我们的读者遍布全球，每个角落都会遇到一些紧急状况。绝大部分地区的读者需要面对随机大麻尿检的威胁，就算大麻合法化的地区，也存在可能因为工作需要而接受尿检，比如美国。美国在联邦层面上，大麻依然属于管制药品，就算在大麻合法州，为联邦工作的职员也需要不定期接受尿检。其中检测是否使用过大麻是最常规内容。使用大麻多久可以通过验尿测试？就成了大麻食客关心的问题。
这个问题看似简单，但却挺不好回答的。
我们先来了解背景知识。大麻尿检主要是检测尿液中的大麻素THC（四氢大麻酚）的代谢物THC-COOH（Δ9-去-四氢大麻酚羧酸）。当我们抽大麻的时候，身体会迅速吸收其中的THC，在让我们颅内高潮的同时，THC被代谢成为THC-COOH，然后随着尿液排出体外。抽大麻摄入的THC，大约有15-20%会通过这种代谢方式排出体外。
所以大麻尿检的本质就是在检测身体是否依然在进行着这一代谢过程。这个代谢过程受到很多因素的影响。

THC的摄入量。也就是上一次飞的有多高，或者石化的有多久。一般情况下，越高，越久，则表明大麻THC含量高，需要越多的时间去代谢掉。
抽大麻的习惯。偶尔抽一次大麻，少则5天，多则8天，就无法从尿液中检测出THC-COOH了。但如果经常抽，情况就很复杂了。一项研究表明，如果一个人每天都使用大麻，在停止使用后，用了77天才通过大麻尿检。
下面总结给大家参考
非常偶尔抽大麻： 5-8天可以通过尿检
每周2-4次：11-18天可以通过尿检
每周5-6次：33-48天可以通过尿检
每天都抽：55-65天，甚至更久才可以通过尿检
如果你需要尽快将体内的大麻代谢物清理干净，可以考虑使用一些专业的排毒药，可以在7天内，甚至是几个小时内就清除大麻代谢产物THC-COOH。
吃大麻制品会不会需要更久的代谢时间？尽管答案是肯定的，但也只是会比抽大麻多几个小时，最多一天。这是因为食用大麻制品，THC会先被代谢成为11-羟基-四氢大麻酚（THC-OH），之后在代谢成为THC-COOH。这就使得食用大麻会让THC在身体内需要更久的时间才可以代谢完毕。
这个代谢过程和我们身体情况也同样有关系，如果是代谢快的体质，那么身体排出THC-COOH的速度也会快一些。如果是一般体质，那么，多喝水，也可以增加身体的代谢速度，从而尽快将THC-COOH排出。
需要快速排出体内的THC，还可以考虑采用快速排毒药物
