People who use marijuana were found to have higher levels of lead and cadmium in their blood and urine, in comparison to those who do not use weed, according to a new study. The team of researchers at Columbia University analysed data from blood and urine samples collected between 2005 and 2018 as part of the National Health and Nutrition Examination Survey, a program conducted by the National Center for Health Statistics. They looked at samples of 7,254 people who said they had used marijuana in the last 30 days. Participants were examined for levels of heavy metals and 358 people were found to have 27 per cent higher blood lead levels than those who said they didn’t use either marijuana or tobacco. There were also 22 per cent higher levels of cadmium in those marijuana users according to the research, which was published Wednesday in the journal Environmental Health Perspectives. Researchers also found that the urine samples showed similar results. High levels of cadmium can cause stomach irritation, abdominal cramps, nausea, vomiting and diarrhoea, according to Better Health. Researchers found that although tobacco is the main source of cadmium exposure in the general population, the study showed similar exposure levels among cannabis users. “For both cadmium and lead, these metals are likely to stay in the body for years, long after exposure ends,” Tiffany Sanchez, an author of the study and an assistant professor of environmental health sciences at Columbia’s Mailman School of Public Health said to NBC News. As cannabis plants can absorb heavy metals from soil - the new findings demonstrate that heavy metals in cannabis plants can also wind up in the human body. “Previous studies have measured metals in marijuana plants, products, or marijuana smoke,” study authors have said. Lead exposure can be particularly harmful to children and pregnant women. In adults, chronic exposure to lead increases the risk of high blood pressure, heart problems and kidney damage. “Our study wasn’t able to tease apart whether or not self-reported cannabis users were using medical or recreational cannabis, so we can’t say definitively if medical cannabis users specifically had higher metal levels,” Sanchez said as reported by CNN. “This is something that should be evaluated in future studies.” Heavy metals bind to parts of your cells that prevent your organs from doing their job, according to the Cleveland Clinic and symptoms of heavy metal poisoning can be life-threatening and can cause irreversible damage. “Immunocompromised people, such as those going through chemotherapy, may be at greater risk from metal exposure or from other common cannabis contaminants like molds. However, this is very much an understudied area,” Sanchez added. On Wednesday, the Department of Health and Human Services recommended that the Drug Enforcement Administration ease restrictions on marijuana by moving it from Schedule I drug to Schedule III. HHS Secretary Xavier Becerra said on X, the platform formerly known as Twitter, that the agency has responded to President Joe Biden’s request “to provide a scheduling recommendation for marijuana to the DEA.” “We’ve worked to ensure that a scientific evaluation be completed and shared expeditiously,” he added. Senate Majority Leader Chuck Schumer said in a statement that HHS had recommended that marijuana be moved from a Schedule I to a Schedule III controlled substance. “HHS has done the right thing,” Schumer said. “DEA should now follow through on this important step to greatly reduce the harm caused by draconian marijuana laws.” Rescheduling the drug would reduce or potentially eliminate criminal penalties for possession. Marijuana is currently classified as a Schedule I drug, alongside heroin and LSD. According to the DEA, Schedule I drugs "have no currently accepted medical use in the United States, a lack of accepted safety for use under medical supervision, and a high potential for abuse."

Wild boar in southeastern Germany have long contained high levels of radioactive substances, which has been attributed to the 1986 Chernobyl nuclear disaster. But as radioactivity levels have fallen in other animals, they have stayed much the same among boar. Now, scientists have worked out the secret behind the so-called “wild boar paradox”. Research shows there is another culprit for the high levels of radioactivity: nuclear weapons tests from the mid-20th century. And both the weapons and the nuclear reactor meltdown continue contaminating the boar because of their diet. While the muscular boar seem healthy, the dangerous levels of radioactive caesium, the main contaminator, have prompted people to stop hunting them. In turn, there is now an overpopulation issue. “Our work reveals deeper insights into the notorious radio-cesium contamination in Bavarian wild boars beyond the total radionuclide quantification only,” radioecologist Felix Stäger from Leibniz University Hannover wrote in a paper. After a nuclear incident, radioactive materials can pose a significant threat to ecosystems. This happened after the Chernobyl meltdown in 1986, where there was an increase in radioactive caesium contamination. The main component of this, caesium-137, has a half-life of about 30 years, meaning it loses its radioactivity fairly quickly. However, caesium-135, which is created via nuclear fission, is far more stable. It has a half-life of more than 2m years. The ratio of cesium-135 compared to cesium-137 can help us work out where the cesium came from. A high ratio indicates nuclear weapon explosions, while a low ratio points to nuclear reactors like Chernobyl. So the researchers analysed caesium levels from 48 wild boar meat samples from 11 regions of Bavaria. It turns out that nuclear weapons testing was responsible for between 12 per cent and 68 per cent of the unsafe contamination in the samples. “All samples exhibit signatures of mixing,” wrote the researchers. “Nuclear weapons fallout and [Chernobyl] have mixed in the Bavarian soil, the release maxima of which were about 20−30 years apart.” So while Chernobyl remains the main source of caesium in wild boar, about a quarter of the samples showed enough contributions from weapons fallout to exceed safety limits even before the reactor meltdown comes into account. And because wild boar eat so many truffles, it has been exacerbated. The fungus absorbs high levels of contamination from both sources. Wild boars' diets, which include underground truffles, have absorbed varying levels of contamination from both sources, which has contributed to the animals' persistent radioactivity. “This study illustrates that strategic decisions to conduct atmospheric nuclear tests 60−80 years ago still impact remote natural environments, wildlife, and a human food source today,” the authors concluded. The study was published in Environmental Science & Technology. Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

