   近日,一篇名为《留学生吸笑气成瘾 身体垮掉坐轮椅回国》的新闻报道引起社会关注,文章中,一位在美国留学的中国女生因为偶然机会经朋友推荐吸食笑气后,便一发不可收拾,吸食成瘾,导致身体机能受损,最终只能中断学业,坐着轮椅回国。


  让留学生成瘾的“笑气”到底是啥?
  Chinese student Lin Na (not her real name) got hooked on laughing gas while studying in the U.S., resulting in serious injury.
  中国学生林娜(化名)在美国学习期间吸食笑气成瘾,导致身体机能严重受损。
  笑气(laughing gas),学名一氧化二氮(nitrous oxide),在室温下是无色(colorless)、无味的不可燃气体(odorless non-flammable gas)。温度升高后,可成为很强的氧化剂(powerful oxidizer)。
  因为具有麻醉效果(anaesthetic effects),一氧化二氮曾经被广泛应用于外科和牙科治疗;也因为吸入此气体之后,人会产生愉悦的感觉(euphoric effects),所以才会得名“笑气”。此外,一氧化二氮还可用作火箭推进剂中的氧化剂(oxidizer in rocket propellants),以及赛车时提升发动机的动力输出(increase the power output of engines)。
  据媒体报道,年轻人吸食“笑气”时先将气体冲进气球,然后抱着气球吸食,这种气球被称为“嗨气球”(dizzy balloons)。
  “笑气”进入血液后会导致人体缺氧,长期吸食可能引起高血压(high blood pressure)、晕厥(syncope),甚至心脏病发作(heart attack)。长期接触此类气体还可引起贫血(anemia)及中枢神经系统损害(central nervous system injury)等。如果超量摄入,很可能因为缺氧导致窒息死亡(die of suffocation)。
  目前,笑气尚未列入我国麻醉药品品种目录(catalogue of narcotic 1 drugs)、精神药品品种目录(catalogue of psychotropic drugs)。国家食药监局曾发布一份关于“吸入笑气”的界定通知,明确标注吸入笑气镇痛装置被列为第三类医疗器械。
