Marijuana Use Helps Some Patients Alleviate Symptoms of Bipolar Disorder, Finds New Study

A new study conducted by researchers at Harvard Medical School, Tufts University and McLean Hospital has found that marijuana use may help patients with bipolar disorder to alleviate their symptoms.

The study, titled Joint Effects: A Pilot Investigation of the Impact of Bipolar Disorder and Marijuana Use on Cognitive Function and Mood, was published by the journal PLoS One, as well as the National Institute of Health.

“Marijuana is the most widely used illicit substance in those diagnosed with bipolar I disorder”, states the study’s abstract. “However, there is conflicting evidence as to whether marijuana may alleviate or exacerbate mood symptomatology. As bipolar disorder and marijuana use are individually associated with cognitive impairment, it also remains unclear whether there is an additive effect on cognition when bipolar patients use marijuana.”

Study: Cannabis Use Can Help Treat Symptoms of Bipolar Disorder

Inhaling cannabis can help treat the symptoms of bipolar disorder without any negative cognitive impact, according to a new study published in the journal PLoS ONE.bowl

“Marijuana is the most widely used illicit substance in those diagnosed with bipolar I disorder”, states the study’s abstract. “However, there is conflicting evidence as to whether marijuana may alleviate or exacerbate mood symptomatology.”

Due to this conflicting evidence; “The current study aimed to determine the impact of marijuana on mood in bipolar patients and to examine whether marijuana confers an additional negative impact on cognitive function.”

Study Finds THC Inhibits Weight Gain

By NORML

budcannabisCalgary, Canada: THC administration prevents weight gain in mice fed a high fat diet, according to preclinical trials data published in the journal PLOS ONE.

Investigators at the University of Calgary and at the Centre for Addiction and Mental Health in Ontario assessed the impact of small, daily doses of THC in diet-induced obese mice. They reported that THC intake inhibited increased fat. They concluded, “Chronic THC treatment … prevented high fat diet-induced increases in body weight.”

Study: Marijuana Genetics Often Mislabeled

purpleplantBy Paul Armentano, NORML

Strains of cannabis sativa or cannabis indica possess relatively few significant genetic differences and are often mislabeled by breeders, according to an evaluation of marijuana taxonomy published online last week in the journal PLOS ONE.

Investigators from the University of Manitoba, the University of British Columbia, and Dalhousie University in Nova Scotia evaluated the genetic structure of diverse range of commonly cultivated marijuana and industrial hemp samples.

Study: Cannabis May Treat Obstructive Sleep Apnea

A study publishedairway this week by the journal PLoS One, and published online by the National Institute of Health, has found that cannabis may provide a treatment option for obstructive sleep apnea (OSA).

For the study, researchers at the University of Illinois took rats with a form of sleep apnea and injected them with cannabis receptor antagonists (meant to mimic the effect of cannabinoids), as well as THC (tetrahydrocannabinol).

Study: Cannabinoids May Protect Against Cardiovascular Consequences of a High Fat Diet

A study published this month in the journal PLoS One, and published online by the U.S. National Institute of Healthcannabis, has found that cannabinoid receptor signalling – which is enhanced through the intake of cannabinoids – may actually protect against some of the negative effects of a high fat diet.

According to the study’s abstract, researchers; “investigated whether sleep-wake and diet-dependent cardiorespiratory control is altered in mice lacking CB1 [cannabinoid] receptors. CB1 receptor knock-out (KO) and intact wild-type (WT) mice were fed standard diet or a HFD [high fat diet] for 3 months, and implanted with a telemetric arterial pressure transducer and electrodes for sleep scoring.”

Study: THC Reduces Methamphetamine-Induced Brain Damage

A new study published in this month’s issue of the journal PLoS ONE, and published online by the National Institute of Health, has found that THC (Δ9-tetrahydrocannabinol) cancannabisthc reduce and even prevent brain damage caused by methamphetamine intake.

According to the study, titled Δ9-tetrahydrocannabinol prevents methamphetamine-induced neurotoxicity, “Methamphetamine (METH) is a potent psychostimulant with neurotoxic properties. Heavy use increases the activation of neuronal nitric oxide synthase (nNOS), production of peroxynitrites, microglia stimulation, and induces hyperthermia and anorectic effects.”

New Study: Legalizing Medical Cannabis May Reduce Homicides

A new study published this week by the journal PLOS ONE has found that legalizing medical cannabis doesn’t lead to an increasejillybean in crime, and may decrease homicides and assaults.

For the study, researchers at the University of Texas used data from FBI’s Uniform Crime Reportexamining crime rates across the country over a 16 year period. They then “analyzed the association between state MML [medical marijuana laws] and state crime rates for all Part I offenses collected by the FBI.”

Cannabis May Provide Treatment for Hodgkin Lymphoma

A new study published in the journal PLoS One as well as the National Institute of Health has found thatcannabuddy cannabis may serve as a treatment for Hodgkin lymphoma, which is a cancer of lymph tissue (found in the spleen, liver, bone marrow and other areas).

For the study, researchers at Goethe-UniversityLeipzig University and Martin-Luther-University Halle-Wittenberg “examined the distribution of CB1  [cannabinoid receptor 1] protein in primary cases of HL (Hodgkin lymphoma). Using lymphoma derived cell lines, the role of CB1 signaling on cell survival was investigated.”

Cannabinoids Can Treat Acute Lung Injury, According to New Study

A new study published in the journal PLOS One as well as the National Institute of Health has found that cannabinoids can be an effective treatment for acute lung injury, or acute respiratory distress syndrome (ARDS)bud, which is a condition caused by damage or disease to the lungs, which is often life-threatening.

The study, which was conducted by researchers at the University of São Paulo, found that: “MAGL inhibition, and consequently the increase in 2-AG levels [a naturally-occurring cannabinoid], produced anti-inflammatory effects in a murine model of LPS-induced ALI, a finding that was considered a consequence of the activation of the CB1 and CB2 receptors.”
