“Marijuana has been used for medicinal purposes–relieving stress and pain and fighting hunger and nausea–for centuries if not millennia. But now, a pair of doctors in San Francisco claim that they’ve compiled reliable data showing that a certain compound in cannabis–cannabidiol–may actually cure cancer.”

Study Claims Marijuana Tied to Lower Bladder Cancer Risk – MSN
“New research says smoking pot may be less likely to cause bladder cancer than smoking cigarettes.The finding is potentially valuable, the study authors said, given the ongoing debate over legalizing marijuana for medical purposes.
More frequent marijuana use — smoking pot more than 500 times — was associated with greater risk reduction than infrequent marijuana use — smoking once or twice, the researchers found.
Thomas said that while the study saw a link between smoking marijuana and lower bladder cancer risk, compared to tobacco smokers, it did not prove a cause-and-effect relationship. He couldn’t explain the link, but speculated on the possible mechanism.
“The theory is that there are receptors in the bladder that are affected by cannabis,” he said. The cannabinoids [compounds] in the marijuana may link with the cannabinoid receptors in the bladder and somehow protect against cell changes that can lead to cancer, he said.
A man’s lifetime risk of bladder cancer is almost 4 percent, according to the American Cancer Society. This means about one in 26 men will develop bladder tumors.”

“New research says smoking pot may be less likely to cause bladder cancer than smoking cigarettes.
The finding is potentially valuable, the study authors said, given the ongoing debate over legalizing marijuana for medical purposes.
For the study, the researchers compared the risk of bladder cancer in more than 83,000 men who smoked cigarettes only, marijuana (cannabis) only, or both substances. The investigators found that men who only smoked pot were the least likely to develop bladder cancer over the course of 11 years.
“Cannabis use only was associated with a 45 percent reduction in bladder cancer incidence, and tobacco use only was associated with a 52 percent increase in bladder cancer,” said study author Dr. Anil A. Thomas, a fellow in urology at Kaiser Permanente Medical Center in Los Angeles.”

Smoking lots of marijuana lowers risk for bladder cancer, doctor says
“A new study that spanned 11 years found that smoking marijuana may lower the chances of getting bladder cancer.”
“The study’s not been peer-reviewed yet, USA Today reported. It involved 83,000 men who smoked marijuana, cigarettes or both, Raw Story reported.
The findings, presented at the American Urological Association, found that men who smoked cigarettes increased their risks of bladder cancer, but that men who smoked marijuana only actually decreased their risks, Raw Story reported. Further, the study found that men who smoked both still have a higher chance of bladder cancer, but it was still a lower chance than those who smoked only cigarettes, Raw Story said.
“Cannabis use only was associated with a 45 percent reduction in bladder cancer incidence, and tobacco use only was associated with a 52 percent increase in bladder cancer,” the study’s author, Dr. Anil Thomas, said, Raw Story reported.
And smoking a lot of marijuana brought the greatest positive results.
Those who smoked marijuana more than 500 times a year had even less risk of bladder cancer than those who smoked the drug only once in a while, Raw Story reported.”

Study: No Association Between Cannabis Smoke and Risk of Lung Cancer
“Numerous preclinical studies have documented that cannabinoids possess potent anti-cancer properties, including the inhibition of lung cancer cell growth.
In a recent presentation given at the annual meeting of the American Association of Cancer Research, investigators from the University of California, Los Angeles provided the latest data reaffirming that cannabis consumption is not associated with an elevated risk of lung cancer.

Smoking marijuana lowers risk for bladder cancer
Kaiser Permanente researchers studied 83,000 men ages 45-69 and found marijuana smokers are less likely to get bladder cancer than those who smoke cigarettes.
Smokers who used cannabis only, found a 45% decrease in the cancer opposed to those who used only tobacco. Those smokers found a 52% increase in the disease.
This is all based on smoking marijuana more than 500 times as opposed to the once or twice toker.
The study stems from findings at California Pacific Medical Center in San Francisco. The greenage could actually be the seed to stop the metastasis in many kinds of cancer, including breast, brain and cancer of the prostate.
Well munch on this; marijuana remains classified as the most dangerous controlled substance alongside heroin and LSD. This means the DEA has to approve any clinical trials of the drug. Yet our government obstructs that research.
In the midst of all this, Los Angeles councilman Bill Rosendahl posted this video announcing that his cancer is in remission, thanks to his use of medical marijuana.
Maybe all of this will cause the DEA to reconsider. After all, you want to cure cancer don’t you?”

What Is Marijuana? What Is Cannabis?
“When talking about the drug, marijuana and cannabis both have the same meaning. When talking botanically – talking about the plant genus – we use the word Cannabis. Cannabis is a flowering plant genus that includes three acknowledged varieties:
- Cannabis sativa
- Cannabis indica
- Cannabis ruderalis
The three types originally come from South and Central Asia.”
“Cannabis has been used for hundreds of years by humans, for fiber (hemp), seed oils, seed, medical treatment and recreationally.
This article focuses on cannabis’ medicinal and recreational aspects.”

Cannabinoid receptor systems: therapeutic targets for tumour intervention.
“The past decade has witnessed a rapid expansion of our understanding of the biological roles of cannabinoids and their cognate receptors. It is now certain that Delta9-tetrahydrocannabinol, the principle psychoactive component of the Cannabis sativa plant, binds and activates membrane receptors of the 7-transmembrane domain, G-protein-coupled superfamily.
Several putative endocannabinoids have since been identified, including anandamide, 2-arachidonyl glycerol and noladin ether. Synthesis of numerous cannabinomimetics has also greatly expanded the repertoire of cannabinoid receptor ligands with the pharmacodynamic properties of agonists, antagonists and inverse agonists.
Collectively, these ligands have proven to be powerful tools both for the molecular characterisation of cannabinoid receptors and the delineation of their intrinsic signalling pathways. Much of our understanding of the signalling mechanisms activated by cannabinoids is derived from studies of receptors expressed by tumour cells; hence, this review provides a succinct summary of the molecular pharmacology of cannabinoid receptors and their roles in tumour cell biology.
Moreover, there is now a genuine expectation that the manipulation of cannabinoid receptor systems may have therapeutic potential for a diverse range of human diseases. Thus, this review also summarises the demonstrated antitumour actions of cannabinoids and indicates possible avenues for the future development of cannabinoids as antitumour agents.” http://www.ncbi.nlm.nih.gov/pubmed/14640910
The endocannabinoid system and its therapeutic exploitation.
“The term ‘endocannabinoid’ – originally coined in the mid-1990s after the discovery of membrane receptors for the psychoactive principle in Cannabis, Delta9-tetrahydrocannabinol and their endogenous ligands – now indicates a whole signalling system that comprises cannabinoid receptors, endogenous ligands and enzymes for ligand biosynthesis and inactivation. This system seems to be involved in an ever-increasing number of pathological conditions. With novel products already being aimed at the pharmaceutical market little more than a decade since the discovery of cannabinoid receptors, the endocannabinoid system seems to hold even more promise for the future development of therapeutic drugs. We explore the conditions under which the potential of targeting the endocannabinoid system might be realized in the years to come.” http://www.ncbi.nlm.nih.gov/pubmed/15340387
