Insufficient evidence exists for the use of medical cannabis for most conditions for which its use is advocated, but various US state governments recommended it for over 50 medical conditions, Boston’s Beth Israel Deaconess Medical Center and Harvard Medical School found. The lack of evidence was separately confirmed by NICE in the UK.

Nearly one in four Arizona teens have used a highly potent form of marijuana known as marijuana concentrate, according to a new study by Arizona State University researchers.
Among nearly 50,000 eighth, 10th, and 12th graders from the 2018 Arizona Youth Survey, a biennial survey of Arizona secondary school students, one-third (33%) had tried some form of marijuana, and nearly a quarter (24%) had tried marijuana concentrate.
Marijuana concentrates have about three times more THC, the constituent of marijuana that causes the "high," than a traditional marijuana flower. This is concerning because higher doses of THC have been linked to increased risk of marijuana addiction, cognitive impairment and psychosis, said the study's lead researcher, Madeline Meier, an ASU assistant professor of psychology.
The research team also found that teens who used concentrates had more risk factors for addiction…They found that teens who had used marijuana concentrates were worse off on every addiction risk factor.
The study "Cannabis Concentrate Use in Adolescents," is published in the early online edition (Aug. 26, 2019) of Pediatrics.
The team…also found that teens who had used concentrates had much higher rates of e-cigarette use. One explanation for this might be that teens are using e-cigarettes to vape marijuana concentrate, according to Meier. Earlier studies, including those by Meier, have shown that youth put marijuana in e-cigarettes to conceal their marijuana use.
"Vaping marijuana can be passed off as nicotine vaping," Meier explained.
"What concerns me most is that parents might have no idea that their child is using marijuana, especially if their child is using marijuana concentrate," said Meier. "Marijuana is not harmless, particularly for adolescents."

Canada was the second country in the world to legalize marijuana (Uruguay was the first). The legalizing act calls it “cannabis” of course. So much more genteel than marijuana, eh? “Cannabis” sounds scientific, well-researched – while marijuana sounds kind of louche and stoned, too close to low-rent, pejorative sobriquets like pot, weed, hash, grass, ganja, reefer et al.
But it’s still marijuana, and I still call it that, because the people who worked hardest to get it legalized did their best to bypass or suppress the actual scientific research that would have slowed legalization down or even stopped it.
Since legalization last October, usage has increased, as one might expect. In the first quarter of 2019, there were 646,000 new users, mostly male, mostly over age 45. Many of the new users are doubtless assuming that the government scrupulously and objectively investigated marijuana’s effects on human health, and that they can be confident no harms will come to them with moderate usage.
That is not the case. Unlike other substances like tobacco and alcohol, where complete transparency on scientific consensus has created hyper-awareness of their inherent perils in the population, marijuana is a substance so swathed in stakeholder propaganda and ideology that the average Canadian, bombarded by claims of pot’s harmlessness and/or therapeutic value, is steeped in ignorance of marijuana’s epidemiologically tracked physical and mental risks.

The study is among the first to report on voluntary oral THC consumption in animals, a method of consumption that is similar to the way humans take the drug.
In a recently published paper in Drug and Alcohol Dependence, researchers at IUPUI and Indiana University Bloomington said they found the mice were less active, and their body temperatures were lower, after consuming the edible THC.
Marijuana edibles can elicit extreme, adverse reactions, Smoker said. Many of the commercially made marijuana-based products have a relatively higher concentration of THC than does marijuana plant material. In some cases, people are unsure how much of a marijuana edible they should eat and end up eating more than they should.
