In a study published this week in the journal Economic Inquiry, researchers found that the legalization of adult-use cannabis reduced opioid overdose deaths by 21%. “Our principal finding is that recreational marijuana access significantly decreases opioid mortality, with the most pronounced effects for synthetic opioids,” the researchers concluded. The effect “stems primarily from access via dispensaries […]

CBDV, or cannabidivarin, is one of many molecules derived from cannabis and hemp plants. Like CBD, CBDV is not intoxicating when isolated, so it won’t cause the euphoric high associated with high-THC cannabis. Much of the research around CBDV has centered around its effect on seizures. GW Pharmaceuticals, which developed the first FDA-approved CBD drug […]

Up to 30 percent of veterans develop the symptoms of PTSD throughout their lifetime. That’s roughly 11 to 20 returning veterans out of every 100 from the Gulf War, and up to 30 out of every 100 from the Vietnam war. There is no cure for PTSD. But recently scientists have made breakthroughs in understanding how PTSD can […]

A new study found that “adolescent cannabis use is not associated with structural brain differences in adulthood.” The researchers added: “Even boys with the highest level of cannabis exposure in adolescence showed subcortical brain volumes and cortical brain volumes and thickness in adulthood that were similar to boys with almost no exposure to cannabis throughout […]

Mixed martial arts league Ultimate Fighting Championship has announced the details of their partnership with Aurora Cannabis for clinical trials to study the efficacy of CBD on wound care, recovery, injury, pain, and inflammation. Dr. Duncan French, UFC vice president of performance, said the collaboration with Aurora “is the best way to educate ourselves and […]

It’s official – cannabis use does not make you stupid. A 2012 study that found that cannabis lowers IQ has just been refuted by new research. What is notable is that the scientists involved in the original 2012 research has reversed her earlier findings. Even when the research was originally published, the same journal published […]

A new study shows that the cannabis extraction process, as sophisticated as it may be, removes significant active ingredients from the plant-based source material — including the material that, for most consumers, determines what strain is their favorite. For the Planta Medica article, a research team led by Michelle Sexton used liquid chromatography to see […]

Why does marijuana cause one person to experience a pleasurable high, and another to experience paralyzing paranoia? A July 5 study out of Western University in Ontario, Canada, may bring us one step closer to an answer. Published in Scientific Reports, the study is one of the few to explore what it deems the “divergent […]

The U.S. government is growing the largest crop of research marijuana in five years, responding to interest in varieties with high levels of THC and CBD. Scientists have asked for weed that more closely matches what’s sold in states that have legalized medical or recreational marijuana, the National Institute on Drug Abuse said in an […]

Smoked cannabis and tobacco do not differ immensely from the compounds they emit when combusted, despite some folklore. Agreeably, organically grown cannabis does not contain some of the more frightening additives of cigarettes. For example, acrolein (or tear gas), is found in cigarettes to increase the availability of nicotine. The smoke of cannabis, defined as […]

There’s nothing worse than going through the months of time and labor to grow your own cannabis only to discover mold on it. But identifying mold on your cannabis can be harder than you think. It’s important to protect your own health and the health of those who might be consuming your product, to ensure […]

Researchers have found that the number of women in the United States who use cannabis during pregnancy is increasing, according to a study published this week in the medical journal JAMA. The percentage of pregnant women who had used cannabis the month prior to completing the survey increased from 3.4 percent in 2002 to 7 percent in […]

Scientists in Australia found that CBD killed all the strains of bacteria they tested in a lab, including some which are highly resistant to existing antibiotics. What’s more, the bacteria did not become resistant to the drug after being exposed for 20 days: the period when bacteria can survive currently used drugs. The team tested […]

A recent study from the University of Arkansas, where mice died after being given CBD, may change the public’s perception of CBD. But it shouldn’t. The study dosed mice on CBD to see what would happen to the little guys’ livers. Because mice are much smaller than humans, the researchers “allometrically scaled” the doses so […]

The total number of suicides in California per year, including those committed with firearms, declined after the state legalized marijuana use for medical purposes, according to a new study. Researchers observed a notable decline in intentional deaths in the years after Prop 215 was approved. “Our results demonstrate that California’s 1996 intervention led to an […]

A compound called delta-8-THC is becoming increasingly common in concentrated extracts at marijuana dispensaries. But from where did this long-lost sibling of delta-9-THC seemingly suddenly appear? See the original article at Cannabis Now

A recent U.S. survey found that if cannabis were made federally legal, 85% of consumers would use it as a treatment option for specific ailments, not necessarily just for recreation. The survey found 67 percent of respondents believed cannabis was “healthier” than their over-the-counter and prescription drugs. 69 percent said they believed cannabis was “more […]

