Hey, cancer! We're comin' for you!
First we praised Cancer.gov, the website of the National Cancer Institute, a part of the National Institute of Health, changing their website to acknowledge the antitumoral effects of cannabinoids.
Then we cursed Cancer.gov for scrubbing the reference to the antitumoral effects of cannabinoids.
Now Cancer.gov seems to have expanded its reference page on Laboratory/Animal/Preclinical Studies to go into great detail on the antitumoral effects of cannabinoids:
One study in mice and rats suggested that cannabinoids may have a protective effect against the development of certain types of tumors.
Decreased incidences of benign tumors(polyps and adenomas) in other organs(mammary gland, uterus, pituitary, testis, and pancreas) were also noted in the rats.
Cannabinoids may cause antitumor effects by various mechanisms, including induction of cell death, inhibition of cell growth, and inhibition of tumorangiogenesis and metastasis.
Cannabinoids appear to kill tumor cells but do not affect their nontransformed counterparts and may even protect them from cell death.
In addition, both plant-derived and endogenous cannabinoids have been studied for anti- inflammatory effects.
…phytocannabinoids and endocannabinoids may be useful in the prevention and treatment of colorectal cancer…
…THC is a potent and selective antiviral agent against Kaposi sarcoma-associated herpesvirus…
Many animal studies have previously demonstrated that delta-9-THC and other cannabinoids have a stimulatory effect on appetite and increase food intake.
Cannabinoids may also contribute to pain modulation…
You heard it straight from your federal government at Cancer.gov. Meanwhile over at DEA.gov…
[Marijuana] has a high potential for abuse. [Marijuana] has no currently accepted medical use in treatment in the United States. There is a lack of accepted safety for use of [marijuana] under medical supervision.

Contact your elected representatives and urge them to 'Stop Arresting Marijuana Smokers'.

How can there be a cannabinoid system and not a natural desire? Like a dog to it’s grass. Why aren’t there a thousand lawyers saying stop on every channel? What does humane mean?
Great news! I took a screen shot of the web page just in case they change their minds. http://stash.norml.org/wp-includes/images/smilies/icon_biggrin.gif