Young-adult romance would seem like a fertile genre for Netflix's periodic adventures in interactivity, allowing viewers to make decisions for the protagonist and even select the guy they'd like to see her pick. Yet "Choose Love" strains the storytelling to fit the gimmick, in a special that does its central character no favors by making her race through the trio of suitors suddenly in her life.

Raheem Sterling has been omitted from the England squad while Eddie Nketiah was handed a first senior call-up by Gareth Southgate for the games against Ukraine and Scotland. Sterling, who missed the summer internationals when he said he did not feel in the right condition to play, was a candidate for a recall after starting the season in fine form for Chelsea but Southgate preferred Eberechi Eze of Crystal Palace. Southgate said it was a tough phone call and Sterling was left annoyed to be omitted, revealing: “It was a difficult call and Raheem is not particularly happy about it.” The England manager, who also chose Phil Foden, Jack Grealish, Marcus Rashford, Bukayo Saka and James Maddison ahead of Sterling, explained that he wanted to stick with the players he used for the June wins over Malta and North Macedonia. “To bring Raheem back in we have to leave someone else out and on the basis of three games [of the league season] I don’t think anyone deserves to be left out,” he added. “It is really good to see Raheem start the season so well and he looks fit and hungry but in those attacking positions behind the No 9 we have a lot of competition.” Arsenal striker Nketiah, who has scored 16 goals for England’s Under-21 team, was selected ahead of Aston Villa’s Ollie Watkins as the third specialist striker behind Harry Kane and Callum Wilson. “We want to have a look at him,” Southgate said. “He is a young player with a lot of pedigree, a really good finisher and the record goalscorer in the Under-21s.” The manager also kept faith with Harry Maguire and Kalvin Phillips, who have played no first-team football for Manchester United and Manchester City respectively, with defensive injuries a reason why he picked the former. Southgate said: “With Harry Maguire we have lost a lot of experience in terms of caps at centre halves, we are giving some less experienced players a chance to come into the squad but Tyrone [Mings] is out for most of the season, John Stones is out of this camp, Eric Dier is not in Tottenham’s squad, Conor Coady is in the Championship now so there is a space there. With Harry and Kalvin Phillips, it is not ideal they are not playing football. Declan Rice is the only English player to start this weekend as a single pivot and Kalvin is the next best option.” Jordan Henderson, who has moved to Al-Ettifaq in Saudi Arabia, retained his place in the squad with Southgate saying his international future could depend on the standard of the Pro-League. “The key as we move forward is the physical intensity of the league,” said Southgate. “Because of the heat as well, whether that will allow him to perform at the level we need; that is a huge consideration.” In a defence without the injured Stones, Mings and Luke Shaw, there were call-ups for Fikayo Tomori, Marc Guehi, Lewis Dunk and the uncapped Levi Colwill. “He is doing really well,” Southgate said of Colwill. “He is progressing. We really liked him at the end of last season with Brighton. He had a really good tournament with the Under-21s so he showed under pressure he could cope. He has started well with Chelsea in a slightly different position.” Full squad Goalkeepers: Sam Johnstone (Crystal Palace), Jordan Pickford (Everton), Aaron Ramsdale (Arsenal) Defenders: Trent Alexander-Arnold (Liverpool), Ben Chilwell (Chelsea), Levi Colwill (Chelsea), Lewis Dunk (Brighton), Marc Guehi (Crystal Palace), Harry Maguire (Manchester United), Fikayo Tomori (AC Milan), Kieran Trippier (Newcastle United), Kyle Walker (Manchester City) Midfielders: Jude Bellingham (Real Madrid), Conor Gallagher (Chelsea), Jordan Henderson (Al-Ettifaq), Kalvin Phillips (Manchester City), Declan Rice (Arsenal), Eberechi Eze (Crystal Palace) Forwards: Phil Foden (Manchester City), Jack Grealish (Manchester City), Harry Kane (Bayern Munich), James Maddison (Tottenham Hotspur), Eddie Nketiah (Arsenal), Marcus Rashford (Manchester United), Bukayo Saka (Arsenal), Callum Wilson (Newcastle United) Read More Manchester United left with Luke Shaw injury dilemma Why are England wearing their blue kit against Spain?
