Another Reason Marijuana is Illegal: It Prevents The Spread of HIV
The overwhelming evidence of the curative powers of marijuana and cannabinoids leave little doubt that the pharmaceutical industry is behind marijuana prohibition laws. The amount of research now validating the truly remarkable nature of this healing plant is simply enormous. According to new findings published in the journal PLoS ONE, researchers have now have now discovered that marijuana-like chemicals trigger receptors on human immune cells that can directly inhibit a type of human immuno-deficiency virus (HIV) found in late-stage AIDS.
The U.S. Patent 6630507 was specifically initiated when researchers found that cannabinoids had specific antioxidant properties making them useful in the treatment and prophylaxis of wide variety of oxidation associated diseases, such as ischemic, age-related, inflammatory and autoimmune diseases. The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and HIV dementia.

Medical marijuana has been typically prescribed to treat pain, debilitating weight loss and appetite suppression in patients with advanced AIDS. However, Mount Sinai School of Medicine researchers have produced the first study to reveal how the marijuana receptors found on immune cells--called cannabinoid receptors CB1 and CB2--can influence the spread of the virus.
Unfortunately, the scientists will use the research on the effects of these receptors to develop new drugs to benefit the pharmaceutical industry.

Mihaldas says the studies finally justify what the pro-marijuana community has always know. "Decades of anecdotal and empirical evidence are now being validated by the scientific community, but it's unfortunate they are using this research for their own selfish motives--to take marijuana from its raw medically effective form to one where it will be medically ineffective with processing agents, altering what it was designed to do...heal," proclaimed Mihaldas.
“We knew that cannabinoid drugs like marijuana can have a therapeutic effect in AIDS patients, but did not understand how they influence the spread of the virus itself,” said study author Cristina Costantino, PhD, Postdoctoral Fellow in the Department of Pharmacology and Systems Therapeutics at Mount Sinai School of Medicine. “We wanted to explore cannabinoid receptors as a target for pharmaceutical interventions that treat the symptoms of late-stage AIDS and prevent further progression of the disease without the undesirable side effects of medical marijuana.”
Nonpsychoactive cannabinoids, such as cannabidoil, are particularly advantageous to use because they avoid toxicity that is encountered with psychoactive cannabinoids at high doses useful in the method of the present invention. CBD (Cannabidiol), one of the main constituents of the cannabis plant has been proven medically to relieve many diseases including the inhibition of cancer cell growth. Recent studies have shown it to be an effective atypical anti-psychotic in treating schizophrenia. CBD also interferes with the amount of THC your brain processes, balancing the psychotropic effect of marijuana. That is precisely why the power of raw cannabis is turning heads.
HIV infects active immune cells that carry the viral receptor CD4, which makes these cells unable to fight off the infection. In order to spread, the virus requires that “resting” immune cells be activated. In advanced AIDS, HIV mutates so it can infect these resting cells, gaining entry into the cell by using a signaling receptor called CXCR4. By treating the cells with a cannabinoid agonist that triggers CB2, Dr. Costantino and the Mount Sinai team found that CB2 blocked the signaling process, and suppressed infection in resting immune cells.
The Mount Sinai team infected healthy immune cells with HIV, then treated them with a chemical that triggers CB2 called an agonist. They found that the drug reduced the infection of the remaining cells.
“Developing a drug that triggers only CB2 as an adjunctive treatment to standard antiviral medication may help alleviate the symptoms of late-stage AIDS and prevent the virus from spreading,” said Dr. Costantino. Because HIV does not use CXCR4 to enhance immune cell infection in the early stages of infection, CB2 agonists appear to be an effective antiviral drug only in late-stage disease.
As a result of this discovery, the research team led by Benjamin Chen, MD, PhD, Associate Professor of Infectious Diseases, and Lakshmi Devi, PhD, Professor of Pharmacology and Systems Therapeutics at Mount Sinai School of Medicine, plans to develop a mouse model of late-stage AIDS in order to test the efficacy of a drug that triggers CB2 in vivo.
Now that the scientific evidence is being made public, a concerted effort must be made from all nations to end marijuana-prohibition laws. Holding or possessing a plant should never be a criminal offence and the origins and source for these laws are now coming to light.
