美国疾控中心证实:美国青少年正在用电子烟吸大麻

研究表示，若将这一估算比例应用于全美，那就意味着200多万名年轻人可能都曾用电子烟吸过大麻。如果只考虑那些承认自己抽过电子烟的学生，这一比例还会增加：约三分之一的高中生称，他们曾用电子烟吸过大麻。对于抽电子烟的初中生而言，这一比例为四分之一。

"The use of marijuana in these products is of particular concern because cannabis use among youth can adversely affect learning and memory and may impair later academic achievement and education," Katrina Trivers, CDC epidemiologist and lead author of the study, told The Verge in an email. The National Academies of Sciences, Engineering, and Medicine agree, warning in a report last year that getting blazed can dull memory and learning at least over the next day or so, the report says.

"用这些产品吸食大麻一事值得引起大家的关注，因为青少年时期吸食大麻会对学生的学习和记忆力带来不利影响，或影响未来的学业成绩和教育，"疾控中心的流行病学专家及本研究的首席作者卡特里娜·特拉弗斯在写给The Verge网站的一封邮件中说道。美国国家科学院，工程院和医学院同意这一观点，并在去年的一份报告中警告称：吸食大麻至少会使你在接下来的一天中记忆力变差、学习迟钝，研究报道。

But there's still a lot to learn about the long-term risks - particularly of vaping cannabis products, says Gideon St. Helen, a clinical pharmacologist at the University of California, San Francisco who was not involved in the CDC survey. There are compounds in cannabis, for example, "that we have no idea what happens to them when heated in an e-cigarette," St. Helen says in an email to The Verge. There also tend to be higher levels of THC in cannabis extracts, hash oil, and waxes compared to the regular plant, he says: "For young, inexperienced users, acute cannabis intoxication is a concern."
