First, the good news. Teen smoking is still at the lowest point since the Monitoring the Future survey began 44 years ago. Only 3.6 percent of high schoolers are smoking daily, down from more than 22 percent a couple decades ago. Binge drinking is down, adolescents are using drugs like cocaine¹ and MDMA at historically low levels, and, despite the ongoing² opioid epidemic³, less than 1 percent of high school seniors use heroin⁴. Plus, the percentage of seniors using prescription⁵ opioids dropped to 3.4 percent from 4.2 percent a year earlier. When it comes to marijuana, the rates have held steady for the past few years despite increasing marijuana legalization. "We are not seeing decreases in marijuana, but we are not seeing increases," says Nora Volkow, director of the National Institute on Drug Abuse (NIDA), at a press conference.

首先，让我们来聊聊好消息。自监测未来（Monitoring the Future）于44年前开展调查以来，青少年吸烟人数已达到史上最低。只有3.6%的高中生会每天抽烟，而几十年前这一数据为22%以上。酗酒人数也有所减少，吸可卡因嗑摇头丸等药物的青少年人数也处于历史最低水平。尽管阿片类药物持续存在，但只有不到1%的高中生吸食海洛因。此外，使用处方阿片类药物的高中生比例已从去年的4.2%降为3.4%。尽管大麻合法化程度不断提高，但过去几年高中生吸大麻的比例一直处于稳定状态。"吸大麻的数量未有减少，但也不曾增加，"国家药物滥用研究所（NIDA）主任诺拉·沃尔科在新闻发布会上说道。

"SOMETHING ABOUT THIS DEVICE REALLY APPEALS TO KIDS."

"电子烟的某些特点对小孩子特别有吸引力。"

For Volkow and others involved in the survey, the new concern is that these positive trends might be reversed by the rapid rise of vaping. From 2017 to this year, the number of seniors who reported vaping in the past 30 days jumped from 11 percent to 21 percent. That's the largest single increase that the Monitoring the Future study has seen in its history, says Richard Miech, the survey's principal investigator⁶ and a member of University of Michigan's Institute for Social Research.

沃尔科和参与调查的其他人员担心这些积极的趋势可能会因为电子烟的迅速发展而逆转。从2017年至今，过去30天称自己吸电子烟的高中生人数已从11%增长为21%。这是监测未来所见证过的史上最高的一次增长，调查的首席研究员、密歇根大学社会研究所的成员理查德·米奇说道。

About 37.3 percent of seniors reported vaping at all in the last year, up from 27.8 percent of seniors the year before last year. And whereas teens used to just vape flavors, now they're getting more adventurous⁷. "Anything that can be vaped, it doesn't matter," says Meich. "Nicotine⁸ vaping went up, marijuana vaping went up." For example, 13.1 percent of seniors reported vaping marijuana in the past year, up from 9.5 percent. "Something about this delivery device really appeals to kids," Meich adds.

大约37.3%的高中生称自己去年吸了电子烟，高于前年的27.8%。以前，青少年抽的只是味道，但现在抽电子烟却更像是一种冒险。"无所谓，你可以抽任何东西，"梅奇说。"尼古丁电子烟可以吞云吐雾，大麻电子烟也可以吞云吐雾。"例如，13.1%的高中生称自己去年吸了大麻，高于前年的9.5%。"电子烟的某些特点对小孩子特别有吸引力，"梅奇补充道。
