This year is the second in which the Monitoring the Future survey asked high schoolers about vaping specific substances: nicotine, marijuana or "just flavoring."Flavoring was the most commonly reported substance among eighth-graders at 15.1%, followed by nicotine at 10.9% and then marijuana at 4.4%.Tenth-graders reported identical rates for flavoring and nicotine, but 12.4% reported vaping marijuana. Among 12th-graders, 29.7% reported vaping nicotine, 25.7% flavoring and 13.1% marijuana."You're seeing right now that 30% of 12th-graders last year were exposed to nicotine," Volkow said."Another issue of concern is, these devices are very efficient at delivering drugs rapidly into your brain and, in so doing, deliver the drugs in ways that make them more addictive -- and so it's not just nicotine. Now we also know that they are using it for 9THC," or tetrahydrocannabinol, a cannabinoid chemical in marijuana, she said.Bonnie Halpern-Felsher, a professor of pediatrics in Stanford University's Division of Adolescent Medicine, called this increase in vaping alarming but not surprising because of new products, such as those from popular e-cigarette maker Juul."However, since MTF doesn't appear to separate out vaping vs. Juuling in their survey, it is hard to know what the youth are using," Halpern-Felsher said of the new report."The overall decline or stabilization of other drug use is promising, although the increase in vaping marijuana is concerning," she said. "Clearly, youth drug prevention messages needs to go beyond conventional drugs and include all forms of nicotine and vaping."The overall increase in vaping in the survey appears to be consistent with data from the US Centers for Disease Control and Prevention showing a 78% increase in youth vaping between 2017 and 2018, said Dr. Pamela Ling, a professor of medicine at the University of California, San Francisco, who works with the school's Center for Tobacco Control Research and Education and was not involved with the new report.The Food and Drug Administration "has also recognized an 'epidemic' of youth vaping. The consistency of these data suggests this is a real problem," Ling said."While we see declines in cigarette smoking among youth, the increases in vaping may lead to overall rates of tobacco or nicotine use increasing. We also know from many longitudinal studies of youth that those who use e-cigarettes are about three times more likely to start smoking cigarettes," she said. "The increase in vaping goes against the trends for all other drugs and alcohol, which are declining. That's a problem."In historical context, "the absolute increases in the prevalence of nicotine vaping among 12th-graders and 10th-graders are the largest ever recorded by Monitoring the Future in the 44 years that it has continuously tracked dozens of substances," the authors of the report wrote in a letter to the editor Monday in the New England Journal of Medicine.Meanwhile, the traditional use of cigarettes remained at the lowest levels in the survey's history.Daily cigarette use was reported by 0.8% of eighth-graders, 1.8% of 10th-graders and 3.6% of 12th-graders in 2018, the survey showed. Lifetime cigarette use among 12th-graders went down from 26.6% in 2017 to 23.8% in 2018, and past-month use declined from 9.7% to 7.6%.In general, substances at historic low levels of use in 2018 were alcohol, cigarettes, heroin, prescription opioids, MDMA (ecstasy or Molly), methamphetamine, amphetamines, sedatives and ketamine, according to the report. 3539

There was wrong campaign spending, but it was not done by me. I have trust in the justice system despite what's going on with Trump and Mueller, and the anti-Republican, pro-Democrat forces within the Department of Justice, at the highest levels, and the FBI, at the highest levels. I'm optimistic on the outcome … it's been a year, that's a long time, said Hunter. 365

told her Ukrainian officials were alarmed in August that US security aid was being held up — an indication Kiev was aware of the delay earlier than it was reported publicly, according to a deposition transcript released Monday.Laura Cooper, the Pentagon's deputy assistant secretary for Russia, Ukraine and Eurasia, told lawmakers behind closed doors last month that she met with Volker in August to discuss the hold on aid. She said Volker told her in their meeting that he was attempting to lift the hold on the aid by having the Ukrainians deliver a public statement that they would launch the investigations being sought by President Donald Trump.She described Volker seeking a statement from the Ukrainians about opening investigations into election interference that would trigger a release in the aid."I knew from my Kurt Volker conversation and also from sort of the alarm bells that were coming from Ambassador (Bill) Taylor and his team that there were Ukrainians who knew about this," Cooper said, describing the Ukrainians as aware of the freeze on aid in August 2019. "The context for the discussion that I had with Ambassador Volker related specifically to the path that he was pursuing to lift the hold would be to get them to make this statement, but the only reason they would do that is because there was, you know, something valuable."Cooper's deposition was one of three transcripts released Monday by House Democrats. They also made public the interviews last month of two former deputies of Volker, 1521
