2012年,经过投票表决,美国科罗拉多州和华盛顿州使大麻合法化。国家药物滥用研究所(NIDA)主任Nora Volkow表示,这一突然和前所未有的政策转变使NIDA陷入了“红色警报”。尽管向21岁以下的青少年人群出售大麻是非法的,但随着公众对大麻接受度的提高,越来越多的青少年有可能吸食大麻。目前尚不清楚大麻是否会对青少年大脑发育造成影响以及何种影响。

随着新法律的出台和脑成像技术的发展,Volkow决定加快推出一项雄心勃勃的计划——持续10年跟踪1万名美国青少年以弄清大麻、酒精和尼古丁是否会对其大脑功能和行为产生影响。

该计划预计耗费3亿多美元,将是迄今为止最大规模的青少年脑成像纵向研究。密苏里州圣路易斯华盛顿大学心理学家Deanna Barch说:“这是一个早该进行的计划。但缺点是,这相当于把所有鸡蛋放在一个篮子里。”

该项目的具体操作方式仍不确定。6月,NIDA和项目资助方——国家酗酒与酒精中毒研究所、国家癌症研究所和儿童健康与人类发展研究院召开了一次计划会议。科学家决定招募10岁左右的青少年作为参与者。

每隔两年,研究者会对其进行大脑成像及精神和认知测试,分析遗传和环境风险等因素。为了能招募到足够多的可能吸食毒品的参与者,该项目的参与者将主要来自高危人群,例如社会经济地位较低家庭的儿童和父母吸毒的儿童。

新型毒品竟然都是这些世界制药巨头发明的!

昨天最大的娱乐八卦是什么?柯震东、房祖名被爆出吸食毒品被抓。细数起来,今年北京因吸毒被抓的艺人已经不下10人。这些平时活跃在银屏上的身影一个个去演《监狱风云》了,不免令人感到可惜。 不可否认的是,现在吸毒的种类大部分都集中于新型毒品,也就是我们常说的冰毒、摇头丸这一类。在吸毒人员中,吸食新型毒品的人群已经占到近三分之一。 新型毒品从毒理学上可分为四类: 第一类
