For some time we’ve been pointing out the massive pile of evidence that THC and other cannabinoids have potential as anticancer drugs. A new study out of Thailand demonstrates that THC can fight cholangiocarcinoma – cancer of the bile duct. This is a rare but deadly form of cancer, with only 30 percent of patients still alive after five years, according to the  Cholangiocarcinoma Foundation. Based on these new lab results, the Thai researchers conclude, “THC is potentially used to retard cholangiocarcinoma cell growth and metastasis.”

That alcohol causes cancer isn’t really news, but how it does so hasn’t been fully understood. A new study, published in the journal Alcoholism: Clinical and Experimental Research, adds an important new piece of information. Alcohol, it turns out, stimulates a type of cell transformation that turns cancer cells more aggressive and thus more likely to spread throughout the body.

As we’ve noted before, research shows that cannabinoids (marijuana’s unique, active components) interfere with tumor growth and may actually prevent cancer.

One thing that drives me crazy is the tendency of the media and others to refer to THC as “the active ingredient” in marijuana. While THC is indeed responsible for marijuana’s “high,” it is one of about 80 unique compounds, called cannabinoids, that are not seen in any other plant. Many of these have interesting, potentially significant, medical applications, and are not psychoactive.

Anyone who wants to learn about these other cannabinoids should check out this recent review published in the journal Trends in Pharmacological Sciences. [Read more →]

Among the more interesting pieces of news that came out while I was on vacation the first half of August was a new study in the journal Cancer Prevention Research, which found that marijuana smokers have a lower risk of head and neck cancers than people who don’t smoke marijuana. Alas, this important research has been largely ignored by the news media.

While this type of study cannot conclusively prove cause and effect, the combination of this new study and existing research — which for decades has shown that cannabinoids are fairly potent anticancer drugs — raises a significant possibility that marijuana use is in fact protective against certain types of cancer.

Here in the U.S., medical marijuana is still routinely branded as some sort of sinister “drug legalizer” conspiracy. In Israel, according to a fascinating article in the newspaper Haaretz, the leading conspirator appears to be the Ministry of Health.

Officials have authorized over 700 patients to use marijuana for medical purposes, and expect the number to rise to 1,200 within three months. Authorities are in the process of authorizing five or six producers to handle the needs of this growing patient population. [Read more →]
