中国坊间流传一名高三女生，因没法静下心完成学业，其母亲便给她服用“聪明药”，结果她成绩短时间内飞跃提升，考进班级前10名。消息引起家长们热议，不少家长都试图买“聪明药”，惟医生指出，所谓“聪明药”的主要成分哌醋甲酯，与冰毒主要成分相似，实际是一种中枢神经系统兴奋剂，可促进脑内的多巴胺和去甲肾上腺素释放，惟大量服用易引起不良反应。

广西中医药大学第一附属医院脑病一区科主任胡跃强指出，学生服用“聪明药”后会兴奋、精力充沛，不容易疲劳，惟对于“提升记忆力，提高学习成绩”根本毫无帮助。他续指，含哌醋甲酯的药物主要用于治疗儿童注意力缺陷综合症或嗜睡症，早被卫生部门列入第一类精神药品名单，是受到严格管理的处方药。

另胡医生又指，由于哌醋甲酯的作用机制，和冰毒的主要成分苯丙胺类似，同样有上瘾性，会愈吃愈上瘾，且服用剂量愈来愈大，如停止服药，就会出现一种“负性神经调节作用”，

因此没有经过医生的指导服用会很危险，很容易走上吸毒的歧途。

他建议，学生有学习精神压力大的状况，是很正常的心理反应，可以寻找心理医生或者精神科的医生治疗，而不能盲目去购买所谓的“聪明药”，一定要选择正规的医院进行治疗。
