Cannabinoid Administration Halts Disease Progression, Decreases Mortality In Primate Version of Human Immunodeficiency Virus (HIV)

The long-term administration of delta-9-THC, the primary psychoactive compound in marijuana, is associated with decreased mortality in monkeys infected with the simian immunodeficiency virus (SIV), a primate model of HIV (human immunodeficiency virus) disease, according to in vivo experimental trial data published in the June issue of the journal AIDS Research and Human Retroviruses.

Investigators at the Louisiana State University Health Sciences Center assessed the impact of chronic intramuscular THC administration compared to placebo on immune and metabolic indicators of SIV disease during the initial six-month phase of infection.

Researchers reported, “Contrary to what we expected, … delta-9-THC treatment clearly did not increase disease progression, and indeed resulted in generalized attenuation of classic markers of SIV disease.” Authors also reported that THC administration was associated with “decreased early mortality from SIV infection” and “retention of body mass.”

Investigators concluded, “These results indicate that chronic delta-9-THC does not increase viral load or aggravate morbidity and may actually ameliorate SIV disease progression.”

Clinical trials have previously documented that the short-term inhalation of cannabis does not adversely impact viral loads in HIV patients, and may even improve immune function.

Updated NORML Report Reviews Nearly 200 Studies On The Therapeutic Use Of Cannabis

NORML has recently posted online the fourth edition of its popular and comprehensive booklet, “Emerging Clinical Applications for Cannabis & Cannabinoids: A Review of the Recent Scientific Literature.”

Updated and revised for 2011, this report reviews approximately 200 newly published scientific studies assessing the safety and efficacy of marijuana and its compounds in the treatment and management of nineteen clinical indications: Alzheimer’s disease, Amyotrophic Lateral Sclerosis (ALS), chronic pain, diabetes mellitus, dystonia, fibromyalgia, gastrointestinal disorders, gliomas and other cancers, hepatitis C, human immunodeficiency virus (HIV), hypertension, incontinence, methicillin-resistant Staphyloccus aureus (MRSA), multiple sclerosis, osteoporosis, pruritus, rheumatoid arthritis, sleep apnea, and Tourette’s syndrome.

Explains the report’s lead author, NORML Deputy Director Paul Armentano: “The conditions profiled in this report were chosen because patients frequently inquire about the therapeutic use of cannabis to treat these disorders. In addition, many of the indications included in this report may be moderated by cannabis therapy. In several cases, preclinical data and clinical data indicates that cannabinoids may halt the progression of these diseases in a more efficacious manner than available pharmaceuticals.”

The updated report also features a new section, authored by osteopath and medical cannabis specialist Dr. Dustin Sulak, highlighting the significance of the endocannabinoid system and its role in maintaining mental and physiological health.

“As we continue to sort through the emerging science of cannabis and cannabinoids, one thing remains clear: a functional cannabinoid system is essential for health,” writes Dr. Sulak. “From embryonic implantation on the wall of our mother’s uterus, to nursing and growth, to responding to injuries, endocannabinoids help us survive in a quickly changing and increasingly hostile environment. As I realized this, I began to wonder: can an individual enhance his/her cannabinoid system by taking supplemental cannabis? Beyond treating symptoms, beyond even curing disease, can cannabis help us prevent disease and promote health by stimulating an ancient system that is hard-wired into all of us? I now believe the answer is yes.”

Full text of the report is now available online here. Hard copies will be available for purchase shortly. Print copies of the third edition of this report will be made available at a reduced rate for those seeking bulk orders. (Please e-mail NORML for further details.)

Medicinal Marijuana Eases Neuropathic Pain In HIV Patients

Oh, so this is why the Feds do everything they can to discourage any investigation into the safety and efficacy of inhaled cannabis.

Medicinal Marijuana Eases Neuropathic Pain in HIV
via The Washington Post

WEDNESDAY, Aug. 6 (HealthDay News) — Medicinal marijuana helps relieve neuropathic pain in people with HIV, says a University of California, San Diego, School of Medicine study.

It included 28 HIV patients with neuropathic pain that wasn’t adequately controlled by opiates or other pain relievers. The researchers found that 46 percent of patients who smoked medicinal marijuana reported clinically meaningful pain relief, compared with 18 percent of those who smoked a placebo.

The study, published online Aug. 6 in Neuropsychopharmacology, was sponsored by the University of California Center for Medical Cannabis Research (CMCR).

“Neuropathy is a chronic and significant problem in HIV patients as there are few existing treatments that offer adequate pain management to sufferers,” study leader Dr. Ronald J. Ellis, an associate professor of neurosciences, said in an UCSD news release. “We found that smoked cannabis was generally well-tolerated and effective when added to the patient’s existing pain medication, resulting in increased pain relief.”

The findings are consistent with and extend other recent CMCR-sponsored research supporting the short-term effectiveness of medicinal marijuana in treating neuropathic pain.

“This study adds to a growing body of evidence that indicates that cannabis is effective, in the short-term at least, in the management of neuropathic pain,” Dr. Igor Grant, a professor of psychiatry and director of the CMCR, said in the UCSD news release.   

By my count, this is the third clinical trial published in just over a year to conclude that inhaling cannabis significantly reduces neuropathic pain. (Read about the others here and here.) And that’s not even including this study that found that low doses of inhaled cannabis are more therapeutic for HIV-positive patients than Marinol (oral synthetic THC).

Kudos to The Washington Post for publicizing this important story. And an extra ‘shout out’ to the Post‘s editors for highlighting that this trial was sponsored by California’s Center for Medical Cannabis Research and not by the US government.