Researchers at Washington State University have mapped the gene networks that regulate the production of cannabinoids and terpenoids found in cannabis trichomes. By creating unique genetic fingerprints for each strain, the researchers say improved breeding techniques, proper strain identification, and the testing of various CBD health claims and the validity of the synergistic entourage effect […]

It’s long been known that cannabis plants are indigenous to Central Asia, but a new study provides a fresh focus on where exactly this genus may have first evolved millions of years ago. According to researchers, “These data converge on the northeastern Tibetan Plateau, which we deduce as the cannabis centre of origin, in the […]

A new study produced by a Colorado researcher threatens to upset one of the supposed scientific certainties about impairment and blood-THC levels. In the study, each subject tested positive for THC, but when comparing blood drawn from different parts of the body, researchers found dramatic disparities in THC levels. They also found disparities in THC […]

In a recent study, gastric fluid was made artificially and adjusted to pH 1 (which is that of the actual gastric fluid) and CBD was dissolved in methanol. About 85% of the present CBD isomerized to a mixture of D9- and D8-THC. Theoretically, because of similar chemical structure between CBD and THC, the possibility of […]

A recently published review, “Joints for Joints – cannabinoids in the treatment of rheumatoid arthritis,” cautiously concludes that “cannabinoids could be a suitable treatment for RA.” The authors also suggest a series of molecular approaches that merit future clinical studies. See the original article at Forbes

Researchers at the University of Northern Colorado found that the cannabis supplied by the only federally authorized cultivation site in the country shared a closer “genetic affinity with hemp samples in most analyses” than what commercial dispensaries are selling in legal states. The DEA has only ever authorized one grower: the University of Mississippi, which […]

A new study analyzing 320,000 medical records found that drinkers who smoke weed had significantly lower odds of developing liver diseases including hepatitis, cirrhosis, steatosis, and even hepatocellular carcinoma, a type of liver cancer. Alcohol abusers who didn’t use weed had about a 90 percent chance of developing liver disease, whereas light cannabis-using heavy drinkers […]

According to a new study published in the journal Cannabis, in certain circumstances marijuana use can lead to positive experiences for couples. The study’s authors asked 183 married or cohabiting couples who consumed regularly to track their use for 30 days. In their analysis, the study’s authors determined that shared cannabis experiences increased the likelihood of […]

A new study published in Translational Psychiatry, concluded CBD could represent “a completely new mechanism in the treatment of schizophrenia.” The Phase II study was randomized, controlled, and double-blind. Forty two “acutely exacerbated schizophrenic patients” were randomly assigned to a three-week treatment of CBD or a standard antipsychotic medication (amisulpride). In progressive steps, the patients received up to […]

A new Italian study that looked at how different storage methods affected the deterioration of THC (cannabis’s intoxicating compound) over time shows that freezing cannabis is the most effective way to keep your marijuana fresh. Cannabis stored at room temperature in a bright room lost 13 percent of its THC content after 100 days. Meanwhile, cannabis stored […]

A recent study published in JAMA Psychiatry, which analyzed data from a group of 1,037 New Zealanders followed from their birth until age 38, found that long-term cannabis use didn’t seem to have any lasting effects on physical health. The only bad effects pot seemed to have were on the teeth. At age 38, people who used […]

Researchers at the University of New Mexico (UNM) recently solved a major gap in scientific literature by using mobile software technology to measure the real-time effects of actual cannabis-based products used by millions of people every day. Contrary to popular media-reports and scientific dogma, the psychoactive chemical, tetrahydrocannabinol or “THC,” showed the strongest correlation with […]

A new study evaluating data collected by the World Health Organization has found that strict drug laws don’t do anything to prevent young people from using cannabis. The study was conducted by University of Kent professor Alex Stevens and looked at data collected from over 100,000 individuals across 38 countries. While many people have argued that loosening […]

An estimated 85 percent of women experience some type of mood disturbance during the postpartum period. Lack of sleep, chronic pain, hormone imbalances and other physical changes, coupled with the sudden intense responsibility of a new life, can result in significant damage to a woman’s mental health. To mitigate these feelings of despair and to increase mindfulness, […]

It’s no secret that many cannabis users believe that smoking before turning on a favorite album or watching a movie can enhance the artistic experience, but why is that? Dr. Ethan Russo, a cannabis researcher from Prague, says it all has to do with how cannabis affects memory. As Russo explains, THC reduces a person’s ability […]

A recent study conducted by Swiss researchers from the Institute of Forensic Medicine at the University of Bern found that dabbing did a much better job of getting the total amount of available THC and CBD into your lungs than smoking. In fact, the study published in Forensic Science International found that joints waste 300 percent more THC than dabs. The study […]
