less R&D I have to do…


    I’d probably be a greater advocate for it but for 2 (perhaps idiosyncratic) things:

    1) In college I tried it for a few months. It took me over 1/2 YEAR to get my memory back to near normal. Prior to this it was nearly photographic. During the time I was forgetful. After that, about normal. After a few more years, I slowly regained the “exceptional” level, but never ever quite as super sharp again. (Though I did score almost off the charts on the GMAT a decade later ;-)

    2) Whenever I’ve tried it since (only as ‘one off’ events every few years at a party or two) I’ve reasonably promptly gone to sleep. I’m good for about 1/2 hour of ‘experience’ and then it’s nap time. No idea why.

    So on the one hand, I’m unwilling to risk the major facility that lets me be me and make money. On the other hand, what’s the point of it if you are rapidly asleep? Just brush your teeth and turn out the lights is a lot cheaper…

    Yet I know other folks without those “issues”, so I figure it’s just me. And I’m OK with a diet of Scotch and Irish Coffee ;-)
